Im 21 yrs old and I've had this problem since I was a little girl. At times I am unable to eat. The smell and or the sight of food will make me gag. This can happen even when I am super hungry! I have been diagnosed with GERD and Im on medication for it. My docs and I thought the GERD was causing my food problem but that's not the case because Im still suffering. It doesn't happen everyday but it's still very frustrating when it does happen. I love food and Im tired. Can someone help?
