In this Fasting Q&A episode, Megan and Nadia answer your fasting questions:

1. Last year I had a hysterectomy, but kept my ovaries. At the time, I was in peri-menopause. How will this impact fasting and should I do anything differently? [02:27]

2. Do vitamins or pain-relief tablets break a fast? [08:44]

3. If female hormones are so important for women and help us maintain weight during reproductive age, what do you think about the impact of birth control pills on metabolism? [13:41]

4. We often travel for an extended amount of time to 4000m. I am not sure if fasting 48-72 hrs would put too much stress on the body since high altitude is a big change for the body anyway? [20:58]
