Fat Freezing Vs Gastric Bypass Surgery

  • Fat freezing is a fast and non-invasive procedure that permanently removes stubborn subcutaneous fat.

  • Gastric bypass is an extensive surgical procedure, designed for large amounts of weight loss. It reduces the size of the stomach thereby reducing food consumption.

  • Fat freezing provides fat loss in targeted subcutaneous fat areas.

  • Gastric bypass can help with illnesses related to obesity such as sleep apnea, arthritis, high blood pressure, and even metabolic disorders like high cholesterol and diabetes.

  • Fat freezing is a walk-in walk-out procedure. It is cheaper than any surgery and has less serious risks and side effects.

Key Takeaways

INTRODUCTION

In this clinic, we often see clients who have been considering all types of fat-reduction technologies, one of which is gastric bypass. 

There are many invasive and non-invasive fat reduction treatments available in this day and age. Two popular options are fat-freezing and gastric bypass surgery. Fat freezing is a non-invasive procedure that uses controlled cooling to target and permanently eliminate stubborn fat cells, while gastric bypass is a surgical procedure that alters the digestive system to achieve significant, long-term weight loss. Each treatment has its own indications, benefits, risks, and considerations, making it important to understand the differences when making an informed decision.

Whether you're a busy parent, a bride or groom-to-be, or a young professional looking to improve your physique, understanding these procedures can help you choose the right path for your needs and lifestyle.

Understanding Gastric Bypass

  • Gastric bypass surgery, also known as Roux-en-Y gastric bypass, is an invasive surgical procedure that is used to treat obesity. It is one of the most effective type of bariatric surgery, which is a surgery that aims to help people lose excess weight

    eg. sleeve gastrectomy or gastric banding.

    Gastric bypass surgery is recommended for people who are morbidly obese (BMI = 35–50) or super-obese (BMI > 60), and those with obesity-related health problems such as diabetes, sleep apnea, high blood pressure, and acid reflux. 

    The procedure requires conducting a cut through the skin and underlying tissue of the abdomen to allow access to organs for surgery. It involves two steps:

    • The first is creating a small stomach pouch that will limit the amount of food that can be eaten at once, making you feel full sooner.

    • The second is changing the path of the food through the digestive system which will reduce the amount of calories and nutrients absorbed. 

    Doctors make a small pouch at the top of the stomach, around 20–30 milliliters in size to hold food. This pouch is then connected directly to a section of the small intestine called the "alimentary limb," allowing food to bypass most of the stomach and a short portion of the small intestine. As a result, digestion happens more quickly, and food doesn’t mix with digestive juices until later in the process, reducing calorie absorption. Advances in laparoscopic techniques have made this procedure safer and less invasive, but it requires specialized training and expertise to perform successfully.

  • The process of preventing food from being fully absorbed is known as malabsorption. Gastric bypass surgery is particularly effective at reducing fat absorption (and to a lesser extent, protein absorption) because the smaller stomach size and shorter digestion time limit food’s exposure to digestive enzymes. Additionally, the reduced contact with bile—essential for breaking down fats—further inhibits fat absorption. While carbohydrates can still be absorbed, their intake is also reduced, contributing to weight loss. However, carbohydrate absorption can sometimes lead to weight regain, making it a key factor in consideration of the long-term success of the procedure. Another effect of gastric bypass is a decrease in ghrelin production, the hormone responsible for stimulating hunger, as the surgery removes a portion of the stomach lining where the cells that procude ghrelin reside. Together, these mechanisms contribute to significant weight loss after the procedure.

Understanding Fat Freezing (Cryolipolysis)

  • Fat freezing/ cryolipolysis, also called CoolSculpting or cryolipolysis, is a non-invasive procedure that targets and eliminates stubborn fat by using cold temperatures. During the treatment, a special cup-like device is used to gently pull the skin and fat into the cup and apply cold temperature, freezing the fat cells without harming the surrounding skin or tissue. These frozen fat cells eventually die off and are naturally processed and eliminated by the body's immune system.

    The procedure is performed without the need for general or local anesthesia. Once the fat cells are destroyed during the treatment, they are permanently eliminated from the body.

    During the procedure, clients may initially feel a sensation of tugging or pulling as the tissue is drawn into the vacuum applicator. A slight stinging may also occur as the area becomes numb. After the procedure, it is common to experience temporary numbness and tingling due to the cold exposure, but these sensations typically resolve within a few days.

  • Fat freezing has been studied extensively in both animal and human models. The results have been excellent with visible and fast results. The effects can be visible in as little as 2-4 weeks after treatment with final results showing up to a 25% reduction in fat. This efficacy is seen with only 1-2 sessions, proving its superiority. Fat reduction is permanent during freezing because the cells are removed from the area, leading to a long-lasting solution to stubborn fat pockets and bulges. Patients are highly satisfied even after just one session of this therapy because of this effect.

    A study by Krueger et al. (2014) quotes two additional studies and states, “The clinical efficacy and safety of cryolipolysis has been studied in both human and animal models. In two separate studies, animal models demonstrated a reduction of up to 1 cm or 40% of the total fat layer thickness after a single exposure without harming the overlying skin.” (Manstein et al., 2008 & Zelickson et al., 2009)

    An additional reference included in this study - refers to the article by Coleman SR et al,   titled “Clinical efficacy of noninvasive cryolipolysis and its effects on peripheral nerves”  States that “in a study published in 2009 involving ten subjects reported a 20.4% and 25.5% reduction in the fat layer 2 months and 6 months after treatment, respectively

  • Pros:

    • Results in permanent fat loss with as little as 1 session

    • Doesn't require general or local anesthetic

    • Most clients see a visible reduction within 2-3 weeks

    • Effective results at 12 weeks due to the removal of fat cells via the lymphatic system

    • Fewer treatments are required to reach the desired result when compared with other non-invasive treatments (Including Radio Frequency or Fat Cavitation ) See more Fat Loss Treatments comparison here.

    • Targeted fat loss

    • No dietary changes required

    • Little to no downtime

    Cons:

    • The feeling of pulling during the procedure

    • Mild stinging sensation as the skin becomes numb that may last a few days after treatment

    • Repeated sessions may be needed depending on the thickness of the fat layer

    • Targets only subcutaneous fat

Fat freezing (or cryolipolysis) is clinically proven to deliver permanent subcutaneous fat loss. Initial results usually become noticeable within 2-4 weeks, with final results typically visible around 12 weeks. Clinical studies have shown an average fat cell reduction of 26%. However, with advancements in treatment technology, this has increased to 30-40% reduction per treatment. Since fat cells are permanently removed, the results are permanent. Patient satisfaction rates are high, with studies showing up to 73% of patients are content , making fat freezing a more effective and practical solution for fat loss.

Fat Freezing vs Gastric Bypass

  • Fat Freezing: The cost of fat freezing varies depending on the size of the treatment area and the number of sessions needed. Prices start at $499 and can be reduced to as little as $249 if purchased as part of a package. 

    Since fat freezing is considered a cosmetic procedure, it is generally not covered by insurance. 

    Gastric Bypass: The cost of gastric bypass surgery can vary significantly depending on the location, the surgeon's experience, and the healthcare facility. It ranges between $15,000 - $35,000 in Australia.

    Insurance coverage for the procedure often depends on the patient's individual policy and whether they meet specific criteria for weight-loss surgery like their BMI and obesity-related health conditions like diabetes or high blood pressure. Patients typically require weeks to months off work to heal, increasing the overall cost (lost wages and use of holiday leave) especially if their job involves physical labor. Patients are advised to plan accordingly for this potential financial impact.

  • Fat freezing is often referred to as a "Lunchtime treatment" due to its non-invasive nature and quick recovery time. After the procedure, clients can immediately return to their usual activities with no downtime required. This makes it a convenient option for those looking to target stubborn fat without interrupting their daily routine.

    Gastric bypass surgery has a longer recovery period of 4-6 weeks, with careful monitoring after surgery needing a hospital stay of 2 to 3 days. After leaving the hospital, patients must follow a gradual return to normal activities, avoiding strenuous exercise or heavy lifting for about 4 to 6 weeks for proper healing. Diet restrictions and adjustments, such as smaller meals and avoiding certain foods, also play a role in the recovery process. Full recovery can take several months as the body adjusts to the changes in the digestive system.

    And Gastric bypass diet: What to eat after the surgery here.

  • Fat freezing is a proven method for permanent fat reduction with just one session. occasion some clients see results beginning to appear at 5-7 days.  Although clinical trials and consideration of anatomy and physiology indicate that final full outcomes and results are visible at around 12 weeks.

    Clinical studies show that fat reduction can reach up to 30-40% in the targeted area, as the fat cells are permanently eliminated by the body. It can be effectively used on areas such as the chin, abdomen, thighs, flanks (love handles), back, arms, knees, and even the underarms. The patient satisfaction rate with CoolSculpting, a trade name for a particular fat-freezing machine,  is as high as 73%, making it one of the most effective non-invasive fat-reduction treatments on the market. This technology is very effective in reducing fat layers and ensuring long-lasting results in targeted areas.

    Gastric bypass results in rapid weight loss over the first 2 years with a final weight reduction of 68 - 83% at 2 years. This is the equivalent of a 20-point decrease in body mass index (BMI). Then, weight starts to plateau in the third year and increases after that, especially if it is not supported by diet and exercise. The success rate can be as high as 90% in patients with morbid obesity (BMI = 35–50), but it can drop to 60% for super- obese patients. A study found the risk of surgical failure was also high in the super-obese group. The majority of patients (74% at 10 years) were able to lose weight and maintain it as long as they incorporated healthy dietary changes and exercise. The effects on diabetes and high blood pressure were also very good, with 51% of patients having remission at 12 years after surgery. The reduction in abdominal pressure and maintaining the lost weight can improve many co-morbidities like gastroesophageal reflux and sleep apnea,  as well as arthritis of weight-bearing joints and asthma.

  • Fat Freezing (coolsculpting): While the method is generally considered safe, there are some minor side effects to consider. During the procedure, patients may experience a pulling or tugging sensation as the fat is drawn into the applicator. Additionally, a mild stinging or numbness may occur because of the cold temperature that is applied on the skin which can persist for a few days after the treatment. Some individuals may require multiple sessions to achieve their desired results if the fat layer is thicker. It’s also important to note that fat freezing only targets subcutaneous fat, meaning it does not affect deeper fat layers or visceral fat, which may require different treatment approaches for optimal results.

    Gastric Bypass: Although there are many benefits to having a gastric bypass surgery, there is a 0.5- 1% chance of morbidity and mortality. Studies have shown that there is a higher risk of death, disease, or complication in patients aged above 55, weight above 160 kg, truncal obesity, and male gender. In addition to complications due to anesthesia administration, the most common complications of gastric bypass surgery include an anastomotic leak (a leak where the stomach pouch and small intestine are joined), bleeding, blood clot, narrowing or obstruction at the site of the pouch and intestine junction, and infection. Malabsorption may lead to nutritional deficiency in Iron, Vitamin B12, Calcium, and Folate. These nutritional deficiencies can be avoided by taking supplements and having a diet rich in fruits and vegetables. Dumping syndrome may occur when food moves too quickly from the stomach to the small intestine. This rapid emptying can cause symptoms like nausea, cramps, explosive diarrhea, and dizziness shortly after eating, as well as low blood sugar a few hours later. If the surgery was laparoscopic, the surgeon’s experience and adverse effects during the surgery are the biggest risk factors. 

    After gastric bypass surgery, patients typically face dietary restrictions, including eating smaller portions, avoiding high-sugar or high-fat foods, and chewing food thoroughly to prevent discomfort or complications like dumping syndrome. These changes can lead to a decreased enjoyment of eating, as the body adjusts to a reduced ability to tolerate certain foods and larger meals.

SUMMARY KEY POINTS

In summary, both fat freezing and gastric bypass offer effective solutions for fat reduction and weight loss but they are significantly different in terms of procedure, recovery, and results. Fat freezing is a non-invasive treatment with minimal downtime, making it ideal for those looking to target specific areas of stubborn fat. Gastric bypass/ Roux-en-Y gastric bypass is a more invasive procedure that leads to significant weight loss over time but requires a longer recovery period and lifestyle changes. It's essential to consult with healthcare providers to receive personalized advice based on individual health needs, goals, and lifestyle. Take the time to evaluate your options and align them with your unique circumstances.

CONCLUSION

FAQs for Fat Freezing and Gastric ByPass

  • Yes, gastric bypass surgery can improve or even reverse fatty liver disease because significant weight loss reduces liver fat and improves liver function.

  • No, you won’t be able to eat the same way as before due to the reduced stomach size and changes in digestion. While you can gradually return to a normal variety of foods, portion sizes, and food choices will be limited.

  • Yes, many patients report being able to enjoy food again after gastric bypass, but it may be in smaller quantities and with more careful choices.

  • While there's no absolute ban on specific foods, it is better to avoid certain foods that are harder to digest post-surgery, such as high-sugar, high-fat, or fried foods.
