When I'm hungry sometimes, although I have had food at regular intervals, I feel dizzy, very weak and i suddenly sweat and body becomes cold. When I have some food, I normal again. I had this issue for 4 years now. Suspected this can be diabetes and had few tests. Reports said I didn't have diabetes. Consulted so many doctors but I don't seem to find what this problem is and what's the cure. It doesn't happen everyday. But it happens very often twice a week and sometimes all the week. Could anyone help identify the issue, please? Thanks in advance.
