Hi,my name is dr.Dorina Gurabardhi.Welcome to HCM! I undestand your concern.Alcohol irritates your digestive system. Drinking ,even a little ,makes your stomach produce more acid than usual, which can in turn cause gastritis(the inflammation of the stomach lining). This triggers stomach pain, vomiting, diarrhoea and, in heavy drinkers, even bleeding.Some advices that I can give are: -Do not mix drinks: Mixing drinks makes it more difficult for you to keep track of what you’re consuming, so it’s likely you’ll drink more alcohol than you would just sticking to one type of drink. The more you drink, the more likely you are to be physically sick and feel hungover afterwards. -Do not use painkillers: While they’ll make a pounding head feel better, painkillers can have the opposite effect on your stomach. “Painkillers, such as aspirin, can further damage the stomach. Paracetamol is an effective pain killer. But rather than taking pills to settle an upset stomach after drinking, try an antacid, or a cup of mint tea instead.” -Eat food before drinking: Eating something, preferably carbohydrate-rich food, before you start drinking may help slow the rate your body absorbs the alcohol. Drinking water or soft drinks throughout the night will also slow your drinking down. Hope my answer helped you,thanks!
