Thanks for contacting healthcare magic. You have problem of gas and foul odour that may be because of intestinal infection. Do a stool examination test is helpful to check a infection. More fatty food consuption and some food allergy also cause bloting stomach. Irritable bowel syndrome may cause abdominal bloting problem and other problem. Intestinal condition like celiac disease may cause this type of symptoms. Consent a gastroenterologist for further diagnosis. Abdominal ultra sonography can done if needed. Drink more water per day. Avoid gaseous foods like cabbage, cauliflower, carbonated drinks etc... Take lemon water and Tutsi leaves helpful in digestion. Use garlic and ginger in diet for proper digestion. Use fruits like peach, kiwi and avocado etc.. I hope my guidance helpful to you.. Take care. Thank you.
