Plastic surgeries, butt lifts, and many more such things done to your body are no longer new, but what many do not know are the risks it usually involves, and often a pungent smell that it leaves. Among the many such surgeries are BBL and the BBL Smell. What Is BBL?BBL is the Brazilian Butt Lift surgery. This is a cosmetic process to enhance the size and shape of one's buttocks through a transfer of fat. The process is also known as buttock augmentation with fat grafting.As per the National Health Service, UK, BBL could be a dangerous surgery, and the main concern remains the injected fat, which could cause a blockage in a blood vessel in the lungs and could be in fact fatal. It also includes risks of a serious skin infection and lumpy scars.Also Read: Study Suggests Six Personality Traits That Make Us 'Cool' – Is It Genetic Or Acquired? However, there is another effect that people may not talk about, it is the BBL Smell.Does BBL Really Smell?Dr Frita McRae Fisher, MD, a triple board-certified medical doctor with certifications in nephrology, hypertension, and diabetes is also an influencer on social media channels. In one of her YouTube videos, Dr Frita explains if BBL smells or not, why does it smell and how old is too old for BBL. She explains that BBL can smell if you develop fat necrosis. What Causes BBL Smell?This is when the fat tissue that is injected into the buttocks dies. Dr Frita explains that when you get a BBL done, the fat tissue is injected in the buttocks below the skin and above the muscle. However, she explains, "sometimes some of these fat cells die and when they do, they can release cellular debris and toxins, which can produce a foul odor." A Chicago-based Impressions Face and Body, Dr Eric Anderson told the Daily Mail, "The BBL smell is real."Not only does the death of the cell cause this smell, but it could also be because the patients are sweating or siting for long periods. Other factors could be unhygienic habits, which can cause BBL smell.Also Read: First UK Adult To Receive Treatment For Type 1 Diabetes Drug Undergoing TrialsWhy Do Fat Cells Die after BBL Surgery?Dr Anderson explains that if a patient is "overfilled" with fat during the process, the tissue could die in the buttocks. “When there is more fat in an area than the blood supply allows, the fat will die through a smelly process called fat necrosis, which can lead to infections that need antibiotics, hospitalizations, and even sepsis,” he explained. What Are The Other Reasons For A Smelly BBL?Dr Frita also seconds with Dr Anderson's opinion that there are a variety of causes that can lead to a smelly BBL.She goes on to explain the number 2 reason for the same. "If you develop a bacterial infection, your BBL can smell. The BBL surgery takes place right near the area where you make your bowel movements, and so it is very possible for fecal mater to come in contact with the surgical wounds. If this happens, you can develop a bacterial infection, which can produce a foul odor."Other factors include the surgeon not using proper sterile tools and techniques to perform the surgery, and having poor personal hygiene practices.Dr Frita explains that right after the BBL surgery, "your buttock region would be larger than before." This is what causes more sweat in between and underneath the buttocks, this is what requires an extra care and hygiene. However, she clarifies that most BBL do not smell, if it does, it is best to get it checked by your doctor. She suggests that one must also see a doctor if their BBL is leaking, causing chronic pain or have a high fever after the surgery.
