Low Blood Sugar

View Glucagon Tutorial

When your blood sugar falls below 70 mg/dL, you have low blood sugar (hypoglycemia). When this happens, many people experience unpleasant symptoms that can be both physical and emotional. These symptoms can come on quite suddenly. Hypoglycemia can be treated. However, if it is not dealt with quickly, these serious reactions may be life threatening and include passing out or having convulsions. Talk with your healthcare provider about what steps to take in case of a low blood sugar emergency, and most importantly, how to avoid one.

What causes hypoglycemia?
The most common causes of hypoglycemia are:

  • skipping or not finishing meals or snacks
  • getting more exercise than usual
  • taking too much diabetes medication, including insulin
  • eating at the wrong time for the medicine you take
  • drinking alcoholic beverages

Many medications can affect your blood sugar levels and insulin needs. Before you drink alcoholic beverages, discuss with your healthcare provider whether some use of alcohol may be included in your meal plan.

Symptoms of hypoglycemia

  • sweatiness
  • tiredness
  • hunger
