Dear Mr Upadhyay,
The symptoms that you mention could be suggestive of hepatic(liver
) involvement, as there is loss of appetite , bowels are not clear and weight loss
. But is the weight loss drastic or over a period of time?
You need to visit your family physician or a gastro-enterologist who would advise you certain blood tests(Liver function tests) and ultra sonography
to evaluate the cause and decide the line of treatment.
