Frequently asked
QUESTIONS

What are the routine tests before surgery?

Routine tests performed include a complete blood count, chemistry panel, lipid profile, thyroid function tests, iron, vitamin levels, liver function tests, clotting profile and urine analysis. A chest X-Ray and pulmonary function tests will be ordered to determine the health status of your lungs, as well as an electrocardiogram to determine if your heart is strong and prepared to handle the stresses associated with surgery. A psychological evaluation, nutritional consult and exercise evaluations are also performed. Ultrasound may be performed in some patients. Selective patients may require sleep study, specialist evaluations and endoscopy.

What is the purpose of all these tests?

An accurate assessment of your health is required before undertaking any surgery. The best way to avoid a complication during and after surgery is to know your state of health prior to having the surgery and optimizing your health to the best state possible prior to the surgery.
We will evaluate and determine if your thyroid function is adequate because untreated hypothyroidism can lead to sudden death following surgery. We also look for signs of diabetes, liver malfunction, breathing difficulties, excess fluid in the tissues, abnormalities of the salts and minerals in body fluids, and abnormal blood fat levels. Some of these laboratory and diagnostic tests will help validate co-morbidities and improve your chances to gain insurance approval.

Do I need endoscopy prior to surgery?

Not all patients will be required to have an endoscopy but when it is determined necessary it must be performed prior to having your surgery. Patients who have significant gastrointestinal (GI) symptoms such as upper abdominal pain, heartburn, belching sour fluid may have serious underlying problems, such as a hiatus hernia, gastro esophageal reflux, or a peptic ulcer. Patients having symptoms of gastric reflux may have early changes in the lining of the esophagus that could predispose them to cancer. It is important to identify these changes so that a suitable surveillance program can be planned for the future. If required your endoscopies will be scheduled with Dr. Mora.

Why might I need a Sleep Study?

Some patients experience signs and symptoms of sleep disorders and are not aware that a problem may exist. The sleep study detects a tendency for abnormal cessation of breathing associated with airway obstruction when the muscles relax during sleep. This condition is referred to as Sleep Apnea. After surgery you will receive sedatives and medications that will help control your pain. Pain medication can depress your normal respiratory drive and protective reflexes, therefore increasing the possibility of an airway obstruction. Sleep Apnea can make this situation life threatening. Undiagnosed and untreated sleep apnea will increase the complication rate significantly. We need to have a clear picture of what to expect prior to your surgery in order to prevent, or better handle a complication if it should arise. Our office can assist you with arrangements to have the sleep study performed quickly.

Why do I need a Psychological Evaluation?

We do not believe that people with weight problems are crazy! The psychological evaluation helps determine your understanding and knowledge of the surgery, and ability to follow the basic post-operative weight loss plan. Many insurance companies require the evaluation prior to giving approval for surgery. Most importantly, you will find that the psychologist may be helpful in defining your personal goals and expectations.
