Nikki Grahame's sudden death has sparked an internal investigation at the Dorset hospital where she had been receiving treatment for anorexia.
The Big Brother star, 38, was discharged from Dorset County Hospital in Dorchester on 9 April after three weeks of treatment and her body was found at her London home the following day.
A spokeswoman for the Dorset County Hospital NHS Foundation Trust confirmed to The Sun that hospital officials would be conducting a full investigation into Nikki's death.
"Staff at the Trust were deeply saddened to learn of the death of Miss Grahame, and our thoughts are with the family and friends of Miss Grahame at this very difficult time," the spokeswoman said. "A full internal investigation into the circumstances of Miss Grahame's death is currently underway. This is in line with standard procedures following any sudden death.
"All information and findings arising from this investigation will be shared confidentially with Miss Grahame's family, and thereafter with the Coroner as part of any Coronial process. The Trust will do everything it can to assist the Coroner in any ongoing Coronial process."
It was previously reported that Nikki's family thought she had been discharged from the hospital too soon. Her friends and family raised money via a GoFundMe page to pay for Nikki to receive private specialist treatment and she was due to enter a private facility in Devon the week after her discharge from the hospital.
Nikki - who became a household name in 2006 thanks to the reality show - had been open about her battle with the eating disorder over the years and had recently relapsed. Her mum Sue told The Morning in March that the Covid-19 lockdown affected her daughter's mental health.
"With Covid, it sounds crazy but stuff like gyms closing impacted her," she said. "In order for her to eat she needs to know she can exercise, so when they closed it was quite a worry, the isolation as well."
