constipation, chronic
"Was prescribed Linzess for chronic constipation. Within 6 days I gained 7 pounds. When you're only 120 pounds, 7 is great! I'm an extremely active person and healthy eater. Thought it was water weight from the medicine, but been off the medicine for over a week and still weigh the same. Wish I had seen all the posts online about rapid and stubborn weight gain prior to taking the it!"
