After timely and effective drug treatment, patients with high blood glucose can generally return to normal within 1 week, stabilizing it in the normal range, after which patients often need to take long-term medication. Patients with high blood glucose should seek medical attention as soon as possible, and use appropriate hypoglycemic drugs under the guidance of a doctor. Blood glucose can usually be lowered very quickly, but it is easily affected by diet and needs to be controlled for a long time. People with elevated blood glucose tend to have poor control at first, with large fluctuations in blood glucose levels. Generally, blood glucose can be stabilized within the normal range after 1 week of adherence to medication. Patients should note that, in addition to diet, drug type and dosage can affect their own glucose-lowering effect, for example, patients taking a single glucose-lowering drug for a long time and drug resistance, resulting in prolonged return to normal blood glucose, this time the need to increase the dosage or change the glucose-lowering drug under the advice of the doctor in order to achieve a better lowering of glucose effect. Patients should learn more about medical knowledge related to blood glucose, and control their blood glucose by combining dietary control and exercise after taking the medication to stabilize their blood glucose within a safe range for a long period of time. If patients experience symptoms such as dizziness, nausea, fatigue, or excessive drinking, eating, or urinating, they should seek immediate medical treatment.
