Medical experts warn of persistent fatigue as a potential health indicator

Medical experts are highlighting the distinction between normal tiredness and persistent fatigue that may indicate underlying health issues. One significant cause of unrelenting lethargy is vitamin D deficiency, which is often exacerbated by modern urban lifestyles, indoor work environments, air pollution, and skin pigmentation. Symptoms of such a deficiency can include muscle weakness, aches, cramps, and bone pain.

Specialists in internal medicine, endocrinology, and nuclear medicine note that fatigue becomes a medical concern when it persists despite adequate rest and begins to interfere with daily life. While common causes include stress, poor sleep, or post-COVID exhaustion, doctors emphasize that chronic fatigue requires clinical evaluation to rule out various medical conditions and deficiencies.
