Not every pound above normal weight makes you sick. But overweight, if it persists for a long time, is still a trailblazer for many diseases. Often, the first symptoms are shortness of breath when climbing stairs, sleep apnea (more than ten seconds of persistent respiratory arrest during sleep), increased tendency to sweat, joint and joint pain. Much more dangerous, however, are accompanying and sequelae, which develop gradually over years or decades. Today many chronic diseases and disorders caused by obesity or aggravated.
Insulin resistance and metabolic syndrome
Insulin resistance is when there is an increased insulin level while the body is less responsive to the effects of insulin. The most common cause of this is overeating with readily available carbohydrates. The pancreas is producing more and more insulin, so that finally the blood sugar level drops. Nevertheless, this remains too high due to resistance to insulin. The results are diabetes mellitus type 2 and an exhausted pancreas.
Secondary and concomitant diseases
According to Professor Arnold Astrup from Copenhagen (9th European Congress on Obesity, ECO, June 1999, Milan), obesity is more than three times more likely to cause cancer than normal weight:
- Diabetes mellitus type 2
- Gallbladder disease
- high blood pressure
- Difficulty breathing, sleep apnea
Two to three times more frequently than normal weight occur:
- coronary heart disease
- Osteoarthritis or gout
The following diseases can occur up to 2 times more frequently:
- certain cancers (uterine, breast, cervix, prostate and gallbladder carcinoma)
- sex hormone disorders
- back pain
Obesity additionally increases the risk of thrombosis and embolism and, last but not least, increases the risk of surgery and anesthesia. Obesity leads to psychosocial problems and quality of life limitations. Those affected often suffer from depression, reduced self-esteem, and lesser environmental recognition.
Every kilo less increases life expectancy!
Being overweight is not only a serious threat to your health, but can also shorten your life span, in addition to the various health restrictions. The mortality risk is 1.3 times higher than that of normal weight even with moderately increased BMI (= 27). At a BMI of 35, it even increases to 2.5 times.
However, this risk can be counteracted by losing weight. For example, a 12-year study of 15, 069 overweight 40- to 64-year-old women shows that weight reduction lowers the mortality rate by as much as 20 percent. Every kilo less increases the life expectancy.
