Is there anything I can do for frequent bowel movements?

A fellow caregiver asked...

I don't have a problem moving my bowels, but in the morning after a cup of coffee I have to move them, and then about a half hour later, I have to move them again and this time it will be softer. Sometimes if I don't move them in the morning, whenever I eat something, then I have to rush to the bathroom. I'm ok the rest of the day after those two scenarios. I can even drink more coffee without having to go again. My biggest problem is that when I have to go, I HAVE to hurry and get to the bathroom and it is embarrassing trying not to go accidentally. I am 72 years old. I take thyroid medication every day and Premarin 3 times a week. I find myself taking Imodium D quite a bit.
