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.
Addisonâs disease can present as an acute illness or come on gradually. A rare complication of Addisonâs disease is adrenal crisis, which presents as shock, or very low blood pressure. The risk increases if you are have an infection or a major physical stress. With chronic Addisonâs, the symptoms are vague and non-specific, and Addison's disease can be difficult to diagnose. Often, it's first detected through routine blood tests in a hospital or doctor's office to check for sodium, potassium and white blood cell levels.
