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 use Nalgene bottles for about 75 percent of the water I drink each day. Therefore, I was startled to find out that there is some possibility that these bottles leach chemicals into the water. I've found conflicting opinions about the veracity of these claims on the Internet. What's the truth? Should I dump my Nalgene for glass? You have an earlier post about bottled water, but it doesn't seem to address this issue specifically, and you recommend purchasing reusable bottles like the ones that might be poisoning me. The bottles I use have #7 on the bottom in the recycle symbol.

1) Which is better for you, tap or bottled water?

2) How bad is the water here in New York City? Do you recommend drinking filtered water, or does it really make a difference?

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???

Why is your favorite food very tasteless when you have a cold?

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 love sushi, sashimi, and oysters on the half shell. I apparently am uneducated (ignorant) when it comes to the health risks associated with eating raw seafood. I read in an article that a person could contract hepatitis A and worms. Is hepatitis A something that is "curable"? Are ANY of the diseases/problems associated with eating raw fish NOT "curable?"

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?
