An NHS doctor has warned people about three health signs that they should do something about immediately if spotted.
Dr Karan Rajan, an NHS surgeon, uses social media platform TikTok to explain medical situations to millions of viewers.
The first thing he said to be aware of concerns our eyes and so-called "floaters" in your vision.

Another thing to be aware of comes with eating.
The doctor added: "If you start feeling full after eating small amounts or you notice a change in your appetite over several weeks for no apparent reason then go and get it checked out."
The third is a more physical symptom to look out for.
