It was only in September that the world found out about Selena Gomez's kidney transplant. Selena has suffered with Lupus disease since she was diagnosed in 2014. For those of you who may not know, lupus is a fatal inflammatory disease that results in the body's immune system attacking its own tissues and organs.\nLupus can affect many aspects of one's health, from joints and skin to kidneys, blood cells, your brain, heart and lungs. Anxiety, panic attacks and depression are also side effects of lupus, which explains why Selena has sought treatment for mental health disorders in the past.\nA post shared by Selena Gomez (@selenagomez) on Sep 14, 2017 at 3:07am PDT\nThis past summer, Selena admitted in an emotional Instagram post, that lupus had caused her kidneys to fail. "I am very aware some of my fans had noticed I was laying low for part of the summer and questioning why I wasn’t promoting my new music...I found out I needed to get a kidney transplant due to my Lupus and was recovering. It was what I needed to do for my overall health."\n"I want to publicly thank my family and incredible team of doctors for everything they have done for me prior to and post-surgery. And finally, there aren’t words to describe how I can possibly thank my beautiful friend Francia Raisa. She gave me the ultimate gift and sacrifice by donating her kidney to me. I am incredibly blessed. I love you so much."\nFrancia and Selena sat down with Savannah Guthrie from Today to discuss the surgery for the first time.
