Reality star Charlie King says having body dysmorphia has taken him "to the depths of despair".
The 36-year-old, who appeared on The Only Way is Essex, says he struggled with his body image before going on TV.
He appeared before the Health and Social Care Committee on Tuesday as part of its inquiry into the impact of body image on mental and physical health.
Charlie spoke about how his mental health condition has affected his life.
He has been diagnosed with body dysmorphic disorder (BDD), which is a mental health condition where a person spends a lot of time worrying about flaws in their appearance which might be unnoticeable to others.
"During lockdown I became obsessed with my nose," he told MPs on the committee.
"I saw a plastic surgeon who agreed 'we could fix that' and he gave me validation."
He says there was no assessment by the surgeon on his mental health, or a need for him to disclose that he suffered from BDD.
He told the committee that he believed surgeons should check with potential patients to see what their mental state is when they pursue cosmetic procedures.
Plastic surgeon Nigel Mercer is a former president of the British Association of Plastic Reconstructive and Aesthetic Surgeons, and says that all surgeons who are part of his organisation and of the British Association of Aesthetic Plastic Surgeons, are expected to have an advanced understanding of how to identify psychological factors in patient consultations.
Many within the organisation have taken an advanced cosmetic surgery course which covers mental health, and he says the majority of surgeons offer counselling to patients, but take-up is low.
Charlie said when the nose job went wrong, he "went to the depths of despair".
"I had to go and live with my mum because I couldn't earn money and I was depressed. There were no resources [from the plastic surgeon to help] and that year was so challenging."
His testimony comes as 80% of people said their body image had a negative impact on their mental health, in a survey conducted by the Health and Social Care Committee.
More than 1,500 people took part in the survey, which also asked about the accessibility of NHS mental health services, and whether the government was taking the effects of negative body image seriously.
'I felt so embarrassed'
Charlie says he wants more awareness around BDD so that people can get the right help.
"I felt so embarrassed as a man, It feels vacuous but people [with BDD] need to know that what they feel is valid and that it's treatable," he says.
"We need to give people access to what they need, instead of them thinking they need to change themselves.
He says his anxiety and depressed stemmed from body dysmorphia and "if I'd have understood that more I might not have been in this position."
