Following on from Dynamo's revelation that Crohn's disease is the reason for his changing appearance, we've taken a look at some of the other chronic illnesses that many of the world's most popular stars suffer with. From the chronic pain condition that led Lady Gaga to cancel many of her live shows to Lena Dunham's experience with endometriosis, learn more about these celebrity health battles.
Dynamo – Crohn's disease:
Dynamo, real name Steven Frayne, shocked fans when he uploaded a candid photo of his swollen face – a side effect of the steroid treatment he has to manage his Crohn's disease. The magician was diagnosed with the condition when he was 15, and had to have half of his stomach removed when he was 17. He now follows a strict diet in order to better manage the pain, including banning gluten, dairy, fat and vegetables.
He is not the only famous face who struggles with Crohn's; former TOWIE star Samantha Faiers has also spoken openly about her experiences with the condition, which she was diagnosed with after falling ill during her appearance on Celebrity Big Brother.
