Unintentional weight loss can have many different causes.
It might be caused by a stressful event like a divorce, losing a job, or the death of a loved one. It can also be caused by a health condition or a combination of things.
Sometimes weight loss and loss of appetite can be caused by cancer. It's important to get it checked if you're losing weight without trying.
- you keep losing weight without changing your diet or exercise routine
It's important to see a GP as soon as possible if you have weight loss and other symptoms. The earlier the cause is found, the sooner it can be treated.
Treatment for unintentional weight loss depends on what's causing it.
A GP will ask about your health and may arrange some tests or scans.
