Have used magnesium citrate, but last bloodwork showed high magnesium so Dr. said to stop. Went to GI Dr and he scratched his head b/c she suffers w/low sodium so bad she can't do normal laxatives or her sodium drops and it's an ER visit as heart goes into fibs, etc., Any suggestions helpful Do steel cut oats, apples in a.m. and high fiber waffles. Karo syrup in tea, more apples for lunch w/high fiber soup and whole wheat breads. Eats no refined cookies/cakes, etc. b/c by the time she eats all of her fiber too stuffed for desserts and junk food. Losing weight but difficulty eliminating. Thanks for input.
