But before starting your exercise schedule you must keep three things in mind: Firstly, because any increase in the physical activity can lower your blood sugar level, you need to plan your meals and your medical dosage. But do not forget to consult your doctor in this regard. Exercising without the consultation of your doctor is not only dangerous but can be fatal too. Secondly, have regular medical checkups. This will keep you informed about your health status and will also help your doctor in predicting your progress properly. And at last... check your blood sugar level before and after exercising. This is very important as you will get a firsthand knowledge about your sugar level and you'll also come face to face with the benefits or any side-effects of the exercise that you are doing. Mostly you'll reap the benefits only; though sometimes over-exercising can cause problems. The different exercises that I would recommend are walking, jogging, cycling, swimming, rowing, aerobics etc. Aerobic exercises are the best as they strengthen the heart and the lungs. Do the exercise that suits you, but begin slowly. In the beginning spend 5-10 minutes daily. You can increase the intensity and duration of your exercise gradually. Sometimes, order to get healthy quickly, people follow very strict regime of exercise. I would advise you to never ever exercise beyond what your body allows, as over- exertion can result in dangerous consequences. So stay fit.
