I find this interesting, 3 months ago I had total knee replacement surgery and my cycle hasn't been the same since. No gas and oil streaks daily. I've also lost about 25 pounds putting me in the low normal range of BMI. I've started trying to reduce my fat intake to settle myself down a little and try to absorb more food and nutrients, I feel everything is going through without absorbing. While I never did anything crazy with fat, I was liberal with it in my meals. Guess I didn't realize how much fat I was actually eating in a day, I am also one of those that gets constipation from the calcium. I take magnesium with each calcium dose to help. Any suggestions on how to get back to my DS normal?
