There was a test I took in a gasteroenterologist office to see how sensitive you are to milk. They asked me to drink a large glass of whole milk and after 10 minutes or so I had to blow into these mylar like balloons. They then read the gas expelled in some kind of meter. They told me that I was the most highly sensitive patient they ever had to milk. I am not sure if they were measuring lactose intolerance or other substances in the milk. I used to be able to drink milk and have ice cream no problem until I got this disease. Anyone else get this?
