It is also important that you do not smoke. People with diabetes tend to have circulation problems. Smoking constricts blood vessels, which makes circulation problems worse.
It also contributes to heart disease, and people with diabetes are already more likely to develop heart disease without the added problems caused by smoking. If you are not worried about your heart or lungs, remember that circulation problems affect your whole body. Poor circulation to the feet can lead to very serious problems, including amputations. For men poor circulation can contribute to erection problems as well.
Before you take any medicine—prescription or nonprescription drugs, herbal remedies, or supplements—speak with your health care provider. Some nonprescription drugs contain ingredients that can affect blood sugar, making it more difficult to control your diabetes.
Some vitamins, minerals, and natural products can also affect blood sugar. Read all product labels very carefully and pay attention to the warnings. When buying nonprescription remedies, look for sugar-free and alcohol-free products. If you are not sure about something, ask your health care provider.
If you see more than one health care provider—for example, a family physician plus a specialist—make sure that all your health care providers are aware of your diabetes and your most recent blood sugar results. Some medicines used for other conditions should not be prescribed for a person with diabetes.
