Kyle Jenner’s hairstylist Jesus Guerrero’s cause of death has been revealed almost four months after his shock passing aged 34 

Although his family are still waiting for the autopsy results to come back, his sister has shed light on the health issues he suffered prior to his death 

His manner of death is listed as natural.

Guerrero’s death was announced by his family on social media on Feb. 23, shortly after he was in Dubai with Jennifer Lopez. Prior to his trip overseas, he had spent time with Jenner in Los Angeles.

‘He was diagnosed with gastritis months back, but it was never anything to get that bad. So we don’t know if that was a part of it,’ she told Us Weekly.

Gastritis, an inflammation of the stomach lining, can be the result of severe stress, medications, alcohol, diet, smoking, other illnesses, or even the knock-on effects of burns or major operations, among many potential factors.

Symptoms can include nausea and vomiting, pain or a burning feeling in the stomach, abdominal bleeding or appetite loss, according to Johns Hopkins. 

Gris shared that it ‘seems to be the case’ that her brother lost 20lbs leading up to his death, based on the ‘paperwork’ she has been able to read.

‘We think it could have been something with his stomach,’ she said, noting that his family knew ‘that he couldn’t eat without it being painful’ in his final days.

Guerrero was buried in his native Houston, Texas on Sunday over a month after his death, with both Jenner and Lopez in attendance, TMZ reports.

Gris had previously confirmed in a GoFundMe update on February 25 that the 27-year-old Kylie Cosmetics founder offered to cover his ‘funeral expenses and offering up all her help and support.’

‘She has told us anything we need. Jesus was family to her, and she was family to him,’ Gris told Us Weekly the same day.   

‘She has kept an open line. Anything we need, any questions we have, she has been there for us. She wants his memory to be honored and wants to do as much as she can so he gets the farewell he deserves.’

As for the $96K the family raised from an $80K goal, Guerrero said the GoFundMe money ‘will go toward the costs associated with securing his belongings home as well as other unexpected expenses to settle his assets.’

Guerrero’s client Katy Perry is currently hard at work rehearsing for her 83-date The Lifetimes Tour, kicking off April 23, and she was unable to attend his funeral 

Kylie called Jesus ‘a true artist’ whom she ‘loved so much’ in her tribute, gushing: ‘Jesus was more than my friend – he was a light in my life, a source of laughter, comfort, love, and unwavering support. I don’t know how I would have made it through the last almost decade without him by my side. He had a way of making even the heaviest days feel lighter.’ 

Gris also confirmed that the 55-year-old pop diva reached out and ‘talked us through everything that she could, along with others that were there. I am very grateful for everything she did [for him], to go to the doctor and not to work and to get rest’ during their recent work trip to Dubai.

‘Brokenhearted’ Jennifer wrote in her tribute that Guerrero ‘never demanded the spotlight’ because he never needed to make a sound to be recognized as ‘your heart and your talent did that as effortlessly as [your] artistry did.’

‘I know wherever you are there is beauty and light. And the beauty and light you left here will live on forever. Rest in peace, sweet angel,’ Lopez wrote.

Guerrero’s client Katy Perry is currently hard at work rehearsing for her 83-date The Lifetimes Tour, kicking off April 23, and she was unable to attend his funeral.

TMZ reported that the 40-year-old pop star ‘has been in touch with his family.’

Katy wrote in her tribute that she knew Jesus was ‘ok’ because he’s ‘in the light that you shined so brightly back here on Earth’ giving ‘the other Jesus a choppy feather or an octopus cut up there.’

‘It’s just us that are left with a dimmer world without you,’ Perry wrote.

Gris confirmed in a GoFundMe update on February 25 that the 27-year-old Kylie Cosmetics founder offered to cover his ‘funeral expenses and offering up all her help and support’ 

‘I found a quote that sums up the feelings I’ve had this past week that you’ve been gone: “Grief, I’ve learned, is really just love. It’s all the love you want to give, but cannot. All that unspent love gathers up in the corners of your eyes, the lump in your throat, and in that hollow part of your chest. Grief is just love with no place to go.”‘

Jesus had reportedly shed 20lbs and was complaining of chills and hot flashes leading up to his unexpected death.

‘We have been able to track every one of his steps, but we don’t know what got him sick or what was [the] sickness,’ Gris told Us.

‘It all happened suddenly and no one knows why. [He was in the hospital at the time of his passing] and that’s part of why there are so many unanswered questions because nothing they had done was able to prevent this from happening.’

Guerrero also handled the tresses of celebs like Jessica Alba, Casandra ‘Cassie’ Fine, Rosalía, Demi Moore, Charli xcx, Camila Cabello, Dua Lipa, LISA, Jessica Alba, and Shay Mitchell.
