With the modern era, certain beauty standards have been imposed on people, bringing along many trends that change over time. These standards created widespread perceptions such as “If you don’t have a good body, you won’t be liked” or “You must be thin and fit to be accepted.”
In response, the body positivity movement emerged to challenge these norms. Its original purpose was to encourage people to live comfortably in bodies where they feel healthy. However, over time, this movement has sometimes led to narratives that normalize obesity.
First and foremost, it must be clearly understood: Obesity is not merely an aesthetic concern. It is a chronic disease recognized as the root cause of many serious health conditions. The World Health Organization (WHO) defines obesity as a global epidemic, and numerous scientific studies emphasize the critical importance of early intervention.
So how does obesity affect human health? Let’s take a closer look at five major health risks caused by obesity.
When an overweight person goes for a long walk, they may experience chest tightness and an increased heart rate. As body weight increases, the heart is forced to work harder. Obesity directly threatens heart health.
It contributes to high blood pressure, high cholesterol, and atherosclerosis, weakening blood circulation as heart rhythm becomes impaired. If left untreated, obesity significantly increases the risk of heart attack and stroke. Abdominal fat, in particular, is strongly linked to cardiovascular disease.
The foods we consume directly affect blood sugar levels. Diets rich in carbohydrates, saturated fats, and sugary foods cause rapid spikes in blood sugar. Repeated fluctuations increase the risk of diabetes.
Obese individuals often follow such dietary patterns, which greatly increases the likelihood of developing insulin resistance. Over time, this condition can progress to Type 2 diabetes. If uncontrolled, diabetes may lead to kidney failure, vision loss, and nerve damage.
Returning to the walking example, another common complaint among obese individuals is joint and muscle pain. Excess body weight places significant pressure on the knees, hips, and lower back.
This pressure can result in osteoarthritis, severe back, knee, and joint pain, and reduced mobility. Even simple daily activities—like tying shoelaces—can become difficult.
As heart rate increases during physical activity, breathing becomes more labored. Obesity narrows the airways, making breathing more difficult. The difference in breathing capacity between individuals with normal and high BMI is especially noticeable when climbing stairs.
Irregular breathing, elevated heart rate, and musculoskeletal discomfort together contribute to sleep apnea, a condition common in obese individuals. Sleep apnea causes breathing interruptions during sleep and leads to excessive daytime fatigue.
Obesity affects not only physical health but also mental well-being. Social pressure, low self-esteem, and body image issues often lead to depression, anxiety, and social isolation. Feeling unaccepted by others can be emotionally exhausting over time.
Although the health risks associated with obesity are serious, they can be managed with proper treatment. Healthy nutrition, lifestyle changes, and when necessary, surgical interventions can help individuals regain their health. Early diagnosis and professional support are key in the fight against obesity.
