Yes, you can use water fasting to aid an autoimmunity disease. But what will be most impactful coupled with fasting is adopting a raw food diet. If you combine the two you may be able to revere your condition. Look up some raw food channels on youtube and if you need more concise information I have consultation available. https://ahealthyalternative.org/consultations/

Thanks Chris, greatly appreciated!  I'm on day 4 of my water fast and I've lost 10.1lbs. It was a fairly easy transition for me since I'm more of an alkaline vegan and did intermittent fasting prior to the fast.
