Liver problems develop when the liver is no longer able to filter out toxins in the body. The development of liver disease is usually a gradual process. In people who smoke and drink alcohol, the breakdown of the liver occurs much faster. Obese people may develop liver problems when they take medication for the many health conditions they develop.

Sleep disorders are particularly common among the obese and may be due to excess body mass constricting the airway. Some examples of common obesity associated sleep disorders are apnea, snoring, and hypoventilation syndrome.

Obese men and women are at greater risk of developing certain cancer than men and women of healthy weight. Being obese at the time of diagnosis increases the likelihood of dying of cancer and of cancer recurrence.

A sixteen-year study of over 900,000 men and women (Calle, E. E., et al) evaluated body weight as a factor in cancer survival. According to the study the overall cancer death rate was 52 percent higher in the heaviest men and 62 percent higher in the heaviest women, than in the participants of healthy weight.

In the study, body weight had a significant impact on death rates for the following specific cancers:

Obese people live shorter lives than their thinner counterparts and carry an increased risk of many medical problems. Diabetes is ten times more prevalent in obese people, and its treatment requires adherence to a strict, healthy diet. People who have diabetes are more prone to weight gain, heart disease, and circulation and vision problems.
