Hypoglycemia is a sudden drop in blood sugar levels below 70 mg/dl. It occurs often in people with diabetes. Insufficient nutrition and increased physical activity can lead to hypoglycemia. The condition affects the gastrointestinal, nervous and cardiovascular systems, and people with post-exercise hypoglycemia may exhibit a range of symptoms. Anyone experiencing post-exercise hypoglycemia should consume some form of sugar, such as candy, juice or glucose tablets.
Neurological Symptoms
The brain needs sugar to function and, for this reason, hypoglycemia affects the nervous system more than any other part of the body, according to MedlinePlus. Initially, you may experience confusion and irritability, and your behavior may change. If blood sugar levels continue to drop, you may begin trembling and experience muscular weakness or a headache. You also may suffer from dizziness and cold sweats, which could lead to falling or fainting. You may feel anxious or fatigued. Restoring blood sugar levels to normal by consuming glucose or sugar-based foods should reverse or prevent all symptoms. If you experience visual disturbances, such as blurred vision, experience a seizure or loss of consciousness, seek immediate medical attention.
Gastrointestinal Symptoms
A post-exercise hypoglycemic attack may begin with hunger as the brain signals the body that it needs more fuel to function. If blood sugar levels continue to drop, you may experience nausea, abdominal cramping and even diarrhea. As with the nervous system, restoring blood sugar levels to normal should reverse or prevent these symptoms. Drink plenty of fluids to stay properly hydrated. Seek immediate medical attention if you begin vomiting or feel malaise after exercise.
Cardiovascular Symptoms
Hypoglycemia can cause heart palpitations and a pounding sensation in your chest and temples. You may also experience difficulty breathing or catching your breath. Raising your blood sugar levels should relieve these symptoms. If you experience chest pain, especially pain radiating down and across your left side, or if your heart rate does not return to normal within a few minutes, seek immediate medical attention. Additionally, if your hypoglycemia symptoms become more severe, even after you consume sugar-rich foods, seek immediate medical attention.
