Overview Person with acromegaly. Acromegaly is a disorder characterized by an enlarged face and hands. As the face changes shape, the jaw may protrude, the nose may enlarge, and the lips may thicken. Acromegaly is a hormonal disorder that develops when your pituitary gland produces too much growth hormone during adulthood. When this happens, your bones increase in size, including those of your hands, feet and face. Acromegaly usually affects middle-aged adults.

Endocrine Glands Involved in Acromegaly Endocrine Glands Involved in Acromegaly. The pituitary gland is a small gland at the base of the brain that produces several important hormones to control body functions such as growth, development, reproduction, and metabolism.Growth Hormone (GH) is part of a cascade of hormones that is produced by the pituitary gland.rowth hormone-releasing hormone (GHRH) is a hormone produced by the hypothalamus and its function is to stimulate the pituitary gland to produce GH. Somatostatin secreted by the cells of hypothalamus and also by the cells of stomach, intestine, and pancreas helps inhibit GH production.

Acromegaly â Excessive Growth Hormone in Adults Acromegaly is a growth disorder caused by the secretion of excessive amounts of growth hormone (GH) from the pituitary gland.The characteristic features are an ‘overgrowth’ of the body tissues which presents slightly differently in adults and children.ometimes the regulation is disrupted or disease within the pituitary gland leads to excessive secretion of growth hormone. When there is an excess of growth hormone then it causes an ‘overgrowth’ of the body tissues.

gigantism The opposite condition, dwarfism, is caused by underproduction of the same hormone. (Overproduction of growth hormone in adults causes acromegaly .) Gigantism can be corrected only by early diagnosis in childhood and removal by surgery of part of the pituitary gland or by x-ray treatment.n abnormal condition characterized by excessive size and stature. It is caused most frequently by hypersecretion of growth hormone (GH) that occurs before the closure of the bone epiphyses; it occurs to a lesser degree in hypogonadism and in certain genetic disorders.

- Gigantism is a rare condition that causes abnormal growth in children. It occurs when a child’s body produces too much growth hormone. Early diagnosis is important. Prompt treatment can stop or slow the changes that may cause a child to grow larger than normal.

- The root cause of acromegaly is excessive secretion of growth hormone (GH), caused by either a pituitary tumor or a non-pituitary tumor. Too much GH leads to a cascade of events and the symptoms of acromegaly. Main Acromegaly Cause: Pituitary Tumor.

Acromegaly When you have acromegaly, your body makes too much growth hormone. This makes parts of your body -- like your hands, feet, and face -- grow too much. It also affects your heart and bones.

Gigantism Gigantism, excessive growth in stature, well beyond the average for the individual’s heredity and environmental conditions. Tall stature may result from hereditary, dietary, or other factors. Gigantism is caused by disease or disorder in those parts of the endocrine system that regulate growth and development. Androgen deficiency, for example, delays the closure of end plates, or epiphyses, of the long bones, which usually takes place when full growth is achieved.

Acromegaly Definition and History In almost all acromegaly patients, the overproduction of GH is caused by a benign tumor of the pituitary gland, called an adenoma. These tumors produce excess GH and, as they expand, compress surrounding brain tissues, such as the optic nerves.

Acromegaly FAQs Acromegaly is a serious condition that occurs when the body produces too much of the hormones that control growth. This causes abnormal enlargement of bone, cartilage, muscle, organs, and other tissues.

McCune-Albright Syndrome Clinical Presentation GH-producing somatotroph adenomas can occur in McCune-Albright syndrome. In children, GH excess results in a marked increase in linear growth velocity. If it goes untreated, features of acromegaly can develop later in life, including enlargement of the hands and feet and coarsening of the facial features.

Hepatomegaly - definition Hepatomegaly - definition. Hepatomegaly - an enlarged LIVER. Hepatomegaly is a symptom of numerous conditions involving the liver. Its presence or absence has no correlation to the seriousness of the underlying liver disease. Because hepatomegaly is a symptom rather than a condition, it often resolves when the underlying condition comes under control. Chronic liver conditions may result in long-term hepatomegaly.

Gigantism Overview. Gigantism is abnormally large growth due to an excess of growth hormone (GH) during childhood, before the bone growth plates have closed (epiphyseal fusion). It causes excessive growth in height, muscles, and organs, making the child extremely large for age.

Children - Achondroplasia Children - Achondroplasia What is achondroplasia? Achondroplasia is a type of rare genetic bone disorder. Achondroplasia is the most common type of these disorders. It causes the strong, flexible tissue called cartilage to not be made into bone as normal. This causes a series of signs, such as short arms and legs and a large head. This condition used to be called dwarfism.

Gigantism The term is seldom applied to those who are simply tall or above average whose heights appear to be the healthy result of normal genetics and nutrition. Gigantism is usually caused by a tumor on the pituitary gland of the brain. It causes growth of the hands, face, and feet. In some cases the condition can be passed on genetically through a mutated gene. Other names somewhat obsolete for this pathology are hypersoma (Greek: hyper over the normal level; soma body) and somatomegaly (Greek; soma body, genitive somatos of the body; megas, gen.

acromegaly Acromegaly. A rare disease resulting from excessive growth hormone caused by a benign tumor. If such a tumor develops within the first 10 years of life, the result is gigantism (in which growth is accelerated) and not acromegaly. chronic metabolic condition in adults caused by oversecretion of growth hormones by the pituitary gland. It is characterized by gradual, marked soft tissue enlargement and widening and thickening of skeletal bones in the face, jaw, hands, and feet. Hypertrophy of the vocal cords leads to deepening of the voice.
