As with any medical procedure, it is to be expected that questions and concerns may arise about what to expect before, during and after surgery. At Western Bariatric Institute, we believe in putting our patient’s minds at ease. We assure you that there will be plenty of time to ask questions if and when you decide that weight loss surgery is the right choice for you, but in the meantime, we have compiled a few of the most commonly asked questions that we believe are the most helpful in your path to making your decision.
Understanding Bariatric Surgery
Bariatric surgery refers to a group of surgical procedures that help people with morbid obesity lose weight by altering the digestive system. These procedures reduce the size of the stomach and, in some cases, reroute the intestines to limit calorie intake and absorption and influence hunger‑related hormones. Bariatric surgery is one of the most effective long‑term treatments for significant weight loss and can improve many obesity‑related conditions.
Minimally invasive surgery, including laparoscopic or robotic techniques, uses small incisions and specialized instruments. This approach typically results in less pain, shorter hospital stays, faster recovery, and smaller scars compared with traditional open surgery. Your surgeon will explain which approach is best for you.
Most patients qualify for bariatric surgery if they have a BMI of 40 or higher, or a BMI of 35 or higher with obesity‑related health conditions such as type 2 diabetes, high blood pressure, or sleep apnea. Your surgeon and care team will assess your overall health, weight history, and readiness for surgery.
Pre-Surgery Preparation
Many health plans cover weight loss surgery when medical criteria are met. Insurance requirements often include documentation of prior weight loss attempts, medically supervised diet participation, and completion of education modules. Our patient advocates will help you verify your benefits and understand your plan’s requirements. Some patients choose self‑pay if insurance does not cover surgery.
Yes. Most patients follow a pre‑operative diet to help lower surgical risk and reduce liver size. This may include a medically supervised diet and specific nutritional guidelines. Your patient advocate and dietitian will walk you through the requirements.
Before surgery, you’ll complete medical evaluations, lab work, nutrition counseling, and education classes like “Steps to Success.” These steps prepare you physically and mentally for surgery and help increase your chances of long‑term success.
Most patients complete the necessary requirements and receive a surgery date within 2–3 months, but some insurance plans may require longer documentation or waiting periods.
Surgery & Recovery
Hospital stays vary depending on the procedure and your overall health. Many patients stay one to three days before going home with specific recovery instructions from your surgeon and care team.
Most patients return to light activity or work within 1–2 weeks after surgery. Full activity and heavy lifting are typically postponed for about 4–6 weeks while your body heals. Your surgeon will provide personalized guidance.
Post-Surgery Lifestyle & Nutrition
Some patients experience temporary hair shedding during the rapid weight loss period. It’s usually short‑lived and related to changes in nutrition and protein intake. Adequate protein and vitamin intake, as recommended by your care team, can help minimize hair loss.
Yes. Most bariatric procedures, especially gastric bypass, require lifelong vitamin and mineral supplementation to prevent deficiencies due to reduced food intake and absorption. Routine blood work helps guide ongoing supplement needs.
Yes — but it’s typically recommended to wait at least 12–18 months after surgery before becoming pregnant to ensure that weight loss has stabilized and nutritional needs are met. Your obstetrician and bariatric surgeon can help plan for a healthy pregnancy.
Some patients choose plastic surgery to remove excess skin after significant weight loss. This is a personal choice and often not covered by insurance. Your surgeon can discuss options and referrals if desired.
Long-Term Results & Maintenance
Follow‑up care is a lifelong partnership. You’ll have several visits in the first year — including 1 week, 1 month, 3 months, 6 months, and annual check‑ups afterward — with possible additional visits depending on your needs.
Weight loss varies by person and procedure. Many patients lose a significant amount of excess body weight in the first year following surgery, especially when combined with dietary changes and physical activity. Your surgeon will discuss realistic expectations based on your specific situation.
Yes, weight regain is possible if healthy eating habits, exercise, and follow‑up care are not maintained. Bariatric surgery is a tool, and long‑term success depends on lifestyle changes and ongoing support.
