Bottoms up: Why butt lifts are big business in parts of Africa

(CNN)While some women are doing everything they can to get rid of extra weight, a larger behind is so desirable in some countries that it's fueling a whole industry of creams, surgery and padding.

2015 was called "the year of the rear" by the American Society of Plastic Surgeons.
"In some social circles it's like, 'You haven't had your butt done? What's wrong with you?'", explained Dr. Stanley Okoro, a plastic surgeon who works in Atlanta, Georgia, and Lagos, Nigeria.
When he's in Nigeria every two months, Okoro said he's able to do four to six butt lifts in a week. Each one usually takes six to eight hours, and Okoro is often booked up until late. "Sometimes I'm in surgery until 1am. It's exhausting," he said.

    Why the rear has grown

    Dr. Okoro says the biggest contributor to the rise in buttock surgery is without a doubt social media.
    "It is a combination of increased popularity of Kim Kardashian, known for her ample backside, as well as increased popularity of social media," said Dr. Matthew Schulman, a plastic surgeon in New York City.

    "The pressure to look good is what's driving people," said Okoro. He said in Nigeria, the massive film industry, commonly referred to as Nollywood, has driven the demand for the perfect butt.
    A growing middle class has significantly contributed to the growth of cosmetic plastic surgery -- once a forbidden industry -- in Nigeria and Ghana, added Okoro.
    The availability of smartphones in Africa and access to social media has also fuelled the rise in cosmetic surgery, Okoro said.
    Over the past three to five years increased economic power and awareness of cosmetic surgery has fueled the popularity of such procedures, said Dr. Ojochide Ebune, a Nigerian surgeon and assistant secretary general of Nigerian Association of Plastic, Reconstructive and Aesthetic Surgeons.
