Obesity

Obesity is a complex medical illness involving excess body fat. It’s not just a cosmetic problem. It’s a medical problem that increases the risk of developing many other sicknesses and health problems, including heart disease, diabetes, hypertension, high cholesterol, liver disease, obstructive sleep apnea, and some types of cancer.

• There are many reasons why some people struggle to lose weight. Obesity is often due to hereditary, physiological, and conservational factors, combined with diet, physical activity, and exercise.
• The good news is that even a small amount of weight loss can progress or prevent health problems related with obesity. Eating healthier, being more active, and making lifestyle changes can help you lose weight. Other options for treating obesity include prescription weight-loss medications and procedures.

Symptoms

Many health care professionals also measure your waist circumference to help make treatment decisions. This measurement is called your waist circumference. Health problems associated with excess weight are more common in men with a waist circumference greater than 102 cm (40 inches). They are more common in women with a waist circumference greater than 89 cm (35 inches). Your body fat percentage is another measurement that can be used in a weight loss program to track your progress.

When to See a Doctor

If you’re concerned about your weight or health problems related to being overweight, talk to your doctor about obesity treatment. Together, you can assess your health risks and discuss weight-loss options.

Causes

• While genetic, behavioral, metabolic, and hormonal factors influence body weight, obesity happens when more calories are consumed than burned through daily activities and exercise. The body stores these excess calories as fat.
• In the United States, most people consume too many calories, often from fast food and high-calorie beverages. Obese people may consume more calories than they feel full, feel hungry more quickly, or eat more due to stress or anxiety.
• Many people in Western countries now have much less demanding jobs, so they tend not to burn many calories at work. Even everyday activities require fewer calories, thanks to expediencies such as remote controls, escalators, online shopping, drive-thru restaurants, and banks.

Risk Factors

• Obesity is often the result of a grouping of causes and contributing factors:
• Family History and Factors Affecting It
• Genes inherited from parents can influence the amount of fat stored and its distribution. Genetics can also influence how efficiently food is converted into energy, appetite regulation, and calorie burning during exercise.
• Obesity tends to run in families. And it’s not just about shared genes. Family members also often have similar eating habits and physical activity patterns.

Lifestyle

• Unhealthy Diet. A high-calorie diet, low in fruits and vegetables, and high in fast food, high-calorie beverages, and excessive portion sizes, contributes to weight gain.
• Liquid Calories. Many calories can be consumed without feeling full, especially those from alcohol. Other high-calorie beverages, such as sugary sodas, can contribute to weight gain.
• Lack of Physical Activity. If you lead a sedentary life, you can easily consume more calories per day than you burn through exercise and everyday activities. Using a computer, tablet, or phone is also inactive. The number of hours spent in front of a screen is powerfully associated with weight gain.

Certain Medical Conditions and Medications

• In some people, obesity can be caused by medical conditions, such as hypothyroidism, Cushing’s syndrome, Prader-Willi syndrome, and others. Medical problems, such as arthritis, can also cause reduced activity, which can lead to weight gain.
• Certain medications can cause weight gain if not compensated for through diet or physical activity. These medications include steroids, some antidepressants, anticonvulsants, diabetes medications, antipsychotics, and some beta-blockers.

Socioeconomic Issues

• Socioeconomic factors are associated with obesity. It is difficult to avoid obesity if you don’t have safe places to go or exercise. You may not have learned how to cook healthy meals or lack access to healthier foods. Additionally, the persons you spend time with can inspiration your weight. You’re more likely to grow obesity if you have obese friends or family members. Age
• Obesity can happen at any age, even in young children. However, as you age, hormonal variations and a less active lifestyle increase your risk. The amount of body muscle also tends to decrease with age. Decreased muscle mass often leads to a slower metabolism. These changes also reduce your need for calories and can make it difficult to maintain excess weight. Unless you consciously monitor your diet and become more physically active as you age, you’re likely to gain weight.

Other factors

• Pregnancy. Weight gain during pregnancy is common. Some women have difficulty losing weight after having a baby. This weight gain can contribute to female obesity.
• Quitting smoking. Quitting smoking is frequently associated with weight gain. And, in some people, it can lead to weight gain that is considered obesity. This often occurs when people use food as an aid to cope with the process of quitting smoking. But, in general, quitting smoking still has more health benefits than continuing to smoke. Your healthcare professional can help you prevent weight gain after quitting smoking.
• Lack of sleep. Not getting enough sleep can reason hormonal changes that increase appetite. The same goes for sleeping too much. You may also experience cravings for high-calorie and high-carbohydrate foods, which can donate to weight gain.
• Stress. Many external factors that affect mood and well-being can contribute to obesity. When people are stressed, they often crave high-calorie foods.
• Microbiome.The composition of gut bacteria depends on what you eat and can donate to weight gain or problems losing weight. Even if you have one or more of these risk factors, it doesn’t mean you’re destined for obesity. You can counteract most risk factors through diet, physical activity, and exercise. Behavioral changes, medications, and obesity treatments can also help.

Complications

Obese people are more likely to develop several potentially serious health problems, such as:

• Heart disease and stroke. Obesity increases the likelihood of developing high blood pressure and unhealthy cholesterol levels, which are risk factors for heart disease and stroke.
• Type 2 diabetes. Obesity can affect how the body uses insulin to control blood sugar. This growths the risk of developing insulin resistance and diabetes.
• Certain types of cancer. Obesity can increase the risk of cancer of the uterus, cervix, endometrium, ovaries, breast, colon, rectum, esophagus, liver, gallbladder, pancreas, kidney, and prostate.
• Digestive problems. Obesity increases the likelihood of developing heartburn, gallbladder disease, and liver disease.
• Sleep apnea. Obese people are more likely to suffer from sleep apnea, a potentially serious condition in which breathing repeatedly stops and starts during sleep.
• Osteoarthritis. Obesity increases stress on weight-bearing joints. It also contributes to inflammation, which includes swelling, pain, and a feeling of heat in the body. These factors can lead to complications such as osteoarthritis.
• Fatty liver disease. Obesity increases the risk of developing fatty liver disease, a condition that occurs when excess fat builds up in the liver. In some cases, it can lead to severe liver damage, known as cirrhosis.
• Severe COVID-19 symptoms. Obesity increases the risk of developing severe symptoms if infected with the virus that causes coronavirus disease 2019, known as COVID-19. People with severe COVID-19 may require treatment in intensive care units or even mechanical ventilation.

Conclusion

Obesity is a multifaceted and multifactorial disease that poses serious risks to individual well-being and public health. It is not only the result of poor lifestyle habits but also a combination of genetic, environmental, psychological, and socioeconomic factors. Without proper care, obesity increases therisk of developing chronic diseases such as type 2 diabetes, cardiovascular disease, some cancers, and joint problems. Addressing obesity requires a inclusive approach that includes education, behavioral change, creating an enabling environment, medical interventions, and public health policies. Encouraging a balanced diet, regular physical activity, mental health support, and equal access to health care are critical for prevention and long-term treatment. Through coordinated efforts at the individual, societal, and political levels, obesity rates can be reduced and the quality of life of millions of people worldwide improved.
