Fatigue is present for months, sometimes years before a serious condition is diagnosed and more often than not, is an indication of an underlying abnormality.
Fatigue may be caused by multiple reasons:
-poor quality sleep or lack of sleep
-poor eating habits
-alcohol and/or caffeine consumption before bedtime
-hormonal problems (low estrogen, low progesterone, abnormal thyroid function, POTS etc.)
-medications (stimulants that interfere with sleep etc.)
It is very important to address the root cause of fatigue, rather than just treat the symptom.
