Causes of Obesity and Overweight

Introduction

According to the World Health Organization, global obesity rates have tripled since 1975, with more than 1.9 billion adults being overweight in 2016. Obesity and being overweight now pose a greater health risk than being underweight in most countries. The obesity prevalence among adults in the UAE from 2007 to 2016 was found to be 29.9%.

What is Obesity and Overweight?

Obesity is characterized by having excess weight or body fat that can have negative effects on health. A doctor can diagnose obesity by calculating an individual's body mass index (BMI), which compares weight to height. A BMI between 25 and 29.9 indicates excess weight, while a BMI of 30 or above is classified as obesity.

Causes of Obesity

1. Lack of Physical Activities:

   • Sedentary lifestyles and a lack of exercise result in fewer calories being burned, leading to weight gain.
   • Daily activities and exercise can help maintain a healthy weight and reduce the risk of chronic diseases.

2. Diet:

   • Consuming more calories than are burned can lead to weight gain and obesity.
   • Simple carbohydrates, such as sugars and soft drinks, are quickly absorbed into the bloodstream and can contribute to weight gain.

3. Genes:

   • Genetic factors can influence an individual's predisposition to obesity.
   • While genetics play a role, diet and lifestyle choices can still have a significant impact on weight.

4. Diseases:

   • Certain medical conditions, such as hyperthyroidism, polycystic ovary syndrome, insulin resistance, and Cushing's syndrome, can contribute to obesity.
   • These conditions affect hormone levels and metabolic processes related to weight regulation.

5. Psychological Factors:

   • Mental health issues, such as depression and emotional eating, can contribute to weight gain and obesity.
   • Emotional eating, triggered by stress or unresolved emotional issues, can lead to dependence on food as a source of comfort.

6. Sleep:

   • Sleep deprivation can cause hormonal imbalances that lead to overeating and obesity.
   • Lack of sleep can also impair metabolism and influence food choices, often resulting in high-calorie food consumption.

Conclusion

Obesity is a global health concern that increases the risk of chronic conditions like heart disease, diabetes, and stroke. While there are various factors that contribute to obesity, many of them can be managed through lifestyle changes. Engaging in regular exercise and maintaining a healthy diet are effective measures to prevent and manage obesity.
