He's 55, generally in good health but he keeps having random vomiting attacks.
The first time was after an Indian meal and he put it down to over eating. Felt fine again after being sick, but since then it's happened again several times, a couple of weeks apart.
Tonight, he got in from work, was fine, went for a shower and was violently sick, then fine again and ate dinner as normal.
Is this something he should be seeing a doctor about?. It always passes quickly and he doesn't feel ill before or after.
