Health risks of being overweight and obese

Being overweight and obese can increase the risk of a number of health problems and may be associated with a number of emotional and social problems. In this article, we will provide more useful information about the health risks of being overweight and obese.

Obesity is an abnormal or excessive accumulation of fat in adipose tissue that impairs health. In most cases, it is the result of energy consumption exceeding energy expenditure over a period of many years. It is defined in adults as a body mass index (BMI) over 30.
Obesity is no longer a disease that only affects more developed, affluent nations. It is currently a worldwide public health problem, affecting all ages and socioeconomic groups. In 1995, it was estimated that worldwide 200 million adults were obese and 18 million children under the age of 5 were overweight. In 2000, the World Health Organization estimated that 1.2 billion people worldwide were overweight, of which at least 300 million adults were obese: about 130 million in developed countries and 170 million in other countries. Overall, the increase in obesity rates has been strongest among the wealthier populations living in less developed countries, which are thought to be developing.
Being overweight and obese can increase your risk of a number of health problems including the following: All causes of death (death); High blood pressure ( Hypertension ); High LDL cholesterol, low HDL cholesterol or high triglyceride levels ( Dyslipidemia ); Type 2 diabetes ; Coronary heart disease; Stroke; Gallbladder disease; Osteoarthritis (the breakdown of cartilage and bone in joints); Sleep apnea and breathing problems; Low quality of life; Mental illness such as clinical depression, anxiety and other mental disorders; Body pain and difficulty with physical activity; Cancers. ..

Healthcare professionals use a measurement called body mass index (BMI) to find out if a person is overweight. BMI is a calculation that uses your height and weight to estimate how much body fat you have.
BMI = weight in kg / (height in meters) 2
After calculating your BMI, your doctor or nurse will plot the results on a BMI chart. This allows health professionals to compare your growth with other teenagers of the same age and sex to see where you fit in.
Under 18.5 - Underweight 18.5 to 25 - Desired or healthy level 25-30 - Overweight 30-35 - Obese (Type I) 35-40 - Obese (Type II) Over 40 - Fat Diseased or severe obesity (Grade III) BMI varies with age. That's why your doctor should plan and track your BMI over time. There are also different rankings for girls and boys.
When your BMI is compared to benchmarks, your doctor can compare it to teenagers your age and sex. Based on where your BMI number shows up, your doctor will decide if your BMI falls within the underweight, healthy weight, overweight, or obese ranges.
While BMI provides a general measure of obesity using height-adjusted weight, measuring waist circumference or waist-hip ratio can provide additional information about where distribution of body fat. Fat concentrated around the stomach is a higher risk factor for heart disease and type 2 diabetes than fat distributed around the hips. In general, men are more at risk of obesity-related diseases when their waist circumference reaches 94cm. For women, the risk rises to 80cm. The risk of the disease increased significantly with 102cm for men and 88cm for women. For people of Asian descent, the numbers are different: a waist measurement of 80cm in women and 90cm in men puts your health at risk.

In general, obesity is often the result of an individual consuming more energy than they need; This is called positive energy balance. This is common in today's society, where there is an abundance of cheap, high-energy foods, and in which both our work and leisure time becomes increasingly sedentary. While there are some negative effects around specific nutrients or foods, there is no single food or nutrient that causes obesity. Body weight is ultimately determined by a person's energy balance, which is the result of a balance between "energy in" as determined by general diet and physical activity levels. "energy out" substance.
In addition to social influences, such as food availability and sedentary lifestyle, genetics also play a role. For example, there are good correlations between the obesity levels of parents and their children, and between siblings, especially twins. Genetic influences on body size and shape should not be used as an excuse to ignore active dietary and lifestyle advice to help maintain a healthy weight.

Obesity can also make the body's cells resistant to insulin. Insulin is a hormone that carries sugar from your blood to the cells in your body, where it is used for energy. If you are resistant to insulin, the sugar cannot be absorbed by the cells, resulting in high blood sugar.
This increases your risk of type 2 diabetes, a condition where your blood sugar is too high. Type 2 diabetes is linked to a host of other health problems, including heart disease, kidney disease, stroke, amputation, and blindness.
