Membuka Misteri Obesitas Visceral: Mengapa Operasi Tidak Cukup

Visceral fat isn’t just a passive layer of storage. It’s metabolically active and releases hormones and chemicals that can interfere with your body’s normal functions. High levels of visceral fat are linked to an increased risk of serious health problems, such as:

• Heart Disease: Visceral fat contributes to inflammation and can lead to the buildup of plaque in your arteries, increasing the risk of heart attack and stroke (SpringerLink).
• Type 2 Diabetes: It’s associated with insulin resistance, making it harder for your body to regulate blood sugar levels.
• High Blood Pressure: Excess visceral fat puts more strain on your cardiovascular system, raising blood pressure.
• Fatty Liver Disease: The fat surrounding the liver can lead to its dysfunction and even liver scarring (cirrhosis) over time.

Prosedur seperti sedot lemak dan pengencangan perut dirancang untuk menghilangkan lemak subkutan, yang terletak tepat di bawah kulit. Namun, lemak visceral disimpan jauh di dalam rongga perut, di sekitar organ vital, sehingga tidak dapat diakses melalui operasi. Selain itu, beberapa penelitian menunjukkan bahwa sedot lemak dapat menyebabkan peningkatan kompensasi lemak visceral jika tidak dipasangkan dengan aktivitas fisik teratur (Oxford Academic).

While it’s true that liposuction or tummy tuck cannot eliminate visceral fat, they can still play an important role for patients struggling with obesity. People with severe visceral obesity often have a low basal metabolic rate and may find it difficult to achieve significant results from diet and exercise alone. In fact, studies suggest that the success rate for weight loss through lifestyle changes is less than 8% for individuals with obesity.

By removing external fat through procedures like liposuction or tummy tuck, patients can experience a dramatic improvement in their appearance, which can serve as a powerful motivation to adopt healthier habits. This renewed sense of motivation often increases the likelihood of overcoming obesity and maintaining long-term weight management.

Unlike subcutaneous fat, visceral fat isn’t visible from the outside. However, a large waistline can be an indicator. For most people, a waist circumference of more than 35 inches (88 cm) for women and 40 inches (102 cm) for men suggests an unhealthy amount of visceral fat. Body mass index (BMI) can also provide a clue, but it doesn’t distinguish between fat types.

The most accurate way to measure visceral fat is through imaging techniques like CT scans or MRI, but these aren’t commonly used due to their cost and complexity. Instead, doctors may assess risk factors like waist-to-hip ratio and overall lifestyle.

The good news is that visceral fat responds well to lifestyle changes. Here are some effective strategies:

1. Healthy Eating: Focus on a balanced diet rich in fruits, vegetables, lean proteins, whole grains, and healthy fats. Avoid added sugars, refined carbs, and processed foods.
2. Regular Exercise: Aim for at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous exercise per week, combined with strength training.
3. Stress Management: Practice relaxation techniques such as meditation, yoga, or deep breathing exercises.
4. Adequate Sleep: Poor sleep can disrupt hormones that regulate appetite and fat storage. Aim for 7-9 hours of quality sleep each night.
5. Limit Alcohol Consumption: Excess alcohol intake can contribute to weight gain, particularly around the abdomen.

While lifestyle changes are the foundation for reducing visceral fat, additional medical interventions may be necessary for some individuals. Options include:

• Medications and Injections: Prescription medications or injectable treatments like GLP-1 medications have shown effectiveness in reducing visceral adipose tissue (PLOS ONE).
• Behavioral Therapy: Addressing emotional and psychological factors through counseling or therapy can help individuals overcome barriers to weight loss.
• Bariatric Surgery: For those with severe obesity and associated health risks, bariatric surgery, such as gastric bypass or sleeve gastrectomy, may be considered as a last resort to achieve significant weight reduction.
