My son aged 18 years does not have good digestive system. As a kid he used to have constipation and would pass stools after two or three days. Now he complains of having abdominal gasses and for which he is very much disturbed and find it hard to concentrate on his studies. Though he is somewhat responsible himself due to his eating habits. He likes parathas, samosas and other packed food items. He is lazy as well. He has no regular sleep timings. He dislikes jogging, walking and playing games. How can he be get rid of these ailments? Thanks.
