poop question ( sorry )

Yes.  Yellow is a sign of excess bile.  Some people with IBS have that problem (probably because of rapid transit times--they don't have time to absorb it properly), but a lot of people without gall bladders have that problem.  I guess it's just because you're constantly dripping bile out--not just releasing it when you have food to mingle with it. 

That's what I take the Welchol for.  It absorbs that excess bile and keeps me from having diarrhea.  My poops are also less yellowy as a result. 

Before I had GB troubles, I had occasional constipation problems all my life; I can still get constipated--although only while on medicine. My basic rule of thumb is to take one pill a day. If my guts start acting up, I take a second one. If they're still acting up 30 minutes later, I take a third, and so on until I stop having diarrhea. But most days one will do me. If I start to get constipated, I will not take one that day and will not take another until my poops start getting loose again. So basically you can take it as a preventative and you can take it like an immodium for instant relief. You just have to monitor how your bowels are moving and take as needed.

I read about the bile salts online--that's where I saw where you can buy some. I'd try looking for them at a reputable herbal place online. You can also try treating your constipation with aloe vera capsules. Take those as nescessary while you are constipated, then lay off them and go back to the Welchol if you get loose again.

I don't know if the Welchol helps stomach acid as I don't have stomach acid problems. As a cholesterol med it is made to work in the last part of the bowels (it absorbs the bile and keeps it from breaking down that last little bit of food so you don't absorb that last bit of cholesterol in your food). But since your refluxing excess bile up into your stomach, it may help.

But one problem fixed is better than none, right? Oh, and since you can have C sometimes, you have to be careful with the Welchol and monitor your poops. If you start getting a little C, don't take a Welchol as it will make it worse. When you start getting a little loose again, start back on the Welchol. I have to adjust my dosage pretty frequently in order to have a happy medium with my bowel movements. It's rather like being diabetic and having to adjust your insulin based on what you've been eating or doing. What you eat will affect whether you need a Welchol, extra Welchol or none at all. Stress will affect you too. Pity we don't have something like a blood glucose monitor to tell us ahead of time whether we need Welchol now or not. But after a while, you'll be able to read yourself pretty well and will know that odd feeling in your stomach is going to mean diarrhea as soon as you eat, so take the Welchol now and give it 30 minutes before you eat.
