Immune health and autoimmune conditions
The immune system helps defend the body against infection. Autoimmune disease involves an immune response against the body's own tissues. Different autoimmune conditions need different assessments and treatments.
A useful distinction
Fibromyalgia is described by NIAMS as a chronic condition involving widespread pain, fatigue and sleep problems. It should not be presented here as proof of immune deficiency. A broad claim to boost immunity does not identify or treat a specific disease.
