Overweight and obesity are among the most common health concerns in modern society, and many people fail to keep their weight under control. Obesity is connected with accumulation of fat in the body, that leads to increases of the body mass. Obesity is a result of spending less calories than it was received with the food consumed, and keeping positive energy balance in the body. In a great number of cases obesity is considered to be a serious health condition, which requires medical treatment directed on lowering the body mass.
Specialists define certain stages of obesity. There are the early stages, when the body mass is about 30-50% greater than the ideal weight, and the latest stages of obesity, when the body mass is more than 80-100% greater than the ideal weight. It is possible to estimate how much overweight or obese a person is by using so called Body Mass Index (BMI).
On the earliest stages of obesity (BMI is 25-35) a person usually does not feel much of physical discomfort and does not tend to connect possible ailments and diseases with extra weight. However, it is very important to realize possible dangers and risks, connected with weight gain, and start changing the life-style by doing regular exercises, using more of physical activities and eating a healthy diet.
The following progressive stages of obesity (BMI is 35-40) can be characterized by certain problems with movements and mobility, possible pains in joints and muscles, breathlessness, increased heart rate, extra pressure on spine, sleep apnea and other health problems. On these stages, if no positive changes are made to the life-style and daily diet, the risks of having very serious health problems in the future increase greatly.
Finally, on the latest stages of obesity (severe obesity, BMI is over 45) a person starts feeling strong psychological pressure and serious physiological changes, like changes of the body proportions, limited mobility, increased levels of blood sugar an cholesterol, and so on. A person on the latest stages of obesity requires immediate medical attention and using any type of effective treatment directed on weight reduction. Otherwise, the consequences can turn into life-threatening health conditions.
