Brief Answer: Can be Food intolerance or bacterial infection Detailed Answer: Hi there, Thanks for your query. Firstly, in order to PINPOINT the exact cause of generalized itching; give you a SOUND professional advice; and, TRUE VALUE FOR YOUR MONEY, I request you to kindly provide additional information as follows :- # Nature/symptoms of his stomach problems at present, such as, episodic diarrhea, bloating, acidity, abdominal discomfort, pain in the center of the chest; persisting constipation etc... # Present medications (with doses) for his mental health problems; any other medications. Some drugs tend to aggravate abdominal problems. # Any food which has identified with aggravation of abdominal problems. # Whether mental problems are under complete control on medications. This notwithstanding, from the information available, the possible causes of abdominal problems are :- (a) Food allergies/intolerance, such as Lactose intolerance (milk/milk products); Gluten intolerance (intolerance/allergy to wheat, barley, rye and their products). This possibility is strong in view of the onset of symptoms in early childhood. (b) A bacterial infection (by H.pylori) of the stomach and intestine (depending on the nature of stomach problems) Further, PS is a physical stricture (narrowing) of the stomach valve and, hence DO NOT relax under anaesthesia. Please appreciate that INPUT OF AS MUCH INFORMATION AS POSSIBLE, will be invaluable for me to reach to the ROOT cause of the stomach problems and, GUIDE you the further course of action. Hope I have addressed to your concerns to your complete satisfaction and you find my response helpful and informative. I will be happy to answer further queries, if any. Awaiting your further feedback, Fond regards and have a nice day, Dr. Rakesh Karanwal
