What to Ask Your Doctor About Insulin

continued...

When should I take my insulin?

There isn’t one simple answer to this question. It depends on things such as:

  • The type of insulin you use (fast-acting, premixed, etc.)
  • How much and what type of food you eat
  • How much exercise you get
  • Other health conditions you have
  • The type of insulin delivery system (such as shots, pump, or inhaler) you use

Your doctor may want you to take insulin a half-hour before meals, so it's available when sugar from food enters your bloodstream. Find out exactly when during the day you need to take each of your injections, and what to do if you forget to give yourself an injection.

If I inject insulin, does it need to be in a certain part of my body?

Most people inject it into their belly, since it’s easy to reach. Your insulin shot will work fastest if you inject it into your stomach. (Be sure to stay at least 2 inches from the belly button.) You can also inject insulin into your arms, thighs, or buttocks.

Ask your doctor or diabetes educator to show you the right way to inject, including how to keep your needle and skin clean to prevent infections. Also learn how to rotate the injection site so you don't develop hard, fatty deposits under the skin from repeated injections.

Does insulin affect other medicines I take?

Some drugs can intensify low blood sugars caused by insulin. Tell your doctor about all the medicines you take, even those you bought without a prescription.

What can I eat while taking insulin?

Ask your doctor for food recommendations to help your insulin work best. For instance, you’ll want to know how much to eat at each meal, which types of foods are best for you to eat, whether you need to have snacks, and when you should eat. If you drink alcohol, ask your doctor if that’s OK while you’re taking insulin, and what your limit should be.

What is my target blood sugar level?

Your doctor should tell you how often you need to check your blood sugar using your blood glucose meter. Find out your target blood sugar range before and after meals, as well as at bedtime. For most people with diabetes, the targets are:

  • 70 to 130 milligrams per deciliter (mg/dL) before meals
  • Less than 180 mg/dL 1 to 2 hours after the start of a meal

Your level is currently

If the level is below 70 or you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.

People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.

Congratulations on taking steps to manage your health.

However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.

Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.

Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.

One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
