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.
In most cases, Addison's disease occurs when the body's immune system mistakenly attacks the adrenal glands causing slowly progressive damage to the adrenal cortex. Signs & Symptoms The symptoms of Addisonâs disease can vary from one individual to another. Symptoms usually develop slowly over time and are usually vague and common to many conditions (nonspecific). This often leads to delays in the proper diagnosis of Addisonâs disease.
