multiple auto immune issues-? LDN

[mobadminton]

I'm new here and really joined to try and get info for my 28 year old son.He was diagnosed with psoriasis/coeliac disease as a baby/child.Diagnosed with Type 1 diabetes aged 23 and recently diagnosed with hyperthyroidism(not diagnosed yet, but likely to be autoimmune I would think) I came across this site when I was researching LDN. Would really appreciate anyone who has used this to post and let me know whether it had any positive/negative or even no, effects. I myself have Hashimotos, Dupytrens contracture and various other auto immune issues over my 68 years but none of them really life changing.
