In 2016, over 340 million children and adolescents aged 5-19 were overweight or obese. In the same year, 39% of adults aged 18 years and over were overweight and 13% were obese. In 2019, statistics showed that 38 million children under the age of 5 were overweight or obese.
The word obesity often causes us to think of physical appearance. It is however more than that. It is health condition that increases the risk of several non-communicable diseases such as high blood pressure, diabetes, cancer, arthritis and poor mental health.
What are the causes of obesity?
Obesity and overweight occurs when there is an energy imbalance between calories consumed and calories expended. This means that one takes in more calories than he/she burns through exercise and normal daily activities. This makes the body store these excess calories as fat.
Several factors can contribute to this condition and they include:
Genetic make-up: A person’sgenes may affect the amount of body fat stored and it’s distribution. It also affects appetite and the body’s metabolic rate through food is converted into energy.
Nutrition: A diet that is high in calories, lacking in fruits and vegetables, full of fast food, and laden with high-calorie beverages and oversized portions contributes to weight gain. Liquid calories from beverages such as alcohol and sugared soft drinks, can contribute to significant weight gain.
Inactivity - A sedentary lifestyle can easily lead one to take in more calories than expended
Pregnancy - Weight gain is common during pregnancy. This weight gain may contribute to the development of obesity in women if managed poorly
Poor sleeping habits – Insufficient or excessive sleep can cause changes in hormones that increase appetite. One may also crave foods high in calories and carbohydrates, which can contribute to weight gain.
Stress - Many external factors that affect mood and well-being may contribute to obesity. People often seek more high-calorie food when experiencing stressful situations.
What are the health complications associated with obesity?
Heart disease and strokes - Obesity increases risk of high blood pressure and abnormal cholesterol levels, which are risk factors for heart disease and strokes.
Type 2 diabetes - Obesity can affect insulin function in the body. Insulin is useful for the metabolism and control of blood sugar. This raises your risk of insulin resistance and diabetes
Digestive problems - Obesity increases the likelihood of heartburn, gallbladder disease and liver problems
Poor mental health- Many people especially in younger age groups battle with self-image and this can cause low self-esteem, which in turn predisposes to poor lifestyle choices, which could contribute to poorly managed weight gain. On the other hand, obesity in itself is a cause of stress for many people and it can lead to depression, anxiety and eating disorders such as anorexia and bulimia among other health problems.
Increased severity of symptoms of infections like COVID-19 - Obesity increases the risk of developing severe symptoms if you become infected
