You can buy Simethicone tablets, you take them as needed, when you feel bloated and it's chewable. Helps in reliefing the bloating by passing gas. Another alternative, you buy an antiacid syrup that has simethicone in it. That way, it can help slightly with both the heartburn and the bloating. Avoid legumes and pulses from your diet (shiro, misr, fool, beloke), fried foods like sambusa and chips can worsen the symptoms of bloating, also milk or any dairy product like ayib, also some leaves like corriander (ድምብላል). I know being not able to hold gas might be embarrasing, and the drugs I told you help in passing gas faster, but the most important thing is fixing your diet through mainly avoiding these foods, that's how u solve the root cause. Also, go for a checkup, most likely your diagnosis is IBS, if there's nothing really wrong ( blood work up/ ultra sound/ colonoscopy - if there's a disease to be diagnosed). Avoid and manage stress as much as possible, look up for some yoga exercises, it helped some people. Drink 2 glasses of cold water in the morning and chew on some ጠና ኣዳም it makes your farts less smelly.😁
