This article explores the main causes of persistent fatigue, including infections, hormonal imbalances, and stress. It highlights key symptoms to watch for and effective management strategies to improve well-being. Understanding these factors can help individuals seek proper diagnosis and adopt lifestyle changes for better health.

Prolonged tiredness despite adequate rest can signal underlying health concerns. While daily fatigue is normal, persistent exhaustion may be a sign of chronic fatigue syndrome (CFS), also known as Systemic Exertion Intolerance Disease (SEID). This condition is marked by relentless fatigue without clear causes, often linked to stress, infections, immune weakness, hormonal imbalances, genetics, allergies, or environmental factors.

Many infections, especially viral, can trigger or worsen fatigue. Sometimes, fatigue indicates a deeper health issue or immune response. Symptoms such as headaches, body aches, sleep issues, concentration difficulties, and swollen lymph nodes should not be ignored.

Diagnosis involves broad blood tests and imaging to exclude other conditions. Since a cure is unavailable, treatment aims at symptom management and lifestyle improvements through sleep hygiene, gentle exercise, stress reduction, and proper nutrition. These strategies, combined with medical advice, help improve quality of life and overall vitality.
