Each year, thousands of Americans undergo ostomy surgery for conditions ranging from colorectal cancer to inflammatory bowel disease. For many patients and caregivers, understanding what a stoma is becomes one of the first steps in adapting to life after surgery.

A stoma is a surgically created opening on the abdomen that allows waste to leave the body when part of the digestive or urinary system can no longer function through its normal pathway. Depending on the type of surgery performed, stool or urine passes through the stoma and is collected in a specialized pouching system worn outside the body.

While the concept may seem unfamiliar at first, stomas help millions of people worldwide continue living active and fulfilling lives after surgery.

What Is a Stoma?

A stoma is an opening surgically created on the abdominal wall that allows stool or urine to leave the body through an alternate route. Waste exits through the stoma into an external ostomy pouch designed to collect output safely and discreetly.

Understanding the Difference Between a Stoma and an Ostomy

Difference Between a Stoma and an Ostomy

Many people use the terms "stoma" and "ostomy" interchangeably, but they have different meanings.

  • Stoma: The actual opening visible on the abdomen.
  • Ostomy: The surgical procedure used to create the stoma.

For example:

  • A colostomy procedure creates a colostomy stoma.
  • An ileostomy procedure creates an ileostomy stoma.
  • A urostomy procedure creates a urinary diversion stoma.

Understanding this distinction can make it easier to navigate educational resources, product information, and healthcare discussions.

How Does a Stoma Work?

To understand how a stoma functions, it helps to first understand how the body normally eliminates waste.

Under normal circumstances:

  1. Food passes through the digestive system.
  2. Nutrients are absorbed into the body.
  3. Waste moves through the intestines.
  4. Stool exits through the rectum and anus.

When disease, injury, or surgery affects this process, healthcare providers may create a stoma to establish an alternate pathway.

Step-by-Step: How Waste Leaves the Body Through a Stoma

  1. A portion of the intestine or urinary tract is brought through the abdominal wall.
  2. The tissue is carefully attached to the skin.
  3. Waste then leaves the body through the stoma and is collected by an ostomy pouch designed for that type of output.
  4. An ostomy pouch collects the output.

Unlike the anus, a stoma does not contain sphincter muscles. As a result, individuals typically rely on pouching systems to manage output.

Why Are Stomas Created

Healthcare professionals may recommend ostomy surgery for a variety of medical conditions.

Common reasons include:

  • Colorectal cancer
  • Bladder cancer
  • Crohn's disease
  • Ulcerative colitis
  • Diverticulitis
  • Intestinal obstruction
  • Traumatic injury
  • Congenital abnormalities
  • Complications requiring bowel diversion

Some stomas are temporary and may later be reversed, while others are intended to be permanent.

The Three Main Types of Stomas

Colostomy

A colostomy involves bringing part of the colon through the abdominal wall.

Common characteristics:

  • Output may be more formed.
  • Often positioned on the left side of the abdomen.
  • Can be temporary or permanent.

Ileostomy

An ileostomy is created using the ileum, the final section of the small intestine.

Common characteristics:

  • Output is generally more liquid.
  • Often located on the right side of the abdomen.
  • May require specialized hydration considerations.

Urostomy

A urostomy diverts urine away from the bladder.

Common characteristics:

  • Continuously drains urine.
  • Requires a urinary collection pouch.
  • Commonly performed after certain bladder surgeries.

IleostomySmall intestineLiquid stoolRight abdomen
UrostomyUrinary diversionUrineLower abdomen

What Educational Resources Commonly Say About Stoma Appearance

Although every person is unique, characteristics often described in educational resources for a healthy stoma are as follows:

  • Pink or red in color
  • Moist in appearance
  • Slightly raised above the skin surface
  • Round or oval in shape

Because a stoma is made from intestinal tissue, it is different from surrounding skin tissue.

Medical Disclaimer: Appearance can vary significantly between individuals. Any changes in stoma appearance should be discussed with qualified healthcare professionals. This article is educational and should not be used to assess medical conditions.

Living With a Stoma: What Daily Life May Look Like

One of the biggest misconceptions about ostomy surgery is that it prevents people from living active lives.

In reality, many individuals with ostomies continue to:

  • Work full-time
  • Exercise regularly
  • Travel domestically and internationally
  • Participate in hobbies
  • Attend social events
  • Enjoy outdoor activities

While adjustment periods vary, access to proper supplies, education, and support can make daily management more convenient.
