After my last I took another look at what you were discussing. Vitamin A is a necessary nutrient for the kidneys but kidney disease can turn the situation around so that the vitamin A aggravates the disease. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5351338/ In early stages of disease retinoic acid and retinoids help to reduce the severity of not only kidney conditions but many different health issues throughout the body. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4370041/ Think of all of the damage, resulting from toxic substances being eliminated by both the liver and kidneys, and the role of the retinoids in enabling repair. https://pubmed.ncbi.nlm.nih.gov/37331524/ One of the bigger problems is that cadmium actually enters the cells in the kidneys, with a half life of up to thirty years, making things even worse. That's what I have been looking at in terms of my own condition. I would consider it possible that the issues with vitamin A may relate to the iron deficiency found in kidney disease. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7062209/I am trying to get my head around this Alopecia, not everyone has this with ME/CFS EDS Hair loss, countless take fish oils, multi vitamins minerals & most stop them as they become bothersome. There are a few good Groups on Copper on Facebook & one is dead against any blood tests for copper saying they are useless they do not believe in ranges or toxicity they mention vitamin A as well they take this & iron.
There is an interesting paper I read & not all have a kidney that is enlarged but my left one is & so was hers she was a 21 year old Medical student she became sick she tested positive for the latent TB form & negative on the other one. She was treated but her illness did not go away. She had an untrasound they said her kidney was enlarged & it took her more years to have the proper venous scans.
They kept telling her that her kidney was fine but it was not her kidney it was the vein one inch higher above she was finally diagnosed with Nutcracker Syndrome but she underwent the first of its kind in the UK an auto-transportation surgery.
They did not want do this so she told the Team she would go to the USA or France so they gave in & said we will do this. She felt well in the post-op recovery room she knew this was why she was so ill & she recovered but several months later she developed Stenosis of a renal vein & had to undergo another Surgery.
There are other tests she did Gold standard ones urine collections she wrote about on her Published paper. Patient/Medical Student/GP/Author Dr. Tamara Keith She is now a partner GP in Cambridgeshire. They told me I had a Dromedary Hump a large lop sided kidney like a single Camel hump on ultrasound but never did the venous venography testing she underwent. She is also on Twitter...
