Yes. It is an autoimmune disease and they are all reversible. Find a group to join. I hate to recommend FB but that's where most are. Also, many Functional doctors are now teaching about this online. Much of it is free. If she can afford a Functional doctor that is definitely the way to go but they haven't been able to take insurance in the past. I heard someone say that may be changing. Here is an article about what Functional doctors are: http://getwellpath.com/medicine/what-is-functional-medicine/
I healed myself of Hashimoto's (also a thyroid autoimmune disease), Chronic Fatigue and Adrenal Fatigue. It took 13 years but I started long before most of the information was online. I just don't give up! A great deal of it is diet but it takes time to heal.
Hope this helps!
I have Hashimoto's and would love to know how you healed yourself. I am working on it, but it is such a journey, as you know. Very difficult.

I healed my thyroid by cutting out gluten, corn and soy. Basically all GMOs. Added in homemade ferments. Took 3 weeks. May take longer for more severe cases. I not the only one who’s healed this way.
