When a diabetic experiences low blood sugar, in which the blood sugar level drops below 70 milligrams per deciliter, it's important to consume 15 grams of carbohydrates, such as three glucose tablets, half a cup of regular soft drink or fruit juice, or five to six hard candies, suggests MedlinePlus. One tablespoon of sugar, honey or syrup is also a good source of carbohydrates.
When treating low blood sugar, a diabetic should not eat more than the recommended amount of carbohydrates to avoid high blood sugar and weight gain, notes MedlinePlus. After 15 minutes, the next step is to check the diabetic's blood sugar level again. If he still experiences the symptoms of low blood sugar and his glucose level remains below 70 milligrams per deciliter, he should consume another 15 grams of carbohydrates. It is essential to contact a doctor immediately if these steps do not help regulate the diabetic's blood sugar levels.
Symptoms of low blood sugar include hunger, headache, sweating, shaking and a tired feeling, states MedlinePlus. A fast heartbeat, vision problems, difficulty thinking, and a cranky or anxious sensation are other common symptoms.
Diabetics who are taking medications such as insulin, glyburide and chlorpropamide are prone to low blood sugar, according to MedlinePlus. To prevent the condition, they should monitor their blood sugar levels regularly and bring snacks with them, especially when exercising.
