Lesser-known causes of obesity, according to the MSD Manual, and how to treat it with a bariatric surgeon
Obesity is a disease that develops over time for various reasons. These can be genetic, dietary, or as a consequence of illnesses; however, there are different methods to treat it alongside a bariatric surgeon—a specialist in obesity—using surgeries adapted to the patient's condition, achieving their ideal weight.
Aimed at raising awareness about this disease, World Obesity Day is commemorated every March 4th to inform about its causes and treatments.
Obesity can be defined as an increase in the patient's body fat levels, generated by consuming more calories than the body burns during exercise and normal daily activities.
In Mexico, 70% of people over the age of 20 suffer from this condition. Although it is very common to associate it with poor eating habits or lack of exercise, other factors can cause it in the population.
Causes of obesity you might not know
In addition to the patient's lifestyle, it has been discovered that genetic inheritance and the behavior of the nervous, endocrine, and metabolic systems, among other factors, contribute to this condition.
According to information published by the MSD Manual, these are the causes that can generate this condition in individuals:
Genetics Family genes can influence various aspects of obesity, such as how quickly the body burns calories (whether at rest or during exercise), the feeling of appetite, the amount of food the person consumes, and the area of the body where body fat accumulates. This can occur due to gene mutation, as there are cases where this effect prevents the satiety signal from reaching the hypothalamus, causing the person to continue eating without limits and becoming more prone to developing excess weight.
Menopause Hormonal changes cause a redistribution of fat and its accumulation around the waist in women; it is said they can experience an increase in body mass of approximately 17%. Menopause symptoms can also lead to a decrease in women's daily activities. Considering this inactivity factor, if adequate care and attention are not received for the weight gain, obesity could develop.
Aging Muscles are structures responsible for burning a large number of calories, and as a person ages, their body composition changes, causing muscle tissue to decrease and preventing the elimination of unnecessary calories. Furthermore, fatigue, age, and the wear and tear of muscles and bones can cause a lack of mobility, which also impacts fat elimination, leading to excess weight.
There are also more common causes, such as people's eating habits, contributed to by the frequent excess consumption of high-calorie foods, as well as physical inactivity or sedentary lifestyles becoming more frequent; activities with minimal physical effort do not allow burning the daily necessary calories.
These are just a few reasons why a person might have obesity, but regardless of which it is, it is important to remember that solutions for treating this condition do exist. One of them is the procedures of a bariatric surgeon.
A bariatric surgeon can prevent the effects of obesity
This condition has increasingly appeared in the Mexican population; it is said that nine out of 10 Mexicans will have some degree of overweight by 2050. Situations like quarantine have normalized sedentary routines and the frequent consumption of fast-food delivery.
The effects of obesity involve weight gain, mobility complications, lack of energy, and the generation of other disorders such as diabetes, hypertension, cancer, and respiratory problems, among others, as well as emotional effects, as it can cause self-esteem issues, anxiety, and depression in the patient.
Fortunately, the care provided by a bariatric surgeon can help people with obesity not only achieve their ideal weight but also prevent the aforementioned conditions and improve their quality of life.
A bariatric surgeon is a specialist in performing surgical procedures like the gastric sleeve or gastric bypass, recognized for helping thousands of people with obesity.
These bariatric surgeries are performed when the patient has not been able to lose weight with diets, exercise, or faces other causes like genetics, body changes, or illnesses. The bariatric surgeon offers these operations as an alternative to help people reach their ideal weight goal quickly, effectively, and, above all, safely.
To perform these treatment methods, the bariatric surgeon first analyzes the patient's situation and health status to identify the one that best suits their needs, as with the right treatment, the bariatric surgeon can prevent or even control the aforementioned disorders.
Dr. Luis Zavala, a bariatric surgeon, is a specialist who works alongside the patient to accompany them in their life change and achievement of their ideal weight goal, answering questions, scheduling appointments, and providing other bariatric consulting services.
Undoubtedly, this bariatric surgeon can become an ally to maintain good health in overweight patients, thanks to his solutions and techniques that involve a comprehensive methodology, integrating a team of specialists who provide the patient with various forms of care to help them with psychological aspects, disease prevention, dietary care, and metabolism, among others.
Living an unhealthy lifestyle is not easy, but the understanding, care, and treatment that a bariatric surgeon can offer generate new, safe, and effective alternatives to guide the patient in achieving their health goals.
