Glucose is the primary source of energy in body. Hypoglycemia is a condition which occurs when the blood sugar (glucose) level falls lower than normal. It can cause headaches, fatigue, clumsiness, difficulty in speaking, disorientation, a racing heart, sweating, shakiness, nervousness, hunger, loss of consciousness, seizures, or death. Medications used to treat diabetes, such as insulin, sulfonylureas, and biguanides, are the most common cause of hypoglycemia. People with diabetes who have eaten less than usual, exercised recently, or have consumed alcohol are at higher risk for this medical condition. Medical problems like sepsis, kidney failure, liver disease, hormone insufficiency, malignancies such as insulinomas or non-B cell tumours, inborn metabolic abnormalities, numerous drugs, and alcohol can all lead to hypoglycemia. This book presents new insights into the causes and consequences of hypoglycemia. It consists of contributions made by international experts. Those in search of information to further their knowledge will be greatly assisted by this book.
