birth control pill and alcohol

Hi, my healthy 19 year old daughter has been taking the birth control pill for 2 years. She doesn't have any problem with it except that when she drinks alcohol. She is by no means a regular drinker nor does she ever get drunk, but if she has more than 2 beers during the course of long evening, but no more than 3 ...she wakes up in morning feeling nauseous and vomits. Its not a hangover....never has a headache, but more like morning sickness! This has happened every time she has had 3 beers. I or 2 beers doesn't seem to affect her, but the 3rd one I guess does. I have read online comments about other young women on the pill with alcohol like intolerance and ask why the birth control pill may cause this?

I'm 36, been on and off of BC my whole life and find that when I'm on it, I can't handle my alcohol like I can when I'm not on it. I'm a moderate drinker and I just got back on BC after 6 years and had the worse hangover with migraines and vomiting this past wkend. I remember the same thing happening years ago but now I'm positive the 2 are related.

It is studied that alcohol increases your estrogen levels even after one drink.   Could the level of estrogen after 3 beers while taking a birth control pill with 30 mg.estradiol shoot high enough to cause nausea the same way some birth control with higher estrogen cause nausea?

I also am a very light drinker. But for me 1 glass of wine is my max. After that I always vomit the day of or after. I'm a tiny girl, no I don't get hangovers.

I learned something In high school that explains why it happenes to me and maybe your daughter. I learned the body sees alcohol as a poison, so it takes longer to process out of the body, if you drink more than your body can take, your body makes you vomit to save your life. I have an extreme slow digestive system so I usually vomit the next day. Maybe her body processes alcohol very slowly, so maybe she's feeling fine so gets a 3rd beer and BAM the body sees it as poison and danger because its already having trouble processing the beer that has already been drunk. I hope this information helps

I agree, I find it's more to the threshold of the person. My mom has never been able to drink any beer- a sip will cause her to vomit. I too, can only handle one over a long period of time, with food. But when I used to drink I could handle half a dozen shots of whiskey, no problem. The idea now horrifies me and I've been away from alcohol so long that a small glass of champagne on my anniversary gave me the giggles. But the point is everyone has different alcohol tolerances so your daughter won't necessarily drink like you can and also this difference can occur between different forms of alcohol.

It sounds like a hangover to me.  Some people just can't handle much alcohol at all or can't handle much of a certain type.  For me, I can't drink much beer.  It always makes me feel sick the day after, but I can drink other things just fine.  It might just be that your daughter's stomach can't handle beer.  It should have nothing to do with birth control pills, just personal tolerance levels.
