Hi Dear, Understanding your concern. As per your query you have symptoms of recurrent diarrhea and constipation which seems to be due to infection by H. Pylori leading to gastroenteritis. It could be due to electrolyte imbalance in body. Need not to worry at all. I would suggest you to ensure you are taking adequate hydration, oral intake and replenishing water to avoid salt losses. Visit gastroenterologist once and get it examined. You should go for complete examination and start treatment after that. You should avoid intake of outside food, such as hot, sharp and excessive spicy food and avoid intake of cold carbonated beverages. Don t panic. You should take oral rehydration solution. Hope your concern has been resolved. Best Wishes, Dr. Harry Maheshwari
