Hi. Thanks for your query. Noted the history of clay colored stool, took too much pepto a week ago, there is also cramping in lower stomach and thirst, wants to know what might be going on. Well taking too much Pepto a week ago can not really have clay colored stool after one week as it is washed away within a few days at the maximum. Hence the most probable cause is obstructive jaundice in which there is obstruction to the outflow of bile due to stone, stricture or cancer. Hence I would advise you the following: Consult your Doctor for a clinical evaluation and examination so that further investigations can be done: Blood: CBC, liver function tests including GGT and Alkaline phosphatase. Stool: Stercobilinogen, bile salts and pigments. may be absent Urine : Bile salts and pigments and routine. Ultrasonography of the abdomen to be confirmed by CT scan or MRCP. Once diagnosed, to get further management as per the reports of investigations .
