What is the prevalence of Ostomy?

An ostomy is a surgical opening that allows waste to leave the body, and it is estimated that over 700,000 to 1 million people in the United States currently live with an ostomy. While not a rare disease itself, the underlying conditions necessitating an ostomy vary widely, with approximately 100,000 new ostomy procedures performed annually in the U.S. alone.

How common is the use of an ostomy?

Because an ostomy is a surgical outcome rather than a single disease, it is considered a common medical procedure rather than a rare condition. Prevalence data is challenging to aggregate globally because registries often track the primary diagnosis—such as colorectal cancer, inflammatory bowel disease (IBD), or diverticulitis—rather than the ostomy status itself. Current estimates suggest that the prevalence of living with an ostomy is approximately 1 in 500 to 1 in 1,000 people in developed nations.

What factors influence the prevalence of an ostomy?

The distribution of individuals living with an ostomy is influenced by several clinical and demographic factors:

• Age Distribution: While an ostomy can be required at any age, the incidence increases significantly in adults over age 60 due to higher rates of colorectal cancers and diverticular disease.


• Gender Distribution: There is no significant biological predisposition, though some studies suggest slight variations based on the prevalence of specific underlying diseases (e.g., higher rates of certain cancers in males).


• Geographic Variation: Higher prevalence rates are generally observed in Western countries, likely correlating with better access to surgical care and higher screening rates for the conditions that lead to an ostomy.

Why is accurate data on the number of people with an ostomy difficult to obtain?

Obtaining precise global statistics for an ostomy is difficult due to the "invisible" nature of the procedure and the lack of a centralized international registry. Many patients are managed in outpatient settings, and once the ostomy is established, it is often not recorded in national health databases as a primary status. At DiseaseMaps.org, we have 286 people with an ostomy who have joined our community, providing a vital, real-world perspective that complements clinical data by highlighting the lived experience beyond surgical statistics.
