Can gastritis cause difficulty in weight loss? been eating low carb, counting calories, lots of exercise, no weight loss! lots of gas, bloating, cramps

Yes.: Gastritis can cause improper digestion with gas, bloating, and cramps. This indicates a problem with stomach acid, small intestine enzymes, gut bacteria or combination thereof. Carbohydrates may stay too long in stomach and/or proteins/fats may pass through too quickly resulting in fermentation or putrefaction. Use enzymes, betaine and acidophilus from professional sources for best results.
