Obesity is a medical condition characterized by excessive accumulation of body fat to a degree that adversely affects health. It is typically determined by measuring body mass index (BMI), which is a ratio of an individual’s weight to height. A BMI of 30 or higher is generally considered to indicate obesity. Obesity is a major public health concern globally, as it is associated with a wide range of health problems, including type 2 diabetes, heart disease, stroke, high blood pressure, certain cancers, sleep apnoea, osteoarthritis, and mental health issues such as depression and anxiety. Here is everything that you should know about obesity:

Types of Obesity
There are two main types of obesity:
- Android or abdominal obesity – This type of obesity is characterized by excess fat accumulation around the waist and upper body, giving an apple-shaped appearance. This type of obesity is more common in men than women and is associated with a higher risk of cardiovascular disease, type 2 diabetes, and other health problems.
- Gynoid or hip/thigh obesity – This type of obesity is characterized by excess fat accumulation around the hips and thighs, giving a pear-shaped appearance. This type of obesity is more common in women than men and is generally considered to be less harmful to health than abdominal obesity.
It’s important to note that these two types of obesity are not mutually exclusive, and many people may have a combination of both types. In addition to these two types, there are also other classifications of obesity, such as metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO), which are based on the presence or absence of metabolic abnormalities, such as high blood pressure, high blood sugar, and high cholesterol levels.
Here are some facts about obesity:
- According to the World Health Organization, obesity has more than tripled worldwide since 1975.
- In 2016, over 1.9 billion adults were overweight, and over 650 million of them were obese.
- In the United States, more than one-third of adults are obese.
- Obesity is a leading cause of preventable death worldwide.
- Obesity is associated with an increased risk of many chronic health conditions, including heart disease, stroke, type 2 diabetes, certain cancers, and osteoarthritis.
- Obesity is also associated with a higher risk of mental health issues, such as depression and anxiety.
- The economic costs of obesity are substantial, including increased healthcare costs, lost productivity, and decreased quality of life.
- Obesity can be prevented and treated through lifestyle changes, such as eating a healthy diet and engaging in regular physical activity.
- Bariatric surgery, such as gastric bypass surgery, can be an effective treatment for severe obesity.
- Obesity is a complex condition with multiple contributing factors, including genetics, environmental factors, and individual behaviour.
Obesity Causes/Causes of Obesity
Obesity is a complex condition with multiple contributing factors. Here are some common causes of obesity:
- Genetics – Some people may be predisposed to obesity due to genetic factors that affect metabolism and fat storage.
- Environment – Environmental factors, such as easy access to high-calorie foods and sedentary lifestyles, can contribute to obesity.
- Diet – A diet high in calories, saturated fat, sugar, and processed foods can contribute to weight gain and obesity.
- Lack of physical activity – Sedentary lifestyles, such as spending long hours sitting or engaging in minimal physical activity, can contribute to obesity.
- Hormonal imbalances – Certain hormonal imbalances, such as insulin resistance and hypothyroidism, can contribute to obesity.
- Medications – Some medications, such as certain antidepressants and antipsychotics, can cause weight gain and contribute to obesity.
- Age – As people age, their metabolism slows down, which can lead to weight gain and obesity.
- Sleep – Poor sleep habits, such as not getting enough sleep or poor-quality sleep, can contribute to obesity.
It’s important to note that obesity is often caused by a combination of these factors and can vary from person to person. In order to effectively address and prevent obesity, it’s important to take a comprehensive approach that considers all of these potential causes.
Obesity is a medical condition that is determined by measuring body mass index (BMI), which is a ratio of an individual’s weight to height. However, here are some physical symptoms of obesity:
- Excess body fat – People who are obese generally have a high amount of body fat, particularly around the waist and upper body.
- Difficulty with physical activity – Obesity can make physical activity, such as walking or climbing stairs, more difficult.
- Breathlessness – Obesity can make it harder to breathe, particularly during physical activity.
- Excessive sweating – People who are obese may sweat more than usual, particularly in areas such as the armpits and groin.
- Joint pain – Obesity can put extra strain on the joints, particularly the knees and hips, leading to joint pain and stiffness.
- Skin irritation – People who are obese may experience skin irritation and infections, particularly in areas where skin rubs together, such as the thighs and underarms.
- Sleep apnoea – Obesity can contribute to sleep apnoea, a condition in which a person’s breathing is interrupted during sleep, leading to snoring and poor sleep quality.
It’s important to note that not all people who are obese will experience these symptoms, and some people may experience symptoms not listed here. Additionally, the severity of these symptoms may vary depending on the degree of obesity. If you are concerned about your weight or are experiencing any of these symptoms, it’s important to talk to a healthcare professional.
The treatment for obesity typically involves a comprehensive approach that includes lifestyle changes, behavioural therapy, medication, and in severe cases, bariatric surgery. Here are some common treatments for obesity:
- Lifestyle changes – This includes adopting a healthy diet that is rich in fruits, vegetables, lean proteins, and whole grains, and limiting high-calorie and high-fat foods. Increasing physical activity levels and engaging in regular workout can also help to promote weight loss.
- Behavioural therapy – This involves working with a therapist or counsellor to identify and address unhealthy behaviours that may be contributing to obesity. This may include stress management, emotional eating, and establishing healthy habits.
- Medications – There are several medications available that can help to promote weight loss by reducing appetite or blocking the absorption of fat. These medications are typically used in combination with lifestyle changes and under the guidance of a healthcare professional.
- Bariatric surgery – In severe cases of obesity, bariatric surgery may be recommended. This involves surgical procedures that reduce the size of the stomach, limiting the amount of food that can be eaten.
It’s important to note that the best approach to treating obesity will vary depending on the individual and the severity of their condition. A healthcare professional can help to develop a comprehensive treatment plan that is tailored to each individual’s needs and goals. Additionally, prevention is key, and maintaining a healthy weight through a balanced diet and regular exercise is the best way to prevent obesity-related health problems.
Obesity Prevention/How to Prevent Obesity
Preventing obesity requires a combination of healthy lifestyle choices and environmental factors. Here are some ways to prevent obesity:
- Maintain a healthy diet – A healthy diet that is rich in fruits, vegetables, lean proteins, and whole grains can help to prevent obesity. Limiting high-calorie and high-fat foods, such as fast food and sugary drinks, can also help.
- Engage in regular physical activity – Regular exercise can help to prevent obesity by burning calories and promoting overall health. Aim for at least 30 minutes of moderate intensity exercise most days of the week.
- Limit sedentary behaviour – Sedentary behaviours, such as sitting for long periods of time, can contribute to obesity. Take breaks throughout the day to stand and stretch and try to incorporate more physical activity into your daily routine.
- Get enough sleep – Poor sleep habits, such as not getting sound sleep or poor-quality sleep, can contribute to obesity. Aim for 7-9 hours of sleep per night.
- Manage stress – Stress can contribute to unhealthy behaviours, such as emotional eating, which can lead to weight gain and obesity. Practice stress-management techniques, such as meditation or deep breathing, to help manage stress.
- Create a supportive environment – Create an environment that supports healthy behaviours, such as having healthy food options available and encouraging physical activity.
- Seek support – Seek support from family, friends, or a healthcare professional to help you maintain healthy habits and prevent obesity.
It’s important to note that preventing obesity requires a long-term commitment to healthy behaviours and environmental factors. Small changes over time can make a big difference in preventing obesity and promoting overall health.
Obesity is a serious medical condition that can lead to a range of health problems. It’s caused by a combination of genetic, environmental, and lifestyle factors. The best way to prevent obesity is through healthy lifestyle choices, such as maintaining a healthy diet, engaging in regular physical activity, and managing stress. If you’re concerned about your weight, talk to a healthcare professional to develop a comprehensive plan that’s tailored to your needs and goals.
