My son who is 20 years old, 6 feet 3 inches tall, suddenly developed stomach problems and was unable to eat properly. After numerous medical tests were done, the doctors concluded that his stomach had become “HYPOTONIC”. His Barium X-rays showed image of a long, angulated, "fish-hook" stomach with a sagging greater curvature and decreased peristalsis. It has been 5 years now and the doctors still do not know what could have caused this condition. We tried almost all motility promoting drugs like Metaclopromide, Domperidone, Mosapride, Erythromycin, but none helped. Could you please suggest any medicine or exercise or anything which can help his stomach to regain its tone and shape? Thank you.
