I used to have the same problems when I was young. He is likely to have gallstones, both in the liver and gallbladder, like so many kids today. The choice of foods among young people is mostly responsible for that. Fast foods, snacks, junk foods, fizzy drinks, etc. act like poison in the body and congeal bile. There are children today that already have thousands of stones in their liver and GB. He can be helped by doing the liver cleanses as explained in The Amazing Liver Cleanse, www.1stbooks.com. It is essential for his that he makes alterations to his diet and lifestyle (eating a Pitta -balancing diet, etc. see my book The Key to Health and Rejuvenation, also www.1stbooks.com).
With best wishes,
