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.
Addison's disease can occur at any age and in both sexes. Adrenal insufficiency occurs because the outer layer of the adrenal glands is destroyed. Symptoms of Addison's disease include fatigue, nausea, diarrhea, muscle pain, joint pain, weakness and dizziness. Treatment requires the replacement of the low levels of hormones with medications such as hydrocortisone or prednisone to replace cortisol, and fludrocortisone, if aldosterone levels are low.
