This topic is about preparing for a family gathering after having an ostomy surgery, with a focus on managing concerns about odor. The person is feeling anxious because their mother-in-law is worried about potential odors and has been sending suggestions for deodorizers. Here are some helpful tips and advice to ease these concerns:

1. Odor Reality vs. Paranoia
- A properly sealed ostomy appliance should not emit any odor. The main concern is leaks, which are rare if the appliance is secure.
- Often, the worry about odor is more significant than any actual smell. This is more about the mother-in-law's concern than a real issue.

2. Basic Preparation Routine
- Take a shower and change your pouch either on the morning of the event or the day before traveling.
- For a reliable seal, consider using a Hollister thin wafer over a 3M skin protector, as recommended by someone with 50 years of experience.

3. In-Pouch Deodorizers
- Use Hollister M9 drops, which are also available as a spray for room use and are commonly used in hospitals.
- Devrom chewable tablets can act as an internal deodorizer.
- Silica-gel packets for ostomies are available from Convatec or cheaper generic options online.

4. Toilet and Room Deodorizers
- Poo-Pourri can be sprayed into the toilet water before emptying the pouch; travel sizes are available.
- A drop of artificial vanilla can be added to the pouch after emptying.
- Small room sprays from Bath & Body Works or similar brands can be used, and a scented dryer sheet can be taped to the pouch if desired.
- Flush the toilet immediately when output hits the water and again after wiping. If possible, pour a little bleach into the toilet.

5. Food and Timing Tips
- Avoid foods that can increase odor or gas, such as onions, garlic, beans, strong cheeses, fish, and high-FODMAP items, the day before the event.
- Eating marshmallows can help slow output for a few hours.

6. Travel and Backup Kit
- Bring spare pouches, scented disposal bags, small trash bags, wet wipes, and a travel-sized room spray.
- Double-bag used appliances before disposing of them.

7. Mindset and Family Dynamics
- Set boundaries and ask your husband to address any comments from his mother or to kindly educate her privately.
- Remember that everyone deals with odors, and it doesn't define you.
- If a leak happens, you will likely notice it before anyone else does. Handle it discreetly and continue enjoying the gathering.

8. Extra Product Notes and Cautions
- Be cautious with certain products like Zepbound, which caused a blockage for one person.
- There is no feedback provided for Wacovy "fat shot."

These tips should help you feel more confident and prepared for your family gathering.
