Pooping out your intestinal lining can be a result of inflammatory bowel disease, infections, diverticulitis, trauma, polyps and even certain medications.
Inflammatory bowel disease including Crohn's disease and ulcerative colitis is the most common cause of pooping out your intestinal lining.
Ulcerative colitis as well as Crohn's disease can cause inflammation of your intestinal lining and result in shedding of cells and mucus which can be what you're experiencing when you poop out your intestinal lining.
And bacterial infections, viral infections or even parasitic infections can also damage your intestinal lining and result in shedding of the cells.
Diverticulitis which is a result of small pouches in your intestinal wall called diverticula becoming inflamed can cause irritation and shedding of your intestinal lining.
Polyps which are non cancerous growths on your intestinal lining can also sometimes shed cells and mucus and result in you pooping out the intestinal lining.
Physical injury or trauma to your intestines can also damage the intestinal lining and cause shedding or pooping out of your intestinal lining.
And certain medications like antibiotics and chemotherapy drugs can affect your intestinal lining and also lead to shedding of the intestinal lining.
The symptoms of shedding of your intestinal lining are passing small, slimy or bloody pieces of tissue in your poop, abdominal cramping, diarrhea or constipation and sometimes nausea and vomiting.
You should go to the doctor to get checked out and the doctor can do tests like an endoscopy or colonoscopy to find the underlying cause of pooping out the intestinal lining.
Treatment for pooping out your intestinal lining can include medications or surgery or even changes in your diet.
