Brief Answer:
due to absence of normal bile changes
Detailed Answer:
HI, thanks for using healthcare magic
The normal brown colour of stool is due to changes that occur to bile as it passes through the
liver and the rest of the gastrointestinal tract.
During bouts of
diarrhoea, because stool is passing out of the intestinal tract more quickly, the changes in the bile may not occur because it is unable to change as quickly as the stool is being produced.
This means that bile is unable to undergo the changes from green to brown, this causes the stool to have an abnormal appearance.
Though you normally have instances of diarrhoea, it is possible that the present symptoms may be related to viral or
bacterial gastroenteritis, especially since you are also feeling nauseous.
Normally , the illness is self limited lasting only a few days, especially in an adult.
The
pepto bismol would help relieve your symptoms and the gatorade would help to replace the fluids and electrolytes you are using.
Fluid and electrolyte replacement are the most important treatment aspects of gastroenteritis.
IN terms of eating, you may want to try yogurts (1 to 2 a day) and very small amounts of dry foods. Yogurts contain probiotics and these have been shown to be helpful with these types of gastrointestinal complaints. Probiotics can be used in foods such as yogurt or purchased on their own.
If even the small amounts of dry food worsen the
diarrhea, hold off on them for another 2 to 3 hours but still continue the fluids and probiotics.
I hope this helps, feel free to ask any other questions
