The 24-year-old 'Fancy' hitmaker mentioned about Temporomandibular joint dysfunction (TMJ) on Twitter on New Year's Eve, while sharing her plans for 2015, reported Aceshowbiz.
"Last month I was diagnosed with TMJ which isn't the best," she wrote after confirming that she would start working on her second album next week.
"I'm gonna make more of an effort to take care of myself in 2015, stay away from all the drama & hopefully not have any (flare ups)," she added.
"I don't think western medicine all the way acknowledges what a huge toll mental stress takes on our bodies. But I do believe it is a factor.
"Anyhow I don't think it will ever prevent me from doing anything I want to but it has made me realise it's important to look after yourself. So that's my little update and message! Look after your body and mind in the new year, be safe and enjoy it all!" she concluded.
