Is your pituitary gland overactive? (Hyperpituitarism) Let's talk about this simply!

Do you sometimes feel like something is wrong with your body, like your hormones are out of whack? Maybe it's because of a small gland in your brain. When this gland becomes overactive, it can affect many important functions in your body, such as growth, metabolism, and reproduction. Today we're talking about an overactive pituitary gland, or hyperpituitarism.

What is the Pituitary Gland?

Simply put, the pituitary gland is like a master control center that controls the work of our body. It is a pea-sized gland located at the base of our brain. It is the head of our endocrine system. That is why it is sometimes called the "master gland". It controls the functioning of other important glands such as the thyroid gland, adrenal gland, and gonadal glands.

Think about the thermostat in our house. It constantly checks the temperature in the house and sends signals to the heater and cooler to keep it at the same level, right? The pituitary gland also works in the same way. It constantly monitors the functioning of our body and sends signals to the organs and glands about what work to do, when, and how much. These signals are what we call hormones .

The pituitary gland is connected to a part of our brain called the hypothalamus. The brain tells the pituitary gland whether to secrete more or less of a certain hormone.

What are the main hormones produced by the pituitary gland?

The pituitary gland consists of three main parts. Each part produces different hormones. Let's take a look at what they are and what happens to them.

What diseases occur when the pituitary gland overworks?

When the pituitary gland becomes overactive, that is, when it produces too much of a hormone, various medical conditions can occur. The main cause of this is a non-cancerous (benign) tumor that develops in the gland. This is called a pituitary adenoma .

These are some of the main diseases that can occur due to this:

• Cushing's syndrome: If the pituitary gland secretes too much ACTH, the adrenal glands produce too much cortisol, which can disrupt the body's metabolism and immune system.
• Acromegaly: A condition that occurs when the body's levels of growth hormone (GH) become too high. This causes bones and tissues to grow abnormally.
• Hyperthyroidism: If a pituitary tumor produces too much TSH (this is somewhat rare), the thyroid gland becomes overactive. This can cause things like increased metabolism, rapid heartbeat, and anxiety.
• Prolactinoma: A tumor in the pituitary gland that causes excessive secretion of the hormone prolactin. This can affect the reproductive process in both women and men.

What are the symptoms of these conditions?

The symptoms associated with each condition are different. Let's take a look at what these are. See if you have these symptoms too.

Hyperpituitarism in children

This condition is very rare in children. When it occurs, it is usually caused by a small, non-cancerous tumor called a pituitary microadenoma. The most common condition seen in children is a prolactinoma.

• For girls: Delayed puberty and cessation of menstruation (amenorrhea) may occur.
• For boys: As the tumor grows and presses on nerves, it can cause headaches, vision problems, and other problems. It can also cause delayed puberty or growth problems.

What are the reasons for this?

Hyperpituitarism is often caused by a tumor in the pituitary gland. It is not known exactly why these tumors occur.

• Benign tumors: This is the most common cause. Depending on the type of cell the tumor is made of, it starts to secrete too much of one or two hormones.
• Hereditary conditions: Sometimes, these tumors can be caused by hereditary conditions such as Multiple Endocrine Neoplasia type 1 (MEN1) .
• Carcinoma: Very rarely, a cancerous tumor or disease of the hypothalamus can cause this.

How to recognize this condition?

Now, when you go to see a doctor with these symptoms, he or she will take a detailed history and listen to your symptoms. After that, they may order several tests to confirm the diagnosis.

• Blood and urine tests: These tests measure the levels of hormones in your blood or urine. For example, they check levels of prolactin, cortisol, and growth hormone.
• Imaging Scans: If lab tests suggest a tumor, a scan may be done to confirm it. This can show exactly where the tumor is and how big it is.
• MRI (Magnetic Resonance Imaging) Scan: This is the most commonly used method.
• CT (Computed Tomography) Scan: If you have a pacemaker, a CT scan may be performed because an MRI cannot be performed.

How is it treated?

Depending on your condition, one or more treatment methods may be used together.

Medication

In some cases, medications are given to control hormone levels. For example, in the case of a prolactinoma, medications are given to reduce prolactin levels and shrink the tumor. Medications are also sometimes used to shrink large tumors before surgery.

Surgery

In conditions such as acromegaly or Cushing's syndrome, the tumor is removed surgically. The most common surgery is called a transsphenoidal adenomectomy . In this, the surgeon makes a small incision through the nose or upper lip, reaches the pituitary gland, and removes the tumor. Although this is a very delicate operation, the success rate is over 80% when performed by an experienced surgeon.

Radiation therapy

For those who cannot have surgery, or if parts of the tumor remain after surgery, radiation therapy is used. This involves targeting a beam of high-energy radiation at the tumor and destroying the cells.

How is the outlook?

For many people, the outlook for this condition is good. Although it cannot be cured, with proper treatment and management, many people can control their symptoms and live healthy, happy, and productive lives. In some cases, you may need to take medication or be under medical supervision for a long time. The most important thing is to stay in regular contact with your doctor and let him or her know about any changes in your symptoms.
