My 63 yr old (4ft, 11 in) mother- very slim build- usually 80 lbs at best, now weighs 73 lbs. She has had for years - a heart racing feeling in her stomach. Many tests, no answers. Now, she has a backing-up feeling in her throat and nose, although nothing comes up. It makes her feel as if she can't breathe. She has also been feeling faint/dizzy/foggy headed. Her stomach spasms (not the same as the heart-racing) and when she feels this way- she feels panicky, and can't breathe. She does have an esophagus hernia. Says she feels "odd" right before a BM, which changes from reg. to diarrhea.
