Hi there..
Thanks for writing in.
The possiblities I can think of are
anaemia, low blood sugars, low blood pressure,
thyroid disorders ,
depression, etc.
Also do find out if she has any problems at school. Is she worried or anxious about certain things at school etc. Talk to her.
I would advise you to visit a physician and get the following done:
Get her blood pressure checked.
Investigations like
Hemoglobin, TSH, Random blood sugar, Vitamin D ,
Vitamin B12, and serum electrolytes.
If everything is Ok...then sign up for yoga classes which might help.
In the meantime, let her eat well balanced nutritious meals.
Drink 8-10 glasses of water a day.
Hope your daughter feels better soon.
Have a good day
Regards,
Dr. Divya Kuttikrishnan
