embarassing problem

[henfox]

i have been passing foul-smelling gas and stools for a few months now. i eat plenty of fruit and vegetables, exercise plenty, drink plenty of water and take multi-vitamins, glucosamine and cod liver oil daily. i am 25 years old and am not a vegetarian or vegan. what is likely to be the cause of this problem?

[henfox]

i do quite a lot of exercise and also have a physical job so i'm trying to look after my joints. do you think the supplements could be causing it?

Any special reason (except for B12) to take multivitamins, glucosamine, and cod liver oil?

[henfox]

stools sink normally and look normal sometimes a bit messy. the smell is sort of like a sewer smell. i haven't taken any antibiotics at all for about a year.

Are stools whitish, greasy, sticky, and floating?
Were you taking any oral antibiotics at the time or in days/weeks before the smell appered?
Is smell like
- rotten eggs
- barnyard smell
- other?
