Topic Explanation:
The discussion revolves around individuals experiencing weight gain following ileostomy surgery. The original poster, who had their ileostomy in December 2009, expresses concern about steady weight gain despite a low daily calorie intake and a change in diet that includes fewer fruits and vegetables, less meat, and more carbohydrates due to digestion issues. They also mention decreased activity levels and low energy. The poster is seeking insights and advice from others who might be experiencing similar issues post-surgery.

Extracted Advice and Helpful Insights:
1. Post-Surgery Metabolism Changes:
- It can take time for the body to adjust after ileostomy surgery, as the small intestine takes over the functions of the large intestine. This change can affect metabolism and may lead to weight gain as the body adapts to a new way of processing food.

2. Diet and Nutrition:
- Monitoring calorie intake and the types of food consumed is crucial. High carbohydrate diets are common post-surgery due to digestion ease, but they can contribute to weight gain.
- Incorporating suitable fruits and vegetables that do not cause blockages can help manage weight. Some individuals find that cooked vegetables and certain fruits like bananas are easier to digest.
- Drinking plenty of water and maintaining electrolyte balance is important.

3. Exercise and Activity:
- Increasing daily physical activity can help manage weight. Even light exercises like walking can be beneficial.
- It's important to find a balance that does not overly fatigue the individual but helps in increasing energy levels over time.

4. Emotional and Psychological Factors:
- Weight fluctuations can also be linked to emotional states such as depression or stress, which can affect eating habits and overall health.
- Support from healthcare professionals, including dietitians and therapists, can be beneficial in managing these aspects.

5. Ostomy Appliance Management:
- Weight gain can affect how an ostomy appliance fits and functions. Consulting with an enterostomal therapist (ET nurse) can help in adjusting the appliance to fit better as the body changes.

6. Community and Support:
- Engaging with community support groups, either online or in person, can provide emotional support and practical tips from others who have experienced similar challenges.

7. Long-term Management:
- Managing weight post-ileostomy is a long-term commitment that involves regular monitoring of diet, exercise, and lifestyle habits.
