Women with hypoglycemia will experience panic, sweating, pallor, etc. in mild cases, and in severe cases, they will experience impaired consciousness, coma, and other harmful symptoms. For non-diabetes, blood glucose below 2.8mmol/L is considered hypoglycemia; for diabetes, blood glucose below 3.9mmol/L is considered hypoglycemia. The effects of hypoglycemia on the body are dominated by the nervous system, especially the brain and the sympathetic nervous system. The energy needed by brain cells comes almost entirely from blood sugar. While the brain can utilize ketone bodies when blood glucose is lowered, ketone bodies take some time to form and do not resist the damage to the brain caused by the lack of energy during acute hypoglycemia. When hypoglycemia occurs for a short period of time, it causes sympathetic over-excitation and symptoms such as pallor, palpitations, sweating, nausea and vomiting. The manifestations of the central nervous system during hypoglycemia can be mild or severe, ranging from mild impairment of mental activity to convulsions, coma and even death. Therefore, women should not ignore hypoglycemia because frequent episodes and prolonged hypoglycemia may cause brain damage. Therefore, women are advised to always carry a candy bar on them if they have symptoms of hypoglycemia to avoid fainting symptoms. In case of any discomfort, it is recommended to seek medical attention to find out the cause of the problem.
