Shortage - Definitions. 1  In a perfect market (one that matches a simple microeconomic model), an excess of demand will prompt sellers to increase prices until demand at that price matches the available supply, establishing market equilibrium [1] [citation needed].
Addison's disease. Addisonâs disease, also known as primary adrenal insufficiency and hypocortisolism, is a long-term endocrine disorder in which the adrenal glands do not produce enough steroid hormones. Symptoms generally come on slowly and may include abdominal pain, weakness, and weight loss. Darkening of the skin in certain areas may also occur.
The adrenal glands are found above the kidneys, and they consist of two parts called the medulla and cortex. Damage to the cortex of these glands leads to hyposecretion of cortisol which in turn causes Addison's disease. Some symptoms of this medical condition are diarrhea, feeling tired, pale skin and appetite loss.
