Respected user, hi I evaluated your query thoroughly.
* In
Hepatitis A - inflammation and swelling of the
liver and is most often
caused by a viral infection.
* In Hepatitis stool is pale rather than brown , because bile is not being
made or reduction in bile production or there is blockage between the
liver and the bile ducts ;
diarrhea correlates with the same.
- dark stools require additional examination in form of Proctoscopy & stool
microscopy .
* SGPT levels remain elevated for some long time period in many cases.
Hope this clears your doubts .
Welcome for any further assistance.
