Hypoglycemia refers to a condition where the concentration of glucose in the bloodstream is too low, leading to insufficient energy supply in the body. This can excite the sympathetic nervous system or disrupt central nervous system functions, resulting in a range of clinical syndromes. Hypoglycemia is relatively common in our daily lives. Its symptoms often include palpitations, dizziness, trembling limbs, apathy, abnormal behavior, and in severe cases, even coma or sudden death. Therefore, timely diagnosis and treatment of hypoglycemia are very important.
