Diabetic patients often get dizzy for various reasons as follows: 1. Hypoglycemic reaction: Patients who apply sulfonylureas as well as insulin often get dizzy, and insulin and sulfonylureas directly lower blood sugar related to lowering blood sugar to a hypoglycemic state, resulting in dizziness, panic, hand trembling, sweating, and timely monitoring of peripheral blood sugar, which can be corrected by eating food or sugar water if it is hypoglycemia; 2. Blood sugar is too high. In case of infection, trauma or discontinuation of insulin, discontinuation of hypoglycemic drugs, blood sugar increases sharply in a short period of time, leading to diabetic ketoacidosis and hypertonic, hyperglycemic state, the patient will also have dizziness symptoms, accompanied by nausea, vomiting, confusion, and even coma, to monitor blood sugar, and promptly sent to the hospital for treatment; 3, diabetic patients are prone to combined hypertension: blood pressure is too high or too low, or Dizziness can occur when the blood pressure fluctuates a lot. If the blood pressure is too high, increase the antihypertensive drugs, if the blood pressure is too low, reduce the antihypertensive drugs, or consult an endocrinologist. 4, diabetic patients combined with atherosclerosis: leading to cerebrovascular disease, such as ischemic stroke, that is, cerebral infarction, but also hemorrhagic stroke, that is, cerebral hemorrhage, as well as angina pectoris, myocardial infarction, will occur dizziness, to be promptly to the hospital for treatment and an electrocardiogram as well as a CT examination to further clarify the diagnosis. Therefore, dizziness in diabetic patients is often seen in hypoglycemic and hyperglycemic states, as well as in combined hypertensive blood pressure fluctuations and cardiovascular diseases, which can easily lead to dizziness.
