Hello my friend Thanks for your question on HCM Here are some points i would like to say to you: 1. Eating habits,ne of the ways is to ingest it, so I always ask about carbonated beverages. The second way, however, is to swallow air, and this is very common. It may be by a learned behavior, because some people do this when they get nervous, so I ask, does it get worse when you have anxiety or stress? Second is the way that they eat. Do YOU eat rapidly, and do you slurp their food? Do you do things like sip through a straw frequently, because that gives to you a bolus of air every time they suck the liquid; actually take down a bolus of air as well. Then there are certain circumstances where people may not have good eating utensils. They may not have well-fitting dentures. That s a very common situation as well. If you are a smoker, you take a volume of air every time they inhale. If you are sucking on dietetic candies or really any hard candies or chewing gum, these may facilitate the repetitive swallowing that may not be natural, but in response to having that extra stimulation of liquid secretions accumulating in their mouth. So those are ways that you start to think about upper gass belching. 2.Dietary sweeteners 3.Legumes or beans are very classic for causing gas 4.Fiber and fiber supplements .A patient who is eating a lot of fiber may actually be precipitating a lot of this gas 1.So you should avoid chewing gum and candies that they suck on during the day. 2.Anti-gas agents. Medications that are potentially helpful here, include Beano, which is a product that helps digest stachyose and raffinose, is only really helpful in patients who [are ingesting] fiber that contains those sugars (beans, and to a lesser degree vegetables) 3.For rectal gas, the addition of charcoal is helpful in some people, taking it before and after a meal. Hope this information is helpful Best regrds
