A gastroenterologist has shared the worrying signs of a change in stool that could be a warning sign of something more sinister.

Noticing a change in bodily habits is important and if you notice worrying signs it's important to get checked out. Dr Joseph Salhab has urged people to take note of their bowel habits as it could be a tell-tale sign of bowel cancer. Despite the NHS stating that bowel cancer is mostly found among those in their 50s, Dr Joseph said it's also found in those in their 20s, 30s and 40s too, and told people to be their own "healthcare advocate".

Dr Joseph goes by the name @thestomachdoc online and he took to TikTok to inform people about the warning signs of bowel cancer. He stressed that one of the biggest signs is a change in stool behaviour. "You really need to be your own healthcare advocate and you need to try to recognise the warning signs of colon [another name for bowel] cancer to make sure you talk to your doctor about it," he said.

"New onset diarrhoea and new onset constipation, especially if you're straining now more than usual. The reason for this is that sometimes a large polyp or precancer in the colon, or even a colon cancer, can block your intestines," and stated that this can cause significant changes in the way you use the toilet. He further detailed: "If you notice that your stools are also narrow and thinner than normal, this is also something that needs to be investigated."

One TikToker shared her own experience of being diagnosed with colon cancer and said: "I was diagnosed with colon cancer at the age of 33, never knew anything about it. I am now 20 years cancer free. Thank you for your videos!" While another added: "At 32, I was diagnosed with stage III. A colonoscopy saved my life…..just turned 47!"

According to NHS, other symptoms of bowel cancer include needing to poo more or less frequently than normal, as well as noticing blood in your poo which "may look red or black". You should also make note of your weight, and if you notice you have lost weight, it can also signify changes in the bowel. The NHS also urge people to "not be embarrassed" about a change in toilet habits and to get themselves checked over if they show signs of bowel cancer for three weeks or longer.
