hi i m 29.feeling my stomach is upset since 5 months.Episodes of loose stools appera once a month or two.sometimes i take antibiotic and sometimes noting.Very mild abdominal pain also presents sometimes.Another issue is that my bp remains low for a couple of weeks it is 80/50 or sometimes 90/60. Pulse rate is above 90.A month ago i have taken indrol for the treatment of hi pulse and bacame fine but now its again remains high.I feel weeknes most of the time and sometimes feel nausea and vomitng.My medical tests like CBC, Urine RE etc are satisfactory. now, one stomach specialist has suggested to make endoscopy to examine my large intestine.but i m afraid from doing that.I m passing narrow stool than usual but not having blood.
