Guide to Diabetes in Cat

The information presented in this article is for educational and informational purposes only and does not constitute or substitute for the advice of your veterinarian.

Diabetes mellitus in cats, commonly known by the shortened name “diabetes,” sugar diabetes,” or “sugar,” is one of the most common medical disorders. As a pet owner with a newly diagnosed cat with diabetes, it is difficult to know what you need to do. We created this article to help you know step by step what you need to do.

The 6 keys to treatment for diabetes in cats include:

  1. Change your cat’s diet
  2. If your cat is overweight – help your cat lose weight! (this is critical)
  3. Give insulin every 12 hours
  4. Monitor for response to treatment
  5. Maintain a consistent diet, exercise, and insulin treatment plan
  6. Monitor for complications of the disease

We will help you understand more about diabetes, how and when to give insulin, and how to deal with complications. We also included answers to the most common questions diabetic cat owners have as they start their journey.

What Is Diabetes?

Diabetes is a disease that leads to chronic elevation of the blood glucose or sugar. Blood sugar is maintained by a group of hormones, the most important of which is insulin, which is manufactured by the pancreas, a small organ near the intestines. Insulin lowers the blood sugar after a meal, and deficiency of insulin, or an insensitivity of body cells to available insulin, leads to diabetes.

With maintenance and care, your cat can have a very good life with diabetes. We will help tell you how.

What Types of Cats Get Diabetes?

Diabetes mellitus usually affects middle-aged to older cats of either sex. The peak age seen in cats is 11 years. Juvenile-onset diabetes may occur in cats less than 1 year of age but is uncommon. Any breed can be affected but some breeds are at higher risk.

Breeds at increased risk for diabetes mellitus include Burmese cats.

What Causes Feline Diabetes?

The cause of diabetes has a lot to do with genetics and bad luck. There are risk factors which can potentiate diabetes such as obesity, recurring pancreatitis, Cushing’s disease (hyperadrenocorticism), and drugs such as glucocorticoids and progestogens that antagonize insulin.

What Are Common Signs of Diabetes in Cats?

Common diabetes in cats symptoms and signs include thirst and increased water consumption among others.

Uncontrolled elevation of glucose leads to dehydration and body chemistry disorders that can eventually cause coma and death. Left uncontrolled, diabetes can become life threatening.

Why Does My Diabetic Cat Urinate More?

When a pet is diabetic, the body tries hard to fix the problem. For example, the kidneys will try to get rid of excess glucose in the urine. To get rid of extra glucose they also end up getting rid of a lot of extra water. So, they urinate more, are thirstier, and drink more.

The medical terms for this are polydipsia (drinking more) and polyuria (urinating more).

What Does the Term Spilling Glucose Mean?

Some clients hear their vet say this term – their cat is “spilling glucose.” This term means that their cat has glucose in the urine. This is the body’s way of trying to get rid of excess glucose in the cat’s blood.

How Is a Diagnosis Obtained?

The first step in treating diabetes in your cat is getting a correct diagnosis. This requires a veterinary examination and appropriate tests, such as a urinalysis (to detect spilled “sugar”) and blood glucose determination. Additional tests are often needed to assess the overall medical situation. Once the diagnosis is made, however, you and your veterinarian can work together to effectively control diabetes mellitus.

What Type of Diabetes Does My Cat Have?

There are two basic forms of diabetes: type I and type II. Absolute deficiency of insulin leads to type I diabetes. This is due to an insufficient number of insulin-producing pancreas cells. Type I diabetes, often called “juvenile-onset diabetes” in people, represents the most serious form of the disease. Effective treatment for type I diabetes requires a combination of controlled diet, regular exercise, and insulin therapy.

Cats are most often affected by type I diabetes and rarely have type II. People and pets with type I diabetes require daily injections of insulin to maintain a regular blood-sugar level.

Adult onset or type II diabetes is the more common form of diabetes in people. This condition combines a relative lack of insulin production with a resistance of body cells to the effects of the hormone. Type II diabetes is treated with a combination of diet, weight control, and medicine that makes cells more sensitive to insulin. This form of diabetes is observed more often in cats than in dogs. Keys to successful treatment are a high-fiber diet, weight control, and (occasionally) medicines designed for humans to control the glucose level.

How Do I Treat Diabetes?

The treatment of diabetes requires the administration of injectable insulin to drive sugar molecules into the body’s needy cells. Dietary changes will help.

In cats, weight loss and dietary changes will often suffice for long term treatment of diabetes. You will need to learn how to give your cat insulin as well as how, what, and when to feed your cat. For cats that are extremely ill, they will require hospitalization until diabetes is under control.

What Should I Expect from My Vet?

Every veterinary clinic and vet are a little different in how they schedule rechecks following the diagnosis of diabetes.

One approach is as follows (and may vary with your individual veterinarian):

Will My Diabetic Cat Need to be Hospitalized?

If your pet has stopped eating, has been vomiting, and is generally not doing well, they will be admitted into the hospital to begin treatment. This often happens when the diabetes mellitus has progressed, and the body produces ketones.

Because the body has not been able to use glucose as its energy source, it will begin to use its fat instead. When the body burns fat for energy, a by-product known as ketones is created and unfortunately, is toxic. Ketones can be found in urine samples.

Once ketones are present, the animal will continue to decline rapidly unless treatment begins. The presence of Ketones changes the diagnosis to Diabetic Ketoacidosis, which can be complicated to treat.

Diabetic ketoacidosis (DKA), the most severe form of Diabetes Mellitus, results in severe changes in blood chemicals including imbalances in small, simple chemicals known as electrolytes.

In-hospital therapy generally includes insulin administration with frequent dose adjustment (every few hours), intravenous (IV) fluids, administration of electrolytes (blood chemicals), treatment of secondary problems, and antibiotics. Multiple blood glucose samples are taken to determine the insulin dose and urine samples to determine the presence of ketones. The insulin given in this situation is a short acting insulin and will not be the insulin used when you go home.

The process is slightly different with every cat but will generally require two to four days of intense hospitalization.

What Are Signs of Diabetic Ketoacidosis (DKA)?

Symptoms include weight loss, lack of appetite, increased thirst, frequent urination, lethargy, disorientation, vomiting, and a fruity smell to the breath (acetone odor).

If you suspect your cat is having symptoms of DKA, this is a life-threatening emergency. Call your veterinarian immediately. Treatment includes hospitalization, intravenous fluids, and frequent doses of short-acting insulin.

Beginning Treatment with Your Diabetic Cat

If your pet is still feeling good and eating with no vomiting, you will be taught to give insulin injections to your cat and start them on a special diet. Below is information on what and when to feed your diabetic cat.

The goal of diabetes treatment is to control the blood glucose so it is close to the normal range, as it would be if the pancreas were still producing insulin naturally.

In cats, the ultimate goal is for diabetic remission. This is possible in diagnosed obese or previously obese cats. Dietary therapy and weight loss are essential in addition to insulin therapy.

What Diet Should I Feed My Diabetic Cat?

Your cat’s weight and what your cat eats have a direct impact on their blood glucose levels. Diet is thought to be a CRITICAL part of diabetes management in cats.

Current research suggests that a high protein, low carbohydrate diet is best for cats. Cats are obligate carnivores, and they don’t have the proper enzymes to digest plant-based protein. So, offering them plant-based foods can be difficult for the diabetic cat to digest and process. Feeding to obtain ideal body weight is critical.

Excellent foods include:

Previously, diets high in fiber and complex carbohydrates were recommended for dietary management of diabetic cats. These are no longer recommended.

Several studies have shown that cats who started on insulin and a high-protein and low-carbohydrate diet were 4 times more likely to achieve clinical remission of their diabetes. In cats that did not achieve remission, their insulin requirement was reduced by half.

Canned diets are significantly lower in carbohydrate content than most dry kibble and often can help in better dietary management of diabetes.

IMPORTANT: The most important aspects of a diabetic diet are that it is complete, balanced, liked by your cat, meets calorie needs, and consistent. Feed the same food and the same number of calories every day. This will help keep glucose levels steady.

How Do I Calculate How Many Calories My Cat Should Eat Per Day?

Your vet can help you with this. Here is a method for calculating your cat’s calorie requirements.

Can I Treat My Cat with Diabetes Pills?

Oral anti-hyperglycemic pills are commonly used in humans to treat adult-onset type II diabetes. Some cats can respond to oral medications for milder cases of diabetes with very strict weight loss and diet modifications. Some studies suggest it can take 3 to 4 months for cats to optimally respond to oral medications. Common medications used in cats include Glipizide.

Severe cases of diabetes are only controlled with insulin injections.

My Cats Hates Their New Food, What Should I Do?

If your cat won’t eat their new food, go back to their regular food for a period of time. It is important that your cat eats. Then, make a gradual change to their new food. Mix in 10% of the new food with 90% of the old food. Each day, add a few more kibbles of the new food to the old food until you have obtained a 100% transition to the new food. If they still will not eat the new diet, refer to the list of recommended foods above and discuss a different option with your veterinarian.

When Should My Cat Eat?

For cats that are getting insulin twice daily, it is recommended to split the daily calories into two meals, which are fed before the insulin dose.

For cats on once daily insulin, they should be fed twice daily with the first meal before the insulin injection and the second meal at the time when the insulin peaks, which can be determined based on knowledge of the insulin and the glucose curve.

Most diabetic cats are fed twice daily. Give ½ of the daily calories approximately 30 minutes before the insulin injection. After your cat eats, their blood glucose will naturally increase. The insulin will help drive the glucose levels back to a normal level. Give the other half of the daily calories before the second insulin injection (this is assuming you are giving insulin every 12 hours).

Another method is to feed your diabetic cat ¼ of their daily calories in the morning before the insulin injection, and another ¼ of the calories 6 hours later when the insulin is peaking. Follow that with another 1/4 of the calories at dinner and the last fourth 6 hours later.

Can I “Free Feed” My Cat?

Free feeding is a term that refers to having food in the bowl all the time and allowing your cat to eat when they want.

Many cats with diabetes are on a strict, consistent feeding schedule. However, this can be difficult for some cats. This may work better for cats that are nibblers and not food motivated.

Scheduled feedings work best on cats even though they may prefer small frequent meals. The idea behind meal feeding is that you can observe your cat and ensure they eat prior to insulin administration.

For cats that want to eat more frequently, you can use timed feeders so your cat can eat several times during the day, but you can still control calorie intake.

Can My Cat Get Treats?

Diabetic cats can get treats as long as they are approved by your vet. Generally, treats that are low in sugar and carbohydrates are OK. Larger treats can even be broken up into small pieces to provide multiple treats.

Treats can be given as a reward for blood glucose testing or when the blood glucose is at its lowest – approximately 4 to 8 hours after injection.

Good treat options include baby carrots, snap peas, broccoli, cauliflower, green or red peppers, canned pumpkin, tofu, a kibble of your cat’s regular cat food, and/or freeze-dried meat treats. Recommended commercial treats include Stella & Chewy’s Carnivore Crunch or other all-natural freeze-dried meat or fish treats.

Some diabetic cat owners make their own treats by taking an approved canned cat food and using that as the base. They will generally empty the can onto a cookie sheet, smash down to about ¼ to ½ inch thickness, and bake at 375 degrees Fahrenheit until dry and crispy. Some foods can be refrigerated and sliced, then baked the same way. Store baked treats in the refrigerator in a sealed container.

The calories in the treats should be considered as part of the overall calorie requirements for the day and given in moderation.

How Should I Exercise My Cat?

Regular exercise is good for your cat. It can help lose or maintain weight and lower blood sugar.

The best approach to exercising your diabetic cat is to do it regularly and routinely. Try to do the same amount of exercise every day at the same time.

Large changes in exercise routines can change insulin requirements. An unusually long or vigorous play session can cause the blood sugar levels to drop too low. If you plan a change in your cat’s routine, do it slowly and gradually.

What Is Insulin?

Insulin is a hormone that is formed and released by beta cells residing in the pancreas. Eating prompts the release of insulin. When insulin is not produced in sufficient quantities, it can be administered in the form of an injection.

There are various types of insulin treatments, each with a different duration of effectiveness.

A bottle of insulin is commonly referred to as a vial. All insulins are measured in units.

There are two common concentrations, which will be important when you buy your insulin syringe. Some insulins are u-100 (100 units in a milliliter), and others are u-40 (40 units in a milliliter). Because insulins are different, 3 units of one insulin may not be the same as 3 units of a different insulin. It is very important to verify the type of syringe and insulin match when filling your prescription to avoid over- or under-dosing your pet.

There are several different types of insulin used on cats. They differ by what they are made from (some are pork, some are human based) and how long they act in the body. The short acting insulins are referred to as “regular,” medium acting are referred to as “Lente,” and long-acting insulins are referred to as “Ultralente”.

The insulin used in cats is generally different from dogs.

The most used insulins in cats are:

NOTE: There are several types of insulin on the market. What works on one pet may not work on another.

How Often Does My Cat Need Insulin?

Your veterinarian will determine this but based on the insulin’s available in the U.S. for cats, the most effective treatment for diabetes in cats is administration of insulin with intermediate duration of action twice daily.
The only currently available intermediate-duration product is recombinant human neutral protamine Hagedorn (NPH) insulin.

Another type of insulin can be used called Porcine Lente insulin (Vetsulin). At the present time, it is not being sold in the United States due to problems with stability and bacterial contamination associated with the manufacturing process. Based on our sources, it is uncertain when or if the product will again be available in the United States.

Why Does My Cat Need Insulin?

Insulin is required for food to be properly processed and utilized as energy for the body. Insulin lowers blood sugar after a meal. Deficiency of insulin, or an insensitivity of body cells to available insulin, leads to sugar diabetes in cats.

The goal of diabetes treatment is to supplement the insulin to regulate the blood glucose in as close to a normal range as possible.

How Should Insulin Look?

The first time you open your insulin – look at the color and clarity of the bottle, most types of insulin will look slightly cloudy but there should be no clumps or floating particles.

How Much Insulin Do I Give My Cat?

The initial dose of insulin given is 1/8 to 1/4 of a unit per pound of body weight given every 12 hours.

For example, a 10-pound cat may start on 1 unit of insulin total. A lower dose is generally recommended with a gradual increase. It is better to start low and gradually allow the body to acclimate to the disease and avoid signs of hypoglycemia (low blood sugar).

How Do I Give an Insulin Injection?

Insulin is generally given under the skin (subcutaneously) over the back. The location of the injection should be rotated with every injection. The general method for giving insulin is as follows:

Gather your equipment to give the insulin injection. The bottle of insulin, syringe, cotton ball, alcohol, and your glasses if you wear them (It can be difficult to see the small print on the numbers).

What If I Get Air in My Syringe?

Air in the syringe means that you will not get the correct dose of insulin.

If you are drawing up your insulin and you see you are getting air, inject the insulin (and air) that is in the syringe back in the bottle. Try again. You can sometimes gently tap the syringe (flick the syringe case with your index finger) to encourage the air bubble to go to the top to dispose.

If you have taken the insulin out of the bottle and notice that there is air in the syringe, the best approach is to dispose of that insulin and pull up the correct dose.

When Should I Give Insulin?

Most cats are on twice daily insulin. This should be given 12 hours apart. As you start therapy on your diabetic cat, pick a time that works for you that is 12 hours a part. For some pet owners, this may be 6 am and 6 pm. For others it may be 4 am and 4 pm. Whatever works for you is fine. Try to give the insulin within an hour of the scheduled dose time.

If you give insulin once daily – give it at the same time every day.

How Do I Store My Cat’s Insulin?

Every insulin is slightly different. Most of them are sensitive to light. Some manufacturers recommend that the insulin be stored in the refrigerator and others are ok at room temperature. It should always be stored out of direct light. I generally recommend that when you open a new box with insulin – mark the date on the box with permanent marker and keep your insulin stored in the box.

All insulins are sensitive to extremes in temperature such as heat and freezing. Review the manufacturer’s recommendations for storage and for expiration dates.

Most used insulins have the following recommendations:

How Long Does Insulin Last?

Please follow the recommendation from your veterinarian. Some insulin manufacturers recommend a new vial be started every 30 days and others recommend every 3 months. Realistically, very little insulin is used in 30 days for most cats. This is the ideal recommendation.

Most veterinarians recommend that the cat owner examine the insulin daily to ensure there are no clumps, particles that won’t dissolve, or an abnormal color. Dispose of the bottle when it expires (check date on the bottle) or 6 months after it is opened. Most insulin has been found to stay effective for this time.

It is possible that as insulin ages, it becomes less effective.

When opening a new bottle, write the date on the bottle or box and in your calendar.

Why Do I Need to Roll the Insulin Bottle?

It is recommended to gently “roll” the insulin bottle to disperse the powdered insulin in the liquid. Shaking can damage the insulin molecules.

To roll the bottle, place it between the palms of your hands and gently roll it between your palms 2 to 3 times. This is enough to disperse the insulin.

If you draw a dose of insulin that isn’t properly mixed, you may either get too much or not enough of the proper concentration. Some insulin settles out very quickly, so it is recommended to gently roll the bottle between your palms a few times to disperse the contents, then immediately draw the insulin in the syringe.

Why Can’t I Shake My Cats Insulin?

Gently rolling of the insulin between your palms is all that is needed to mix the insulin. Insulin is a very fine powder that is suspended in the liquid.

Rolling the insulin is better for two reasons:

How Much Insulin Should I Keep on Hand?

It is recommended that you keep a spare vial of insulin on hand. This way if you happen to be out or drop and break a vial, you have a spare.

Diabetic pet owners will tell you it is no fun trying to find insulin on the weekend if something happens.

Can I Freeze My Insulin to Preserve it?

Insulin is delicate. Freezing will render the insulin inactive.

My Insulin has Clump or Particles That Aren’t Dissolving

If you notice clumps in your insulin, particles that won’t dissolve, an abnormal color, or anything else that seems suspicious, stop using that vial and dispose.

Open a new insulin bottle for use.

What Type of Insulin Syringe Should I Use on My Cat?

There are three things you need to know when buying insulin syringes.

  1. Type of insulin (U-40 or U-100)
  2. Size of the needle (gauge)
  3. Volume you want the syringe to hold (generally come in ½ milliliter or 1 milliliter (ml)

Type of Insulin

It is critical that you use the insulin syringe that matches the insulin. Most insulin types used in cats are what they call U-100 insulin. This means there are 100 units of insulin in a volume of 1 ml. The insulin syringes should indicate they are also U-100. Some of these syringes will hold ½ ml (50 units) and others will hold 1 ml (100 units). If your cat is on more than 50 units per dose of the U-100 insulin, you will need the 1 ml syringe.


Some insulin is U-40 (which means there are 40 units in a milliliter) and should only be used with U-40 syringes. Using the wrong syringe type can cause either a massive overdose or underdose of medication. Again, it is critical that you use the insulin syringe that matches the insulin.

Size of the Needle

The gauge is the size of the needle diameter. The lower the number, the bigger the needle. The higher the number, the smaller the needle. A 31-gauge needle is smaller than a 29-gauge needle (although both are very small). To put it in perspective, most blood is drawn with a 22-gauge needle. The smaller needle is generally preferred, but some needles can be too small and have difficulty going through the skin of some thicker-skinned pets.

Volume Size

Syringes generally come in a ½ ml and 1 ml volume size. This means the syringe will hold less with a ½ ml syringe and more with a 1 ml syringe. If your cat is on a small dose of insulin such as under 25 units of the U-100 insulin – it is easiest to use the 50-unit syringe. It is easier to see the numbers and be accurate when pulling up the insulin dose.

When you go to the pharmacy to buy syringes make sure you buy the one that works with your insulin. Know if you need U-100 or U-40.

A commonly used syringe is a 31 gauge (which is a very small needle). For example, this is a common syringe size that cat owners like:

U-100 – Ultra thin 31-gauge 0.5 cc – 5/16” short needle

What If I have U-40 Insulin and U-100 Syringes?

There is a formula to convert U-40 and U-100 syringes. Go to this Link.

How Do I Convert Insulin Units to Milliliters?

Ideally, if you have insulin and syringes that match – you don’t need to do this. Mistakes happen when pet owners start trying to do various conversions.

I have a chart that will help you. Go to: How to Convert U-100 Insulin in Units to Milliliters.

Where Can I Buy Insulin Syringes?

You can buy your insulin syringes from your vet or at most pharmacies. You don’t need a prescription to buy them. You can also buy them online at several pharmacies. Choose a pharmacy with which you are familiar and comfortable. It is important to be frugal but there have been reports and recalls of insulin syringes that are mismarked from low-cost syringe producers.

Insulin syringes are cheapest by the carton, which contains 100 syringes.

How Many Times Can I Use an Insulin Syringe?

Insulin syringes are made to be disposable, to be used once and tossed. However, we as veterinarians and pet owner care givers are frugal. Boxes of 100 needles run about $20 to $45 dollars depending on where you shop.

If you are using 2 syringes a day – that is 60 syringes a month.

Ideally, use the syringe once. This minimizes the chances of infections that can be caused by a dirty needle. If you must reuse the syringe, use them only twice. The needles dull quickly because they are made to be used once. When they are dull, it is more uncomfortable for your cat, and that may make him resent the injection.

I Accidentally Bent the Needle on the Insulin Syringe – Can I Bend It Back?

The insulin syringe needles are very fine and fragile. They will bend easily, but don’t bend them back. Because they are so thin, bending them back can create a weak spot that can break. What can happen is that you bend it back, give the injection, and that additional stress on the needle makes the needle break off in the cat’s skin.

If the needle bends regularly, try a needle that is a little stronger. This means you would pick a gauge size that is a lower number. If you are using a 31-gauge needle, try a 29 gauge and see if that bends less and is easier for you to use. This slight difference doesn’t make a difference in comfort for most cats.

Some pharmacies offer free syringe samples. This is a great way to see what works best for you and your cat.

My Syringe Needle Accidentally Touched Something – What Do I Do?

If you have drawn up your insulin in the syringe and it touches your finger, table, or anything else, the best and safest thing to do is to throw it away and start over.

I Drew Up the Insulin and Now Can’t Find My Pet. Now What?

If you rolled the bottle and the contents were mixed properly before mixing up the insulin, it should be OK in the syringe for a few hours. If your insulin is normally stored in the refrigerator, store the syringe in the refrigerator with the needle side tilted up. This prevents the needle from clogging.

Before injecting, gently tilt the syringe up and down then administer. If it is more than 2 hours, dispose of the insulin.

Should I Recap the Syringe?

Recapping syringes is a big “no-no” in human medicine due to the risk of human HIV and hepatitis. These diseases are not a problem in cats but in general, re-capping syringes is not recommended to prevent you from sticking yourself.

If you re-cap a syringe, keep one hand stable and move one hand to recap. If you are moving both hands at the same time, there is a higher risk of sticking yourself.

They make needle clippers that remove the needle but these need to be used with care, as the small needle bits can be dangerous.

The safest approach may be to not re-cap your syringe and dispose of it immediately in a sharp's container.

What Do I Do with My Used Syringes and Lancets?

You can dispose of your needles, syringes, and lancets a few different ways. You can buy “sharps” containers similar to what they use in human and veterinary hospitals. The sharps containers are thick plastic that cannot be punctured. You simply place the syringe and needle in the box until it is full. When it is full, you close the top to secure. “Sharps” containers can be purchased at some pharmacies and online.

Some pet owners use a plastic milk jug, empty laundry detergent bottle, or large soft drink bottle as their sharp's container. When full, secure the lid and tape. This can then be placed in your regular trash. Most homes produce very few sharps, and this container can then be disposed of in your regular trash (after it is sealed). Check the rules for your area. A website that can help in determining the regulations in your area is http://www.safeneedledisposal.org

How Many Times Can I Use the Lancet?

Lancets are made to be used one and thrown away. Ideally, use them once and toss. If you must reuse the lancet, it is recommended to use them only twice. The needle edge dulls quickly because they are only made to be used once. When they are dull, it is more uncomfortable for your cat, which may make them resent the testing.

How Much Insulin Should I Give If My Cat Won’t Eat?

I’d recommend that you ask your vet this question, but the answer is generally as follows:

What If I’m Late Giving Insulin?

On occasion, you may forget to give your cat insulin or are unable to get home.

If you are unable or forget to give your cat’s insulin at the regular time, these are the general recommendations:

When Should My Cat Be Rechecked at the Vet?

You should call your veterinarian anytime you have questions, any time your cat has symptoms of high or low blood sugar, or approximately one week after any change in the insulin dose.

If things are going well, a glucose curve should be performed after the first week of insulin administration. A glucose curve is a test where a blood sample is taken every 1 to 2 hours for approximately 12 hours to determine how high or how low the blood glucose is. This can be completed in the veterinary hospital or at home.

If your vet is doing the monitoring, go to: Preparing Your Cat For a Glucose Curve at the Vet Hospital.

Once the results are complete, your veterinarian will interpret the results and give you a recommendation for the dose of insulin.

Other times the doctor may recommend additional testing to rule out other metabolic diseases that make diabetes more difficult to control.
