Selena Gomez reveals she had a kidney transplant over the summer via Instagram

Selena Gomez was absent from headlines most of the summer and this morning she took to Instagram to reveal why.

The 25-year-old singer had a kidney transplant.

I’m 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, which I was extremely proud of. So 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. I honestly look forward to sharing with you, soon my journey through these past several months as I have always wanted to do with you. Until then 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 sis. Lupus continues to be very misunderstood but progress is being made.

Gomez has had to lay low before. She was diagnosed with Lupus in 2013 and did a round of chemotherapy to combat the autoimmune disease. Last year she took time off to combat the anxiety and depression that comes with having a life-altering disease.

Kidney problems in people diagnosed with Lupus are fairly common - not from the disease itself, but from the medications used to treat the symptoms, according to Lupus.org. There are other complications from Lupus that can damage the kidneys as well as other major organs in the body, such as the heart and lungs.

According to Kidney.org, Lupus does not usually recur in the transplanted kidney. However, the kidney itself is only a temporary fix as they last at the very most 15 years. Living donor organs last longer than deceased donors, particularly in kidneys. Find out how to become a living donor at UNOS.com.
