barium is notorious for causing constipation so i suggest that you consult your medical provider for a patient-specific treatment suggestion.
can a small bowel series with barium swallow cause constipation? . i have been losing weight and am now approx. 20lbs under the lowest gauge for my height (5' 4"). i've had an endoscopy colonoscopy and a small bowel series with barium swallow. ever since the small bowel series i've had constipation/very little movement of the bowels. can barium cause a gastric blockage?
