Dr James O'Donovan has told his 1.4 million YouTube subscribers that splinter haemorrhages in nails could be a sign of a cardiovascular condition - and to seek medical advice if you have them
Dr James O'Donovan, a doctor and YouTuber who also serves as a WHO and Research Director for a global health non-profit, has warned that an unusual sign on your nails could indicate heart disease . In a video discussing the 12 signs of heart disease visible in your skin and nails, he told his followers to look out for splinter haemorrhages.
On white skin, they can appear as red or purple streaks, while on black skin they might look brown or black. Dr O'Donovan added: "Now, most commonly they can be caused by injuries, but if you don't remember hurting your nail then it could be a potential sign of heart disease or other conditions, so it's worth seeing your doctor if this is the case.
If you notice any unusual signs or symptoms on your fingers, it's advised to seek advice from the NHS or another healthcare professional. Dr O'Donovan isn't the only expert highlighting potential heart disease symptoms during winter, reports Surrey Live. He told the Daily Express: "When outside, breathing in through your nose helps to warm up the air, as does wearing a mask or loosely wrapping a scarf around your nose and mouth if it is comfortable to do so. Wearing thermals and layers of thinner clothing instead of one thick layer can keep you warmer too."
