Obesity usually is caused by the underlying pathology of accumulation of excess body fat. It impairs health to a great extent especially by raising the risk of other chronic illnesses such as heart disease and diabetes. Obesity is defined as a Body Mass Index (BMI) exceeding 30 kg/m2.

Obesity is one of the most prevalent disorders of developed countries, and its incidence is increasing rapidly. In England for example obesity rose between 13.2% to 23.6% in men and 16.4% to 23.8% in women between 1993 and 2004. In the United States the numbers rose from 23% in 1990 to 31% in 2000. In both countries present figures are nearly one third of the total population.

Incidence of obesity and type 2 diabetes
As the incidence of obesity rises rapidly, so does that of Type 2 diabetes. In 2000 for example the incidence of diabetes worldwide was 171 million. Studies estimate that these numbers are set to rise to 366 million by 2030 according to the World Health Organization. Type 2 diabetes is on a major rise especially in developing countries along with the developed countries. This is probably because of the switching of the developing country populations to a more affluent lifestyle of poor and unhealthy diet accompanied by lack of physical activity.

Diabetes mellitus and obesity
Diabetes mellitus and obesity have a complex relationship. There is a strong association of type 2 diabetes with obesity. Obesity is one of the major risk factors for type 2 diabetes. Further obesity is a precursor of type 2 diabetes with insulin resistance. Insulin is a hormone produced by the pancreas in the body to regulate and bring down the blood sugar levels. In obese individuals with type 2 diabetes, the amount of insulin produced in the body may be normal but this may not meet the requirements of the body. Thus the blood sugar remains elevated. This is termed insulin resistance. Insulin resistance is the hallmark of type 2 diabetes seen among obese individuals.

Home Remedies for Diabetes
The home remedies for diabetes include the use of apple cider vinegar, bitter gourd, fenugreek, cinnamon, aloe vera, water, mango leaves, alfalfa, jamun, curry leaves, and flaxseed oil in different forms. Exercising, healthy sleep patterns, and maintaining oral health are other good behavioral remedies for getting rid of diabetes in a natural way.
