Fatiguerelated

Fatiguerelated is a descriptor used in medical and research contexts to denote symptoms, conditions, or outcomes attributable to fatigue. It covers phenomena where energy depletion or reduced capacity influences function, well-being, or health status.

Fatigue can be physical, cognitive, or emotional. Physical fatigue refers to decreased strength and endurance; cognitive fatigue to impaired attention, slowed processing, and poorer decision-making; emotional fatigue to reduced motivation and mood changes. These domains may co-occur or appear independently.

Causes are diverse and include insufficient or disrupted sleep, circadian misalignment, chronic illnesses (such as anemia, thyroid disorders, diabetes, cancer with treatment), infections, chronic pain, obesity, and mental health conditions like depression or anxiety. Medications, substances, and lifestyle factors can contribute.

The impact of fatigue-related conditions ranges from reduced work or academic performance to impaired driving safety and lower quality of life. Fatigue can also complicate clinical management by masking other symptoms.

Assessment often uses validated scales (for example, the Fatigue Severity Scale or Brief Fatigue Inventory) alongside clinical evaluation to identify contributing factors. Management focuses on treating underlying causes, improving sleep and daytime activity, energy pacing, and addressing psychological or social factors.

In research and practice, fatigue-related terminology helps summarize outcomes linked to energy depletion, but precise definitions and measurement remain areas of standardization.
