Observable swelling of body tissues due to fluid accumulation that may be demonstrated by applying pressure to the swollen area (such as by depressing the skin with a finger). If the pressing causes an indentation that persists for some time after the release of the pressure, the edema is referred to as pitting edema.
Any form of pressure, such as from the elastic in socks, can induce pitting with this type of edema. Edema can be caused by either systemic diseases (diseases affecting multiple organ systems) or by local conditions involving just the affected extremities. In systemic diseases that cause edema, the fluid accumulation is primarily due to the body’s retention of too much salt (sodium chloride), causing the body to retain water.

1. As an adjective, pertaining to the pituitary gland or its hormonal secretions. 2. As a noun, the pituitary gland itself.
- Pituitary adenoma
A benign tumor of the pituitary, the master gland that controls other glands and influences numerous body functions including growth. Although the tumor itself is not cancerous, it may affect pituitary function, and therefore may need to be removed.
- Pituitary dwarfism
Dwarfism caused by a lack of growth hormone, usually due to malfunction of the pituitary gland. Children with growth hormone deficiency may grow normally for the first two to three years of life but they then fall behind their peers in height. They are normally proportioned. This is a key point. Treatment is with human […]
- Pituitary gigantism
Excessive growth and too much height due to chronic overactivity of the pituitary gland which is located at the base of the brain. (Growth hormone is specifically made by the anterior pituitary gland.) In pituitary gigantism, there is secretion of too much growth hormone before the end of adolescence. People with pituitary gigantism can truly […]
- Pituitary gland
The main endocrine gland. It is a small structure in the head. It is called the master gland because it produces hormones that control other glands and many body functions including growth. The pituitary consists of the anterior and posterior pituitary. The anterior pituitary is the front portion of the pituitary. Hormones secreted by it […]
