Obesity is a complex and multifaceted condition recognised by an excessive accumulation of body fat. Obesity can lead to various negative health outcomes. While it is often debated whether obesity should be classified as a disease or a risk factor, its impact on health is undeniable.
In medicine, Obesity is defined as a body mass index (BMI) of 30 or higher. BMI is a measure of body fat based on height and weight. A BMI of 25 to 29.9 is considered overweight, and a BMI of 30 or higher is considered obese.

Why Is Obesity a Disease
Obesity is considered a disease by many medical organisations, including the World Health Organization (WHO) and the American Medical Association (AMA). This is because obesity meets the criteria for a disease as defined by these organisations.
A disease is defined as a condition that affects the body’s normal functioning and can lead to adverse health outcomes. Obesity does this in a number of ways. First, it can cause changes in the body’s metabolism, which can lead to insulin resistance and type 2 diabetes. Second, it can put strain on the body’s organs and tissues, which can lead to heart disease, stroke, and other chronic health conditions. Third, it can increase the risk of certain types of cancer.
Is Obesity Considered a Chronic Disease?
Yes, obesity is classified as a chronic disease. Science defines chronic diseases as long-term conditions that require ongoing management and treatment, and obesity aligns with this definition. It triggers various physiological changes in the body, including hormonal imbalances, inflammation, and metabolic dysregulation. These changes contribute to the development of chronic ailments such as heart disease, diabetes, and even in some cases, certain types of cancer. Given its chronic nature and far-reaching implications, obesity demands continuous attention and management.
Obesity is not simply a result of poor lifestyle choices or lack of willpower. It involves complex interactions between genetic, environmental, and behavioural factors that make it difficult to overcome without proper management and treatment.
Moreover, the impact of obesity extends beyond physical health. It can significantly affect an individual’s mental and emotional well-being, leading to low self-esteem, depression, and social isolation. These psychological consequences further emphasise the chronic nature of obesity as they often persist even after weight loss.
How Does Obesity Affect Your Body?
Obesity can have a profound impact on the body, leading to a range of health issues including heart problems, diabetes, joint complications, and more. Factors contributing to obesity include poor dietary choices, lack of physical activity, genetic predisposition, and hormonal influences.

Early and Distant Complications Resulting from Obesity
Obesity gives rise to a spectrum of early and distant complications across multiple bodily systems. These include disruptions to the endocrine and reproductive systems, heightened cardiovascular risks, compromised respiratory function, increased vulnerability of the excretory system, and added stress on the locomotor system. These complications underscore the urgency of addressing obesity as a significant public health concern.
Endocrine and Reproductive Systems
Obesity’s impact on the endocrine and reproductive systems is far-reaching and complex. The accumulation of excess fat can disrupt hormonal balance, leading to insulin resistance—a hallmark of type 2 diabetes. This metabolic turmoil not only heightens the risk of diabetes but also contributes to other hormonal imbalances that affect overall health. In the realm of reproduction, obesity can introduce challenges for both men and women. In women, irregular menstrual cycles and ovulatory dysfunction can impede fertility, making conception more difficult. For men, obesity can lead to reduced testosterone levels and impaired sperm quality. Understanding the intricate interplay between obesity and these systems is essential for comprehensive health management.
Obesity in Pregnancy
Pregnancy is a transformative period during which obesity can exacerbate health risks for both the expectant mother and her developing baby. Obese pregnant individuals are at an elevated risk of developing gestational diabetes—a condition that can lead to complications for both mother and child. Preeclampsia, a potentially life-threatening condition characterised by high blood pressure and organ damage, is also more prevalent in obese pregnancies. Caesarean deliveries are often necessitated by obesity-related factors such as difficulties in labour progression. Furthermore, infants born to obese mothers may face an increased likelihood of birth defects and developmental challenges. Effective prenatal care and management strategies are vital to mitigate these risks and ensure the well-being of both mother and child.
Obesity places an undeniable burden on the cardiovascular system, leading to an array of detrimental effects. The excessive weight strains the heart, making it work harder to pump blood throughout the body. This strain contributes to the development of hypertension (high blood pressure), a condition that can damage blood vessels and increase the risk of heart disease and stroke. Additionally, the presence of excess fat can lead to the accumulation of plaque in arteries—a condition known as atherosclerosis—further exacerbating cardiovascular risks. Prioritising interventions such as adopting a heart-healthy diet, engaging in regular physical activity, and managing weight can play a pivotal role in preserving cardiovascular well-being.
The respiratory system’s functioning can be compromised by obesity, impacting both the mechanics of breathing and overall lung capacity. Excessive body weight can impede the expansion of the lungs, leading to reduced oxygen intake and efficiency. These disruptions are particularly evident during sleep, where obesity increases the risk of obstructive sleep apnea. This condition involves repeated interruptions in breathing during sleep, leading to fragmented sleep patterns and increased daytime fatigue. The interplay between obesity and respiratory function underscores the importance of weight management and interventions to improve breathing quality and overall lung health.
The excretory system, responsible for filtering waste and maintaining fluid balance, faces distinct challenges in the presence of obesity. The excess weight places strain on the kidneys, potentially leading to kidney disease and kidney stones. The kidneys play a crucial role in regulating blood pressure and filtering toxins from the bloodstream. Obesity’s impact on kidney function can contribute to a range of complications, including reduced filtration capacity and an increased risk of chronic kidney disease. Maintaining a healthy weight and adopting lifestyle changes that support kidney health are essential for preventing these complications.
The locomotor system, encompassing bones, joints, and muscles, bears the brunt of obesity-related stress. The added weight places heightened pressure on weight-bearing joints such as the knees, hips, and lower back. Over time, this pressure can accelerate wear and tear, leading to conditions like osteoarthritis—a degenerative joint disease characterised by pain, stiffness, and reduced mobility. Obesity-related inflammation further compounds joint discomfort and deterioration. Engaging in regular physical activity, managing weight, and adopting joint-friendly practices are pivotal in preserving the integrity of the locomotor system and enhancing overall quality of life.
- Steps for Losing Weight?
Losing weight involves a combination of healthy lifestyle changes. Start by setting realistic goals, creating a balanced diet with portion control, and incorporating regular physical activity. Stay hydrated, manage stress, and prioritise sufficient sleep. Tracking your progress and seeking professional guidance can also be beneficial.
- Causes and Effects of Obesity?
Obesity arises from factors such as poor dietary habits, lack of physical activity, genetic predisposition, and hormonal influences. Its effects encompass a range of health complications, including heart disease, diabetes, joint issues, and respiratory problems. Understanding these causes and effects is essential for effective prevention and management.
- Who Classifies Obesity as a Disease?
Obesity is classified as a disease by reputable medical organisations such as the World Health Organization (WHO) and the American Medical Association (AMA). Their definitions emphasise its deviation from normal bodily functioning and the resulting negative health outcomes.
- Why is Obesity Considered a Disease?
Obesity meets the criteria for disease classification due to its disruption of normal bodily functions, impairing homeostasis, and leading to adverse health consequences. This categorization highlights the need for comprehensive attention, treatment, and management to mitigate its impact on individual and public health.
