Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice. White spots
may indicate vitamin deficiency
. And drastic reduction in weight is not advisable. So let her once consult general physician and get examined. If her calorie intake is less than required, she has to increase that. Vitamin and minerals supplementation is needed.
Hope I have answered your query. Let me know if I can assist you further.
