The first time you look closely at your stoma, it can be difficult not to wonder, “Does this actually look normal?” A change in colour, a little blood during cleaning, or a difference in shape can be surprisingly worrying — especially when you are still getting used to your body.

The good news is that stomas can look different from one person to another. They can vary in size, shape and how far they sit above the skin. Knowing what is normal for your stoma makes it much easier to notice when something genuinely needs attention.

So, what does a healthy stoma look like, and which changes should you discuss with your stoma nurse or GP?

What Does a Healthy Stoma Look Like?

A healthy stoma is generally pink to red, moist and soft-looking, rather like the inside of your mouth. This colour comes from the bowel tissue having a rich blood supply. (Colostomy UK)

Your stoma may be round, oval or slightly irregular. It might sit fairly flat against your abdomen or protrude from the skin, depending on the type of stoma and how it was formed.

There is no single “perfect” stoma appearance. What matters most is understanding what is usual for you and being alert to significant changes.

A normal stoma may be:

• Pink, red or reddish-pink
• Moist rather than dry
• Soft to touch
• Slightly swollen after surgery
• Different in size or shape from another person’s stoma
• Able to change slightly in length as the bowel moves

For people who have recently had surgery, swelling is particularly common. A new stoma can gradually reduce in size over the following weeks, so your stoma nurse may need to reassess the fit of your stoma bag during recovery. (Plymouth Hospitals NHS Trust)

Understanding Healthy Stoma Colour

One of the easiest things to notice is colour, which is why healthy stoma colour is often a major source of reassurance — and concern.

Generally, a healthy stoma is pink or red. A rich red or pink appearance can indicate that the stoma has a good blood supply. (Ileostomy & Internal Pouch Association)

It is also possible for your stoma to look slightly different at different times. Movement of the bowel can cause it to appear a little longer or shorter, for example. (Ileostomy & Internal Pouch Association)

What matters is a noticeable change from your usual appearance.

When colour changes need attention

If your stoma becomes unusually dark, purple, blue, grey or black, do not simply assume it will return to normal. A significant colour change can indicate a problem with the stoma’s blood supply and should be assessed promptly.

If you notice a sudden or concerning change in colour, contact your stoma care nurse or healthcare team for advice. If you are unsure how urgently you need help, NHS 111 can provide guidance. (nhs.uk)

Should a Healthy Stoma Bleed?

This is one of the most common things people worry about.

Because stoma tissue has a strong blood supply, a small amount of bleeding can happen when the stoma is rubbed or cleaned. Seeing a small spot of blood on your cleaning cloth does not automatically mean something is wrong. (Colostomy UK)

The important distinction is between minor spotting and heavier or persistent bleeding.

Contact your stoma nurse or GP if:

• Bleeding does not stop
• There is a lot of blood
• Blood appears to be coming from inside the stoma
• You notice blood in your stoma bag or output
• The bleeding is accompanied by other concerning symptoms

If you take medicines that affect blood clotting, it is particularly important to discuss unexpected bleeding with your healthcare professional. (Colostomy UK)

What About the Skin Around the Stoma?

Your stoma itself can look healthy while the skin surrounding it becomes irritated, so it is worth checking both.

The skin around your stoma should generally look similar to the surrounding abdominal skin. Redness, soreness, broken skin, burning, itching or persistent discolouration can indicate irritation. Leakage, pressure and friction are some possible causes. (mkuh.nhs.uk)

A well-fitting stoma bag can help protect the surrounding skin by reducing contact with output. If you repeatedly experience soreness or leakage, speak with your stoma nurse rather than simply putting up with it.

Your stoma nurse can check the fit of your appliance and help identify whether a different product or approach would suit you better.

Healthy Stoma Signs to Look For

When you’re checking your stoma, it can help to have a simple routine rather than examining it anxiously every time you change your bag.

A quick stoma check

Look at your stoma during your usual pouch change and ask yourself:

1. Is the colour similar to normal for me?
   Pink or red is generally expected.
2. Does it look moist and healthy?
   Stoma tissue normally has a moist appearance.
3. Has its shape or size changed noticeably?
   Some variation can be normal, particularly after surgery, but significant changes should be discussed.
4. Is the surrounding skin comfortable?
   Look for redness, soreness, broken skin or irritation.
5. Is the stoma working as usual for me?
   Changes in output can sometimes be important, particularly if output stops unexpectedly.
6. Do I feel unwell?
   Pain, nausea, vomiting, swelling or other new symptoms should not be ignored.

This simple check can help you become familiar with your own stoma appearance, rather than comparing it with photographs or somebody else’s stoma.

When Should You Contact Your Stoma Nurse or GP?

Not every unusual-looking change is an emergency, but it is always reasonable to ask for professional advice if something doesn’t seem right.

The NHS recommends contacting your stoma nurse or GP if you think there is a problem with your stoma or if you develop skin problems around it. (nhs.uk)

You should seek urgent medical advice if you experience symptoms such as:

• A significant or sudden change in stoma colour
• Heavy bleeding
• Severe abdominal pain
• Significant swelling
• Nausea or vomiting
• Your stoma stops producing output for much longer than is normal for you
• Signs of dehydration

These symptoms can sometimes be associated with complications such as infection or bowel obstruction, which require prompt medical assessment. (nhs.uk)

If you’re unsure whether a change is important, you don’t have to make that decision alone. Your stoma care nurse is there specifically to answer these questions.

Remember: Your “Normal” May Look Different

One of the most reassuring things to remember is that there is no universal template for a normal stoma.

An ileostomy may look different from a colostomy. A newly created stoma may look different from one that has been established for years. Some stomas protrude more than others, while some sit closer to the skin. (nhs.uk)

Instead of asking, “Does my stoma look exactly like everyone else’s?”, a more useful question is:

“Does my stoma look and function the way it normally does for me?”

Getting familiar with your own healthy stoma signs can make everyday care feel much less intimidating. And if something changes, your stoma nurse or GP can help you understand what is happening.

For additional UK support, organisations such as Colostomy UK and Ileostomy & Internal Pouch Association (IA) also provide information and support for people living with a stoma. (Colostomy UK)

Final Thoughts

Learning what a healthy stoma looks like can take time. In the beginning, even small changes may make you nervous, but gradually you will become more familiar with your own colour, shape, output and surrounding skin.

Your stoma does not need to look “perfect” to be healthy. What matters is recognising what is normal for you and getting professional advice when something changes or concerns you.
