Heidi was just 23 when she underwent a mini brow lift; botox; a nose job; fat injections in her cheeks; nasolabial folds and lips; a chin reduction; neck liposuction; had her ears pinned back; a breast augmentation revision; liposuction on her waist, hips and inner and outer thighs; and a buttock augmentation.
Now the former star of The Hills regrets the changes she has made to her body, saying she was insecure at the time.
'I definitely regret the surgeries that I have had over the years, I think I was so young and in such an unstable situation in my life with so much going on and so much pressure,' she said.
'It is really hard to be a woman in this day and age with all the media and internet and comments, there is so much more negativity coming at people, it is a lot easier to be insecure and let that get to me.
'I definitely regret the surgeries that I have had over the years'
'I let myself be a victim of that and I listened to what other people said and let myself become really insecure and I had a doctor that made it sound really easy and a quick fix and it ended up being a hard road and I inflicted a lot of pain, mentally and physically, on myself.
'Over the past few years my implants have handicapped me'
She added: 'If I had to go back and do it again I definitely wouldn't and I would not recommend that.'
The reality TV star recently underwent an operation to reduce her F-cup breasts to a size C after claiming her huge implants had ‘handicapped’ her.
'Over the past few years my implants have handicapped me, I have not been able to do a lot of things,' she said.
'Over the past nine months I have not been able to do laundry, or look after my dogs or clean my house and I have had to stop working out because my injuries are so severe I cannot even do simple things like rowing or running.
'I have been limited in my everyday life and the last few months especially have been so uncomfortable and in pain that it has really been taking a toll on my life and my mood.'
She is now warning others to avoid going under the knife.
She says: 'My experience should tell other young women that beauty and confidence comes from within, it does not matter what you do on the outside if you are not happy and do not feel beautiful and secure and confident on the inside then no amount of surgery will change that or make you happier.
