Statistics on Obesity:Non-Hispanic blacks have the highest age-adjusted rates of obesity (49.5%) compared with Mexican Americans (40.4%), all Hispanics (39.1%) and non-Hispanic whites (34.3%) Among people, those with higher incomes are more likely to be obese than those with lower income.Higher income women are less likely to be obese than low-income women.There is no significant relationship between obesity and education among men. Among women, however, there is a trend—those with college degrees are less likely to be obese compared with less educated women.

How does Leptin cause Obesity?

What does Obesity do to the human body/organs/systems?

What are the major symptoms of Obesity?

Physically, the body expands, gains more weight, produces more fat and ultimately grows of out of its “normal” size proportion. Additionally, obesity can cause changes in a person’s organs and systems leading to serious health issues, such as: high blood pressure (hypertension), high cholesterol levels, (which can lead to increased chances of developing a cardiovascular disease such as, coronary heart disease, or a stroke), and most common, type 2 diabetes. It is estimated that just under half of all cases of diabetes are linked to obesity.

Leptin is a cell-signalling hormone that plays a huge role in regulating a person's appetite, food intake and body weight. Leptin acts on specific receptors in the brain which causes the brain to determine how much fat should be in stored. Obesity occurs when the brain fails to sense the leptin hormone correctly, in turn, causing fat to accumulate and metabolism to slow down.

Some of the consequences of being obese include diabetes, high blood pressure, high cholesterol, sleep apnea, heart disease, heartburn, and hormone imbalances. Obesity also causes day-to-day problems such as: loss of breath, increased sweating, snoring, difficulty sleeping, inability to cope with sudden physical activity, feeling very tired, back and joint pains, low confidence levels and low self-esteem.

What is life like with Obesity?

Living with obesity is a very hard thing. People are made fun of and ultimately never feel confident in themselves. They feel as though they never "look good" in their own skin. Obesity is one of the main causes of depression and suicides for many people.

The protein that is produced is called LEPTIN. The chromosome number Leptin is found on is a gene called OLFM4 on chromosome 13, and one called HOXB5 on chromosome 17.

What are the treatments for Obesity?

Incorporating more natural foods into a persons diet, drinking more water, cutting out junk food and getting into the habit of exercising several times every week, a person can drastically lower their weight and decrease their chances of becoming obese. However, if changes to a persons diet and exercise are not effective their doctor will consider medicines for weight-loss such as Xenical. There is also weight reduction surgery, gastric banding, gastric bypass, and gastric balloon insertion if all else fails. However, these treatments are only for extreme cases.

How is Obesity inherited?

Obesity is a dominant trait. Scientists believe that mutations in about eight genes are known to cause obesity in humans for less than five percent of the obesity epidemic in society. Obesity is primarily inherited from the mother, or the father and predominantly occurs in families that have previous histories of obesity. In contrast, obesity can also be inherited from a faulty diet in which only “junk food” prevails in a household. Obesity is caused from a gene called OLFM4 on chromosome 13, and one called HOXB5 on chromosome 17.
