I read that disposable contact lenses are actually worse for your eyes than the normal one-year ones because they allow less oxygen to go to your eyes, and the only advantage is that there are less cleansing problems. Also, it is claimed that inadequate oxygen to your eyes (possibly caused by prolonged wearing of contact lenses) leads to a condition when extra blood vessels sprout around the iris, which leads to sight problems at old age. Is that true?

I am very concerned because I normally wear (one-year) contact lenses from 8am to 8pm, and maybe to 12am during reading periods. I don't feel very comfortable with glasses because they give distorted visions and fatigue. I thought switching to disposable contact lenses would do my eyes good. My current lenses contain 38 percent water. Is this good enough?

1) My girlfriend just saw her ob/gyn and was told that she has a mild yeast infection. Being that we are sexually active, is this something that I should be concerned about?

2) Can a guy get an infection if he has unprotected oral sex with a girl who has a yeast infection?

I'm a 21 year old woman with white lumpy vaginal discharge (odorless)...I thought it was thrush but after two courses of yeast infection cream it has not resolved...I have never had sex, so can't have an STD...I get bad pain in my lower back and sacro-iliac region with my period and with ovulation though I don't know if this is relevant...I'm embarrassed to see a health care professional about this and don't know if I'm just concerned over nothing...

My boyfriend and I have been together for almost three years, and we've lived together for more than one, but I still can't do Number Two when he's in the house. It's not a problem during the week when we both go to our separate jobs, but on the weekends, it's usually just the two of us in the house all day (and night) Saturday and Sunday and if I feel the need to poo, I have to wait until Monday. My question is this — are there any adverse health issues I should be concerned about with waiting to poo? I know that holding your pee can give you bladder infections, but is there a similar issue with Number Two?

What should I eat if I have acid reflux?

I have chronic yeast infections. My doctor basically said that I have a pH imbalance and to stock up on Mycelex or similar creams. This answer, to me, is unsatisfactory. There must be something I can do to keep my pH level in balance, or at least on the acidic side. Do lactobacillus and acidophilus tablets keep the vagina more acidic to prevent a yeast infection?

I had a miscarriaged pregnancy 8 days ago. And for the past 6 days, I’ve been throwing up everything I eat. It's like morning sickness, but morning, noon, and night. And I can't get out of bed without feeling the need to throw up. What do I do? What is wrong?

Do you know anything about the safety of eyelash extensions?
