What to expect at your consultation…

Dr. Thodiyil will review your medical and surgical history in detail and will then examine you. He will then review his findings with you and discuss treatment options and the role of weight loss surgery. He will discuss the surgical options and when appropriate, he will make recommendations for the type of surgery. Dr. Thodiyil will order additional tests and consultations to assess your fitness for surgery. The steps prior to undergoing weight loss surgery are summarized below:

  • Step 1: Attend an Obesity Information Seminar

    Dr. Thodiyil conducts seminars on obesity. You can learn here and watch pre-recorded events on this site. These seminars help people struggling with obesity to be better informed when making decisions about their treatment.

  • Step 2: Initial Office Visit

    You will meet with Dr. Thodiyil for an initial evaluation for bariatric surgery. He will perform a detailed history and examination and discuss the bariatric surgical options. He will be able to tell you if you are a candidate for bariatric surgery and how you are likely to benefit. He will also outline the tests you would need to have prior to surgery.

  • Step 3: Medical Evaluation in Preparation for Surgery

    Persons suffering from severe obesity frequently also have many medical conditions that are caused or aggravated by obesity. Many are even unaware of their medical conditions. It is far safer to identify and treat these well before the day of surgery.


    Medical evaluation is individualized, but would typically include some tests for your heart, your lungs, a sleep study, an upper endoscopy and a number of blood tests. All prospective patients are screened by a psychiatrist to determine that they are psychologically well prepared to undergo what is essentially a life changing experience.

  • Step 4: Improve your lifestyle

    The results of surgery are much better in the patient who has put in the effort to improve exercise and activity levels; made changes to eating and drinking habits; and improved sleeping habits - getting to bed in good time and sleeping 7 to 8 hours a day.

  • Step 5: Final Preoperative Visit; Start of Low Calorie Diet

    Once testing is complete and required paperwork is in order, Dr. Thodiyil will see you to review test results with you and to set a date for your surgery. You may have more questions. He will start you on a low (800 kcal) diet for the two weeks prior to your surgery. This is designed to help you loose 10 to 15 lb so as to reduce the size of your liver and hence make surgery safer and smoother. If you are diabetic, you will need to work closely with your primary care doctor at this point to adjust your diabetic medications to avoid low blood sugar.

  • Step 6: Insurance Precertification

    Once the medical evaluation is complete, Dr. Thodiyil’s office will write to your insurance company with all supporting test results seeking authorization for the bariatric surgery. In most circumstances this proceeds without difficulty.

    Where insurance does not cover the cost of your surgery, payment options will be reviewed.

  • Step 7: Anesthesia Pre-testing

    This will be your final visit to the hospital prior to your surgery. During pre-testing, the anesthesia staff will evaluate your fitness for anesthesia. They will utilize most of the tests you would have undergone up to that point, but will often also include some more up-to-date blood tests.

  • Step 8: The Day Before Surgery

    It is normal to feel nervous. You could carry on with your normal activities. Continue with the low calorie diet. The Operating Room Office will call you, usually in the evening, to confirm the time of your surgery and will advice you about where and when to report. You should be fasted for 8 hours prior to surgery. As a general rule you should continue taking your medications as usual up to the morning of surgery, with the exception of diabetic medications and some blood thinners. You should consult with your primary care doctor or endocrinologist about adjusting your diabetic medications. As a rule oral diabetic medications should NOT be taken on the morning of surgery while long acting insulin may have to be stopped a day before. Some long acting agents such as (e.g. chlorpropamide, Diabinese) are stopped 2 to3 days prior to surgery.

  • Step 9: Your Surgery!

    On the evening of surgery, your nurse will help get you out of bed and walk about on the ward. This will reduce the chance of getting a blood clot. You will have an IV drip; you will start drinking water 6 hours after surgery. Whether you have had a sleeve gastrectomy or a gastric bypass, you can expect to be discharged home the day after surgery on a liquid diet.

  • Step 10: Follow-up

    The first follow-up visit is at one week after surgery and will then be seen at 1, 3, 6, 9, 12 and 18 months and then on an annual basis. The follow up visits are with Dr. Thodiyil and the nutritionist.

    By the 12th month, some patients may need a referral to a plastic surgeon for issues with skin.

  • Step 11: Support Group Meetings

    Patients who have undergone bariatric surgery are encouraged to attend our support group meetings. These meetings are designed to bring together people who are adjusting to their new life styles after bariatric surgery. This would be a place where tips are exchanged and where one hears the ups and downs of those who have gone through it all before.
