There’s a common misconception that obesity is just about eating too much or not exercising enough, but the reality is much more complex.

Obesity is a chronic disease, caused by a range of factors that go beyond what you eat and how you move. Your genetics, your environment, and even your mental health all play a role in how your body stores fat and regulates hunger.

Understanding these causes is crucial for anyone trying to manage their weight or considering bariatric surgery. Diagnosing obesity is complex also.

The Role of Genetics in Obesity

Your genetics can significantly impact your risk of developing obesity. Studies show that people with a family history of obesity are more likely to develop the condition themselves. Genetics influence how your body stores fat, how quickly you feel full after eating, and how your body responds to changes in your diet.

However, it’s important to remember that while genetics can increase your risk, they don’t determine your destiny.

Environmental factors and lifestyle choices still play a major role in weight management.

Stress and Psychological Factors

There’s a strong connection between mental health and obesity.

Stress, anxiety, and depression can increase the likelihood of overeating, especially when combined with emotional eating habits.

Chronic stress raises levels of cortisol, a hormone that makes you feel hungrier and more likely to crave foods high in fat and sugar.

Over time, these patterns can lead to weight gain. Managing stress through techniques like mindfulness or therapy is a key component of weight management.

Appetite and Hormones

Obesity is also linked to hormonal imbalances that affect appetite regulation.

Hormones like ghrelin (which stimulates hunger) and leptin (which signals fullness) may not work as effectively in people with obesity.

This makes it harder to feel satisfied after meals, leading to overeating. Stress, poor sleep, and certain medical conditions can further disrupt these signals, creating a cycle that’s difficult to break.

Where You Live, Work, and Play

Your environment also plays a critical role in your risk of developing obesity.

If you live in a neighbourhood where fresh, affordable food is hard to come by—known as a “food desert”—you may rely on processed or fast foods, which are often high in calories and low in nutrients.

Similarly, living in areas without access to parks, walking paths, or gyms can make it harder to stay active. Even your workplace can influence your weight, especially if you have a sedentary desk job.

The importance of understanding obesity holistically

Obesity is a complex condition influenced by more than just food and exercise. Genetics, mental health, and the environment all play significant roles in how the body regulates fat and hunger.

While factors like stress, hormonal imbalances, and limited access to healthy food options can increase the risk of obesity, understanding these underlying causes can help those considering treatment options, including bariatric surgery.

It’s essential to approach obesity with a holistic understanding that goes beyond common misconceptions.
