Detailed explanation-1: -Growth hormone deficiency (GHD), also known as dwarfism or pituitary dwarfism, is a condition caused by insufficient amounts of growth hormone in the body. Children with GHD have abnormally short stature with normal body proportions. GHD can be present at birth (congenital) or develop later (acquired).

Detailed explanation-2: -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. Instead, the increase in bone size is limited to the bones of your hands, feet and face, and is called acromegaly.

Detailed explanation-3: -Overproduction of growth hormone causes excessive growth. In children, the condition is called gigantism. In adults, it is called acromegaly.

Detailed explanation-4: -Acromegaly happens because your pituitary gland (a pea-sized gland just below the brain) produces too much growth hormone. This is usually caused by a non-cancerous tumour in the pituitary gland called an adenoma.
