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 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 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?

I am African-American, but my skin is not that dark. I was never told that I needed sunscreen and when I worked in a daycare I was told in a very delicate manner that only the paler children needed sunscreen. I've been out in the sun for extended periods of time and was wondering if sunscreen is necessary for someone of my complexion. If so, what strength?

I have been on the pill for over a year now. Recently, I broke up with my boyfriend of two years. We still see each other, but I have not had sex since we broke up. I don't plan on having sex with anybody else. My question is, if I don't plan on having sex for a long while, should I stop the pill? I am afraid that if I decide to get back on the pill, I will have an increased risk of cancer or something like that. Is this true?

1) When you are at the gym exercising do you need to wipe down each machine that you use even if you are not sweating?

2) I'm looking for some helpful pointers you might have on the subject of health club etiquette (i.e., don't wear perfume because others will leave workout equipment wearing your perfume). I would appreciate anything you have to offer on the subject.

What should I eat if I have acid reflux?

I am a 19-year-old male. Over the past three years whenever I urinate, my urine stream splits in two (one continuous stream and one stream which is basically drops of urine.) Is there something wrong??? I also have another question. My grandfather has prostate cancer. I was just wondering when I should begin checks for this type of cancer.
