Low Blood Sugar Treatments.


In most cases, a person can treat hypoglycemia him/herself when he/she recognizes the symptoms.

Treating an episode of low blood sugar

The immediate treatment for hypoglycemia is to take some sugary food or drink (about 15 to 20g of rapidly acting carbohydrate) to stop the attack.

For example, a person can take a glass of fruit juice or non-diet soft drink
between three (3) and five (5) dextrose tablets.

At first, consumption of fatty foods and drinks, such as chocolate and milk should be avoided, because these foods don’t usually contain as much sugar and the sugar they contain may be absorbed more slowly by the body.

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

It usually takes around 15 minutes to get out from a mild episode of hypoglycemia.
If the patient has a blood glucose meter, he/she should measure his/her blood sugar again after 15 to 20 minutes. If it’s still too low (below 4mmol), the patient should have some more sugary food or a drink before testing his/her levels again in another 15 to 20 minutes.
