Dear Dr. Roach: I always thought that I had a cast iron stomach; however, after a bout of suspected food poisoning about six months ago, I’ve had two incidences of violent vomiting for about a half hour. Both of the preceding two meals included shrimp, which I have eaten often in the past without a problem. The episodes were just a month apart. In trying to find an answer, I was surprised to read that shellfish allergy can develop suddenly in adults. I’m afraid to eat it again, and I’ll follow up with my doctor for an allergy test. —…
Could violent vomiting be shellfish allergy?
Allergies to fish and shellfish affect about 3% of U.S. adults. Shrimp is most likely to cause an allergy. Severe reactions can even lead to death.
