My wife, Katherine White, who has died aged 63 of an aortic dissection, was a campaigner for people with Addison’s disease, a rare endocrine condition where the adrenal glands cease to function and the body no longer produces enough essential steroid hormones.
Following her own diagnosis with the condition in 1998, Katherine devoted much of the rest of her life to deepening her understanding of Addison’s and to supporting people’s management of it.
