What are the most common pituitary conditions?Īcromegaly is caused by a hormone-producing tumour in the pituitary gland that produces too high a level of growth hormones. An MRI scan of the pituitary area can provide a clear image of such problems. The adenoma can also cause headaches, an accumulation of fluid in the brain, or leakage of brain fluid via the nose. The ophthalmologist can use a visual field test to determine whether the pituitary tumour is pressing on the optic nerve(s). In some situations it is necessary to test the pituitary function with a special stimulation and inhibition test.Ī denomata in de pituitary gland may cause health problems as they grow in size by exerting increasing pressure on the optic nerve(s) or the nerves that control eye movements. The hormone levels in the blood are checked to determine whether the pituitary gland produces too many or too few hormones. Blood test and pituitary hormone function test (stimulation and inhibition test).What types of examinations are commonly used to establish a pituitary condition? The average general practitioner only encounters one patient with a pituitary condition once every 25 years. There are between 10,000 and 15,000 people in the Netherlands with a pituitary condition. Most pituitary tumours develop slowly (over the years) and they are almost always benign. These conditions are usually caused by a tumour (adenoma) in the pituitary gland. Pituitary disorders can lead to either overproduction or underproduction of certain pituitary hormones. What exactly goes wrong in case of a pituitary condition? Oxytocin affects the release of breast milk (lactation). This hormone controls the amount of water that leaves the body via urination. PRL stimulates the mammary gland s to produce breast milk. GH stimulates the liver to produce substances (such as IGF-1) that affect the growth of bones, muscles, and cartilage.
They also play an important role in regulating the menstrual cycle. These hormones stimulate the reproductive organs to produce sex hormones (oestrogen and testosterone). Follicle-stimulating hormones ( FSH ) and luteinising hormones ( LH ).This hormone regulates the production of cortisol (a hormone produced in the adrenal cortex) by the adrenal glands.
What hormones are produced by the pituitary gland? The pituitary gland mainly produces hormones that regulate the functioning of other hormone glands. It is often called the ‘master gland’ since it plays a central role in the production of various hormones in the body. The pituitary gland is an organ, about 1 cm in size, that is located in a cavity in the base of the skull just behind the nose bridge.
