For those with type 2 diabetes, keeping blood sugar levels under control can seem like walking a tightrope. But that delicate balancing act may benefit more than just blood sugar.

For those with diabetes, metformin not only helps to control blood sugar, but it may also boost heart health. The cardiovascular benefit, however, may not extend to those without diabetes.

The most widely prescribed medication for diabetes, metformin, also has heart health benefits for diabetes patients. For those without diabetes, however, its effects on the heart may be limited.

For those with prediabetes, blood sugar levels are high but not high enough to be diabetes. If patients don’t take action, however, they risk getting not only diabetes but heart disease as well.

Diabetes patients have to keep a watchful eye on their blood sugar level. If it dips extremely low, they can run the risk of developing a host of health issues, including heart disease.
