The exact cause of Chronic Fatigue Syndrome / M.E. (ME/CFS) remains unknown, though current evidence suggests it is a complex, multi-system disease likely triggered by a combination of biological, environmental, and genetic factors.
While researchers have not identified a single "smoking gun" for Chronic Fatigue Syndrome / M.E., the leading hypothesis is that the disease arises when a susceptible individual experiences an external trigger that causes their immune system to become dysregulated. Think of the body like a home security system; in ME/CFS, it is as if the alarm has been triggered and cannot be turned off, leading to persistent, systemic exhaustion.
It is crucial to distinguish between a cause (the direct mechanism that creates the disease) and a risk factor (a trait that makes someone more likely to develop it). At this stage, we are still working to categorize many variables, such as hormonal imbalances or autonomic nervous system dysfunction, as either contributing causes or downstream effects of the primary pathology of Chronic Fatigue Syndrome / M.E.
