Singer Jessie J says she doesn't like to take antibiotics as she tries to beat illnesses herself with her lifestyle choices.

The singer shared her way to cope with illness while talking to Women's Health magazine, reports femalefirst.co.uk.

"I'm healthy because I have to look after myself. I like to feel everything I feel based on purity. So, if I'm sick, I won't just take antibiotics, I will try to get through it myself," Jessie said.

The 27-year-old has lived with wolff-parkinson-white syndrome, a heart condition that causes irregular heartbeat, since she was 9 and last year she had to cancel a string of Australian tour dates after a health scare related to the condition.
