Hello, How old are you?? since when you re suffering from this symptoms. Until examination is done it is difficult to say what it is. Probably you may be suffering from acute gastritis or irritable bowel syndrome or food intolerance or malabsorption syndromes or inflammatory bowel problems etc. Until examination is done it is difficult to say what it is. Avoid spicy food and alcohol avoid smoking and caffeine drinks. Avoid lactose and gluten contain food. Use tablet Normaxin. Linaclotide may useful in constipation patients.
