    Hypoglycemia, commonly referred to as “low blood sugar,” occurs when the amount of glucose in the blood falls below normal levels. Glucose is an important source of energy for the body. When your blood sugar level is too low, your brain cells and muscles do not have enough energy to function properly. Hypoglycemia can occur as a consequence of diabetes or as a reaction to a specific food eaten . It often results from a sudden drop in blood sugar levels. It can usually be treated quickly by eating a small amount of food containing glucose as soon as possible.

      Hypoglycaemia – How to Treat and Prevent Low Blood Sugar

      For people with type 1 diabetes, maintaining the correct blood glucose level involves balancing how much insulin you inject, the amount of food you eat, and how much energy you burn during exercise.

      Hypoglycaemia may occur if you’ve taken your dose of insulin as usual, but your carbohydrate intake is lower than normal or has been used up more quickly. This may happen if you delay or miss a meal or snack, don’t eat enough carbohydrate, or exercise more than usual.

      People with diabetes who’ve drunk too much alcohol, or drank alcohol on an empty stomach, can also get hypoglycaemia.


      However, it’s not always possible to identify why a particular episode of hypoglycaemia has occurred, and sometimes it happens for no obvious reason.

      How Can I Stop My Blood Sugar From Crashing

      Here are a few ways to avoid hypoglycemic episodes:

      • Get in the habit of self-monitoring your blood glucose. Keeping track of when your blood sugar drops can help you recognize aspects of your routine that may be contributing to your hypoglycemia. Dr. Klonoff recommends a continuous glucose monitor. Its the best tool for automatically checking your blood glucose levels around the clock, he says.
      • Change your meal plan. When, what, how much, and how often you eat all play a big part in your blood glucose levels. A dietitian can teach you about healthy, well-balanced food choices that will make it easier for you to maintain an acceptable blood sugar range.
      • Keep a stash of glucose tablets on hand. With your doctorâs recommendation, make sure you always have glucose tablets with you. You can stick them in your briefcase, purse, car, desk, school locker, etc. You may also want to keep snacks nearbyfor example, cheese or peanut butter crackers, although doctors suggest over-the-counter glucose tablets for more accurate dosage. Do not eat a healthy sugar-free candy bar during hypoglycemia, warns Dr. Klonoff. Its lack of sugar means that it will not raise your blood glucose level sufficiently when you want it to.
      • Certain drinks can help get your blood sugar up as well. Try 8 oz. of fruit juice, a soft drink , or a cup of milk.

      When Your Blood Sugar Gets Low

      Check your blood sugar whenever you have symptoms of low blood sugar. If your blood sugar is below 70 mg/dL, treat yourself right away.

      1. Eat something that has about 15 grams of carbohydrates. Examples are:

      • 3 glucose tablets
      • One half cup of fruit juice or regular, non-diet soda
      • 5 or 6 hard candies
      • 1 tablespoon or 15 mL of sugar, plain or dissolved in water
      • 1 tbsp of honey or syrup

      2. Wait about 15 minutes before eating any more. Be careful not to eat too much. This can cause high blood sugar and weight gain.

      3. Check your blood sugar again.

      4. If you do not feel better in 15 minutes and your blood sugar is still lower than 70 mg/dL , eat another snack with 15 g of carbohydrates.

      You may need to eat a snack with carbohydrates and protein if your blood sugar is in a safer range — over 70 mg/dL — and your next meal is more than an hour away.

      Ask your provider how to manage this situation. If these steps for raising your blood sugar do not work, call your doctor right away.

      When Should I Check My Blood Sugar During The Night

      • After a day with lots of exercise, such as swimming or sports
      • If your blood sugar was low before bedtime
      • When you are sick, especially if you have vomiting or diarrhea
      • If you have been waking up high every morning for 3 or more days
      • When your long-acting insulin dose has increased

      The best times to check your blood sugar during the night is about 3 to 4 hours after your bedtime snack, then again about 3 to 4 hours after that.

      Treating An Episode Of Hypoglycaemia

      Health: Important tips for diabetics: What to do if you ...

      The immediate treatment for hypoglycaemia is to have some sugary food or drink to end the attack.

      For example, this could be:

      • a glass of fruit juice or non-diet soft drink
      • between three and five dextrose tablets
      • a handful of sweets

      At first you should avoid fatty foods and drinks, such as chocolate and milk, because they don’t usually contain as much sugar and the sugar they do contain may be absorbed more slowly.

      After having something sugary, you should have a longer-acting carbohydrate food, such as a few biscuits, a cereal bar, a piece of fruit or a sandwich.

      It will usually take around 15 minutes to recover from a mild episode of hypoglycaemia. If you have a blood glucose meter, measure your blood sugar again after 15 to 20 minutes. If it’s still too low , you should have some more sugary food or a drink before testing your levels again in another 15 to 20 minutes.

      When treating someone else with hypoglycaemia, if the above treatment isn’t effective, you may be able to help them by applying glucose gel to the inside of their cheeks, and gently massaging the outside of their cheeks.

      It may take 10 to 15 minutes before they feel better. This shouldn’t be done if the person is drowsy or unconscious because of the risk of choking.
