A chronic, relapsing, multi-factorial, neurobehavioral disease, when there is an increase in body fat regulates the dysfunction of adipose tissue and abnormal fat, that results in adverse effects on the health which includes metabolic, biomechanical, and psychosocial consequences, the above mentioned is the obesity medical definition.
In 1998, the National Institutes of Health declared obesity a disease. In simple words, the meaning of obesity is as follows: “Overweight”. Let us learn what causes obesity, what are the medical complications and how to prevent it?
Short Note on Obesity
Obesity is identified when the body mass index (BMI) is equal to 30 or greater than that. The body mass index can be calculated easily by dividing the body weight by squaring the height. But the BMI alone cannot estimate body fat but it is considered as one of the factors.
Obesity meaning is as follows, it is a complex disease involving an excessive amount of body fat. Obesity isn’t just a cosmetic concern. It is a medical problem that will increase the risk of getting affected with other diseases such as heart attack, diabetes, and certain cancers. Usually, obesity is caused by a combination of inherited factors, that are combined with the environment and exercise choices and personal diet.
Causes
Although there are genetic, behavioral, metabolic, and hormonal influences on weight, obesity occurs once you absorb more calories than you burn through exercise and normal daily activities. Your body stores these excess calories as fat. People might eat more calories before feeling full, feel hungry sooner, or eat more during stress or anxiety.
Risk Factors
1. Family Inheritance and Influences: The genes that we get from our parents may affect the amount of fat stored in our body, and where that fat is distributed. Obesity tends to run in families which is not just because of the genes they share but because of similar eating and activity habits.
2. Food Habits: A diet that’s high in calories, lacking in fruits and vegetables, filled with nutrients, and laden with high-calorie beverages and oversized portions contributes to weight gain. Liquid calories such as alcohol, soft drinks, high-calorie beverages etc. If a person has a sedentary lifestyle, he can easily take in more calories every day than he burns through exercise and routine daily activities. Looking at a computer, tablet, and phone screen may be a sedentary activity. The number of hours a person spends in front of a screen is highly associated with weight gain.
3. Age: Obesity can occur at any age, even in young children and as a person ages, hormonal changes and a less active lifestyle increases the risk of obesity. In addition, the quantity of muscle in your body tends to decrease with age. The lower muscle mass can result in a decrease in metabolism. These changes also reduce calorie needs and may make it harder to stay off excess weight.
4. Diseases: Many health conditions can lead to weight, and in turn obesity. And obesity can further aggravate the conditions, creating a vicious cycle of weight gain. Diseases such as hypothyroidism, insulin resistance, polycystic ovary syndrome, and Cushing’s syndrome are known to be contributors to obesity.
4. Other Factors:
-
Quitting Smoking: When people quit smoking, they will consume more food to fulfill the cravings that in turn results in weight gain. At the end of the day, however, quitting smoking remains a greater benefit to your health than is constant smoke. Your doctor can assist you to prevent weight gain after quitting smoking.
-
Negative Emotions: Things like boredom, sadness, or anger, can have a huge influence on eating habits, leading to the intake of high calories.
Complications

-
Heart Disease and Strokes: Obesity causes you to be more likely to possess high vital signs and abnormal cholesterol levels (high LDL cholesterol, low HDL cholesterol, or high levels of triglycerides), which are risk factors for heart condition and strokes.
-
Type 2 Diabetes: Our body uses insulin to regulate blood glucose levels which can affect obesity. It raises the risk of resistance to insulin and diabetes.
-
Digestive Problems: Obesity increases the likelihood that you’re going to develop heartburn, gallbladder disease and liver problems.

Gynecological and Sexual Problems: Obesity can also cause infertility and irregular periods in women. Obesity also can cause erectile dysfunction in men.

The arteries, in turn, resist this flow of blood, causing the rise in blood pressure or hypertension. Obesity and hypertension combined are a leading cause of cardiovascular disease.
-
Sleep Apnea and Breathing Problems: Fat deposits in the upper respiratory tract narrow the airway, resulting in a decrease in muscle activity in this region. This could lead to hypoxic and apneic episodes, resulting in sleep apnea.
-
Mental Illness: It could also contribute to mental illnesses such as clinical depression, anxiety, and other mental disorders.
-
Gallbladder Disease: In obesity, the hypersecretion of cholesterol causes local secretion of fat, leading to gallbladder disease.
-
Severe COVID-19 Symptoms: Obesity increases the danger of developing severe symptoms if you become infected with the virus that causes coronavirus disease 2019 (COVID-19). People who have severe cases of COVID-19 may require treatment in medical care units or maybe mechanical assistance to breathe.
