Hi there, thanks for asking. The reasons for feeling exhausted are quite diverse. In some cases it is due to thyroid
low functioning or other endocrine problems. It may be related anemia
. It could also be related dysthymia
which is a chronic feeling of low mood. With less probability, it could be related to liver or renal problems. It could be fibromyalgia
if you have tender points around your elbow or on the sternum
. It is appropriate to ask your doctor to investigate about all the possibilities. If no abnormality is found in the laboratory investigations, you can take advantage of some talk sessions for breaking the chain of events which bring for you exhaustion. I wish a good health for you.
