Many people have small pouches in their colon (large intestine) that bulge outward creating what is called a diverticulum. This condition is also known as "diverticulosis."
The condition becomes more common with age and about 10 percent of Americans over the age of 40 have diverticulosis. Nearly half of people over age 60 have diverticulosis.
When these pouches become infected or inflamed it is called "diverticulitis" as anything that ends in "-itis" means inflammatory diseases. This condition happens in 10 to 25 percent of people with diverticulosis. You can read more in my other posts.
This condition known as "diverticulosis" causes bleeding. Not when these pouches become infected or inflamed. That it is called "diverticulitis."
It is the most common cause of lower gastrointestinal bleeding.
It is uncommon before 60 years of age. It is most common after age 70.
Regular use of nonsteroidal anti-inflammatory drugs doubles the risk
You may receive blood products and fluids.
Your colon may be cleaned out of all stool and blood with a colonoscopy prep.
Your doctor may consider ordering a CT angiography or an embolization to stop the bleeding.
You may go on a clear diet, placed on bed rest, and be under "observation."
That depends if there was a colonoscopy completed in the recent past.
Also on the clinical presentation that would determine if the lower gastrointestinal bleeding makes it a "high-risk" diverticular bleed.
High-risk patients are those most likely to have poor outcomes—such as those with "unstable vital signs, hematocrit below 35%, age over 60 years, and comorbidities." These high-risk patients should undergo colonoscopy within 24 hours.
Guidelines from the American Gastroenterological Association on diverticulitis recommend colonoscopy six to eight weeks after diagnosis.
