Metformin is a widely used medication primarily prescribed to manage type 2 diabetes. It helps lower blood sugar levels by improving how your body responds to insulin and reducing the amount of sugar your liver produces. This action decreases your blood glucose, helping you maintain healthier sugar levels. Many doctors also consider it a first-line treatment for type 2 diabetes due to its effectiveness and generally well-tolerated side effect profile.
How Metformin Works
Metformin primarily works by increasing your body’s sensitivity to insulin. Insulin is a hormone that helps glucose enter your cells for energy. Metformin helps your cells use available insulin more efficiently, leading to better glucose uptake. Additionally, it reduces glucose production by your liver, further contributing to lower blood sugar levels. This dual mechanism of action makes metformin highly effective in controlling blood sugar.
Common Side Effects
While generally safe, some people experience mild side effects, including nausea, diarrhea, and stomach upset, particularly at the start of treatment. These usually diminish as your body adjusts to the medication. More serious side effects are rare but include lactic acidosis (a buildup of lactic acid in the blood), which requires immediate medical attention. Your doctor will discuss potential risks and benefits before prescribing metformin, tailoring dosage to your individual needs and health status.
