Top Surgery For Plus-Size Patients: BMI Over 30

BMI Limitations: Is it Safe for Plus-Sized Patients to Undergo Top Surgery?

As opposed to other types of gender-affirming surgery and plastic surgery, top surgery patients with higher BMIs are not at a greater risk of serious complications than their counterparts with lower BMI. Many providers impose BMI cutoffs for top surgery––like a maximum BMI of 30 or 32––that are based on industry standards of cosmetic plastic surgery. However, gender-affirming chest reconstruction and breast reduction surgeries are not cosmetic, but oftentimes medically necessary procedures. In other words, top surgery is safe for plus-sized patients and necessary to treat gender dysphoria in some transgender men and non-binary individuals.

Weight Stigma and Fatphobia

Disappointingly, the stigma against people with higher BMIs, sometimes called fatphobia, is pervasive amongst many medical providers. Peer-reviewed research has shown that plus-sized patients frequently experience discrimination and disparaging attitudes on behalf of their healthcare providers. For example, conversations may be centered around labels of patient “non-compliance” or “laziness” if weight-based goals are not met. Several patients with obesity often experience providers blaming their health concerns on their weight, being dismissive instead of meaningfully looking for other causes.

When it comes to gender-affirming top surgery, plus-sized patients are often denied care by arbitrary BMI cutoffs. Alternatively, our approach at the GCC is to work with a patients’ unique medical history and need to reduce the risks of surgery. After all, having a BMI in the obese range does not necessarily mean a patient will have certain medical conditions that bring a higher risk of surgery.

BMI and Surgical Eligibility at the GCC

At the Gender Confirmation Center (GCC), no one is ruled-out of surgery because of a single numeric factor like BMI. Instead, our surgeons take a holistic approach to work with patients on a case-by-case basis to determine what considerations or accommodations we will need to ensure someone’s safety through surgery. BMI is still a considered factor in the eligibility requirements of the different hospitals and surgery centers.

You can request a free consultation with any of our GCC board-certified providers to make a surgical plan that fits your unique goals and needs. All of our providers are size-friendly; they have extensive experience working with patients with a wide-range of BMIs.

Below, Dr. Jacobs (he/him) talks about how our practice plans around the risks associated with undergoing surgery with a BMI over 30 without denying our patients access to gender-affirming care:

Top Surgery Techniques and Options for Plus-Sized Patients

Common Incision Types

Most patients with a BMI over 30 that come into the GCC for care have a D cup-size or greater. Patients often choose between a double incision, an inverted T or a buttonhole technique due to the amount of tissue they would like to have removed. Each of these procedures leave visible scars on the chest, whose texture and discoloration can be managed with proper scar care.

Patients can choose to have their nipple-areolar complex preserved, have their nipples grafted, or have their nipple-areolar complex removed entirely. You can book a free consultation with any of our surgeons to discuss which of these options would be best for you.

Maintaining Heightening Nipple Sensitivity

Maintaining heightened sensitivity in the nipples is a priority for their top surgery. Patients can choose between the following types of techniques:

• Pedicle preservation: The inverted T and buttonhole incisions keep the nipples attached to their original blood and nerve supply. This is accomplished by preserving the pedicle: a mound of tissue behind the nipple. This means that this technique is not ideal for patients who want a completely flat result, as some tissue is left behind.
• Nerve reconstruction: Sometimes called neurotization, this technique involves dissecting the nerve attached to the nipple, to preserve it and connect it to the nipple graft. That said, this technique may not be ideal for patients with a BMI over 30. This group of patients often have poorer nipple sensation before surgery. Poor sensation was also observed in patients with greater amounts of breast tissue removed (800g or more).

Safety & Health Concerns for Plus-Sized Patients Undergoing Surgery

While there are some concerns associated directly with a patient’s weight, in most cases, your candidacy and risk level for surgery is determined by the underlying medical conditions you have. For example, if you have a diabetes diagnosis, your surgeon will need to know from one of your healthcare providers how your blood sugars have been managed before you undergo surgery. This is to decrease possible complications like delayed wound healing or infection.

That said, patients whose BMI is in the obesity range often are at higher risks of respiratory and cardiovascular problems under anesthesia. These concerns can generally be managed by your anesthesiologist and surgeon. For this reason, patients with a BMI >60 may not receive approval to proceed with surgery based on safety concerns and functional limitations that may make it difficult to provide adequate air to the lungs during surgery.

Choosing a Surgeon: Experience with Plus Size Bodies Matters

Given the health and healing concerns that could potentially arise with patients with higher BMIs, we recommend that patients seek out surgeons with an extensive portfolio of working with this population.

Surgeons that are experienced working with larger bodies are often better able to deliver a patients’ aesthetic goals. For example, when large amounts of tissue are taken out, a patient is at risk of having dog ears after surgery. You can speak with one of our surgeons in a free consultation about incision options that can reduce the risk of dog ears.

GCC patients with higher BMIs often report having very positive experiences. For example, one of our top surgery patients shares:

“Well, it’s been over a month….and just a few says ago I FINALLY got progress on my surgery! I went to the Gender Confirmation Center of San Francisco……and man I bawled my eyes out when I finally met a surgeon who wasn’t immediately disgusted by my size. He gave it to me straight….yeah it would be a bit more complicated, due to my BMI, but he reassured me that we would figure something out. “
