Hypoglycemia is a condition in which the blood sugar (glucose) level falls too low for bodily functions to continue. Glucose is the bodys main energy source, and when its level drops below the standard range, it can cause several symptoms, including shakiness, sweating, headache, hunger, and irregular or fast heartbeat. Hypoglycemia can occur in people with diabetes who take too much insulin or other diabetes medications, skip meals, or exercise more than usual. It can also occur in people without diabetes due to certain medications, a rare tumor of the pancreas, or other underlying conditions. Severe hypoglycemia can cause confusion, slurred speech, blurry vision, loss of coordination, and even coma or death. To prevent hypoglycemia, it is important to practice good diabetes management, monitor blood glucose levels regularly, and learn to detect hypoglycemia symptoms so that it can be treated early. If you experience low blood sugar, you should consume sugar or carbohydrates immediately to raise your blood sugar level. If you have diabetes and experience severe hypoglycemia, you may need emergency glucagon and/or medical intervention. If you dont have diabetes and experience low blood sugar, you should talk to your healthcare provider to determine the underlying cause.
