Level of sensitivity of pain in patients with obesity.

Our aim was to find out the presence of differences in pain sensitivity level depending on body weight. 206 healthy persons at the age of 18 to 84 were the objects of the research with the help of the special instrument which action was based on the principle of dosage pressure by a needle on the forearm skin and by registration of indecis pressure extents when the patients felt no pain, when they felt slight pain and when they felt violent pain. The patients with normal body weight didn't feel pain when the pressure of a needle was 28.53 g; persons with surplus body weight and fatness of the 1 degree-46.5 g and persons with fatness of the 2-3 degrees-61.55 g. Slight pain was registered when the pressure was 40.5 g; 57.6 g and 72.9 g conformably. And the violent pain-76.5 g; 91.3 g and 116.2 g. Thus the patients with fatness have higher pain sensitivity threshold then people of other categories, so they feel less pain. The older a person is the higher pain sensitivity threshold is.
