Liam's Worthing Half Marathon I'm raising money for the Addison's Disease Self-Help Group so that they can continue to support people with Addison's and adrenal insufficiency. Addison’s is a rare endocrine condition where the adrenal glands do not produce enough steroid hormones and can be life-threatening. It affects approximately 1 in 10,000 people, meaning an estimated 300 - 350 new cases are diagnosed each year across the UK, this makes it roughly 300 times rarer than diabetes.
