Blood sugar rises after meals, drops during activity, and keeping it in a healthy range is key to preventing diabetes and other health problems.
Type 1 diabetes always requires insulin therapy, while type 2 diabetes can sometimes be managed with diet and exercise, though many people also need medications. Insulin injections help people who don’t produce enough naturally. Other medications, like Metformin, are used to lower blood sugar in type 2 diabetes, and several other drug classes are available depending on individual needs. People with diabetes may also take statins or other cholesterol-lowering medications to reduce cardiovascular risk, but these do not directly control blood sugar.
