Stomach disorder..CT Enteroclysis Radiation Dose?

I am a 20 year old male..i have been suffering from severe ibs for the past three years

Symptoms include altered bowel habits, high heart beats after meal, palpitations, anxiety, smelly unformed stools and cloudy/smelly urine occasionally..i feel weak after passing stools and there is palpitation in my hands and legs that i can feel...My stools were never formed properly unless otherwise i was constipated..and there were occasion when i would excrete only mucus out with a lot of pain...

Last december..i had suffered a very painful and severe stomach ache and sometime prior to that..i had bleeding with stools..which regularly happen..but this time..the qty was high..

Since i had the problem for three years(2 and half back then).and there was absolutely no control over the problem..the doctor suggested a ct enteroclysis. In a hurry situation..i accepted the test out of anxiety that there is something wrong..without even telling my family members too.
The procedure involved a 15 to 20 minute fluroscopy guided tube being injected through my nose and a ct scan of the abdomen where i had to hold my breath for 10 seconds a few times.may be 3... every thing came back normal..

There were 3 axial and 1 coronal scan film that was given to my MD after the scan..each performed at 110 mAs and 130 kva...

I want to know how much radiation is involved in the whole process..and how would it impact my body in the future..

I feel helpless...wierd..

Hoping to get a reply soon..
