Normally, blood glucose levels are tightly controlled by insulin, a hormone produced by the pancreas. Insulin lowers the blood glucose level. When the blood glucose elevates (for example, after eating food), insulin is released from the pancreas. This release of insulin promotes the uptake of glucose into body cells. In patients with diabetes, the absence of insufficient production of or lack of response to insulin causes hyperglycemia. Diabetes is a chronic medical condition, meaning that although it can be controlled, it lasts a lifetime.
For people with either type of diabetes, exercise can lower the chance of having a heart attack or stroke and can improve circulation. It may offer stress relief, as well. People with type 2 diabetes who need to lose weight can benefit from moderate exercise. Most people with diabetes are encouraged to get at least 150 minutes each week of moderate-intensity aerobic physical activity, like walking. Strength training is often recommended at least twice a week. Talk to your doctor about what type of exercise is right for you.
Note that these medications used to treat type 2 diabetes are typically not used in pregnant or breastfeeding women. At present the only recommended way of controlling diabetes in women who are pregnant or breastfeeding is by diet, exercise, and insulin therapy. You should speak with your health-care professional if you are taking these medications, are considering becoming pregnant, or if you have become pregnant while taking these medications.
