What is Metformin

What Is Metformin and How Does It Work?

Metformin is prescribed for treating type 2 diabetes, as well as a polycystic ovarian syndrome (PCOS). It decreases the amount of sugar your liver produces, and your intestines absorb. It also helps make your body more sensitive to your insulin. By doing this, Metformin can help control blood sugar levels.

Metformin has also been shown to help people lose weight and treat diabetes. An obese adult without diabetes who took Metformin lost 5% of their body weight over six months.1 This is significant because even a tiny amount of weight loss can positively impact their health. For example, you can lower your blood pressure and cholesterol levels by losing 5% of your body weight.

Discuss Metformin with your doctor if you are overweight or obese and cannot lose weight through diet and exercise alone.

Is Metformin Effective for Weight Loss?

It is effective in promoting weight loss in obese non-diabetics. According to a study published in the Journal of Clinical Endocrinology & Metabolism, those who took Metformin lost an average of 5.8% of their body weight after 12 weeks compared with those who did not take the medication. Also, older participants with higher body mass indexes (BMI) and females were more likely to benefit from Metformin.

Metformin reduces the amount of glucose the liver produces and increases insulin sensitivity. Besides lowering blood sugar levels and reducing hunger, Metformin has also been shown to reduce inflammation associated with obesity and decrease fat cell production.

Can Metformin be used for weight loss?

Evidence suggests Metformin could lead to weight loss in obese non-diabetic adults, but this has yet to be conclusively proven. A systematic review of 11 studies conducted in 2012 found that, compared to a placebo, Metformin induced an average 2.7 kg decrease in body weight and was more effective in those with a BMI ≥ 30 kg/m2. The same review noted that the evidence supporting these conclusions was of low quality, and further research must be done to confirm these results.

Additionally, a 2013 study found that Metformin may reduce abdominal fat mass in obese adults, regardless of body weight changes. This suggests that Metformin could be particularly useful for people seeking to lose weight in specific places.

Overall, there is some promising evidence that Metformin may be effective for weight loss in obese adults, but more research is needed to draw firm conclusions. It is crucial to talk to your doctor first if you want to use Metformin for weight loss.

How Does Metformin Cause Weight Loss?

Various mechanisms have been proposed to explain how Metformin causes weight loss. According to one theory, Metformin reduces appetite and increases fat burning by improving insulin sensitivity.

Additionally, the metformin group saw improvements in blood sugar, cholesterol, and blood pressure, so Metformin can help you lose weight and improve your health overall!

Can people take Metformin without diabetes?

Metformin can help people with weight loss without diabetes. It is often prescribed to people with PCOS (polycystic ovary syndrome) who do not have diabetes but gain weight.
