October 21, 2026 | Body Contouring, Patient Safety, Plastic Surgery Consultation
“What BMI do I need?” It is the first question in half my body consults, usually asked before hello. The number in my practice is under 35, ideally under 30. Here is why, and here is when I bend it.
What Actually Goes Up Above 35
“The plastic surgery literature has shown that complications go up the higher the BMI. The most likely complications in higher BMIs are seromas, infection, blood clots, and longer surgical times.”
“BMI above 35 is regarded as class II obesity, and at this point we see risks significantly increase.”
The published numbers, for the record. A review of 127,961 aesthetic surgery patients in the CosmetAssure database (Gupta and colleagues, Aesthetic Surgery Journal, 2016) found major complication rates of 1.6 percent at normal weight, 2.3 percent overweight, 3.1 percent at BMI 30 to 39.9 and 4.2 percent at BMI 40 and above, with the highest rates in abdominoplasty and lower body lift. In abdominoplasty specifically, Brito and colleagues (Aesthetic Plastic Surgery, 2020) reported a 74.1 percent overall complication rate in obese patients against 32.5 percent for the whole series, driven mostly by seroma. Ghnnam and colleagues (World Journal of Plastic Surgery, 2016) found the same pattern above BMI 30: longer operations, longer stays, more drainage, more wound problems.
Those are their data, not mine. My own answer to a patient in 2018:
“It is true that your BMI should be ideally under 30 for plastic surgery. In my practice, I recommend for the BMI to be under 35, as I have not seen increased complications for most procedures. You should understand that your results may not be comparable to somebody with the BMI under 30. You should still see an improvement, and this often motivates you towards a healthier and more active lifestyle.”
Why the Result Has a Ceiling Too
“It is also important to note that at higher BMI, certain results are not possible, and many times it can limit your final results. For example, in higher BMIs, the abdominal plication cannot be performed as tight, because with higher BMI there is more visceral fat, and when we tighten the abdominal muscles, the visceral fat presses up against the diaphragm and the lungs. Therefore, if we plicate too tight in the presence of visceral fat, it can compromise breathing after surgery.”
That is the tummy tuck ceiling. Not skill. Physics and breathing.
“Also, the five liter limit on liposuction for safety applies to all BMIs, so in higher BMIs that five liter reduction is proportionally much less than in a normal weight patient.”
Five liters off a large frame is a smaller change than five liters off a small one. More on the cap in liposuction. And to a patient worried about a flat result:
“It is clear from your picture that you have a significant amount of upper abdominal distention which is usually caused by the visible fat pushing outward on the abdominal wall. While a tummy tuck will help tighten the abdominal muscles and considerably improve your abdominal contour, you may not obtain a completely flat abdomen.”
| BMI | What I tell the patient |
|---|---|
| Under 30 | Ideal. Full menu, best results. |
| 30 to 34.9 | I operate. Results may not match the under-30 patient. Diabetes is fine if well controlled. |
| 35 and above | Class II obesity. Risks rise. Case by case, usually weight loss first, sometimes staging or a panniculectomy. |
The Patient Who Has Plateaued
“These decisions occur on a case-by-case basis, and there are exceptions. During consultation, if the patient mostly has external subcutaneous fat and excess skin, then these areas can be targeted. The exception is when most of the fat is visceral and lives inside the abdominal cavity. This fat cannot be targeted with plastic surgery and increases risks.”
“I am always an advocate for patients to continue their weight loss journey to get to a healthier weight and BMI to decrease complications. But the fact of the matter is that some patients have just plateaued and are no longer able to lose more weight. They continue to diet and exercise and use GLP-1s, or they may have already had a bariatric procedure. But the fact that they are not moving the scale is frustrating and sometimes causes psychological distress, resulting in bounce backs and weight gain, almost a vicious cycle of a yo-yo effect.”
“At this point, if the patient agrees that the benefits will outweigh the risks, and it gets them motivated to a healthier weight and lifestyle, I agree to proceed.”
How I plan around the GLP-1 patient is in my GLP-1 surgery planning post, and the timing after the weight comes off is in body contouring after weight loss.
Staging, the Six Hour Rule, and the Panniculectomy
“At high BMIs, we also consider staging. The ideal is to keep a surgery under six hours, and at higher BMIs each procedure can take longer than usual. Many times we will opt to perform liposuction first and the excisional surgeries later. Sometimes we elect to remove the tissues, like in a panniculectomy, to improve quality of life, hygiene, and mobility, without emphasizing the cosmetic result.”
Six hours is my practice standard, not a law. The panniculectomy conversation gets its own post tomorrow.
Diabetes, and the Other Number
“Diabetes is not a contraindication as long as it is well-controlled.”
And BMI is not the only number I look at. Visceral fat is the one that limits the plication, and I told Woman’s World this summer how responsive it is: “Visceral fat is very responsive. It’s usually the first fat to arrive when your habits slip and the first fat to leave when your habits improve.” Protein before and after surgery helps too; that post is here.
