Fatigue
Fatigue is one of the least specific symptoms in medicine — blood sugar swings, thyroid changes, low iron or B12, poor sleep, and chronic stress can all produce the same complaint, which is why it benefits from a structured look rather than a single fix.
Possible Related Conditions
Fatigue can show up across several different conditions. These are worth exploring, not a diagnosis of what you have.

Assessment
This is general guidance on how fatigue is typically assessed — not a diagnosis. Only a doctor examining you and reviewing your full history can determine what's actually going on.
A reasonable starting point is usually a panel covering thyroid function, iron studies, vitamin B12, and fasting glucose or HbA1c, reviewed alongside your sleep, stress, and activity patterns.
Consider seeing a doctor sooner if:
- Fatigue is severe, sudden, or unrelenting
- It comes with unexplained weight change
- You notice shortness of breath or chest discomfort
- It doesn't improve after 2-3 weeks of adequate sleep
Consultation
The most reliable next step is a consultation where your history, symptoms, and any relevant tests can be reviewed together.
