FAQ

  • What can I expect after Bariatric Surgery?

    You can expect to lose between 65% and 100% of your excess weight in 12 months.

    This weight loss helps improve pre-existing medical conditions and prevent other diseases.

  • How long after bariatric surgery will I have to be out from work?

    If your job is not physically demanding you can return within 3 days after a gastric band, 6 days after a gastric sleeve and 7 days after a gastric bypass and metabolic surgery.

    If your job is physically demanding and requires heavy lifting or physical activity, a longer period off work may be necessary.

  • When can I start exercising again after surgery?

    You can usually begin within 15 days.

    Take care of your joints (knees and ankles) when you workout. To reduce pressure on your joints we recommend a stationary bike, elliptical machines, water aerobics or walking under water (remember to wait 15 days after surgery to immerse in water).

  • Can I have a bariatric procedure if I had another abdominal procedure in the past?

    Depends on the specific case. It is important to recall all prior surgeries and let Dr. Rumbaut or our team know during the evaluation process.

  • Will Bariatric Surgery help improve my type 2 diabetes?

    Metabolic Surgery has been shown to improve glucose homeostasis more effectively than any know pharmaceutical or behavioral approach.

  • Can I have bariatric surgery if I have heart disease?

    Yes, surgery leads to significant improvement in conditions associated with or contributing to heart disease, including lipid abnormalities, an enlarged heart, vascular and coronary disease and hypertension. However, if you have heart disease, you will need medical clearance for bariatric surgery from our cardiologist and Dr. Rumbaut.

  • Can I have a normal pregnancy after a bariatric procedure?

    Yes. After a gastric sleeve procedure and the Lap band procedure you can get pregnant immediately without any risk, but it is recommended to wait until you have reached your ideal weight.

    Gastric bypass patients need to wait 18 months before getting pregnant, because of the risk of vitamin and nutrient deficiencies.

    Studies find that women who had bariatric surgery have improved pregnancy and offspring outcomes than those who are affected by severe obesity and have not had bariatric surgery. These improvements include a reduced rate of preeclampsia (an increase in blood pressure leading to chronic high blood pressure) and gestational diabetes, a lower incidence of stillbirths, and fewer miscarriages.

    The offspring of bariatric surgery patients are also less likely to be underweight or overweight at the time of birth.

  • Will I have excess skin after bariatric surgery?

    This depends on your genetics, how much weight you lose, your age, If you smoke, sun exposure and whether or not you exercise

    It is recommended to drink plenty of water after the procedure to maintain skin elasticity and to eat enough protein and do weightlifting exercise.

    There are patients who can benefit from excess skin removal plastic surgery. It is recommended to wait at least 18 months before having plastic surgery.

  • Will I lose my hair after bariatric surgery?

    Some patients temporarily lose some hair between the sixth and ninth months following a gastric bypass procedure.

    In your post-op visits with Dr. Lizcelly, specialist in bariatric nutrition, adjustments are made to your intake of protein, vitamins and minerals to prevent hair loss and ensure hair re-growth.

    It is important to know that hair loss from nutritional causes is only temporary and reversible.

  • Will I have to take vitamins and minerals?

    Vitamin and mineral supplements are recommended after any bariatric procedure but are only required after a Gastric Bypass procedure.

  • Will I have to follow a special diet before a bariatric procedure?

    Yes, in order to shrink the liver and reduce fat in the abdomen. This greatly helps with surgery and recovery.

  • Will I have to follow a diet and exercise plan after a bariatric procedure?

    Yes. Surgery is just a tool that will enable you to lose weight. Although surgery does produce changes in your body that help with the initial weight-loss and maintenance of the weight-loss, it is ultimately up to you to make lifelong changes to be successful. This includes making right food choices, controlling portions, taking vitamin and mineral supplements as directed, getting plenty of fluid, rest and regular exercise. In addition, sufficient sleep and stress control may help to improve long-term weight-loss success and maintenance.

    Without these lifelong changes weight regain is likely to occur.

  • Can I go off some of my medications after bariatric surgery?

    With weight-loss you may be able to go off or reduce the dosage of many of the medications you take for obesity-associated co-morbidities, such as blood pressure, heart disease, arthritis, lipid abnormalities, and type 2 diabetes.

    It is important that you talk with our team or your Primary care Physician before making any dosage modification.

  • What are the risks of undergoing a bariatric procedure?

    Like any surgery, a bariatric procedure has risks, some serious, some inconvenient.

    Risks depend on your over all health, type of procedure and surgeon's experience.

    It's important to discuss these risks with your surgeon directly.

  • Can I reach my goal weight with only diet and exercise?

    Yes, you can. But for people that suffer severe obesity it is extremely difficult to reach their goal with only diet and exercise. When you undergo a calorie restrictive diet for a long period of time your body makes biological changes that reduce metabolism and increase calorie absorption and hunger making it very difficult to stay on track.

    When you finish a period of dieting some biological changes are triggered. Slower metabolism, increase in fat storage capacity and deterioration of the fat burning process occur. Which causes you to gain even more weight than what your originally started with.

    The National Institutes of Health (NIH) recognizes that long-term weight loss for people suffering from severe obesity is only probable through bariatric surgery.

    According to scientific studies, only 5% of people who diet are able to maintain long-term weight loss (3-5 years).[1] [2]

    Compared to 5% of the diets, 90% of bariatric patients maintain long term weight loss of over 50% of their overweight. [3]

  • How will alcohol affect me?

    Alcohol sensitivity (particularly if consumed during the weight loss period) increases.

    The effect of alcohol is greater after a bariatric procedure.

    So certain precautions are recommended:

    • • Avoid alcohol consumption during the rapid weight loss period.

    • • Understand that even small amounts can cause intoxication.

  • Does Dr. Rumbaut perform the gastric plication?

    No. The gastric plication is a new procedure and there isn´t enough data available at this time to draw any definitive conclusions regarding the safety and efficacy of this procedure.

    It is a procedure that the ASMBS (highest authority in bariatric procedures) considers investigational at this time. They strongly suggest that doctors should share this information with patients:

    Here are the url from ASMBS with more information.

  • Can I have health problems caused by deficiencies of vitamins and minerals?

    Bariatric procedure can cause deficiency in vitamins, minerals and proteins.

    These can cause fatigue, anemia, loss of bone and muscle, impaired night vision, low immunity, loss of proper nerve function and even cognitive defects.

    Proper diet and supplements prevent and reverse all deficiencies.

    A special diet before and after surgery is necessary. Nutrient levels are monitored by Dr. Lizcelly (specialized in bariatric nutrition).

  • Bariatric surgery has grown rapidly in recent years. With so many surgeons to choose from, what is the most important information I should consider?

    1. Experience:Data suggests that complication rates (including mortality) is directly related to the number of bariatric procedures performed.
