The disease may be inherited or caused by problems with how the body uses insulin, obesity, some drugs, and cancer. |

acromegaly |
|
- Acromegaly is excessive growth. It is caused by the oversecretion of growth hormone. The condition results in the gradual enlargement of the bones in the face, jaw, hands, feet, and skull. |

ACTH stimulation test |
|
- This test checks how the adrenal glands respond to a certain hormone. The hormone is called adrenocorticotrophic hormone, or ACTH. ACTH is made in the pituitary gland and travels through the bloodstream to the adrenal glands. ACTH stimulates the adrenal gland to release cortisol. Cortisol is important for many functions in the body's metabolism of fats, carbohydrates, sodium, potassium, and protein. |

ACTH test |
|

|
|
metyrapone test |
|
- The metyrapone test evaluates how the adrenal glands respond to adrenocorticotrophic hormone, or ACTH. ACTH is made in the pituitary gland and travels through the bloodstream to the adrenal glands. There it triggers the release of another hormone called cortisol. |
