Fatigue
Fatigue is a symptom, not a diagnosis. Get the cause identified.
Persistent fatigue deserves a proper work-up. Common reversible causes include iron or B12 deficiency, thyroid dysfunction, poor sleep, depression, and uncontrolled diabetes. A GP can arrange blood tests and review results in a follow-up consultation.
When to worry
Seek urgent medical care for any of the following:
- Fatigue with unintended weight loss
- Fatigue with night sweats or fever
- Shortness of breath on mild exertion
- Fatigue with depression, hopelessness, or loss of interest
Safe self-care
Reasonable first steps while you wait for or decide on a consultation:
- 7–9 hours of sleep on a consistent schedule
- Daylight exposure early in the day
- Regular movement — even a short daily walk
- Limit alcohol and late caffeine
- Balanced meals with protein, iron-rich foods, and vegetables
