2022年4月21日 · Gigantism and acromegaly are primarily caused by excess growth hormone. Most commonly, these conditions are caused by a benign, or noncancerous, tumor in the pituitary gland.

2023年3月20日 · Gigantism occurs when growth hormone hypersecretion occurs before the fusion of the long bone epiphysis and is characterized by tall stature. Acromegaly occurs when GH hypersecretion occurs after the fusion of the epiphysis leading to large extremities and characteristic facies.

2022年5月9日 · Gigantism, also called pediatric acromegaly and pituitary gigantism, is a very rare condition that happens when a child or adolescent has high levels of growth hormone (GH) in their body, which causes them to grow very tall.

2024年1月18日 · Excess growth hormone causes both gigantism and acromegaly. The main difference between the two is that gigantism occurs in children before puberty, and acromegaly happens after puberty...

Gigantism and acromegaly are syndromes of excessive secretion of growth hormone (hypersomatotropism) that are nearly always due to a pituitary adenoma. Before closure of the epiphyses, the result is gigantism. Later, the result is acromegaly, which causes distinctive facial and other features.

2024年2月6日 · Acromegaly is a hormonal disorder that develops when your pituitary gland produces too much growth hormone during adulthood. When you have too much growth hormone, your bones increase in size. In childhood, this leads to increased height and is called gigantism. But in adulthood, a change in height doesn't occur.

2023年3月20日 · Gigantism occurs when growth hormone hypersecretion occurs before the fusion of the long bone epiphysis and is characterized by tall stature. Acromegaly occurs when GH hypersecretion occurs after the fusion of the epiphysis leading to large extremities and characteristic facies.

2019年6月24日 · Acromegaly is oversecretion of growth hormone which begins in adulthood. Gigantism is oversecretion of growth hormone which begins in childhood. What is Acromegaly? Acromegaly is the oversecretion of growth hormone from the pituitary gland starting at some time between the ages of 20 and 40 years.

Learn about the key differences between acromegaly and gigantism. 1. Onset. Gigantism begins in childhood, whereas acromegaly starts between ages 20-40. 2. Causes. A pituitary tumor is the primary cause of both acromegaly and gigantism. However, other genetic conditions can also cause gigantism, including:

Overproduction of growth hormone causes excessive growth. In children, the condition is called gigantism. In adults, it is called acromegaly. Excessive growth hormone is almost always caused by a noncancerous (benign) pituitary tumor. Children develop great stature, and adults develop deformed bones but do not grow taller.
