Obesity is more than just a matter of appearance; it is a silent threat with long-term health risks, including diabetes, hypertension, and heart disease. Fortunately, safe and effective medical treatments are available today. Under the guidance of a doctor, you can receive a treatment plan tailored to your specific needs. This article explores treatment options in detail and provides a guide for sustainable, long-term health.

What Is Obesity? 

Obesity is a condition characterized by the accumulation of body fat beyond normal levels, affecting both physical and mental health. Far more than just a matter of appearance, it significantly increases the risk of serious chronic diseases, including diabetes, hypertension, and heart disease. 

Generally, doctors assess obesity using the Body Mass Index (BMI), which measures the relationship between an individual’s weight and height.

How Is Obesity Measured? Understanding Body Mass Index (BMI)

Body Mass Index (BMI) is a tool used to determine if an individual’s weight falls within a healthy range. It is calculated using the formula: Weight (kg) ÷ Height (m)². For the Thai population, a BMI over 25 is classified as obese, while a BMI over 30 is classified as severely obese.

The Difference Between “Overweight” and “Obesity”

While the terms are often used interchangeably in casual conversation, clinical guidelines provide a clear distinction based on health risk levels:

  • Overweight (BMI 25.0–29.9): Defined as having an excess amount of body weight that may include muscle, bone, fat, and water. While it indicates a weight above the “normal” range, it serves as a primary warning sign for potential metabolic health risks.
  • Obesity (BMI 30.0 and above): Defined specifically as an excessive accumulation of body fat that presents a significant risk to health. At this level, the probability of developing chronic conditions—such as Type 2 diabetes, hypertension, and cardiovascular disease—increases substantially.

Health Issues Related to Weight Gain and Obesity Complications

Obesity can impact multiple systems throughout the body. It may affect the cardiovascular system, increasing the risk of heart disease and stroke. Furthermore, it impairs blood sugar regulation, leading to a higher risk of type 2 diabetes. Additionally, obesity is a known risk factor for certain types of cancer. Maintaining a healthy weight and consuming a nutrient-dense diet can help reduce cancer risks.

In addition, obesity can impact the digestive, gynecological, and reproductive systems. It is also linked to obstructive sleep apnea and osteoarthritis. Maintaining a healthy weight and seeking professional medical care can significantly reduce these risks. For individuals living with obesity, consulting a doctor and achieving a healthy weight are essential steps in lowering the risk of these complications.

How Obesity is categorized

Obesity is categorized into several classes based on BMI standards:

  • Class 1 (25–29.9): Moderate risk of chronic conditions, such as fatty liver disease or mild hypertension.
  • Class 2 (30–34.9): Increased risk of serious diseases, such as type 2 diabetes.
  • Class 3 (≥35): Also known as “Morbid Obesity,” this is a severe stage with a high risk of complications, including sleep apnea, heart disease, and osteoarthritis.

Obesity: Understanding Causes, Identifying Symptoms, and Enhancing Prevention

Obesity comes from a combination of factors, including genetics, hormones, and lifestyle habits. When the body consistently receives excess calories than it needs, fat accumulates beyond its natural limits. Understanding the causes and symptoms of obesity helps us prevent and manage the condition effectively while choosing the most appropriate personalized health care plan.

Cause of Obesity: Why Do We Gain Weight? 

  1. Genetics

If you have a family history of obesity, your risk may be higher because: 

  • Certain genes influence feelings of “hunger” and “fullness.”
  • Genetics play a key role in your metabolism.
  • Some genes cause the body to store fat more easily than normal

The good news is that even if you have a genetic predisposition, lifestyle changes and behavioral adjustments can always help lower your risk.

  1. Hormonal & Endocrine Factors

Abnormal hormone levels can disrupt weight regulation. Examples include:

  • Hypothyroidism: Slows down the metabolism, making it easier to gain weight.
  • PCOS (Polycystic Ovary Syndrome): Affects insulin levels and how the body processes fat.
  • Insulin Abnormalities: Leads to a risk of insulin resistance, which is closely linked to fat accumulation around the waist.
  1. Behavioral & Lifestyle Factors

These are the factors that are most “within your control.”

  • Overeating: Especially consuming high-calorie foods such as fried food and sugary drinks.
  • Lack of Exercise: Results in excess calories being stored as body fat.
  • Sleep Deprivation: Increases the “hunger hormone” (ghrelin) and decreases the “fullness hormone” (leptin).
  • Stress: Triggers cortisol, a hormone that increases appetite and promotes fat storage.

What Are the Symptoms of Obesity?

Symptoms of obesity manifest in various ways, affecting both physical and mental health. Common symptoms include:

  • Shortness of breath or easy fatigability, even during light activities.
  • Joint pain, particularly in the knees and ankles, due to excessive weight-bearing.
  • Snoring or sleep apnea.
  • Body image issues and low self-esteem, which can lead to depression or anxiety.

Obesity Prevention: Adjusting Diet and Daily Lifestyle Habits

While obesity has many causes, prevention begins with the factors we can control in our daily lives, such as:

  • Choose nutrient-dense foods and avoid processed foods, added sugars, and trans fats.
  • Exercise regularly; you should aim for at least 150 minutes per week of exercise.
  • Ensure adequate rest and practice healthy stress-relief techniques.
  • Get regular health screenings to proactively monitor risk factors and prevent potential health complications.

6 Types of Obesity Categorized by Behavior and Health Conditions

Classifying obesity based on behavioral patterns and physical conditions helps us understand the root cause and choose the most effective treatment. It can be divided into 6 categories:

  1. Dietary Obesity
  2. Stress-induced Obesity
  3. Genetic Obesity
  4. Hormonal Obesity
  5. Inactivity-induced Obesity
  6. Sleep-deprivation & Apnea-related Obesity

How Does Obesity Affect Your Health?

Obesity affects far more than just physical appearance; it significantly impacts the internal functions of various body systems, both physically and mentally. Excess body fat can lead to serious chronic diseases and reduce long-term quality of life. Without proper medical care, it can lead to severe complications that are difficult to manage.

Heart Disease, Diabetes, and Hypertension

Obesity is a primary risk factor for Non-Communicable Diseases (NCDs), including:

  • Cardiovascular Disease: The accumulation of fat in the blood vessels leads to atherosclerosis (clogged arteries), forcing the heart to work significantly harder.
  • Type 2 Diabetes: Excess weight interferes with insulin function, causing blood sugar levels to rise above normal.
  • Hypertension: Increased body weight is directly linked to higher vascular pressure, which elevates the risk of a stroke.

Psychological impact and quality of life

Obesity does not only cause physical sickness; it also has a profound impact on mental health. Many individuals experience low self-esteem and face social pressure or weight-based bullying, which can lead to anxiety, depression, or social isolation. Furthermore, the physical limitations caused by excess weight significantly reduce the ability to perform daily activities, noticeably diminishing overall quality of life.

Risk of Complications

Obesity is also linked to other potentially serious complications, such as:

  • Obstructive Sleep Apnea (OSA) is a dangerous and common condition in overweight individuals where breathing repeatedly stops and starts during sleep.
  • Non-Alcoholic Fatty Liver Disease (NAFLD) is liver fat accumulation unrelated to alcohol use.
  • Osteoarthritis, especially in the knees and hips, which endure constant high-pressure weight-bearing.
  • Infertility in both men and women.
  • Increased risk of certain cancers, including colorectal, breast, and endometrial cancers.

These impacts demonstrate that obesity is a critical health issue that should not be overlooked. Early prevention and treatment are the keys to achieving sustainable long-term health.

Obesity Treatment: Safe Medical Options

Obesity can be treated through various methods, depending on the severity and the individual’s overall health. Current medically approved approaches range from lifestyle changes and medication to non-surgical and surgical treatments. To ensure maximum effectiveness and patient safety, these treatments should always be conducted under the supervision of a medical specialist.

Behaviour Modification

Starting with lifestyle changes is the most important foundation for long-term weight control.

  • Dietary Control: Reduce caloric intake by choosing foods high in fiber, healthy fats, and low sugar, such as vegetables, fruits, nuts, and whole grains.
  • Increased Physical Activity: Engage in activities like brisk walking or cycling for at least 150 minutes per week to boost metabolism.
  • Cognitive Behavioral Therapy (CBT): This psychological approach helps reshape unhealthy mindsets toward food and strengthens long-term motivation for self-care.

Pharmacotherapy (Weight Loss Medication)

If lifestyle changes alone are insufficient, a doctor may consider incorporating medication:

  • Approved Weight Loss Medications: Options include Orlistat or GLP-1 receptor agonists (such as Liraglutide), which help suppress appetite and improve metabolic function.
  • Medication Requirements and Monitoring: The use of weight loss medication must be strictly under medical supervision, with continuous monitoring of weight progress and potential side effects.

Non-Surgical Options

For those who prefer to avoid surgery or are not yet candidates for it, there are several alternatives available:

Gastric Balloon: A procedure where a balloon-like device is placed in the stomach to help you feel full faster. This method is ideal for those looking to lose weight over a short-term period.

Endoscopic Sleeve Gastroplasty: A technique that reduces the size of the stomach using endoscopic suturing. Since it requires no traditional incisions, it allows for a significantly faster recovery.

Bariatric Surgery

For individuals with severe obesity or obesity-related comorbidities, such as Type 2 diabetes, bariatric surgery can be a highly effective long-term solution.

Bariatric Surgery: Weight Loss Method 

Bariatric loss surgery is a highly effective method for treating obesity. It has been a recognized medical practice for over 20 years and is widely accepted globally. For instance, in Australia, more than 10,000 bariatric surgeries are performed annually and are covered by major health insurance programs. Similarly, several European countries offer bariatric surgery free of charge through national healthcare. This is because, in the long run, surgery effectively reduces medical expenses and medication costs associated with obesity-related conditions, such as diabetes, hypertension, and sleep apnea.

Bariatric surgery does more than just reduce numbers on a scale; it can completely transform a patient’s life. In less than a year, you can see dramatic results, dropping from a size XXL to a size M. Furthermore, the health risks and comorbidities associated with obesity, such as diabetes, hypertension, and sleep apnea, may significantly improve or even resolve entirely as a direct result of the weight loss.

Consequently, gastric surgery is a highly effective weight loss solution with proven results in both the short and long term. It significantly reduces medical expenses and improves the patient’s overall quality of life. In Thailand, the most popular and sought-after methods are Gastric Bypass and Sleeve Xtra weight loss surgery.

Additionally, there is the “Overstitch” gastric suturing technique, an innovative method that requires no incisions or surgery on the stomach. This procedure leaves no abdominal scars and allows for a significantly faster recovery. However, weight management and dietary adjustments should always be conducted under the expert guidance of a doctor and medical team. This ensures your safety and provides the appropriate care needed.

How to Select a Personalized Treatment Plan

There is no “one-size-fits-all” solution for obesity. Because everyone has a different level of severity, physical condition, comorbidities, and lifestyle, choosing the right treatment requires a thorough evaluation by a medical team to ensure the best and safest results.

Medical Evaluation

The first step in obesity treatment is a thorough assessment by a specialist. This includes calculating Body Mass Index (BMI), measuring waist circumference, and assessing body fat percentage. Doctors will also screen for comorbidities, such as diabetes, hypertension, or dyslipidemia, to determine the most appropriate treatment plan.

Suitability Based on BMI and Comorbidities

BMI is a key criterion used to evaluate treatment options:

  • Individuals with a BMI between 23–24.9 (Overweight) typically begin with lifestyle modifications and physical activity.
  • Individuals with a BMI of 25 and above (Obesity Classes 1–3), doctors may consider incorporating weight loss medication or non-surgical treatments
  • In cases where the BMI exceeds 35 or is accompanied by severe comorbidities, bariatric surgery may be the safest and most effective long-term option.

Post-Treatment Follow-up

Regardless of the chosen method, continuous follow-up is essential. Doctors will adjust the treatment plan based on the body’s changes and work to prevent complications, such as the Yoyo Effect, where weight is regained after the initial loss.

Holistic Approaches to Overweight and Obesity Management

Effective long-term obesity management should not focus only on weight reduction. Instead, it must address both physical and mental health to foster sustainable and healthy behaviors.

Psychological Support

Managing weight and controlling obesity is a challenging process. Support from a medical team, nutritionists, and psychologists helps patients maintain motivation and avoid feeling isolated. Psychological therapies, such as Cognitive Behavioral Therapy (CBT), are effective in adjusting thoughts and attitudes toward eating and physical activity.

Long-Term Strategies for Sustainable Health

Setting realistic and personalized goals is essential. For instance, a gradual weight loss of just 5–10% of total body weight can significantly reduce the risk of complications. Furthermore, the focus should be on sustainable behavioral changes, such as choosing healthy foods, engaging in enjoyable and consistent exercise, and ensuring adequate rest.

Adopting a holistic view of obesity does more than just lead to successful weight loss; it enhances overall quality of life and promotes long-term health.

Frequently Asked Question 

Can I Treat Obesity On My Own? 

You can begin managing obesity on your own at an initial level by adjusting eating habits and increasing physical activity. However, if you are significantly overweight or have comorbidities such as diabetes and hypertension, you should consult a doctor to create a treatment plan that is both appropriate and safe.

What Should I Do If My BMI Does Not Meet the Criteria for Surgery?

If your BMI has not yet reached the appropriate threshold for surgery, a doctor may recommend other methods, such as behavioral modification, medication, or non-surgical treatments. These alternatives include gastric balloons or endoscopic gastric suturing, which are safe options tailored to the severity of the patient’s obesity.

What Causes the Yoyo Effect After Weight Loss?

The Yoyo Effect occurs when weight is lost too rapidly or through overly restrictive dieting that cannot be sustained long-term. When a person returns to their previous habits, the body tends to store more fat than before. To prevent this, weight loss should be a gradual process focused on building sustainable habits, such as eating a balanced diet and exercising regularly.

Does a Gastric Balloon Truly Help With Weight Loss?

A Gastric balloon procedure is an effective weight-loss solution as it helps patients feel full faster and reduce food intake. It is ideal for those looking to lose approximately 10–15% of their total body weight. While highly effective in the short term, it should be combined with behavioral modifications to ensure sustainable results.

How Long Does It Take to See Results? 

It depends on the method used and each individual’s physical condition. With behavioral modifications, changes typically become noticeable within 3-6 months. In contrast, medical interventions such as medication, gastric balloons, or surgery often show significant results within the first few months. However, continuous follow-up and lifestyle adjustments are essential to maintain weight loss in the long term.

Summary: Obesity Is Treatable With the Right Approach

Obesity is a condition that negatively impacts both physical and mental health. However, the good news is that it can be effectively treated and managed by choosing the right approach for your specific needs. This begins with adjusting eating habits and increasing exercise, alongside a professional evaluation by a specialist. A doctor can help determine the most appropriate option, whether it involves medication, non-surgical treatments, or bariatric surgery.

Long-term weight management relies on consistent clinical care and the establishment of sustainable health behaviors. This approach also reduces the risk of serious diseases associated with obesity. Working together with a medical team, nutritionists, and mental health experts will help enhance your quality of life and promote overall well-being in every aspect.
