Diagnosis and Evaluation

The Comprehensive Pre-Operative Exam

The journey toward a surgical weight loss solution begins with a rigorous diagnostic evaluation. This is not a standard check-up; it is a specialized clinical assessment designed to ensure that the patient is a safe candidate for the procedure and that the results will be sustainable. At Liv Hospital, we follow a multidisciplinary approach where experts from different fields collaborate. This ensures that no underlying health issue is overlooked and that the patient’s body is fully prepared for the transition to a restrictive eating pattern.

Nutritional Status Evaluation

A fundamental part of the diagnosis is the nutritional assessment. A clinical dietitian evaluates the patient’s current eating habits, food triggers, and metabolic needs.

Assessment of current vitamin and mineral levels.
Identifying patterns of emotional or “grazing” eating.
Education on the post-surgical diet requirements.

The goal is to ensure the patient doesn’t have existing deficiencies (like low B12 or Vitamin D) that could be exacerbated after the surgery. This evaluation also helps the team predict how the patient will handle the small pouch size created by the banding device.

Gastrointestinal Health Screening

Because the device will be placed around the top of the stomach, the health of the esophagus and stomach must be confirmed.

Screening for severe acid reflux or GERD.
Checking for a hiatal hernia (where part of the stomach slides into the chest).
Ruling out stomach ulcers or active infections like H. pylori.

In some cases, a specialist may perform an upper endoscopy to visualize the stomach lining directly. If a hiatal hernia is found, it can often be repaired at the same time the band is placed, ensuring a better functional result.

Cardiovascular And Pulmonary Clearance

Surgery requires general anesthesia, making cardiovascular and lung health a top diagnostic priority.

Electrocardiogram (ECG) to check heart rhythm.
Chest X-ray to assess lung and heart size.
Blood pressure monitoring under stress.
Pulmonary function tests for patients with a history of smoking or asthma.

These tests ensure that the patient’s heart and lungs can safely handle the surgical process. If any risks are detected, the medical team at Liv Hospital will work to optimize these systems before the operation proceeds.

Laboratory Blood Panels

A wide range of blood tests is performed to create a metabolic baseline.

Comprehensive Metabolic Panel (CMP) to check liver and kidney function.
Lipid profile (Cholesterol, LDL, HDL, Triglycerides).
Fasting glucose and HbA1c to screen for or monitor diabetes.
Complete Blood Count (CBC) to check for anemia or infection.

These biological markers are essential for tracking the patient’s progress after the banding. One of the most rewarding aspects of bariatric care is seeing these metabolic numbers return to the healthy range as the patient loses weight.

Psychological And Behavioral Assessment

Weight loss is as much a mental journey as a physical one. A psychological evaluation is a standard clinical requirement for bariatric surgery.

Assessing the patient’s motivation and expectations.
Screening for depression, anxiety, or disordered eating.
Evaluating the patient’s social support system.

The purpose is to ensure the patient has the emotional resilience to adhere to the strict post-operative guidelines. Patients who are mentally prepared are significantly more likely to achieve their weight loss goals and maintain them for the long term.

Body Composition Analysis

To move beyond just the number on the scale, specialists at Liv Hospital often use body composition analysis.

Measuring the ratio of fat mass to lean muscle mass.
Identifying visceral fat (the dangerous fat around organs).
Calculating the Basal Metabolic Rate (BMR).

This diagnostic data helps the team tailor the patient’s exercise and nutrition plan. It ensures that the weight lost after the banding procedure comes from fat stores rather than muscle tissue, which is vital for maintaining a healthy metabolism.

Thyroid And Endocrine Screening

In some cases, obesity may be worsened by an underlying hormonal imbalance.

Testing for hypothyroidism (underactive thyroid).
Assessing cortisol levels to rule out Cushing’s Syndrome.
Evaluating reproductive hormones in women (screening for PCOS).

If a hormonal issue is the primary cause of weight gain, it must be addressed medically alongside the surgical banding. This comprehensive diagnostic approach ensures that we are treating the root cause of the problem, not just the symptoms.

Sleep Study (Polysomnography)

Given the high prevalence of sleep apnea in the bariatric population, a sleep study is often recommended.

Monitoring breathing patterns and oxygen levels overnight.
Determining the severity of airway obstruction.

If sleep apnea is detected, the patient may be started on a CPAP machine before surgery. This improves the safety of the anesthesia and ensures that the patient’s body is well-oxygenated during the critical early recovery phase.

Final Diagnostic Review And Consent

Once all the tests are completed, the bariatric team meets for a “case conference” to review the findings. The patient then meets with the surgeon for a final consultation. During this meeting, the diagnostic results are explained clearly, and the patient is given the opportunity to ask questions. At Liv Hospital, we believe in an informed and collaborative diagnostic process. If you are ready to take the next step toward a healthier life, we encourage you to schedule a comprehensive evaluation to secure your visual and physical future.
