Some abnormal blood glucose manifests as high blood glucose or may manifest as hypoglycemia, with different blood glucose values showing different symptoms.
The main manifestation of hypoglycemia is sympathetic excitement, such as hunger, sweating, panic, weakness, nausea, vomiting, pallor, and cold hands. Severe symptoms may include central nervous system manifestations, such as coma, lethargy, confusion, mental disorders, and incontinence.
Symptoms of hyperglycemia are closely related to duration and value. A short period of hyperglycemia or a slightly higher than normal value does not necessarily result in significant symptoms. With longer-lasting hyperglycemia, symptoms of immune deficiency such as excessive drinking, overeating, polyuria, weight loss, fatigue, numbness and pins and needles in the hands and feet, and recurrent skin infections may occur. Severely ill diabetics may also experience blurred vision and ulceration of the extremities.
Usually pay attention to a reasonable diet and do not overexert yourself. If you have an abnormal blood glucose level, you should make timely life adjustments and take medications under medical supervision if necessary to prevent life-threatening exacerbations.
