Thank you for asking Healthcare majic.
My name is Dr Ehsan Ullah &
I have gone through your query.
One of the most common aspect in today's life is
Stress...
whether
work related stress which can be
either
Work load which may have increased over the period of time
factors of mental stress related to workplace
another aspect is
Emotional stress
any of these factors directly and indirectly affects the Life style
in the form of
-Lack of sleep / disturbed sleep
-Mood variations
-Loss of appetite or disturbed eating pattern
just have a look at these in the first instance and these things are modifiable most of the time.
another aspect is lack of energy ,
fatigue and exhaustion due to some pathology , commonly due to
Anemia ...and some other such condition.. for those you need to visit your GP for clinical assessment and Lab work...
I would recommend that you should look first in the Life style changes and if there you find some aspect which is modifiable and can improve your sleep, diet and stress related issue so hopefully you will get much better without treatment.
in Case not, then you should consult your GP for clinical work up.
Hope this may help you. Let me know if anything not clear.
Thanks.
