ICD-Code G93.39: Chronic fatigue syndrome, unspecified

You have a condition that causes various symptoms, including severe, persistent fatigue.

Severe, persistent fatigue can occur, for example, after viruses or in the context of other underlying diseases. The exact cause has not yet been fully understood.

The fatigue experienced can severely impact daily life. Even with rest and reduced activity, the exhaustion does not generally show any lasting improvement. Typically, additional symptoms also occur. These include sleep disturbances, concentration difficulties, or pain.

Typically, the condition worsens with exertion. Symptoms can deteriorate following both physical and mental effort. Even minimal exertion is generally sufficient to trigger this. The deterioration occurs either immediately or after a delay.

  • G: Confirmed diagnosis
  • V: Tentative diagnosis
  • Z: Condition after
  • A: Excluded diagnosis
  • L: Left
  • R: Right
