Both women and men may have symptoms of polyuria, polydipsia, and lethargy when blood glucose is elevated, but they may also not have any abnormal symptoms. It is recommended to monitor blood glucose on a daily basis, and seek medical attention when abnormal blood glucose levels are detected. When blood glucose is elevated, different people react differently to blood glucose. Some patients may experience different degrees of thirst and excessive drinking, polyuria, increased nocturia, fatigue, and emaciation due to elevated blood glucose. Female patients may have urinary or gynecological inflammatory manifestations, such as perineal itching and abnormal vaginal secretions. However, there are also many patients, who do not have any clinical symptoms, and are only inadvertently detected when blood tests are taken or surgeries are performed. If the above clinical symptoms occur, you need to consult a doctor in time, take blood to check the blood sugar situation, do not self-medication or leave it alone.
