Katie's ongoing transformations have raised questions about her relationship with body image, and Katie herself has hinted at the possibility of having body dysmorphia - a mental health condition where an individual obsessively worries about their appearance.
Speaking on Radio 4's Women's Hour in March last year, Katie explained why she has had so many procedures over the years: "I don't have surgery to look younger.
Katie's friends have reportedly expressed concerns that the former glamour model is putting herself in "serious danger" with her continued cosmetic surgery.
The insider revealed : "Katie not only wants the biggest lips and boobs in the business but, in a shocking revelation made at The Glamour Awards, she also wants the smallest waist, setting her sights on 22 inches.
While her loved ones have raised concerns over the years, Katie says she sometimes regrets not taking full advantage of the free treatments offered to her.
