Once a gastrostomy or PEG tube is placed, the skin around it — the stoma — becomes a part of daily care that caregivers manage largely on their own. Most of what shows up there is completely normal: some pink, moist tissue, the occasional bit of drainage, a tube that needs turning. But telling a healing site apart from one that’s starting to get infected is one of the most common sources of anxiety for families managing tube feeding at home. This guide walks through what to check, how often, and what actually distinguishes ordinary healing from a problem worth calling about.
Granulation Tissue: What’s Normal Around a Feeding Tube
Granulation tissue is new tissue the body forms as the stoma heals, and it is extremely common around gastrostomy and PEG sites. It typically looks red or pink and moist, with a slightly bumpy, “beefy” texture — not unlike the inside of a cheek. It bruises and bleeds easily if bumped, and it can produce a yellowish, mucus-like discharge that looks alarming but usually isn’t. Friction from the tube rubbing against the skin, or moisture sitting against the site, both encourage granulation tissue to form or grow. Keeping the site dry between cleanings and minimizing unnecessary tube movement helps keep it in check. Granulation tissue on its own is not an infection and doesn’t automatically need treatment — but persistent overgrowth is worth mentioning at a routine check-in, since some cases benefit from a clinician-directed topical treatment.
Signs That Point to Infection, Not Healing
A true stoma infection is uncommon in an otherwise healthy site, but it’s worth knowing the signs so they don’t get waved off as “just granulation tissue.” Watch for:
- Spreading redness around the tube, especially when there’s no leakage to explain it
- Pain, tenderness, or swelling that’s new or worsening
- Thick green or white discharge, or pus, rather than the thin yellowish fluid typical of granulation tissue
- Foul-smelling drainage
- Skin that feels noticeably warmer than the surrounding area
- Fever, or a firm, painful lump suggesting an abscess
Redness and discharge alone don’t automatically mean infection — both can have other causes — but any of the signs above, especially in combination, is a reason to contact the prescribing clinician or home care nurse rather than waiting it out.
How Often to Clean the Site
Daily cleaning is the baseline recommendation across patient-education guidance, though the exact frequency varies by source and by how recently the tube was placed: some protocols call for cleaning once a day once the site is healed, others recommend one to three times a day in the first day or two after placement or whenever there’s active drainage. A practical approach is to clean at least once daily as routine maintenance, and increase to twice a day temporarily if the site is oozing or newly placed. Hand hygiene before touching the tube or site is the first step every time, regardless of frequency.
The Daily Care Routine, Step by Step
The mechanics of stoma care are simple, but skipping steps is how minor irritation turns into a bigger problem:
- Wash and dry hands thoroughly before handling the tube or site
- Inspect the site daily for redness, swelling, new drainage, or pain, and note any change from the day before
- Clean with mild soap and warm water — skip hydrogen peroxide or antiseptic washes unless a clinician has specifically instructed otherwise, since they can irritate healthy healing tissue
- Swab gently around the tube with a cotton swab or gauze to lift any crusting, then rinse away soap residue with plain water
- Clean under the external bumper or disc once the site is past its initial healing window, sliding it partway down the tube to reach the skin underneath
- Dry the skin fully before letting the site sit open to air — trapped moisture is one of the biggest drivers of both granulation tissue and irritation
- Rotate the tube a full turn daily to prevent it from sticking to the healed tract, and shift the clamp position periodically so the tubing doesn’t weaken at one fold point
If there’s enough drainage to be bothersome, a clean, split gauze dressing changed as soon as it’s damp is reasonable — but once oozing settles down, most sites do better left uncovered, since a dry, air-exposed stoma heals faster than one kept under a bulky dressing.
When Daily Vigilance Pays Off
Because a dietitian is usually one of the professionals coordinating enteral nutrition rather than performing the wound care itself, the practical role here is pattern recognition: knowing what a stable, well-healed stoma looks like day to day makes it much easier to flag the one day something looks different. A consistent cleaning routine, done at roughly the same time daily, turns stoma checks into a habit rather than a source of guesswork — and gives caregivers the baseline they need to tell ordinary granulation tissue from a site that actually needs a clinician’s attention.
