10 Warning Signs That Your Immune System Is Malfunctioning

10. Persistent and Overwhelming Fatigue
Fatigue caused by the immune system is different from being tired after a hard day's work; this exhaustion does not improve even with hours of sleep and rest. When the immune system is constantly on high alert or attacking (even mistakenly), it devours the body's vital energy. This state, often seen in diseases like Multiple Sclerosis (MS), Lupus, or Chronic Fatigue Syndrome, shows that the body's energy resources are being wasted on futile internal battles, preventing the individual from performing daily activities.
