Hello Naren, Thank you for posting on HCM Actually flatulence or farting is the process of emission of gas from the anus. The gas is formed by breakdown of food (by chemical substance such as enzymes and acids) in the stomach and intestines. Everyone fats from 5-20 times a day. But now the frequency and odor depends on each individual. On its own it is not a serious life threatening condition but can be embarrassing as probably is your own case. The causes vary from person to person. Common causes include swallowed air, food and beverages, medical conditions such as bowel obstruction and crohn s diseases. Thyroid insufficiency or hypothyroidism is a situation in which the thyroid gland does not produce sufficient thyroid hormones and thus can lead to metabolic disorders which can subsequently affect the bowels and hence produce symptoms like farting ( which is purely as a secondary condition to constipation and hard stools). Overactive thyroid or hyperthyroidism in the other hand can also lead to farting which is also secondary to increased bowel movements. You may be able to prevent gas by changing your eating and drinking habits. Occasionally gas is a symptom of a medical condition that requires treatment. Examples of gas-producing foods are: - Vegetables such as artichokes, asparagus, broccoli, brussels sprouts, cabbage, cauliflower, cucumbers, green peppers, onions, peas, radishes, and raw potatoes. - Beans and other legumes***. - Fruits such as apricots, bananas, melons, peaches, pears, prunes, and raw apples. - Wheat and wheat bran. - Eggs. - Carbonated drinks, fruit drinks, beer, and red wine*. - Fried and fatty foods**. - Sugar and sugar substitutes. - Milk and other dairy products, especially in people who have trouble digesting lactose, the main sugar found in milk. - Packaged foods that contain lactose, such as breads, cereal, and salad dressing. You can try by doing food eating trials for each of the above to identify which of the food types is responsible for your smelling fart, then probably stop taking it. Dietary supplements such as Beano may help to prevent gas. Some people get relief from gas from products containing simethicone, a medicine that dissolves gas bubbles. You can also try controlling the emissions ( requires some training) and only do it when you are alone. Also take note that excessive yeast cells in the intestines can also contribute to this as they facilitate fermentation of food which also implies production of excess gas. So after a stool test (if positive for excess yeast), you might require antifungal medication. A gastroenterologist can be of help if the problem persist despite doing all of the above. Hope this helps and wish you the best
