reduction

The restoration of a displaced or broken part of the body to its proper position or alignment by manipulation or other surgical procedure. Reduction of bone fractures involves energetic pulling (traction) under anaesthesia to correct overlap, and local moulding pressure to realign the bone.

reduction

a change in an atom or molecule through losing oxygen, adding hydrogen, or gaining electrons.

Reduction

The restoration of a body part to its original position after displacement, such as the reduction of a fractured bone by bringing ends or fragments back into original alignment. The useof local or general anesthesia usually accompanies a fracture reduction. If performed by outside manipulation only, the reduction is described as closed; if surgery is necessary, it is described as open.

2. the addition of hydrogen to a substance, or more generally, the gain of electrons; the opposite of oxidation.

Patient discussion about reduction

Q. Does intake of diet rich in fiber will be beneficial for weight reduction? I feel obesity is a hindrance to a happy life and though many weight reduction and slimming techniques are currently available, how can one choose the correct technique. Does intake of diet rich in fiber will be beneficial for weight reduction?

A. Yes, researches indicate that the normal weight adults tend to eat more fiber and fruit than people who are overweight or obese. The difference found was that the normal-weight adults consume about 33 % more dietary fiber and 43 % more complex carbohydrates each day than people who are obese. Thus it is shown that consumption of a balanced diet that includes an adequate amount of fiber from plant foods will surely benefit your health and weight. You must have fiber rich foods if you are obese.
