Obesity is a complex medical condition characterized by excessive body fat accumulation. It has become a global health concern, affecting millions of individuals across diverse demographics. In this article, we will delve into the symptoms, causes, risk factors, diagnosis, treatment, prevention, related conditions, and the challenges faced by individuals living with obesity. By examining various perspectives, we can gain a comprehensive understanding of this prevalent health issue.


According to the World Health Organization (WHO), worldwide obesity has nearly tripled since 1975. In 2016, more than 1.9 billion adults were overweight, while over 650 million were classified as obese (1). In the United States, obesity rates have skyrocketed over the past few decades, with more than one-third of adults and nearly one-fifth of children and adolescents being obese (2).


The most apparent symptom of obesity is excessive weight gain and an increased body mass index (BMI). However, there are several accompanying signs and symptoms that individuals may experience, including but not limited to:

  1. Breathlessness
  2. Joint pain
  3. Fatigue
  4. Lack of physical endurance
  5. Difficulty sleeping
  6. Excessive sweating
  7. Low self-esteem and depression

Causes and Risk Factors

Obesity is a multifactorial condition influenced by a combination of genetic, environmental, and lifestyle factors. The primary causes and risk factors include:

  1. Poor diet: Consuming calorie-dense, nutrient-poor foods, known as a Western diet, is a leading contributor to obesity.
  2. Sedentary lifestyle: Inadequate physical activity is strongly associated with weight gain.
  3. Genetics and family history: Genetic factors can predispose individuals to obesity (4).
  4. Socio-economic factors: Limited access to healthy food and opportunities for physical activity can contribute to obesity.
  5. Psychological factors: Emotional eating, stress, and certain mental health conditions can lead to unhealthy weight gain.


Diagnosing obesity involves assessing an individual’s BMI, waist circumference, and overall health. Generally, a BMI greater than or equal to 30 is indicative of obesity. Additional diagnostic tests may be conducted to evaluate the presence of related health conditions such as high blood pressure, diabetes, or heart disease.


The treatment of obesity aims to achieve and maintain a healthy weight to reduce associated health risks. An effective treatment plan typically includes a combination of the following:

  1. Lifestyle Changes: Adopting a healthy, balanced diet and engaging in regular physical activity are essential components in managing weight.
  2. Medications: In certain cases, medications may be prescribed to assist in weight loss by suppressing appetite or reducing fat absorption.
  3. Surgery: Bariatric surgery or weight loss surgery is considered for individuals with severe obesity that has not responded to lifestyle changes or medications.
  4. Devices: Various devices, such as gastric balloons or electrical stimulation systems, may assist in weight loss efforts for specific individuals.Treatment


Preventing obesity is crucial to combat its rising prevalence. It involves several key measures, including:

  1. Promoting healthy diets: Encouraging the consumption of nutrient-rich, whole foods while limiting the intake of processed foods and sugary beverages.
  2. Encouraging regular physical activity: Advocating for increased physical activity in individuals of all ages, be it through sports, recreational activities, or active transportation.
  3. Public health initiatives: Implementing policies and programs that promote healthy eating environments in schools, workplaces, and communities.

Related Conditions

Obesity increases the risk of developing various related health conditions, including:

  1. Type 2 diabetes
  2. Cardiovascular diseases
  3. Hypertension (high blood pressure)
  4. Sleep apnea
  5. Certain types of cancer

Living with Obesity

Living with obesity can present numerous challenges, both physically and emotionally. Individuals may face social stigma, discrimination, and reduced quality of life. It is important to foster a supportive and inclusive environment to help individuals maintain motivation and improve their overall well-being.
