Health authorities in the United Kingdom have warned the public against cheap Brazilian butt lift (BBL) from overseas clinics.

The invasive cosmetic procedure is being offered abroad for under £3,000, inclusive of hotel accommodation and flight fare, to entice customers. In contrast, local BBL costs 70 percent higher in the United Kingdom, according to the National Health Service (NHS).

However, a spate of deaths and medical complications arising from botched BBL surgeries, with the NHS frequently having to treat patients when they return home, prompted the warning posted on the NHS website on 21 December.

In the post, NHS National Medical Director Professor Sir Stephen Powis also said BBL surgery has the highest death rate of all cosmetic procedures as the fat injected into the buttocks can lead to a pulmonary embolism, which is a blockage in a blood vessel in the lungs that can be fatal.

“While many people’s social media feeds will be full of enticing looking offers in the run up to Christmas, the reality is these bargain basement cosmetic procedures are potentially deadly,” he warned.

Meanwhile, a literal case of butt lifting has been remedied using 3-D printing technology.

Mystic Aquarium senior veterinarian Dr. Molly Martony revealed that the company Adia measured and scanned Charlotte for the design of a customized prosthetic harness to remedy a “bubble butt syndrome” (BBS).

Charlotte, a green sea turtle at the Connecticut aquarium, is suffering from BBS years after it was hit by a boat that damaged her shell and spinal cord.

The BBS caused the male green sea turtle to be buoyant and vertical in the water because air in its gastro-intestinal tract lifts its butt up. The position can damage its organs, Claire Bolster, Charlotte’s handler, said, according to ABC News.

With the prosthetic harness fitted on Charlotte’s shell, weights can be placed to pull his butt down and let him swim at level and more smoothly.
