Stretch marks (striae or stria gravidarum) are the curse of pregnant women, when they develop on their belly and breasts, and overweight people whose stretch marks persist after they have lost weight. The tendency to develop striae is one that may be inherited.
They are caused by a break down and stretching of the elastic fibres in the skin by changes in the body’s hormone levels as well as direct stretching of the skin. Once they form they usually remain permanently unless removed by plastic surgery or reduced by creams containing retinoic acids.
Cushing syndrome is caused by an over production of steroids such as cortisone in the body, or taking large doses of cortisone. Headache, obesity, thirst, easy bruising, impotence, menstrual period irregularities, stretch marks, acne, high blood pressure, bone pain and muscle weakness are common symptoms of this syndrome.
