Metformin is a medication commonly used to treat prediabetes and type 2 diabetes. It helps lower blood sugar levels and improves insulin sensitivity. Additionally, metformin may provide several health benefits, including reducing the risk of heart disease, stroke, and certain types of cancer.
Dr. Emily Carter, a leading endocrinologist, believes that metformin is a valuable medication for managing type 2 diabetes and reducing the risk of associated complications. She says, “Metformin helps lower blood sugar levels and improves insulin sensitivity, which are crucial for managing diabetes. Additionally, studies have shown that metformin may reduce the risk of heart disease, stroke, and certain types of cancer.”
Dr. Carter explains that metformin works by increasing the body’s sensitivity to insulin, a hormone that helps glucose enter cells for energy. When the body is more sensitive to insulin, it can use glucose more effectively, leading to lower blood sugar levels. Metformin also helps reduce the production of glucose by the liver, further contributing to lower blood sugar levels.
Overall, Dr. Carter believes that metformin is a safe and effective medication for managing type 2 diabetes and reducing the risk of associated complications. She recommends that patients with type 2 diabetes talk to their doctor about whether metformin is right for them.
