DULUTH — We've all been there. The bloated feeling in the stomach that doesn't go away, and gets worse instead. The growing pressure. The coppery feel in your mouth, and then something inexorable rushing up your esophagus. Suddenly, you're rushing to the nearest bathroom. Your correspondent was undergoing these events a few weeks back when questions occurred: What's going on here? What causes a person to vomit? What would happen if we couldn't? At what point should one seek medical attention?
DULUTH, Minn.—Shadab Rahman's business is sleep, but it wasn't his dream job. "I needed a summer research project," the Harvard Medical School instructor said. "The only available lab was in Toronto. ... They studied sleep." That was when Rahman, now 36, was an undergraduate with an interest in cardiovascular medicine. His summer in Toronto led to a second summer as a research associate at the same lab and then work at another Toronto lab with the same mentor as he achieved his doctorate degree.
