This topic is about finding ways to safely enjoy swimming or aquafit when dealing with a large parastomal hernia, along with tips for concealing the hernia and ideas for weight loss. The person in question has limited mobility and heart disease, so they are seeking advice on how to manage these activities safely and comfortably.

Here are some helpful insights and advice:

1. **Concealment and Clothing**
- Consider wearing an ostomy or hernia support belt, including those made from neoprene for water use, under your swimsuit.
- Opt for skirted swimsuits, swim-dresses a couple of sizes larger, or swim outfit separates from brands like Lands’ End. These can help hide the bulge with their loose fabric.
- Swimming shorts paired with a light T-shirt can also help disguise the area.
- Participating in evening or "moonlight" aquafit sessions might help reduce self-consciousness.

2. **Safety and Medical Clearance**
- It's important to consult with a doctor or stoma nurse before starting any new exercise routine. They can provide guidance on managing load, water resistance, and choosing the right support garments.
- Many people with smaller hernias have successfully participated in swimming and aquafit without issues when using a support belt.
- Gentle water exercises are often recommended for those with limited mobility or heart issues, as they can lead to less pain and improved overall function.

3. **Exercise and Lifestyle Motivation**
- Joining regular aquafit classes can help build a supportive social network, as classmates often become encouraging friends.
- Pilates is suggested as another gentle exercise option that can help strengthen the core.

4. **Weight-Loss Programs**
- The person is currently using SlimFast meal-replacement shakes, though they experience gas as a side effect.
- The Isagenix nutrition and cleansing system has been beneficial for some, helping with weight loss and reducing abdominal fat. It might be worth looking into if available locally.

5. **General Encouragement**
- Many people with ostomies lead full lives, including traveling and engaging in DIY projects, after adjusting to their stoma and hernia. Staying active, even at a slower pace, is both achievable and beneficial.
