This topic is about changes in stoma size, as well as bruising and skin discoloration around the stoma. A person who has had their stoma for a year is noticing some changes and is seeking advice. Here are some helpful insights and advice shared by others:

1. Normal size change
- It's common for a stoma to shrink gradually during the first 3-4 months after surgery, sometimes taking longer, before it stabilizes.
- Abdominal swelling from surgery can also take months to settle down.

2. Color under the flange/convex barrier
- A darker red or bruised-looking ring where the flange or convex barrier sits is common and doesn't necessarily mean irritation.
- Convex barriers often leave a pronounced red area even when the skin is healthy.

3. Check flange opening and skin contact
- If the hole in the flange is too large, it can allow effluent to irritate the skin, which might look like bruising.
- It's important to re-measure the stoma and cut the flange to fit closely. Consulting a Stomal Therapy or Ostomy Nurse for sizing can be helpful.

4. Possible hernia
- A rapid increase in stoma diameter, along with local swelling and pain, might indicate a parastomal hernia, and medical evaluation is advised.
- Parastomal hernias are common and can be noticeable, sometimes making clothing difficult to wear.

5. Skin care and comfort tips
- Using Savlon antiseptic cream on blotchy or irritated peristomal skin can be soothing.
- Removing the pouch and showering or bathing when output is quiet helps keep the skin healthy.
- Seals, like Hollister or Eakin Cohesive seals, placed under the pouch can prevent leaks and burning.

6. Product experiences
- The Eakin Pelican pouch with a split-cover is praised for its security and reliability.
- Hollister and Eakin brands are mentioned for their effective barrier rings and seals.

7. General reassurance
- Most stomas reach a steady size, though occasional changes can occur. Ongoing problems should be reviewed by a healthcare professional.
