Talk to Gastroenterologist on Stomach Gas

From 1 week I have a issue of gas at night time. When I go to bed I feel gas in my stomach and it expels through farthing all night . It don't creat any problem in digestion or excretion but I want to get rid of it. Due to pandemic I spent my all time at home and take online classes so my physical activity is much reduced which could also be a reason. Suggest me medicine.
