Diagnosis and Evaluation

The Clinical Evaluation Process

The journey toward a surgical weight loss solution begins with a rigorous and multidisciplinary evaluation. This is not a standard checkup; it is a specialized diagnostic phase designed to ensure that the patient is a safe candidate for the procedure and that the long-term results will be sustainable. At Liv Hospital, we follow a structured protocol where specialists from various fields collaborate to assess your health. This baseline data is essential for measuring your progress after the operation and for identifying any underlying issues that need to be optimized before you enter the operating suite.

Nutritional Status Assessment

Sleeve Gastrectomy

A fundamental part of the diagnosis is the nutritional evaluation. A clinical dietitian will review your dietary history and current eating patterns.

  • Evaluation of vitamin and mineral levels through blood tests.
  • Identification of “grazing” or emotional eating behaviors.
  • Education on the post-operative diet phases.

The goal is to ensure you do not have any pre-existing deficiencies (such as low iron or B12) that could be exacerbated after the Sleeve Gastrectomy. This assessment also helps the team predict how your body will handle the transition to much smaller portion sizes.

Upper Gastrointestinal Endoscopy

resized 34 LIV Hospital

Because the surgery involves stapling and removing a large part of the stomach, the health of the gastric lining must be confirmed visually.

  • An endoscopy involves passing a thin camera through the mouth.
  • It identifies stomach ulcers or severe inflammation (gastritis).
  • it checks for the presence of a hiatal hernia.
  • It screens for H. pylori infection, which must be treated before surgery.

Visualizing the internal environment ensures that the surgeon is working on healthy tissue, which is vital for the integrity of the staple line and the overall safety of the operation.

Cardiovascular and Pulmonary Clearance

Surgery under general anesthesia requires that the heart and lungs are in peak condition.

  • Electrocardiogram (ECG) to check heart rhythm.
  • Stress testing for patients with high cardiovascular risk factors.
  • Pulmonary function tests to evaluate lung capacity.
  • Chest X-ray to assess the size and position of the heart and lungs.

Ensuring that your circulatory and respiratory systems can handle the temporary stress of the operation is a top diagnostic priority at Liv Hospital. If any risks are detected, our medical team will work to stabilize these systems before the procedure is scheduled.

Laboratory Blood Panels

A wide range of blood tests is performed to create a comprehensive “metabolic snapshot” of your health.

  • Complete Blood Count (CBC) to check for anemia or infection.
  • Comprehensive Metabolic Panel (CMP) for liver and kidney function.
  • Lipid profile (cholesterol and triglycerides).
  • Fasting blood glucose and HbA1c to determine the status of diabetes.

These biological markers are essential for tracking the resolution of metabolic conditions after the Sleeve Gastrectomy. Watching these numbers return to the healthy range is one of the most rewarding aspects of the recovery journey.

Psychological and Behavioral Evaluation

Bariatric surgery is as much a mental journey as a physical one. A psychological assessment is a standard clinical requirement to ensure long-term success.

  • Assessing your motivation and readiness for permanent lifestyle change.
  • Identifying any untreated depression or anxiety disorders.
  • Evaluating your support system at home.

The purpose is to ensure that you have the emotional resilience to adhere to the strict guidelines required for the tool to work effectively. Patients who are mentally prepared are statistically more likely to reach their target weight and maintain it for decades.

Body Composition Analysis

To move beyond just the number on the scale, we often use advanced body composition tools.

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

This diagnostic data helps our team at Liv Hospital tailor your post-surgical exercise and nutrition plan. It ensures that the weight you lose after your Sleeve Gastrectomy comes primarily from fat stores rather than muscle tissue, which is vital for maintaining a healthy metabolism.

Sleep Study (Polysomnography)

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

  • Monitoring breathing patterns and oxygen levels overnight.
  • Determining the severity of any airway obstructions.
    If sleep apnea is detected, you may be started on a CPAP machine before surgery.

This simple diagnostic step significantly reduces the risk of respiratory complications during anesthesia and the early recovery phase, ensuring a much safer surgical experience.

Thyroid and Endocrine Screening

In some cases, weight gain can be exacerbated by an underlying hormonal imbalance.

  • Testing for hypothyroidism (underactive thyroid).
  • Assessing cortisol levels to rule out adrenal issues.
  • Evaluating reproductive hormones in women (screening for PCOS).

If a hormonal issue is contributing to your condition, it must be addressed medically alongside the surgical intervention. This comprehensive approach ensures that we are treating the root cause of the problem, not just the symptoms, for a more successful recovery.

Final Diagnostic Synthesis and Consent

At the conclusion of the evaluation phase, the bariatric team meets for a “case conference” to review all your test results. You will then meet with your surgeon for a final consultation. During this session, the visual findings from your endoscopy and the data from your lab work are explained in detail. At Liv Hospital, we believe in a transparent and informed diagnostic process. If you are ready to take control of your health, we encourage you to schedule a comprehensive evaluation to secure your visual and physical future.
