Can taking metformin effectively control blood sugar levels?

Metformin is commonly available in tablet form. In most cases, taking metformin can effectively control blood glucose levels. However, its effectiveness may vary from person to person. If any abnormalities occur, prompt medical attention is recommended. Detailed analysis is as follows:

Metformin primarily controls blood glucose levels by reducing hepatic glucose production, increasing glucose uptake in muscle and fat tissues, and improving insulin resistance. For patients with type 2 diabetes, metformin can help lower both fasting and postprandial blood glucose levels, thereby reducing glycated hemoglobin (HbA1c) levels.

However, it should be noted that patients with type 1 diabetes have severely impaired pancreatic function and are unable to secrete sufficient insulin to maintain stable blood glucose levels. Therefore, metformin cannot replace insulin therapy in these patients. Additionally, metformin should be used with caution in patients with impaired liver or kidney function. Moreover, if a patient's blood glucose level is extremely high, metformin alone may not adequately control blood glucose levels, and combination therapy with other antidiabetic medications or insulin may be necessary.

Patients taking metformin should closely monitor their blood glucose levels, perform regular blood glucose testing, and adjust medication dosages according to medical advice. At the same time, attention should be given to dietary control and appropriate physical activity to manage blood glucose levels.
