Hypoglycemia In A Person With Diabetes
WHAT YOU NEED TO KNOW:
What is hypoglycemia?
Hypoglycemia is a serious condition that happens when your blood glucose (sugar) level drops too low. The blood sugar level is usually too high in a person with diabetes, but the level can also drop too low. It is important to follow your diabetes management plan to keep your blood sugar level steady.
What increases my risk for hypoglycemia?
- A missed meal, or a meal eaten later than usual
- Certain medicines, or too much insulin or other diabetes medicine
- More exercise than usual, without extra food
- Decreased liver or kidney function
What are the signs and symptoms of hypoglycemia?
- Headache, hunger, or nervousness
- Trouble thinking or moodiness
- Sweating, or a pounding heartbeat
- Forgetfulness, confusion, or double vision
- Weakness or trouble walking
- Numbness and tingling around your mouth
- Seizures or loss of consciousness
How do I manage hypoglycemia?
- Check your blood sugar level right away if you have symptoms of hypoglycemia. Hypoglycemia is usually 70 mg/dL or below. Ask your diabetes care team what blood sugar level is too low for you.
- If your blood sugar level is too low, eat or drink 15 grams of fast-acting carbohydrate. Examples of this amount of fast-acting carbohydrate are 4 ounces (½ cup) of fruit juice or 4 ounces of regular soda. Other examples are 2 tablespoons of raisins or 1 tube of glucose gel.
- 3/4 cup of cereal
- 1 cup of skim or low fat milk
- 6 soda crackers
- 1/2 of a turkey sandwich
- 15 fat-free chips
- Always carry a source of fast-acting carbohydrate. If you have symptoms of hypoglycemia and you do not have a blood glucose meter, have a source of fast-acting carbohydrate anyway. Avoid carbohydrate foods that are high in fat. The fat content may make the carbohydrate take longer to increase your blood sugar level. Ask your diabetes care team if you should carry a glucagon kit. Glucagon is a medicine that is injected when you develop severe hypoglycemia and become unconscious. Check the expiration date every month and replace it before it expires.
- Teach others how to help you if you have symptoms of hypoglycemia. Tell them about the symptoms of hypoglycemia. Ask them to give you a source of fast-acting carbohydrate if you cannot get it yourself. Ask them to give you a glucagon injection if you have signs of hypoglycemia and you become unconscious or have a seizure. Ask them to call the local emergency number (911 in the US) . This is an emergency. Tell them never to try to make you swallow anything if you faint or have a seizure.
- Wear medical alert jewelry or carry a card that says you have diabetes. Ask where to get these items.
How do I prevent hypoglycemia?
- Take diabetes medicine as directed. Take your medicine at the right time and in the right amount. Do not double the amount of medicine you take unless instructed by your diabetes care team.
- Eat regular meals and snacks. Talk to your dietitian or diabetes care team about a meal plan that is right for you. Do not skip meals.
- Check your blood sugar level as directed. Ask your diabetes care team what your blood sugar levels should be before and after you eat. Ask when and how often to check your blood sugar level. You may need to check at least 3 times each day. Record your blood sugar level results and take the record with you when you see your care team. Changes may need to be made to your medicine, food, or exercise schedules using the record.
- Check your blood sugar level before you exercise. Exercise can decrease your blood sugar level. If your blood sugar level is less than 100 mg/dL, have a carbohydrate snack. Examples are 4 to 6 crackers, ½ banana, 8 ounces (1 cup) of nonfat or 1% milk, or 4 ounces (½ cup) of juice. If you will exercise for more than 1 hour, you may need to check your blood sugar level every 30 minutes. Your diabetes care team may also recommend that you check your blood sugar level after exercise.
- Be aware of how alcohol affects your blood sugar level. Alcohol can cause your blood sugar level to drop for up to 12 hours after drinking. Ask your diabetes care team if alcohol is safe for you. If you drink alcohol, always have a snack or meal at the same time. Women should limit alcohol to 1 drink a day. Men should limit alcohol to 2 drinks a day. A drink of alcohol is 12 ounces of beer, 5 ounces of wine, or 1½ ounces of liquor.
When should I or someone else call the local emergency number (911 in the US)?
- You have a seizure or pass out.
- Your blood sugar is less than 50 mg/dL and does not respond to treatment.
- You feel you are going to pass out.
- You have trouble thinking clearly.
When should I call my diabetes care team?
- You have had symptoms of low blood sugar several times.
- You have questions about the amount of insulin or diabetes medicine you are taking.
- You have questions or concerns about your condition or care.
