If you experience heartburn at least two to three times a week, you may have gastroesophageal reflux disease, or GERD. You can get GERD test and if the test comes negative , their are a series of other tests you need to undergo
a few other tests that I have mentioned below:
Abdominal ultrasound
Blood studies including a complete blood count (CBC), blood urea nitrogen (BUN), cortisol, creatinine, electrolytes, prolactin and thyroid-stimulating hormone (TSH)
Cardiac catheterization
Chest X-ray
Colonoscopy
Pelvic ultrasound
Pulmonary function tests
Treadmill stress test if able to exercise or persantine thallium scan
Echocardiogram
Electrocardiogram (EKG)
Flexible sigmoidoscopy
Mammogram
Pap smear
If you pass these tests, then you are qualified for a lap band surgery
