Obesity

Introduction

Obesity cannot be seen only as increased fat in the body, but rather as a chronic disease associated with many other disorders. It is an important risk factor that is involved in the formation and development of serious physical illness.

Causes of obesity

Obesity results from the interaction of genetic and environmental factors. Of course there are certain periods for the development of obesity very important - especially for women pregnancy period and beyond, including the period of transition, the period of adolescence girls, generally, stress factors and certain periods when reduced physical activity; access to employment, family formation, family or work problems, their sports activities, retirement, etc.

Medication

Some medicines may increase appetite and thus contribute to the development of obesity. They are especially certain antidepressants, antipsychotic medication, tranquillizers, hormone therapy that is adrenal cortex hormones that affect metabolism and progestin that is hormone therapy in women (Gronniger, 2005).

Metabolic effects of Obesity

The energy requirements of the organism determine its weight, gender, level of physical activity. Still, there are a variety of individual, largely genetically encoded factors (but also individual experiences with diet and amount of metabolism) that affects energy balance (German, 2006). This means that obesity may occur even if a person really does not consume more than other people. But less likely to move due to a congenital disposition must pay more attention to your diet.

Imbalance between energy intake and expenditure

The imbalance between energy intake and expenditure in respect of all cases and may be caused by:

Excessive energy intake which mainly increase fat intake; they used to have twice as much energy than carbohydrates and proteins. In developed countries, where we are constantly bombarded by ads for all kinds of food and offering emaciated models, food is really excessive. Thus, it is not surprising that more and takes in (Mayer-Davis, Rifas-Shiman, Zhou and Hu, 2006).

Insufficient energy expenditure is mostly due to a lack of physical activity and sedentary lifestyle. Together with excessive intake of food goes hand in hand unfortunately also a complete lack of movement. The human body is to move very well adjusted and if it is for this purpose hardly used (sedentary life, right away, avoiding to operate any sport) will begin to weaken muscle and adipose tissue grows. A lot of it stems from problems reduced performance and physical fitness, higher fatigue, back pain, poor posture attitudes etc.

Usually it is a combination of both factors.

Risk

Obesity is dangerous diseases mainly because of the complications that accompany it. Very often, cardiovascular disease affects the heart and circulatory system. It is usually high blood pressure, coronary heart disease and atherosclerotic vascular changes, which may lead for example to stroke. Furthermore, obese people meet more often with metabolic diseases, especially Type 2 diabetes and elevated cholesterol levels. High health risk for people with very overweight are also more susceptible to cancer; these are primarily colon cancer, breast, kidney, prostate, lung and other organs.

In addition to this, obesity is a huge burden on bones and joints of the ...
