The glamour model underwent the cosmetic procedure in preparation for her wedding to fiancée Jamie O'Hara, but was left in agony after her right breast swelled to "literally the size of [her] head" and ruptured.
Blood clots were discovered during an operation to have her implants removed, resulting in Lloyd being hospitalised for five days.
"I lost over a litre of blood. Afterwards I needed an emergency blood transfusion because I had half the haemoglobin level of a normal person," she told Reveal.
"Thank God they found it, though - if they hadn't, I might not be here today."
However, Lloyd was rushed back to hospital again when her right breast continued to grow "back to massive size" within two days.
"I looked like I had giant implants," she said. "I felt as though my breast exploded and this time it happened a lot faster than before.
"My left breast went down to literally nothing. It was just an empty sack while the right one was huge."
Doctors were baffled when they took "a litre of milk" from Lloyd's breast, as the 28-year-old hadn't fed infant son Harry for six months.
Despite the ordeal, Lloyd insisted that her wedding to O'Hara in May "is happening - with or without boobs".
