Obesity

Defined obesity as the accumulation of abnormal or excessive fat, which may cause a danger to health, and can be classified as whether a person is obese, or not, by using the body mass index ( in English: Body mass index): an indicator to measure body weight In kilograms to square height in meters, a person is considered obese if the BMI is equal to 30, or more, while if the index is equal to 25 or more, this is classified as an increase in weight , and obesity and weight gain are among the risk factors causing many diseases Chronic. [1]

Causes of obesity

There are many factors that cause obesity and weight gain , the most important of which are the following: [2] [3]
  • Heredity: Obesity is related to hereditary factors , where the child is more likely to develop obesity if his parents have it, but that depends on other factors, such as the nature of food, where it was found that obesity rates in non-industrial cities have increased after the start of the Western diet, despite Although the genes do not change, however, it is the environmental factors that have changed, and on the other hand, studies have indicated that genes have an effect on susceptibility to weight gain.
  • Processed foods: Processed foods contain refined ingredients, and additives. These foods are made with a focus on making them delicious, inexpensive, and with a long shelf life to attract the consumer, and this leads to excessive intake of Food, on the other hand, the manufacturers of these foods may use various methods to increase sales.
  • Food addiction: Many high-fat processed foods and sugars stimulate the reward centers in the brain. These foods can cause addiction in people who are susceptible to this, as the person loses control of his nutritional behavior.
  • Insulin: The hormone insulin plays an important role in regulating energy stores in the body, as it urges the fat cells in the body to store fat and preserve the fat in it in advance. It is worth noting that following a Western diet may increase insulin resistance in the English language. the body in people with obesity , which leads to energy storage in fat cells rather than provided for use in the body, many studies have indicated that the high proportion of insulin may be reasons that lead to obesity, and on the other hand, it can Low levels of insulin by refraining from eating simple sugars and refined carbohydrates, and increased intake of dietary fiber.
  • Certain medications: Many types of drugs cause weight gain, including antidepressants (antidepressant), diabetes and antipsychotics, as these drugs alter the functions of the body and brain by increasing appetite. Or reduce the metabolism rate.
  • Leptin resistance: The hormone leptin is produced by fat cells, and its levels in the blood increase with increasing fat mass in the body. Therefore, the levels of leptin are high in obese people, and it can be said that the height of leptin in healthy people is related to a decrease in appetite , but it does not work the same way when People with obesity, where he cannot exceed the blood-brain barrier in English, and this condition is called Leptin Resistance, which is one of the factors that cause obesity.
  • Sugar: The use of sugar can be one of the worst aspects of the modern diet , as its excess consumption leads to a change in hormones and biochemistry in the body, as its consumption is linked to weight gain, and added sugar consists of glucose and fructose, and glucose can be obtained from other food sources Like starches, however, most of the consumed quantities of fructose are from sugar. Increasing fructose intake can lead to insulin resistance and increased levels in the body, and it does not enhance the feeling of satiety, such as glucose. Because of these factors, Added sugar may contribute to increased energy storage, leading to obesity.
  • Lack of physical activity: Most people currently follow the sedentary lifestyle because of the use of devices and modern means of transportation, and lack of movement may lead to reducing the amount of calories that the body burns, as studies have indicated that the activity Physical exercise has a positive effect on regulating insulin levels, as instability of its levels may be linked to weight gain.
  • Lack of sleep: One study indicated that people who do not sleep long enough are twice as likely to be obese as sleep deprivation stimulates ghrelin secretion, which increases appetite. On the other hand, lack of sleep leads to poor sleep. Producing less quantities of the leptin hormone, which reduces appetite.

Complications of obesity

Obesity is associated with many health complications that can be dangerous to human life, and these complications include the following: [4]
  • Type 2 diabetes.
  • Heart diseases.
  • High blood pressure .
  • Gallbladder diseases.
  • High cholesterol .
  • Infertility (English: Infertility).
  • Arthritis (English: Arthritis).
  • Stroke (in English: Stroke).
  • Fatty liver disease (English: Fatty liver disease).
  • Sleep apnea, and other respiratory problems.
  • Some types of cancer, such as breast cancer, colon , and endometrial cancer (English: Endometrial).
