A surgical procedure meant to counter ulcerative colitis, an immune disease affecting the colon, may trigger a second immune system attack, a new study shows.
The study results revolve around the immune system, the cells and proteins that destroy invading bacteria and viruses. Activating it brings about inflammation, responses like swelling and pain that result from cells homing in on the site of infection or injury. Autoimmune diseases like ulcerative colitis occur when this system mistakenly damages the body’s own tissues.
