Hi, thanks for using healthcare magic
can be intentional or unintentional. If you have not modified your diet or increased your level of activity in an attempt to lose weight then you need to see your doctor for an assessment.
Unintentional weight loss can be related to any chronic (longstanding) illness, kidney or heart disease
, cancer, infection, stress
, high levels of thyroid hormone.
Your doctor would take a full history and examine you for any conditions that could contribute to your weight loss.
The initial investigations would likely be a full blood count, ESR (checks for inflammation in the blood, stool samples for occult or hidden blood, thyroid function tests
, liver function tests and creatinine
levels to check the kidney.
I hope this helps
