When is ongoing tiredness a reason to see a doctor?
See a doctor if fatigue lasts more than a few weeks, does not improve with rest, or comes with weight loss, fever, or shortness of breath. Common causes include poor sleep, anemia, thyroid problems, depression, and medicine side effects. Energy supplements often rely on caffeine, which can mask the problem rather than fix it.
