Hypoglycemia is the medical term for low blood sugar. Reactive hypoglycemia, sometimes called postprandial hypoglycemia, happens when blood sugar drops after a meal — usually within four hours after eating. Symptoms of hypoglycemia may include: Shakiness. Dizziness or lightheadedness.
Diarrhea. Flushing. Dizziness, lightheadedness. Rapid heart rate. Late dumping syndrome starts 1 to 3 hours after you eat a high-sugar meal. It takes time for signs and symptoms to develop because after you eat your body releases large amounts of insulin to absorb the sugars entering your small intestine. The result is low blood sugar.
Causes. By Mayo Clinic Staff. Most of the time fatigue can be traced to one or more lifestyle issues, such as poor sleep habits or lack of exercise. Fatigue can be caused by a medicine or linked to depression. Sometimes fatigue is a symptom of an illness that needs treatment.
Tingling and numbness in the hands and feet. Although it's a less common symptom, tingling and a loss of sensation, called numbness, can happen in the hands and feet of people with diabetes. That's because too much blood sugar can affect the way nerves work. Burning pain in the arms, hands, legs and feet also may happen.
Blood sugar regulation. Most of the body's glucose comes from food. The hormone insulin lowers blood sugar (glucose) levels when blood sugar is too high. If you have type 1 or type 2 diabetes and need insulin to control your blood sugar, taking more insulin than you need can cause your blood sugar level to drop too low and result in hypoglycemia.
Fatigue. Irritability or anxiety. Difficulty concentrating. Dizziness or lightheadedness. Tingling or numbness of the lips, tongue or cheek. As hypoglycemia worsens, signs and symptoms can include: Confusion, unusual behavior or both, such as the inability to complete routine tasks. Loss of coordination.

Certain medications, especially those that contain steroids. Skipping or not taking enough medication that lowers blood sugar. Taking medications incorrectly. Illness, infection, injury or surgery.
Later signs and symptoms. If hyperglycemia isn't treated, it can cause toxic acids, called ketones, to build up in the blood and urine. This condition is called ketoacidosis. Symptoms include: Fruity-smelling breath. Dry mouth. Abdominal pain. Nausea and vomiting.
