7. You lose weight
If you suddenly lose weight without trying to, this can point to a couple of different things, one of which is diabetes. Insulin transports sugar from your blood to your cells and this provides energy. If you don’t have enough insulin, your body will need to burn something else: fat and muscles. This causes you to suddenly lose a lot of weight. If you have lost between 5 and 10 per cent of your body weight within six months, you’ll need to visit a doctor.
