👉 Postarthritic is a medical condition that occurs when the immune system becomes too active and attacks the lining of the colon or rectum. This can lead to inflammation, pain, and sometimes blood clots in the colon. The exact cause of postarthritic varies from person to person, but it's generally thought to be related to an overactive immune response triggered by stress, infections, or certain medications. Symptoms may include abdominal pain, bloating, diarrhea, constipation, and difficulty passing stool
