What is Obesity?

Obesity is a chronic health condition resulting from various factors that contribute to an excessive accumulation of body fat, leading to potential health issues. 

While body fat is not a disease, an excess can alter bodily functions, causing progressive changes with negative health effects over time. 

The encouraging aspect is that reducing excess body fat can mitigate health risks significantly. Implementing even minor weight changes can yield substantial health improvements. 

It's essential to recognize that effective weight loss methods vary among individuals, and sustaining weight loss is as vital as achieving it initially.

Types of Obesity

Healthcare providers categorize obesity into three classes based on Body Mass Index (BMI), which determines the severity of the condition:

Class I obesity: BMI 30 to <35 kg/m².

Class II obesity: BMI 35 to <40 kg/m².

Class III obesity: BMI 40+ kg/m², also known as morbid or severe obesity.

In addition to BMI classifications, obesity can be categorized based on fat distribution:

Peripheral obesity: Excessive fat in hips, thighs, and buttocks.

Central obesity: Excessive fat around the abdomen, increasing the risk of diabetes, high blood pressure, heart disease, kidney disease, and certain cancers.

Combination obesity: Accumulation in both peripheral and central regions.

Moreover, obesity is classified by its association with diseases:

Type 1 obesity: Caused by excessive calorie intake and inadequate physical activity.

Type 2 obesity: Resulting from conditions like hypothyroidism, Cushing’s syndrome, polycystic ovary syndrome, and insulinoma.

Finally, obesity types based on fat cell characteristics include:

Hypertrophic obesity: Increase in adipose cell size, prevalent in adults.

Hyperplastic obesity: Increase in the number of fat cells, predominant in children.

Causes of Obesity

Obesity results from an energy imbalance, where your body accumulates excess fat due to consuming more calories than needed. This imbalance increases the risk of obesity development. Multiple factors contribute to this caloric surplus, ranging from individual behaviors to societal structures.

1. Dietary Habits

• Consumption of fast and convenience foods high in sugar and fat.
• Foods lacking in fiber and nutrients lead to increased hunger.
• Advertising promotes addictive eating patterns.

2. Psychological Factors

• Boredom, loneliness, anxiety, and depression contribute to overeating.

3. Hormonal Influence

• Disruptions in hunger and satiety signals due to factors like stress and lack of sleep.
• Certain medications, such as antidepressants and steroids, may contribute to weight gain.

4. Environmental and Lifestyle Factors

• Monitoring changes, with measurements is recommended at least once a year.

Evaluation for Other Health Problems

• Investigating existing health issues and assessing potential concerns.

Medication

Consideration of medications complements other treatments, with FDA-approved drugs like appetite suppressants and fat absorption inhibitors playing a role. Medications are viewed as part of a comprehensive strategy rather than standalone solutions.

Weight Loss Surgery

Reserved for individuals with class III obesity, surgical options include gastric sleeve, gastric band, gastric bypass, and duodenal switch. Surgery alters digestive processes, limiting calorie intake, and affecting metabolism.

Comprehensive Health Profile

Continuous assessment of an individual's health story and response to interventions guides ongoing adjustments. The recognition that everyone responds differently underscores the effectiveness of team-based programs with frequent, personalized communication.

Monitoring Health Risks

Regular monitoring of BMI, waist circumference, and other health indicators is emphasized. Proactive management of associated health problems, such as high blood pressure and diabetes, is crucial. Addressing obesity-related symptoms and complications is given utmost importance.

Through these treatments, healthcare providers offer effective and sustained obesity treatment. Regular monitoring and personalized adjustments ultimately contribute to long-term weight management and overall health improvement.
