Why Do You Need to Gain Weight in Order to Undergo Plastic Surgery?

undergo plastic surgery gain weight


There are some plastic surgery interventions that require patients to gain weight before going under the knife. This is particularly true when fat transfer is involved. Fat transfer surgeries require patients to have excess fat in their body that can be used as donor fat to enhance specific areas of the body.

During the consultation for procedures that require fat transfer, the plastic surgeon will not only examine your body areas that need aesthetic improvements but also check whether you have enough excess fat in your body that can help meet the donor fat requirements. If you lack excess fat, you may be told to gain weight and then consider the surgery.

Reasons you need to gain weight to undergo plastic surgery

Plastic surgery procedures that require fat donation require the patient to have excess fat in his or her body. The excess fat is used as donor fat. The common areas the plastic surgeon will look for excess fat include the abdomen, sides, flanks, upper back, and thighs. If the plastic surgeon thinks there is no fat in these areas or your body doesn’t have sufficient excess fat to transfer to the body areas that require contouring, you would be advised to gain weight and then undergo surgery or look for other options.

The primary factor that necessitates the need for weight gain before plastic surgery is the need for fat transfer. The common fat transfer procedures are the fat transfer to the butt (Brazilian butt lift) and fat transfer to augment the breasts. There are many patients who consider these procedures; however, they lack the excess fat in their body to achieve the desired aesthetic results. The reason why most women prefer fat transfer to the butt and breasts is that it delivers natural results and the procedure is relatively safer. It does not involve the use of foreign objects such as implants.

Some patients who consider fat transfer procedures often presume they lack the fat required to achieve the outcomes of the procedure. Instead of doing self-examination, patients are encouraged to meet with board-certified plastic surgeons and have their bodies examined. Even though the volume of excess fat available in your body is the primary factor in determining your candidacy for the surgery, there are other factors that need to be taken into account as well.

If you are looking to achieve a mild projection in your butt, it can be achieved with even the minor amount of excess fat available in multiple areas of your body. However, if you aim to add more projection to your backside and lack enough excess fat in your body, you will be told to gain a few pounds.

However, if you already have enough excess fat in your body, gaining weight before the surgery has the tendency to make the results worse because it will change your figure. Weight gain will lead to the deposition and expansion of fat not only under your skin but also around your organs and between your abdomen. The fat inside the abdomen and around the organs cannot be removed via liposuction. This means unnecessary or excessive weight gain before plastic surgery can have negative impacts on your aesthetic appearance.

Typically, you would require an average amount of 1 liter of fat to achieve noticeable results from the Brazilian butt lift. However, the plastic surgeon will remove two liters of fat from your body areas because almost half of the removed fat comprises fluids, blood, impurities, dead fat cells, and damaged fat cells. These will be removed from the collected fat during the purification process.

It is important for patients to be very cautious when gaining weight before plastic surgery. You should gain weight before the intervention only if your surgeon says so. Also, make sure to gain the amount of weight recommended by your surgeon. Do not exceed that limit. The surgeon will determine the weight gain you need by knowing your aesthetic goals, examining your fat donor sites, evaluating the aesthetic flaws, and tension and elasticity of the skin. In case you have very tight skin, there is a risk more fat injection would trigger re-absorption of the fat by your body.

The fat transfer procedure

Butt augmentation and breast augmentation are the two trendy plastic surgery procedures that may require the use of your own body fat. While the surgeries can be performed by using implants, most patients opt for the fat transfer procedure because it is safer and the results are natural. Both procedures require different amounts of excess fat or donor fat. The buttocks require more fat during augmentation than the breasts.

If you are considering buttock augmentation, you will be required to have more excess fat in your body. On the other hand, patients considering breast augmentation via fat transfer will not be required to have a large volume of excess fat in their bodies.

Both procedures are performed under IV sedation or general anesthesia. The plastic surgeon will the use liposuction to remove the excess fat from your body areas like the abdomen, sides, flanks, etc. Liposuction involves the use of a hollow tube called a cannula that is inserted into the fat donor site through a tiny incision. The cannula is given a back and forth motion to dislodge the fat cells from the surrounding tissue. The fat is then removed with the help of a suction pump that is connected to the liposuction cannula. The incision is then sutured and closed, and the same process is repeated on the other fat donor sites until enough fat is collected to deliver you the desired outcomes.

In the next step, the plastic surgeon will process the fat and remove the impurities, dead fat cells, blood, and damaged cells. The surgeon will do this by spinning the fat in a centrifuge at a high speed.

In the last step, the plastic surgeon will transfer the pure and alive fat cells to your butt or breasts. The fat transfer or fat grafting is done extremely carefully with a special needle and without placing incisions in the target areas.

The fat grafting process is extremely meticulous because it will ultimately shape your butt or breasts. The plastic surgeon’s credentials, experience, skills, sense of aesthetics, and artistry are crucial to the achievement of the desired results. Once the fat is transferred to the butt or breasts, your body will take some days or even weeks to vascularize them. The desired outcomes will not be achieved until the fat grafts have been vascularized.

The results achieved via fat transfer will last a lifetime only if you maintain a stable weight. Whether you have undergone butt augmentation or breast augmentation, the fat transferred to the target areas will behave the same way as the fat in other parts of your body. This means weight loss will affect these areas in the same way as other areas of the body. Considerable weight loss will shrink the body area that has received the fat transfer. Be sure to maintain a stable weight if you want to keep the aesthetic improvements on a sustainable basis.

Can someone else’s fat be used as donor fat?

There are many patients who lack the excess fat to undergo the fat transfer procedure and are not ready to gain weight. They often ask whether it is possible to use someone else’s fat during the surgery. This is not possible at all because fat donation is just like a tissue transplant. Tissue transplanting has sophisticated rules, requirements, pre-requisites, and techniques. Moreover, it is extremely risky because your body may react adversely or reject the donor fat.

From a medical point of view, if you get the fat donation from someone who is not your identical twin, then chances are your body will reject the fat. It is for this reason that in case of tissue transplantation, patients are required to take immune-suppressants for a lifetime. The use of immune-suppressants is extremely dangerous.

Options for Financing Your Plastic Surgery Intervention


There are many patients who will be required to gain weight before the plastic surgery procedure. Whether you need to gain weight depends on the type of surgery and the volume of excess fat required for delivering you the desired outcomes. Patients who are undergoing butt augmentation and breast augmentation via fat transfer need to have enough excess fat in their body areas that can be used as donor fat. If you lack the required volume of fat, you must gain weight before the surgery.
