My Dad has the opposite problem. As some of you are aware, Dad is in hospital waiting for open heart surgery. Well he is suffering bouts of heaving at the thought of food and just can’t eat anything. Just mentioning food makes him heave. The doctor says there is no physical reason why this should be happening, and I feel it is a psychological problem. He is due to come home while he waits for the surgery but am very worried about him not eating. Maybe CBT could be the answer.
