I have a small hiatal hernia and acid. I do not have heartburn, food stuck in my throat or coughing. All my tests, except for the hernia, came back negative. It has been over 6 weeks now and I ve lost 25 pounds. I don t drink, don t smoke and cannot eat much except Ensure and crackers which some times gets me sick. My upper stomach hurts, I get headaches and feel dizzy. I cannot seem to eat over 800 calories a day. I am 54 years old, 5 6 and currently 170 pounds. Thank you.
