Hi doctor,I have some major problems with my small intestines. I have cramping pain in my lower abdomen, and I suffer from indigestion, bloating, burping, and nausea. Nausea seems to originate from my lower intestine. If I smoke, it makes me nauseous. I have a constant feeling that something in my lower intestine is irritating. I do not have diarrhea or constipation. I go to the toilet every morning, and the stool looks normal. I feel my appetite has gone down because of all the air in the intestine. I cannot digest fatty foods, milk, and some fruits. I know it is not IBS. If I massage my belly, I get a burning pain in my lower abdomen. I feel like there is some obstruction in my intestine.I did an upper gastrointestinal endoscopy, and it is fine. The ultrasound showed the ileum is full of air and there are no visible thickening. Then, I got UTI, and I was given Macrobid antibiotics for it. This antibiotic helped my stomach also, as the burping had stopped. But, the symptoms started again when I stopped taking the tablets. It always feels like something inside is irritating, and I saw fresh blood in the stool one time. Probiotics do not help much, and I cannot sit for long because it feels like my anus will explode. The food is not passing normally through the gastrointestinal tract.It all started after taking some Magnesium pill. I felt as if something was swollen from the inside, and I passed less stool. Then I was given PPI, and it made things worse. Bending over makes me nauseous. All this is going on from the past three months. I even stopped smoking, but it is not getting better. Whenever I smoke, I start feeling nauseous again. I know it is not stress-related or IBS. How much of small intestine is seen using colonoscopy? What could this be? I lost weight due to poor absorption. I do not think it is cancer, as I had a colonoscopy two years ago, and it was fine, but back then, I had no such problems. What test needs to be done? Will an x-ray with barium show if there is an ulcer or inflammation or obstruction? What do you suggest? It is ruing my life.
