Living with a hemicolectomy and managing a temporary ileostomy can be quite a journey. It involves understanding your body's new needs and finding ways to cope with changes in energy levels, hydration, and overall well-being. Here are some insights and advice that might help:

1. Recovery takes time. At 14 weeks post-operation, you're still in the healing phase. It's normal for recovery to take several months, so be patient with yourself.

2. Listen to your body. Engage in activities that your body can handle without overexerting yourself. If light activities leave you exhausted, it's important to pace yourself and rest as needed.

3. Stay hydrated. Managing fluid balance is crucial, especially since you've experienced dehydration. Try to drink a variety of fluids, not just water, to maintain hydration.

4. Monitor your health. Regular lab work can help keep track of your hydration status and overall recovery, ensuring that you're on the right path.

Remember, it's okay to take things slow and prioritize your health as you navigate this recovery period.
