Is there any chance that because I get low blood sugar occasionally, I may become a diabetic someday? And what can you keep with you to take when your levels do drop, and you can't get to any food or juice?

I'm wondering about Lyme disease and chronic fatigue syndrome — the differences and similarities?

I am not actually worried but simply curious. When petting with my boyfriend and getting in contact with his sperm, my skin turns slightly red where his cum touches me. Am I allergic, or is there perhaps any other explanation? I am 24 years old and female.

I just found out I tested positive for high-risk HPV. My pap smears have been normal for years. I'm 45 years old and have had lots of basal cell skin cancer. I'm scared to death of getting cancers that are caused by HPV. I'm so stressed. What are the odds that I will actually get cancer, now that I am supposedly high-risk? It appears there it nothing I can do at all to prevent this from happening other than keeping up with my visits and pap smears and hoping I beat the odds. I just wonder at how much risk am I when they say I am HIGH-RISK???

1) This is in reference to your Missed periods Q&A. Another cause of missed or late periods is PCOS (polycystic ovary syndrome). A lot of health care providers don't seem to be aware of this syndrome. In this syndrome, missed or irregular periods are caused by unusual hormone levels, sometimes in combination with insulin intolerance. Because missed and irregular periods cause scar tissue build-up in the uterus (which may cause endometrial cancer) and may cause infertility, it is important that your readers know to ask their health care provider about this syndrome. There are obviously other symptoms and complications, but I just thought that I might mention it to you so that you might read up on it for your readers. Thank you.

2) I was recently diagnosed with polycystic ovary syndrome (PCOS). I'm only 17 and am afraid that this will affect my chance of having children. Should I worry? Also, I know birth control pills will help me regulate my period, but if I take them, will it stop the effects PCOS has on me? Like me gaining rapid weight, missed periods, and losing my hair? This is really worrying me. Can you inform me on this syndrome?

I've been swimming a lot this summer and I have noticed a green tint to my blond hair. Is this caused by previous dyeing? Is it possible to remove the green tint? Thanks for your time.

I have a friend who will be going through chemotherapy and radiation. What can she do to build herself up to keep her body in the best condition possible?

I have dandruff that responds well to over-the-counter shampoo. Ergo, I have been using the stuff almost exclusively for ten years. No brand in particular, sometimes zinc pyrithione (the blue stuff!), sometimes coal tar (the smelly brown stuff!). Anytime I switch to non-dandruff shampoo for like three to four days straight, I get my dandruff back. I worry that I might be addicted to dandruff shampoo. Should I worry?

Ever since high school, I've had very oily hair and skin, but it became worse in college. Now I'm in my mid-twenties and have to shampoo my hair about 10 times each day to get it clean. Then by evening it's already oily again. This isn't my scalp trying to moisturize itself after being over cleaned, because I've tried not washing it completely and it's even oilier the next day.

Are there any special shampoos or medications that help reduce oily skin? I've tried some facial products from my dermatologist, but they haven't reduced the oil production. This is an embarrassing problem and limits the overnight activities I can do, like camping or staying with friends.

I have an invisible disability and I'm really getting into disabilities activism. Even in liberal circles ableism is still pretty accepted and this upsets me. However, when I try to educate people around me, it sometimes goes awry. I had one friend get upset when I called her out for using the word "retard." Another got upset when I pointed out that her Facebook post of inspirational people with disabilities (that just showed people with disabilities doing normal things) was a little offensive and tried to tell her about "inspiration porn." I get that using the word "retard" is normal as is "inspiration porn." I just don't think it should be.

I know my friends are caring, socially conscious people. I expect people to be a little upset, but ultimately I would also expect them respect the fact that it's really not OK to objectify people with disabilities in the way that inspiration porn and the use of words like "retard" do. What I want to know is how do I point out that people are expressing a harmful social bias, without having them get so upset that they write me off as an over sensitive concern troll?
