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 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?

After every meal, I get serious gas, bloating, and other yucky stuff. This is with ALL kinds of foods. I'm taking fiber for constipation, which is cool, but I get messed up even long after I take my fiber. What's the story?

I have had terrible stomach problems for a few years now. My doctor says it's due to my love of greasy and oily foods, and that I should concentrate on eating healthier, broiled foods. Do you think if I continue on this unhealthy eating cycle, that I could develop gallbladder problems? Also, do you think my diet contributes to my acne-prone skin? Thanks for your help.

1) I've suffered weird digestive things when I have my period. The way I have heard it explained in my MCAT class is that the same hormone that causes the smooth muscle of the uterus to contract unfortunately works on all of our digestive organs as well, particularly the large intestine. So that's how I've come to grips with the apparent confusion of the digestive processes during my period.

2) Does a person's menstrual cycle regulate her bowels in any way? I have had some problems. The week before I get my period, I have loose bowels and the week afterwards I am quite constipated. Is this normal? Is there anything I can do?

What natural food or herb can help soothe stomach ulcers?

I have had Crohn's disease for 16 years and am in remission right now. Recently my boyfriend and I have been toying with the idea of anal sex, but I'm concerned about it given my health issues. I have a lot of thickening of the terminal ileum walls and worry that the "trauma" of anal sex could set off a flare up and be painful because of the narrowing. Any thoughts? I'm way too embarrassed to discuss this with my male doctor. Thanks!
