Both characterized as chronic inflammation of the gi tract. They are both characterized as autoimmune disease where the body attacks itself. Comes & goes with "flare ups" then remission.
Diverticulitis begins as diverticulosis which are small pouches in the outer lining of the intestine known as diverticula. These are commonly seen in the descending & sigmoid colon. Diverticulosis is typically caused by a low fiber diet → constipation → increases pressure in the bowels → pushes on weak spots in the lining causing it to bulge out into pouches. When the pouches become inflamed it becomes diverticulitis (inflammation of diverticula) → leads to infection & swelling
Life threatening acute inflammation & infection of peritoneum & endothelial lining. The peritoneum cavity contains 50 ml of sterile fluid, which prevents friction in abdomen during peristalsis. When peritoneum is contaminated with bacteria the body will start fighting it off through inflammation. Vascular dialation will occur allowing transport of leukocytes. If this fails the inflammation will spread causing widespread infection. When diagnosis & treatment are delayed blood vessel dilation continues. The body will respond by shunting extra blood to inflammation (hyperemia) → hypovolemic Shock. Peristalsis will slow or stop in response to severe peritoneal infection & bowel will become distended with gas & fluids. Bacteria can enter blood stream leading to systemic sepsis & septic shock → 💀. Respiratory problems can occur as a result of abdomen pressure against diaphragm. Pain can also interfere with respirations
