Dizziness is a symptom of low blood sugar (hypoglycemia). If you are feeling symptoms of low blood sugar, eat or drink 15 to 20 grams of fast-acting carbohydrates. These are sugary foods or drinks without protein or fat that are easily converted to sugar in the body. Try glucose tablets or gel, ½ cup fruit juice, ½ cup regular (not diet) soda, 1 tbsp honey or sugary candy.
Talk to a health care professional about appropriate treatment options for low blood sugar.
