Hi, I had gone through your question and understand your concerns. I dont htink this is related to your PArkinson disease.In most cases our dietary choices could lead to excessive flatulence. Some foods that increase gas include: Beans, cabbage, broccoli, raisins, lentils, prunes, apples, foods high in fructose or sorbitol, such as fruit juices. These foods can take a long time to digest, leading to the unpleasant smell associated with flatulence. If your diet doesn’t contain a large amount of carbohydrates or sugars, and you don’t swallow excessive air, your excessive flatulence may be due to a medical condition. Potential conditions underlying flatulence range from temporary conditions to digestive problems such as inflammatory bowel diseases, gastroenteritis, diabetes or peptic ulcer. As remedies you should: Look at your diet. If it contains a large amount of carbohydrates that are difficult to digest, try to replace them. Carbohydrates that are easier to digest, such as potatoes, rice, and bananas, are good substitutes. Also try to eat around five to six small meals a day instead of three larger ones to help your digestive process. Chew properly to avoid doing anything that may increase the amount of air that you swallow. This includes making sure that you are chewing your food properly, and avoiding chewing gum or smoking. Also, drink some peppermint tea, chamomile tea and ginger. Wishing you good health.
