People sometimes feel an unpleasant smell coming from their mouth. Flatulency is the main reason for such odor to appear. It is caused by the bacteria located in the big gut. It provokes a tiny number of gases with sulfur, which is spread over the organism. When there is a huge accumulation of gases, patients experience a strong desire to bloat. It is followed by the abdominal pain. Doctors recommend to pass gas or shake the bowel in some way to get rid of this feeling. Releasing gases is a natural thing, but patients with stomach bloating cannot always control this process.
