it started with abdominal discomfort (a little pain now and then) mingled with bouts of constipation - i have very little fibre in my diet.
more recently i started to feel full earlier than i usually would after a meal, and bloat and have to burp quite frequently. even more recently i noticed some mucus in my stool.

i've visited the gastroenterologist, but he insisted that a teenager of 15 will not suffer from anything worth worrying over. after three visits he gave nothing more than fibre shakes.
any opinions on this?
