Whether it is too much for a diabetic patient to take more than 50 units of insulin in 1 day, this is analyzed on a case-by-case basis. First of all, for type 1 diabetic patients, they must rely on insulin to keep their blood sugar stable. As long as patients strictly control their diet and meet the standard with appropriate exercise, the insulin dose is determined by various aspects such as body weight, sensitivity to insulin, and the presence of stress at the time. In cases where blood glucose is on target and there is no hypoglycemia, the dose of insulin used in heavier patients may be higher compared to those who are lighter in weight, and some patients do exceed 50 units. However, generally speaking, with the emergence of new glucose-lowering drugs, if a patient uses more than 48 units of insulin a day, it is recommended to reduce the insulin dosage with some insulin-sensitizing drugs. Avoid hyperinsulinemia due to excessive insulin dosage. Especially for obese diabetic patients, before using insulin, it is important to see if medications to improve insulin resistance are applied to reduce insulin dosage. If necessary, newer glucose-lowering drugs, such as GLP-1 agonists and DPP-4 inhibitors, can be used to reduce insulin dosage. Avoid excessive insulin dosage, weight gain and a snowball-like vicious cycle that leads to hyperinsulinemia, which can cause a series of complications.
