This topic is about managing chronic diarrhea, leaking barriers, and irritated skin around a stoma, especially for someone undergoing oral chemotherapy. Here are some practical tips and insights to help manage these challenges:

1. To slow or thicken output for appliance changes:
- Try eating 3 large marshmallows about 15-20 minutes before changing your appliance. Many people find this helps.
- Other foods that can help thicken output include white rice, pretzels, and dry cereal.
- Talk to your oncologist about anti-diarrheal medications, as chemotherapy like FOLFOX can increase output.

2. Techniques for applying barriers to extend wear time:
- Ensure your skin is completely clean, dry, and warm. You can use a hairdryer on a low, warm setting.
- After fitting the wafer or pouch, press it firmly with warm hands for 30 seconds to 10 minutes. Some people find lying down for a few hours after an evening change helps.
- Cut the wafer opening just large enough for the widest part of your stoma to avoid exposing skin.
- Wrap your stoma with tissue or gauze while preparing the area to catch any output.
- For two-piece systems, snap the pouch to the wafer before applying pressure to seal.

3. Products and accessories to improve the seal:
- Use barrier rings snugly around the stoma and mold them to fill any creases.
- Ostomy pastes can be applied to the ring or wafer to fill uneven skin folds.
- Consider using an adjustable ostomy belt to hold the wafer firmly in place, especially in the first few hours after application.
- Experiment with different manufacturers’ wafers and rings to find what works best for high-liquid output.

4. Protecting and healing skin with "crusting":
- Step 1: Dab a sting-free barrier wipe over red skin.
- Step 2: Dust stoma powder (or prescription Nystatin powder if yeast or fungal issues are suspected).
- Step 3: Gently remove excess powder and re-dab with the wipe.
- Repeat 2-3 layers, finish with the wipe, let the area dry, then apply the wafer.
- Fresh aloe gel can be soothing before starting the crusting process.

5. Inspect for fungal infection:
- If you notice uniform circular redness under the wafer, it may indicate a yeast infection. Consult a nurse or doctor for assessment and possible antifungal treatment.

6. Gentle removal to protect skin:
- Loosen the wafer with a warm, soapy washcloth to avoid ripping.
- Rinse away soap thoroughly, pat dry, and then proceed with skin preparation.

7. General tips:
- Change your appliance over the sink or toilet to reduce mess.
- Keep spare supplies, tissues, and cleaning wipes nearby.
- Be prepared for extra changes on high-output days, which are common during chemotherapy.
