What Causes Fast Heartbeat After Bowel Movements?

Right before and after most bowel movements my face, ears, and arms turn bright red and heart rate increases. Sometimes I have bouts of excessive urination and urine is completely clear and have urge to urinate very often. I also turn bright red when stressed. I had 2 abdominal CT scans and ER Dr only found an inflamed valve in colon and said IBS. Also did EKG in ER and everything ok. Few years ago with same symptoms had endoscopy and colonoscopy, long term urine test done, and blood sugar tested, all negative. Any ideas what could be causing these episodes?

Hi.
Thanks for your query.
Noted the history of bright redness and increased heart beats before and after each bowel movement. bouts of excessive urination, frequency. Also turn bright red on stress. All the investigations you mentioned are normal hence the Doctor says this to be IBS.
My thoughts.
Since there are symptoms there must be reasons. The test that you underwent do not cover to find the cause.
I would advise you the following:
Clinical evaluation by your Doctor and reference to the Gastroenterologist and others as per the clinical evaluation.
Tests for 5-HIAA in urine for carcinoid syndrome as a possible cause, CT scan can miss carcinoid if small.
Tests of stool for any infection.
Other tests of blood: thyroid functions.
This may be due to anomoly of the autonomous nervous system. The surge can be over-activity of the parasympathetic nervous system and hence the classical symptoms.
Get an opinion of a Neurologist too.
