I'm a 42yo Caucasian male. Since about last August, have had serious constipation. Changed my diet to include less meat, more fiber, more water, more fruits and vegetables. However, to date, I can go 2 - 3 weeks with no or very little bowel movement and, of course, I always feel full. After 2 - 3 weeks of discomfort, I generally resort to an over-the-counter product to assist in bowel movement, and sometimes it doesn't work completely. I've developed an increasingly growing pain in my left abdomen during this time, including under the left rib cage. I sometimes feel pain across my entire abdomen, sometimes just on the left and right sides. The left-side pain and discomfort seems to increase when I lean over or lay on that side, even after those few times when I am able to have a good bowel movement. Though I take very good care of my teeth, my gums have also began receding around some of my teeth during this time. I sweat more, especially under my arms, and feel constantly fatigued.
