chronic abdominal distention with digestive symptoms that cause forceful belching, excessive gas, and sometimes a sense of sulfer tasting gas from stomach. H-Pylori, giardia and fecal matter tests all negative. Have started with pitting edema now, primarly in ankle/foot area. Body seems to retain water despite trying a diuretic. The more water I drink the more weight I gain. Using probiotics sporadically. Have pretty much ruled out dairy and wheat intolerances. Digestive issues seem to change from day to next, eating the same food. RX list extensive, (includes Remeron, Buspar, and recently added Lipitor). 20 lb. weight gain. No weight loss with reduced intake of fat/sugar, and increased activities within last month. Gained 3 lbs. when using the diuretic from drinking increased water. Thanks for any insite.
