I have had all the following tests: barium swallow, esophageal mamometry (spelling?), 24 hour Ph and endoscopy. Since you asked about
the barium, I'll tell you my experience with that. I had to fast the night before. When I got to the outpatient clinic, I was given a hospital gown and had to take off my top and bra but kept my pants and sneakers on. They then had me stand upright and put an xray view box in front of my chest. This was
open and I was not enclosed like an MRI would be. Just a box in front of you that comes close to your chest. They gave me a bubbly liquid to swallow like alkaselzter would taste. I then had to stand very still while they took several pictures. I was given another chalky liquid to swallow. I would take a small sip and hold it in my mouth. They would say swallow and I did. I did this 3 or 4 times until the liquid was gone. It was kinda chalky but not unpleasant tasting. Next, they started lowering the table back until I was laying on my back. During this they had me roll over very slowly onto my left side, stop, then stomach, stop and right side stop then finally laying on my back. They had had me roll again to my right side and drink water out of straw. All liquids were only 4 - 5 ounces of each. The table moves back into position so you are standing again and the test is finished. Took less than 15 minutes. After they told me to make sure you drink lots of water to help the barium leave your system. They said gas pain, bloating could be a side effect but I didn't have any. Hope that helps. Good luck.
