Guidelines for Treating Hypoglycemia

What is hypoglycemia?
Hypoglycemia is when a person has low blood sugar. Blood sugar is low when it falls below 70
mg/dl. Some people may experience symptoms of hypoglycemia at blood sugar levels greater
than 70 mg/dl.

How would I know if my blood sugar is low?
Symptoms of low blood sugar (hypoglycemia) include:
ξ Sweating
ξ Becoming shaky
ξ Feeling hungry
ξ Headache or light-headed
ξ Irritable or crabby

If a person does not treat their hypoglycemia their blood sugar will fall lower and they may
ξ Confused
ξ Very tired
ξ Unconscious (pass out)

How can my blood sugar go too low?
Hypoglycemia can happen when a person is taking oral medicine or insulin to lower the blood
sugar and treat their diabetes. Blood sugars can go too low when a person:
ξ Takes too much insulin
ξ Exercises without eating
ξ Drinks alcohol
ξ Does not eat enough food
ξ Eats a meal later than usual
ξ Skips a meal

How do I treat low blood sugar?
Do not wait to treat low blood sugar. If you feel your blood sugar is low you need to treat it as
soon as you can. Start by checking your blood sugar. If you feel low and are not able to check
your blood sugar quickly, treat the low blood sugar anyway. It is better to have your blood sugar
go a little high than to have it go too low.

You will want to treat your low blood sugar by eating or drinking something that contains fast-
acting sugar with 15 grams of total carbohydrate per serving. 15 grams of carbohydrate will
raise your blood sugar 50-60 mg/dl in 10-15 minutes.


Good choices of 15 grams of carbohydrates are:
ξ ½ cup apple juice
ξ ½ cup orange juice
ξ 5 Lifesavers®
ξ 2 pieces of hard candy
ξ 1 cup low-fat milk
ξ 1 Tablespoon honey
ξ 2 Tablespoons raisins
ξ ½ cup regular gelatin
ξ 6 sugar cubes
ξ 1 Tablespoon syrup
ξ 3- 4 glucose tablets
ξ ½ (80 gram) glucose bottle
ξ ½ (31 gram) instant glucose tube

Glucose tablets, instant glucose bottles and tubes can be purchased at your local drug store.

After eating or drinking the fast-acting carbohydrate, wait 10 to 15 minutes and re-check your
blood sugar.

If you still feel your blood sugar is low, or if your blood sugar is still below 70mg/dL, repeat the
steps above. Try eating another 15 grams of carbohydrate until your blood sugar is higher than
100 mg/dl, or you feel better.

Try to eat a well-balanced meal with a source of slow-acting carbohydrate (whole grains) and
lean protein (chicken, fish, eggs, or low-fat dairy) within the next hour.

If your next meal is more than an hour away choose a healthy snack with a source of slow-acting
carbohydrate (whole grains) and lean protein.

Healthy snack options include:
ξ 1 cup low-fat milk
ξ Light yogurt
ξ ½ sandwich on wheat bread

ξ 6 Wheat crackers with 1oz cheese
ξ Apple and 1 Tablespoon peanut
Avoid over-treatment
Foods used in treating low blood sugar are extra foods that are not part of your meal plan. Foods
used to treat low blood sugars should not be viewed as “treats.” Chocolate candy is not a good
choice because it will not produce a rapid rise in your blood sugar.

Avoid Hypoglycemia
If you have low blood sugars often, think about why this may be happening. Ask yourself:
ξ Am I skipping meals and/or snacks?
ξ Am I counting carbohydrates correctly?
ξ Am I giving myself too much insulin, or taking my medicines incorrectly?
ξ Am I exercising without knowing my blood sugar?

If you have trouble figuring out why, be sure to ask your healthcare provider who may be able to
help you.


How do I prevent low blood sugars?
Prevent your blood sugar from going too low by:
ξ Eating meals at about the same time each day. Do not skip meals.
ξ Taking the correct amount of insulin or diabetes oral medicines.
ξ Eating a snack before exercise and before driving long distances (if you have not had a
meal for 2-3 hours).
ξ Knowing when your insulin will peak.
ξ Always carrying a form of fast-acting sugar to treat low blood sugar.

If a person with diabetes becomes unconscious or is not able to swallow, give him or her
glucagon rather than trying to make him or her eat or drink. Glucagon is a shot given into a large
muscle. It will increase the blood sugar levels in the body.
