Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice. Loss of appetite accompanied with
weight loss is actually worth investigating.
It would be important to know for how long this has been going on, any accompanied symptoms and signs like fever, enlarged
lymph nodes or pain. Giving drugs that boost appetite is good, but understanding the underlying cause of the symptoms is more important.
I suggest you consult your
primary care physician first for a proper evaluation and management. Blood tests like complete blood tests, active search of an infection, exclusion of tumours or other metabolic diseases like
diabetes mellitus is my advice.
Thanks and hope this helps as I suggest you
consult a pediatrician.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Luchuo Engelbert Bain, MD.
