Obesity: Causes, Consequences, & Management

Did you know that the World Health Organization (WHO) defines obesity as the abnormal or excessive accumulation of fat that can pose a threat to our well-being? 

To measure obesity, experts commonly use a calculation called body mass index (BMI). This involves dividing a person’s weight in kilograms by the square of their height in meters. If an adult has a BMI of 30 or higher, they are classified as obese.

On the other hand, if their BMI is 25 or higher, they are considered overweight. For children aged 5-19, being overweight is determined by having a BMI for age that is more than 1 standard deviation above the WHO Growth Reference median, and obesity is identified as being more than 2 standard deviations above the WHO Growth Reference median.

It’s important to keep an eye on our BMI to ensure we maintain a healthy weight and reduce the risk of associated health problems.

Global prevalence and increase in obesity rates 

Obesity poses a major global health challenge that cannot be ignored. The World Obesity Federation reports that the number of obese individuals worldwide has nearly tripled from 1975 to 2016, reaching a staggering 2 billion adults who are currently grappling with excess weight.

Among them, a staggering 650 million individuals are classified as obese. Unfortunately, the situation is projected to worsen by 2025, with an estimated 167 million people, both adults and children, succumbing to the detrimental effects of being overweight or obese.

This alarming trend is not limited to any specific age group. Both adults and children have experienced a surge in obesity rates, particularly in urban areas and low- to middle-income countries. The prevalence of overweight or obese children under the age of 5 has seen a significant rise, painting a concerning picture for the future.

Moreover, obesity rates have shown disparities across different regions. Wealthier countries in Europe, North America, and Oceania have higher rates, while South Asia and Sub-Saharan Africa have comparatively lower rates.

The escalating rates of obesity are not to be taken lightly, as they have far-reaching consequences for public health. We must address this pressing issue and work towards promoting healthier lifestyles and combating the global obesity epidemic.

The Causes of Obesity

Obesity is a complex problem that can be influenced by various factors. One of the key contributors is eating patterns, particularly the consumption of processed or fast food, alcohol, sugary drinks, and larger portions than necessary. These unhealthy eating habits can contribute to weight gain and obesity.

Another factor is the level of physical activity. A lack of exercise and spending excessive time in front of screens, such as tablets and phones, can lead to weight gain. It is important to maintain an active lifestyle to prevent obesity.

Sleep routines also play a role in weight management. Insufficient sleep and poor sleep quality can influence excess weight gain. It is crucial to prioritize a healthy sleep routine to support a healthy weight.

Genetics can also contribute to obesity. Genetic changes in human populations can increase the risk of obesity, and certain gene variants may lead to increased hunger and food intake.

Social determinants of health can also influence obesity. Factors such as the affordability of healthy food options, peer and social support, marketing and promotion, and community design policies can all impact obesity rates.

Certain illnesses and medications can also contribute to weight gain. Conditions like Cushing’s disease, hypothyroidism, and Prader-Willi syndrome can lead to obesity. Additionally, certain medications, including steroids and some antidepressants, may cause weight gain.

Lastly, stress, emotional factors, and poor sleep can contribute to overeating and weight gain. Some individuals may turn to food as a coping mechanism when they are bored, angry, upset, or stressed. Furthermore, inadequate sleep can disrupt hormonal balance and increase the likelihood of being overweight or obese.

The Consequences of Obesity

Obesity carries a multitude of consequences, resulting in a heightened vulnerability to severe illnesses and health conditions. As stated by the CDC, individuals grappling with obesity face an elevated risk of developing ailments such as hypertension, elevated cholesterol levels, type 2 diabetes, heart disease, stroke, respiratory issues, joint complications, and certain forms of cancer.

Moreover, obesity is intertwined with psychological challenges, diminished self-confidence, societal discrimination, and a reduced quality of life.

The World Health Organization (WHO) also emphasizes the grave health repercussions of obesity, encompassing cardiovascular ailments, type 2 diabetes, musculoskeletal disorders, and select cancers, which can ultimately lead to untimely demise and significant disability.

Furthermore, obesity is associated with an augmented likelihood of disability and mortality, along with escalated healthcare expenses. The health impacts of obesity extend far and wide, affecting both physical and mental well-being, while also imposing a substantial economic burden on healthcare systems.

Management and Treatment for Obesity

Management and treatment options for obesity typically encompass a combination of various approaches. These include making lifestyle changes, utilizing medications, and, in certain cases, considering weight-loss surgery.

The U.S. Food and Drug Administration (FDA) has approved several medications for obesity treatment, with bupropion being one of the most commonly used ones. However, it is important to note that these medications should be used in conjunction with dietary modifications, exercise, and behavior changes, rather than being relied upon as standalone solutions.

When it comes to lifestyle changes for addressing obesity, several strategies can be implemented:

• Dietary changes: Reducing calorie intake is a crucial aspect of weight loss. For women, a typical range is 1,200 to 1,500 calories, while for men, it is 1,500 to 1,800 calories.

• Feeling satisfied with less: Cutting back on certain foods, such as desserts, can contribute to weight loss efforts.

• Support groups: Joining support groups offered by local hospitals or commercial weight-loss programs can provide valuable motivation and guidance throughout the journey.

• Utilizing smartphone apps and other tools: These technological aids can assist in tracking progress and ensuring adherence to the weight-loss plan.

• Behavior change: Shifting the focus towards unhealthy dietary habits and incorporating physical activity into daily life can greatly aid in achieving weight loss goals.

• Therapy: In cases where obesity is accompanied by eating disorders, therapy can be instrumental in bringing about behavioral and attitudinal changes.

Weight-loss surgery also referred to as metabolic and bariatric surgery, may be suggested in certain situations when an individual has a body mass index (BMI) of 35 or above. This surgical procedure brings about weight reduction by altering the digestive system.

Collaborating with a healthcare expert is crucial to creating a customized treatment plan, taking into account various factors like age, overall health, physical capabilities, medical background, previous weight-loss attempts, tolerance for specific treatments, and desired outcomes for the condition’s progression.

Conclusion 

In conclusion, obesity is a multifaceted issue that is impacted by a range of genetic, environmental, and lifestyle factors. It is essential to comprehend the causes and effects of this condition to effectively manage and treat it.

By intervening early and taking preventive measures, you can significantly decrease the likelihood of experiencing health complications associated with obesity.
