I am a 67 year old female. I have always had a feeling of almost constant hunger. When I was younger it was not a problem and I did not experience any unusual weight gain until after menopause and the usual age related issues. I can remember my father complaining to my mother about it. I was fortunate enough to grow up eating enough food, lots of vegetables, fruits and meat. I was never undernourished. My son also experiences this. Are there any (I think obvious) hereditary conditions that would explain this and is there anything that can be done to control it? Diet or vitamins, etc.?
