Hi,I've suffered from IBS-D for a few years, with it being so bad at one point that I was totally housebound and had to quit working. Then I started taking Caltrate and watching my diet, and I haven't had an attack in months. But I just read that calcium can cause other medications to bind to it, causing them not to absorb into your system. Does anyone know if this is true? I take a few medications, for example-hormone due to hysterectomy last year. Anyway, if anyone knows the answer to this I'd really appreciate it!Thanks!
