1. Effective for type 2 diabetes: Metformin is a commonly prescribed medication for the treatment of type 2 diabetes. It helps lower blood glucose levels by improving insulin sensitivity, reducing glucose production in the liver, and increasing glucose uptake in muscles.
2. Weight management: Metformin has been shown to help with weight management in individuals with type 2 diabetes. It can lead to modest weight loss, which may be beneficial for overweight or obese individuals who are at risk for or have type 2 diabetes.

Cons of Metformin 1000mg:

1. Gastrointestinal side effects: Metformin can cause gastrointestinal side effects in some individuals, such as nausea, diarrhea, stomach upset, or abdominal pain. These side effects are usually mild and temporary, but they can be bothersome for some people.
2. Risk of lactic acidosis: Although rare, metformin has been associated with a potential risk of lactic acidosis, a serious condition characterized by the buildup of lactic acid in the bloodstream. This risk is higher in individuals with kidney or liver impairment, severe infection, or other conditions that can affect metabolism. It is important to follow the recommended dosing and monitoring guidelines, and discuss any concerns with a healthcare provider.
