Kris Jenner’s sister Karen Houghton’s cause of death revealed

Kris Jenner’s sister Karen Houghton’s cause of death has been revealed nearly a month after she died at age 65.

According to a death certificate obtained by TMZ, Houghton’s official cause of death was listed as cardiac arrest and sudden cardiac arrhythmia with Type 2 diabetes listed as a secondary underlying cause.

The documents also state Houghton had been previously diagnosed with bipolar disorder and was cremated following her March 19 death.

Jenner, 68, announced her sister’s “unexpected” death on Instagram last month.

“It is with the heaviest heart and deepest sadness that I share that my sister Karen passed away yesterday unexpectedly,” she captioned a carousel of throwback pics of Houghton with her and other relatives.

The “Kardashians” star said her “heart aches” for her mother, Mary Jo Campbell, and Houghton’s daughter, Natalie.

“Karen was beautiful inside and out,” Jenner added. “She was the sweetest, kindest, the most sensitive and vulnerable and so so funny. She always felt grateful and thankful for her life and treasured her family and friends and especially her beautiful daughter.”

The mom of six said she cherishes “every single memory” they have together.

“Karen’s passing is a reminder that life is so short and precious and tomorrow is never promised. We must tell those we cherish how much we love them. I love you my beautiful sister,” she concluded.

Jenner’s daughter Kim Kardashian honored her late aunt on social media after her death.

“🕊️I love you so much auntie Karen🕊️,” the Skims founder, 43, captioned a series of throwback pics on March 21.

While not much is known about Jenner and Houghton’s relationship, it seems that they had been estranged at one point.

In April 2014, Houghton reportedly asked her FaceBook friends to “pray” for her “crazy” older sister because “she needs it.”

”Shes as [sic] nutcase. She doesn’t need prayers she needs sky vodka hahaha hahaha hahaha,” the mom of one added, per RadarOnline.

Houghton also told the outlet that Jenner would not return her phone calls.

“And it hurts me. I don’t care how much money you have or who you are, you’re my sister. I’m not afraid of her. … I can’t get to her anymore. But I guess it’s the money,” she said.

It’s unclear if the siblings mended their relationship before Houghton’s death.

The sisters were last seen posing with other relatives during Christmas of 2019.
