This article explores the causes, symptoms, and management options for long-term fatigue. It highlights how underlying health conditions like infections and nutritional deficiencies can trigger persistent tiredness, emphasizing the importance of early detection and symptom management.

Persistent tiredness, or fatigue, is a feeling of low energy that affects daily activities. It appears as overwhelming exhaustion, making even routine tasks feel difficult and reducing motivation. While occasional fatigue is normal, ongoing tiredness may indicate underlying medical problems. Conditions such as anemia, cancer, and nutritional issues often present fatigue as a symptom. Unexplained, long-lasting fatigue, known as chronic fatigue, can be linked to infections like Epstein-Barr virus or bacteria such as Mycoplasma, affecting immune response and cell health. Those in their 40s and 50s, mainly women, are more susceptible. Symptoms include memory problems, unrefreshing sleep, headaches, joint pain, and sore throats. Although no cure exists, treatment focuses on symptom relief and early diagnosis of potential underlying issues.
