PERSISTENT TIREDNESS WITH MANY POSSIBLE CAUSES

Fatigue / Weakness

Q: When should I see a doctor for fatigue?

See a doctor if fatigue is persistent (more than 2 to 4 weeks), is significantly affecting daily life, is associated with red-flag features such as weight loss, fever, lymph node enlargement or neurological symptoms, or is unexplained by lifestyle factors.

Q: What blood tests are usually done for fatigue?

Initial workup typically includes complete blood count, thyroid function, kidney and liver function, iron studies, vitamin B12, vitamin D, blood sugar and inflammatory markers. Further tests are guided by initial findings and clinical features.

Q: Can fatigue be due to mental health?

Yes. Depression, anxiety and chronic stress are very common causes of persistent fatigue, often together with physical contributors. Mental health assessment is an important part of fatigue evaluation, and addressing mental health needs significantly improves energy.

ABOUT THIS CONDITION

What is Fatigue and Weakness

Fatigue is a feeling of persistent tiredness, exhaustion or lack of energy that is not relieved by rest, while weakness refers to reduced muscle strength. Both are very common complaints with a wide range of possible causes. Common medical causes include anaemia, vitamin and mineral deficiencies (particularly iron, vitamin B12, vitamin D), thyroid disorders, diabetes, kidney and liver disease, heart and lung conditions, infections (including viral illness and tuberculosis), inflammatory conditions, sleep disorders (particularly sleep apnea), and certain medications. Mental health causes including depression, anxiety and chronic stress are also very common contributors. Lifestyle factors such as poor sleep, sedentary lifestyle, dehydration, inadequate diet and excessive caffeine or alcohol play important roles. In some patients, fatigue persists despite thorough evaluation — termed chronic fatigue syndrome or similar conditions. Diagnosis involves detailed history, examination and targeted blood tests, with further investigation guided by initial findings. Treatment is cause-specific. Dr. Patnam Pravallika Reddy provides comprehensive fatigue evaluation and care at Lux Hospitals, Hyderabad.
