Heidi Montag claims her breast implants "handicapped" her.
The former reality TV star had her boobs reduced from an F cup to a C cup four weeks ago, after her larger implants caused her severe back and neck pain, numbness in her arms and prevented her from doing everyday tasks.
She is quoted by the MailOnline as saying: "Over the past few years my implants have handicapped me, I have not been able to do a lot of things.
"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."
Heidi underwent 10 surgical procedures in a single day in 2010, when she was just 23 - including breast implants and a nose job - but now says she wishes she had never gone under the knife.
She said: "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.
"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.
"If I had to go back and do it again I definitely wouldn't and I would not recommend that.
"Once you get surgery you can never be the same size you were, you can never really take it back so it is something you need to think about seriously.
"I wish that before I got my implants I had goner to a spine specialist and seen other doctors and consulted with them and got opinions of what size breasts I should have had and what my body could support."
Now happier with her body, Heidi is currently holidaying with her husband Spencer Pratt in Cabo San Lucas, Mexico, to mark five years of their marriage.
