Hypoglycemia

is a condition that requires high attention. When it is low, the brain is significantly affected. Because the brain is almost entirely dependent on glucose for energy, hypoglycemia can cause brain dysfunction, dizziness, blurred vision, unconsciousness, and even coma, which can be life-threatening. Hypoglycemia can also cause heart problems. It can cause arrhythmia, myocardial ischemia, etc., increasing the risk of heart disease, especially for patients with underlying heart disease. In addition, hypoglycemia can affect other systems and organs of the body. For example, it can cause muscle weakness, poor body coordination, increase the probability of accidents such as falls; it can also cause digestive disorders, nausea, vomiting and other discomfort.
