Take a short walk after eating. Do not sit and watch television after eating. Even just walking like a vagabond for 10 minutes will make your stomach airless. Do not lie down at night with pressure on the stomach or tilted to the right. It will digest food well. There will be no gas in the stomach. Change the diet: Some people have benefited from eating brown rice and barley soup. Papaya and pineapple contain digestive enzymes. In this case, papaya and pineapple are very useful.
