Many benefits of Metformin aside diabetes
For decades we’ve known that metformin does more than just help lower blood sugar in people with diabetes.
It also offers them cardiovascular benefits, including lower rates of death due to cardiovascular disease. And it sometimes helps people with diabetes lose excess weight.
Metformin may also have health benefits for people who don’t have diabetes. Doctors have long prescribed it off-label — that is, to treat conditions outside its approved use, including:
Prediabetes. People with prediabetes have elevated blood sugar that isn’t yet high enough to qualify as diabetes. Metformin may delay the onset of diabetes or even prevent it among people with prediabetes.
Gestational diabetes. Pregnant women may develop elevated blood sugar that returns to normal after delivery. Metformin can help control blood sugar during pregnancy in such women.
Polycystic ovary syndrome (PCOS). This disorder tends to affect young women whose ovaries develop multiple cysts. Menstrual irregularities and fertility problems are common. Although the results of clinical studies are mixed, metformin has been prescribed for years for women with PCOS to help with menstrual regulation, fertility, and elevated blood sugar.
Weight gain from antipsychotic medicines. Antipsychotics are powerful medications prescribed for psychiatric diseases such as schizophrenia. One common side effect is significant weight gain. Metformin may lessen weight gain among some people taking these drugs.
In addition, researchers are investigating the potential of metformin to
Lower the risk of cancer in persons with type 2 diabetes. These include cancers of the breast, colon, and prostate.
Lower risks for dementia and stroke. Some studies have noted less cognitive decline and a lower rate of dementia, as well as a lower rate of stroke, among people with diabetes taking metformin compared with those who were not taking it.
Slow aging, prevent age-related disease, and increase lifespan. Preliminary studies suggest that metformin may actually slow aging and increase life expectancy by improving the body’s responsiveness to insulin, antioxidant effects, and improving blood vessel health.
