Hi Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concern... As you have symptoms of severe acidity, less digestion, severe bloating after having protein diet you should be suffering from Irritable bowel disease, therefore your doctor has prescribed you Rifagut-400 Mg twice a day for two weeks. You should continue the medicine & follow this diet plan also. 1. Eliminate high-gas foods such items as carbonated beverages, vegetables such as cabbage, broccoli and cauliflower. 2 Avoid spicy & too much fried foods. 3. Some people are sensitive to types of carbohydrates containing fructose, or fructans called FODMAPs .They are found in wheat, rye, barley, onion, garlic, apples, apricots, avocados, blackberries, cherries,etc. In some patient avoiding these food shows improvement in symptoms. In some people symptoms may become relieved if they avoid milk & milk products such condition is called lactose intolerance. 4.Taking fiber supplements, such as psyllium or methylcellulose, with fluids may help control constipation. 5. As you are having bloating after taking protein diet, avoid those things too. Refer to your physician Don t worry you would be fine Hoping your query is solved.
