Pressure at both sides below waist

Hi

I am 34 old year male.  Usually after waking up in the morning i have proper bowel movement and i poop properly. Afterwards I take tea and again get a bowel movement, this time my poop becomes thinner accompanied with gas, after which I feel satisfied.  You can compare it with a shampoo bottle, which is when full, squeezing results in proper output but when it becomes empty, we have to apply more pressure and shampoo comes out in small quantity with air.

From the last three weeks I am having weird condition. My second time bowel movement has stopped or becomes very less and very thin. And I am having a feeling of pressure at both sides of my waist on the back side throughout day.  I feel dissatisfied, gas and wants to poop, but I get urge to poop at evening only.

I have an ultrasound with no problems. Also thyroid and sugar tests are ok. I have tried antacids with no result. Doctor prescribed me CINTODAC which I am taking from last 9 days with no result. I am taking little frequent diet with fiber and lot of fluid. i tried constipation medicine also

Guys could you please help me with my condition. 

Ask your doctor about IBS and ask for a colonoscopy and celiac test.

Thanks Philippa, I went to gastro today, we agreed on colonoscopy on Monday, meanwhile he prescribed me magnesium tablets zolgas L and polyehelene glycol powder,

Good luck for a speedy diagnosis.

Hi

Today my colonoscopy is scheduled, so as a preparation I have cleared my bowel using prescribed medication, but I am still having that feeling of discomfort at both sides, does it makes sense

I got my colonoscopy done, every thing seems normal..

Now the big question why I m having discomfort? Even empty stomach

If all your tests are negative IBS can be confirmed.  Keep pushing your doctor for answers.
