What causes chronic fatigue?

The exact cause of chronic fatigue isn’t fully understood, and it’s likely that several factors are at play. For some, it may follow a viral infection like Epstein-Barr or COVID-19. For others, it could be related to immune system issues, hormonal imbalances (like thyroid dysfunction), sleep disorders, or psychological stress. Interestingly, many patients—especially women—experience chronic fatigue in conjunction with hormonal changes, such as those during perimenopause or menopause. It's important to look at each person’s case individually to identify possible triggers.
