Thank you for your query.
It is very difficult to give a possible reason to the problems that you have mentioned. However, the following questions need to be answered:
1. Over how much time has your niece lost weight?
2. How much weight loss
has been there?
3. What about her appetie and diet? Has it been reducing?
4. Any history of fever?
5. Any history of vomiting
6. Any change in her behaviour lately?
7. Any distension of abdomen?
8. Why was an endocrinologist
I hope you will appreciate the importance of these queries. It would be better to discuss the problem with the treating doctor who may throw more light on the possible cause of the problem with your niece.
I hope I have answered your query to your satisfaction.
Wishing your niece an early recovery.
