Is it the normal kind of shit or the runny type?
If normal, type, it could be due to your increased intake of
dietary fibre and/or water, in which case is good as your body is
clensing out the garbage in your bowels.
But if runny type, it could be a case of food poisoning. Any
fever? They usually come together. If so, continue to drink lots of
fluids. This will prevent your body from suffering dehydration. You
can try taking Po Chai pills, available at most Chinese medicine
shops. Even Guardian sells them!
Charcoal pills are supposed to help stop the runs…......
See a doctor lah.
