Shakiness and hunger, dizziness, anxiety, moodiness and irritability are among the earliest symptoms of hypoglycemia, or low blood sugar, according to Mayo Clinic. A person may also have a headache and increased sweating.
If early symptoms of hypoglycemia are ignored, they may progress to clumsiness or poor coordination, difficulty concentrating, numbness in the mouth or tongue, a loss consciousness and coma, explains WebMD. Additionally, blurred or distorted vision, muscle weakness, drowsiness, difficult or slurred speech and seizures may occur, notes Mayo Clinic.
Treatment of hypoglycemia involves eating or drinking 15 to 20 grams of glucose or another simple carbohydrate, advises the American Diabetes Association. Examples of fast-acting foods or beverages include 2 tablespoons of raisins, 4 ounces of fruit juice or regular soda, 1 tablespoon of sugar or honey, and 8 ounces of nonfat or 1 percent milk. Hard candies or glucose gel may also be used. Blood sugar should be retested after 15 minutes, and the procedure repeated until the blood sugar rises into normal range. Once blood sugar returns to normal, the individual should eat a light snack if the next planned meal is more than two hours away.
Symptoms of hypoglycemia are usually triggered when a person's blood sugar falls below 70 milligrams of glucose per deciliter of blood as measured on a glucometer, states the American Diabetes Association. Hypoglycemia may also be called insulin shock or may be referred to as an insulin reaction.
