HI, thanks for using healthcare magic
Unintentional weight loss
may not be due to any serious conditions but it should always be investigated.
Unintentional weight loss of 10 pounds in 1 month is significant.
The possible causes are: (1) loss of appetite
(2) persistent vomiting
(3)side effect of medication
(5)endocrine diseases such as hyperthyroidism
(8)systemic disease such as liver disease, kidney
It would best to go to your doctor for an assessment which includes physical examination , blood tests (such as full blood count, liver function tests, kidney tests, thyroid function test) and possibly imaging.
I hope this helps
