Obesity is a medical condition in which excess body fat gets accumulated to the extent that it may, lead
to reduced life expectancy and/or increased health
problems. People are considered obese when their body mass (BMI), a measurement obtained by dividing a
person's weight by the square of the person's height, exceeds 30 kg/m2, with the range 25-30 kg/m2 defined as overweight.
Obesity increases the likelihood of various diseases, particularly heart disease, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis. Obesity is most
commonly caused by a combination of excessive food energy intake, lack of physical activity, and genetic susceptibility, although a few cases are caused primarily by
genes, endocrine disorders, medications, or psychiatric problems. Evidence to
support the view that some obese people eat little yet gain weight due to a
slow metabolism is limited. On average, obese people have greater energy
expenditure than their thin counterparts due to the energy required to maintain
an increased body mass.
Dieting and exercising are the main treatments for obesity. Diet quality can be improved
by reducing the consumption of energy-dense foods, such as those high in fat and
sugars, and by increasing the intake of dietary fiber. With a suitable diet,
anti-obesity medicines may be taken to reduce
appetite or decrease fat absorption. If diet, exercise, and medication are not
effective, a gastric balloon may assist with weight loss.
Obesity is a leading preventable cause of death worldwide, with increasing rates in adults and
children. Authorities view it as one of the most serious public health problems of the 21st century. Obesity is stigmatized in much of the modern world, though
it was widely seen as a symbol of wealth and fertility at other times in
history and still is in some parts of the world.
If you have osteoarthritis in your hip, losing even a few pounds can help offset pressure on the joint and relieve hip pain. So, a necessary diet control can add the goodies in your health bag.
While we know that weight gain has a negative impact on joint
health and function, we also know the reverse to be true – in general,
weight-loss can have a very positive impact on joint health. A 2005 study that
followed around 150 overweight and obese patients with OA found that a
weight-loss of 5 percent brought about an average 18 percent improvement in OA
symptoms, including reduced pain and improved joint function. With RA,
maintaining a lower weight is linked to better outcomes and recovery. A study
that looked at the response of RA patients to a common treatment, found that
compared to those of normal weight, only about half of the overweight and obese
patients went into a state of remission.
Overall, body weight is
significantly connected to the health of your joints. One benefit of
maintaining lower weight is clearly a reduced risk for all forms of joint
disease. If you are overweight and suffer from arthritis, even small amounts of
weight-loss may significantly improve the health and function of your joints.
