I am never hungry & when u force my self to eat i only take a bit or two & appetite just go away ?

Many causes. C ur MD: Can be due to unrecognized empty calories, including alcohol, chewing gum, etc. May be due to depression, meds, systemic disease (long list of possibilities), can be due to organic problems with stomach, pancreas, liver, etc. Symptoms like anorexia (loss of appetite), situphobia (fear of eating-usually because of inducing symptoms), and early satiety (get full fast) should be evaluated.
