Also not a doctor, but from what I've read for some people it could lead to starvation and death. Basically when you are fasting, your body starts to eat your fat instead, so if you have some underlying disease, or if you are extremely lean, or e.g. a high-maintenance sports person, you are probably at very serious risk. That said, 10 days seems a bit short for death, but yeah if you are in one of those 3 groups (high sports, extreme low fat, or with some disease) I would not take fasting lightly.
