I wanted to give an update on this for anyone else who experiences it, which I learned from visiting a GI doctor:
Those white specks are caused by constipation, regardless of the reason you’re constipated. You can still be constipated even if you’re having bowel movements daily, especially if you’re not having a full bowel movement (for example, if you push when you go to the bathroom, you’re turning off your body’s peristalsis and you will not have a complete movement, aka some will still be left in there).
The white specks are coagulated mucus that your body produces when you’re constipated to try to help things move along and get the excrement out of your system. When that mucus is in your body for too long (because you’re constipated), it turns into little white specks/dots/etc. It’s kind of like the calcification that happens when people get tonsil stones.
Solution found with the help of my GI and physical therapist:
(1) I cut back on my Soylent intake a little, but I still drink Soylent daily and love it.
(2) I started eating more regular food. Do not go crazy eating vegetables if you’re constipated because it will have the opposite effect and not help you.
(3) I began doing pelvic floor exercises. If you have constipation, these are a must and a life saver. Once the pelvic floor exercises start working for you, immediately stop all laxatives and similar (like Linzess). Those are not good for your gut but they’re necessary until you build up your pelvic floor muscles.
(4) Walk for at least 30-60 minutes a day and drink a bottle of water during that walk.
Those solved my constipation problem entirely (and I didn’t even know I was constipated since I had a BM daily), and now I’m 100% back to normal. I haven’t seen a white speck in many months.
Good luck to anyone else with this problem. There is hope!
