My daughter gags when she has a cold instantly, causing her to vomit every time. So when she get a cold, I know I have to watch her when the cold gets to the point of massive congestion. It happens EVERY TIME! I am not sure if this gagging is related to CAH or not. BUT, this is something to think of. I know whenever I go on birth control pills, a dose that is strong, it causes havoc with my own sytem. I could easily barf in the morning. I used to take at night. Not that I am a doctor but is it the high estrogen that is in birth control pills. What happens to a CAH patient estrogen level when their OHP is too high or low? Anyone?
