Apart from consuming air while eating and drinking, what causes excessive gas production in stomach? I know gas is produced while digestion takes place. But is there any other way that gas is produced? I have been suffering from bloating issue for about 5 years. Should l worry about any organ damage in my stomach? But l never felt any kind of pain or burning sensation anywhere in my stomach all these years. I consulted with gastroenterologist and took two endoscopy in different years. The result came that my stomach was healthy. But why do l still get bloating problem?
