Final answer:
Diverticulosis involves small pouches in the colon wall and can lead to diverticulitis if these become infected. It is often caused by increased colon pressure from chronic constipation or low-fiber diets and is more common in older adults. About 10 to 25 percent of those with diverticulosis will develop diverticulitis.
Step-by-step explanation:
Diverticulosis is a condition characterized by the presence of small pouches in the colon wall, known as diverticula. These pouches form in the lining of the large intestine and can sometimes become infected and inflamed, causing another condition called diverticulitis. Diverticulosis by itself is often without symptoms but can lead to complications such as diverticulitis, which may present with symptoms including abdominal pain, fever, nausea, and changes in bowel habits.
The cause of diverticulosis is not fully understood, but it is thought to be related to increased pressure inside the colon, possibly due to chronic constipation or a low-fiber diet. Over time, this increased pressure may cause the formation of diverticula. Diverticulitis occurs when these pouches become inflamed, and the infection is typically caused by bacteria.
Diverticulosis is a condition that becomes more common with age, being particularly prevalent in older adults. Although only about 10 to 25 percent of individuals with diverticulosis will develop diverticulitis, it is still a significant health concern given the large number of people affected by diverticulosis.
