<h1>Hospital warns persistent fatigue may signal serious blood disorders requiring immediate medical evaluation and testing</h1> A hospital in Tamil Nadu warns that persistent fatigue, often dismissed as normal tiredness, may indicate underlying blood disorders requiring medical attention. The facility emphasizes that chronic exhaustion unrelieved by rest could signal conditions including iron-deficiency anemia, vitamin deficiencies, thalassemia, aplastic anemia, or blood cancers. Additional warning signs include pale skin, shortness of breath, dizziness, frequent infections, and unexplained bruising. Medical experts stress that fatigue lasting over two to three weeks warrants evaluation, as early detection through basic blood tests can prevent complications and improve treatment outcomes.
