Six key facts about Michael Klim, drawn from verified sources:

What is Michael Klim diagnosed with?

What is CIDP?

Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) is a neurological disorder in which the immune system attacks the protective covering of nerves, leading to weakness and impaired function.

Klim told People that his health “began to deteriorate drastically” and that he experienced severe muscle weakness, especially in his legs and feet, leaving him unable to stand properly. He said: “My condition mainly affects my legs and feet.”

What treatments has he tried?

• IVIG (intravenous immunoglobulin) therapy
• Steroid treatment
