What is a chronic fatigue evaluation?
Fatigue is one of the most common reasons adults see a doctor. Most of the time it reflects lifestyle factors such as long working hours, poor sleep or stress, but it can also be the first sign of a medical condition. A chronic fatigue evaluation systematically checks for those conditions so that treatable causes are not missed and you get a clear plan rather than a vague reassurance.
When fatigue lasts six months or longer, worsens markedly after physical or mental effort, and is accompanied by unrefreshing sleep and memory or concentration problems, doctors may consider myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), a diagnosis made after other causes are ruled out.
Symptoms and when to see a doctor
- Tiredness on most days for more than a few weeks that rest does not fix
- Fatigue with weight loss, fever, night sweats or swollen glands
- Loud snoring, gasping in sleep, or daytime sleepiness
- Low mood, loss of interest, or anxiety
- Exhaustion lingering after COVID-19 or another infection
Fatigue with chest pain, fainting or severe breathlessness needs urgent assessment; call 119 if symptoms are sudden or severe.
What happens at the clinic
- Detailed history: sleep, work hours, alcohol, caffeine, diet, periods, mood, medicines and recent infections.
- Examination: blood pressure, weight, thyroid, lymph nodes, heart and lungs.
- Blood and urine tests: complete blood count, ferritin, thyroid function, glucose or HbA1c, liver and kidney function, electrolytes, inflammation markers, and sometimes vitamin D, B12 or hormone levels.
- Screening questionnaires: short tools for depression, anxiety and sleepiness.
- Review and plan: results are explained, and further tests such as a sleep study or referrals are arranged if needed.
Treatment outlook
When a cause such as iron deficiency, an underactive thyroid or sleep apnea is found, treatment usually brings steady improvement. If tests are normal, the doctor focuses on sleep habits, gradual activity, stress and mood. For suspected ME/CFS, careful pacing of activity is preferred over pushing through, which can cause crashes.
Risks and limitations
Blood tests are low-risk. The main limitation is that normal results do not mean the fatigue is imaginary. Be cautious of clinics recommending long courses of expensive supplements or drips without a diagnosis.
Choosing a clinic for fatigue evaluation in Seomyeon
- Choose an internal medicine or family medicine specialist who takes a full history, not a fixed package.
- Ask which tests are included and why each is chosen for you.
- Check whether the clinic can screen for sleep apnea or refer for a sleep study.
- Ask how mood and stress are assessed and whether mental health referral is available.
- Request a follow-up appointment to review results in person.

Frequently asked questions
What blood tests check for fatigue?
Common tests include a complete blood count, ferritin, thyroid function, blood sugar or HbA1c, liver and kidney function, electrolytes and inflammation markers. Vitamin D, B12 and hormone tests are added depending on your symptoms.
When should I worry about being tired all the time?
See a doctor if tiredness lasts more than a few weeks despite rest, or comes with weight loss, fever, night sweats, breathlessness, low mood or heavy snoring. Sudden exhaustion with chest pain or fainting needs urgent care.
Is chronic fatigue syndrome diagnosed in Korea?
Yes. Doctors may diagnose ME/CFS when severe fatigue lasts six months or more with post-exertional symptom worsening and other causes have been excluded. A thorough evaluation for other conditions comes first.
Will an IV drip fix my fatigue?
A drip can help if you are dehydrated or deficient, but it does not treat most causes of chronic fatigue. It is better to find the cause first through history, examination and tests.
Can long COVID cause fatigue?
Yes. Persistent fatigue, breathlessness and concentration problems can follow COVID-19 and other infections. A doctor can rule out other causes and advise on paced return to activity.
