A Simple Guide to Pituitary Disorders, Diagnosis, Treatment and Related Conditions

By Kenneth Kee

This book describes Pituitary Disorders, Diagnosis and Treatment and Related Diseases

The pituitary gland is an endocrine gland sited in the brain.

This small gland produces chemicals called hormones.

Hormones are chemical messengers which assist different organs in the body correspond with each other.

The pituitary gland is a part of a chemical messenger system.

The pituitary gland helps to control the body's functions by secreting hormones into the bloodstream.

These hormones are carried in the blood to their target.

Here they normally cause the secretion of a second hormone.

The target can either be specialized endocrine glands or other forms of body tissue such as clusters of cells.

The pituitary gland, sited at the base of the brain and no bigger than the size of a pea, is often termed the “master” gland since it produces the hormones that regulate the functions of the other endocrine glands and organs.

Some of the glands the pituitary gland regulates are the thyroid gland, the ovaries, the testicles (testes) and the adrenal glands.

The pituitary gland is very close to another important part of the brain, termed the hypothalamus.

The pituitary gland has 2 main components:
1. The component of the pituitary gland at the front, called the anterior pituitary.
2. The component of the pituitary gland at the back, called the posterior pituitary.

These 2 components secrete different hormones which are focused at different parts of the body.

There is also a segment between the 2 main components, called the intermediate part, which secretes a single hormone.

The final component of the pituitary gland is the stalk, which attaches the posterior pituitary to the hypothalamus.

The hypothalamus takes information from many sources about the basic functions of the body.

It utilizes the information it takes to help control these functions.

One of the ways the hypothalamus does this requires regulating the pituitary gland.

The hypothalamus does this by sending its own hormones to correspond with the pituitary gland.

The information assessed by the hypothalamus is the level of different hormones in the blood.

The hypothalamus has special cells which obtain information from the body indicating how much of each hormone is evident in the bloodstream.

When these hormones fall below a particular level this activates the hypothalamus to secrete hormones.

These hormones move to the pituitary gland, providing the signal to the pituitary gland to produce one or more of its hormones.

The hormones produced by the pituitary gland are secreted into the bloodstream.

The bloodstream carries the pituitary hormones to other endocrine glands, such as the thyroid gland.

The pituitary gland hormones may then activate their target endocrine glands to secrete their own hormones.

These locally secreted hormones do the actual function of regulating the body.

Benign pituitary tumors are the main source of pituitary disorders.

Other frequent causes of pituitary disorders are:
1. Head injury
2. Bleeding in or near the pituitary gland
3. Some medicines and cancer treatments

The treatment will be dependent upon the cause:
1.Hormone replacement
2.Pituitary surgery

Introduction

I have been writing medical articles for my blog: http://kennethkee.blogspot.com (A Simple Guide to Medical Disorder) for the benefit of my patients since 2007.

My purpose in writing these simple guides was for the health education of my patients.

Health Education was also my dissertation for my Ph.D (Healthcare Administration).

I then wrote an autobiography account of my journey as a medical student to family doctor on my other blog: http://afamilydoctorstale.blogspot.com.

This autobiography account A Family Doctor’s Tale was combined with my early A Simple Guide to Medical Disorders into a new Wordpress Blog A Family Doctor’s Tale on http://kenkee481.wordpress.com.

From which many free articles from the blog was taken and put together into 800 eBooks.

Some people have complained that the simple guides are too simple.

For their information they are made simple in order to educate the patients.

The later books go into more details of medical disorders.

The first chapter is always from my earlier blogs which unfortunately tends to have typos and spelling mistakes.

Since 2013, I have tried to improve my spelling and writing.

As I tried to bring the patient the latest information about a disorder or illness by reading the latest journals both online and offline, I find that I am learning more and improving on my own medical knowledge in diagnosis and treatment for my patients.

My diagnosis and treatment capability has improved tremendously from my continued education.

Just by writing all these simple guides I find that I have learned a lot from your reviews (good or bad), criticism and advice.

I am sorry for the repetitions in these simple guides as the second chapters onwards have new information as compared to my first chapter taken from my blog.

I also find repetition definitely help me and maybe some readers to remember the facts in the books more easily.

I apologize if these repetitions are irritating to some readers.

Pituitary Disorders

What is the pituitary gland?

The pituitary gland is an endocrine gland sited in the brain.

This small gland produces chemicals called hormones.

Hormones are chemical messengers which assist different organs in the body correspond with each other.

The pituitary gland is a part of a chemical messenger system.

The pituitary gland helps to control the body's functions by secreting hormones into the bloodstream.

These hormones are carried in the blood to their target.

Here they normally cause the secretion of a second hormone.

The target can either be specialized endocrine glands or other forms of body tissue such as clusters of cells.

The pituitary gland, sited at the base of the brain and no bigger than the size of a pea, is often termed the master gland since it produces the hormones that regulate the functions of the other endocrine glands and organs.

Some of the glands the pituitary gland regulates are the thyroid gland, the ovaries, the testicles (testes) and the adrenal glands.

About the size of a pea, the pituitary gland is evident at the base of the brain, behind the bridge of the nose.

The pituitary gland is very close to another important part of the brain, termed the hypothalamus.

The pituitary gland has 2 main components:

1. The component of the pituitary gland at the front, called the anterior pituitary.

2. The component of the pituitary gland at the back, called the posterior pituitary.

These 2 components secrete different hormones which are focused at different parts of the body.

There is also a segment between the 2 main components, called the intermediate part, which secretes a single hormone.

The final component of the pituitary gland is the stalk, which attaches the posterior pituitary to the hypothalamus.

How does the pituitary gland work?

The body is in a constant situation of change.

The heart rate, blood pressure and body temperature all alter in reaction to what the patient does and the surroundings.

The body has systems that regularly review these and other vital functions.

Not only must these systems review changes, they must also react to the alterations and help the body to restore balance.

Some of these systems affect the hypothalamus and the pituitary gland.

The hypothalamus and the pituitary gland are ingredients of several loops or circuits.

The loops involve other glands.

The hormones secreted by each gland complete the loops by moving in the bloodstream between them.

The hypothalamus takes information from many sources about the basic functions of the body.

It utilizes the information it takes to help control these functions.

One of the ways the hypothalamus does this requires regulating the pituitary gland.

The hypothalamus does this by sending its own hormones to correspond with the pituitary gland.

The information assessed by the hypothalamus is the level of different hormones in the blood.

The hypothalamus has special cells which obtain information from the body indicating how much of each hormone is evident in the bloodstream.

When these hormones fall below a particular level this activates the hypothalamus to secrete hormones.

These hormones move to the pituitary gland, providing the signal to the pituitary gland to produce one or more of its hormones.

The hormones produced by the pituitary gland are secreted into the bloodstream.

The bloodstream carries the pituitary hormones to other endocrine glands, such as the thyroid
