I've just watched Dr in the House on UK tv.
The doctor treated a woman diagnosed with the above conditions and a prediabetic woman and her diabetic mother who had markers for heart attack. The ME lady was taking a cocktail of medications many of which I've read about on this site. He advised:-
Cut out dairy and processed foods and sugar in order to reduce inflammation.
Avoid tv and phones at night in bedroom to avoid 'blue' light. Wear 'amber' glasses to reduce 'blue' light. This is to improve sleep quality. Do yoga before bed.
Walk in sunlight for vitamin D. The lady was lacking B12. She was on 17 tablets per day / reduced by half in 6 weeks. Plus they all lost weight. Prediabetic ladies reduced sugar levels from 17 to 4.
Basically same advice to all three women. Improve gut bacteria, exercise and have time to relax ie yoga before bed.
Hope this helps
