Understanding Acth Hormone

The anterior pituitary gland produces the essential peptide hormone known as adrenocorticotropic hormone or ACTH. Its main function is to control the amount of cortisol released in reaction to stress. An essential component of the body’s stress response mechanism, ACTH aids in preserving regular physiological cycles. Because imbalances in ACTH can result in a number of health problems, clinical diagnosis and research have placed a great deal of emphasis on them.

One of the two lobes that comprise your pituitary gland, a tiny endocrine gland situated near the base of your brain, is your anterior pituitary. More than six distinct hormones that impact numerous body functions are produced and released by the anterior pituitary.

Well, in this article, I’ll be discussing Acth Hormones, their definition, function, location, Conditions, and Disorders, and how to take care of them.


What is Acth Hormone?

A hormone called adrenocorticotropic hormone (ACTH) is generated by the brain’s anterior pituitary gland. This hormone plays a role in controlling the amounts of cortisol that the adrenal gland releases as well as the steroid hormone. Other names for ACTH include corticotropin, arginine vasopressin, serum adrenocorticotropic hormone, and adrenocorticotrophin.

The most important hormone needed for the adrenal glands to operate is termed adrenocorticotropic hormone, which causes the cortex to produce the stress hormone cortisol. ACTH also follows a diurnal (daily) rhythm, with higher levels in the morning and lower levels in the evening, which is important for maintaining the body’s circadian rhythm. Imbalances in ACTH production or cortisol levels can lead to various medical conditions.

For example, excessive ACTH production can result in Cushing’s syndrome, characterized by the overproduction of cortisol, while insufficient ACTH can lead to adrenal insufficiency, resulting in insufficient cortisol production. Proper regulation of ACTH is essential for maintaining the body’s homeostasis and managing the stress response.

Function of Adrenocorticotropic hormone

What hormones are secreted by the anterior pituitary?

Six primary hormones are produced and secreted by your anterior pituitary:

  • Adrenocorticotropic hormone (ACTH, or corticotropin): This hormone stimulates your adrenal glands (the glands on top of your kidneys) to produce cortisol and other hormones.
  • Follicle-stimulating hormone (FSH): This hormone stimulates the testes to produce sperm and stimulates the ovaries to produce eggs and estrogen.
  • Luteinizing hormone (LH): This hormone stimulates ovulation in women and testosterone production in men.
  • Growth hormone (GH): In children, growth hormone stimulates growth. In adults, growth hormone helps maintain healthy muscles and bones and impacts fat distribution.
  • Prolactin: This hormone stimulates breast milk production after giving birth and can affect menstrual periods, fertility and sexual function (by causing low testosterone in people assigned male at birth and low estrogen in people assigned female at birth).
  • Thyroid-stimulating hormone (TSH): This hormone stimulates your thyroid to produce hormones that manage metabolism, energy, and your nervous system.


Where is the anterior pituitary located?

The pituitary gland is situated behind the hypothalamus, behind the nasal bridge, and near the base of the brain. It is located in the sella turcica, a little pouch or chamber in the sphenoid bone.

There is a contact between the two lobes that make up your pituitary gland. The pituitary gland’s posterior lobe is located in the rear of your head and faces the back, whereas the anterior pituitary is located in the front and faces the front of your head.

How big is the anterior pituitary?

Your pituitary gland is roughly the size of a pea, with a total diameter of only about 1/3 of an inch. About 80% of your pituitary gland’s overall weight is made up of the anterior pituitary, which is larger than the posterior pituitary.

What is the anterior pituitary made of?

Six hormones are produced by cell clusters in the anterior pituitary and released into the bloodstream. Hormones produced and released by various cell cluster types include:

  • Adrenocorticotrophic hormone (ACTH) is produced by corticotrophs.
  • Thyroid-stimulating hormone is produced by thyrotrophs (TSH).
  • Growth hormone (GH) is produced by somatotrophs.
  • Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are produced by gonadotrophs.
  • Prolactin (PRL) is produced by lactotrophs.

Conditions and Disorders

What conditions are related to the anterior pituitary?

The regulation of ACTH production in the body is the primary cause of problems involving ACTH. The amount of ACTH produced by them could either rise or fall. A person may develop specific problems depending on their age and changes in lifestyle.

The anterior pituitary produces a wide range of hormones, which makes it a target for a number of various disorders. In general, hypopituitarism (underactive pituitary gland) or hyperpituitarism (overactive pituitary gland) are the causes of the majority of disorders involving the anterior pituitary. Your anterior pituitary either produces too little or too much of one or more hormones in these situations.

The following circumstances or conditions are typically responsible for hypopituitarism and hyperpituitarism:

  • malignancies of the pituitary gland (adenomas).
  • harm from trauma, infection, or blood loss to your anterior pituitary, hypothalamus, or pituitary stalk.
  • hereditary diseases like multiple endocrine neoplasia (MEN).

Hyperpituitarism conditions

Higher-than-normal amounts of one or more anterior pituitary hormones might cause the following conditions:

  • Acromegaly: An extremely uncommon disorder known as acromegaly arises from an overproduction of growth hormone (GH) by a benign (noncancerous) tumor in the anterior pituitary. Your body’s tissues and bones are impacted, leading to aberrant growth. Adults who suffer from acromegaly often experience hand, foot, lip, and jaw enlargement.
  • Cushing’s disease: An excess of cortisol produced by the adrenal glands results in Cushing’s syndrome. Cushing’s disease, a subtype of Cushing’s syndrome, is characterized by an excess of cortisol produced by the adrenal glands as a result of an anterior pituitary malfunction. A benign tumor in your anterior pituitary gland produces excess adrenocorticotrophic hormone (ACTH), which leads your adrenal glands to produce excessive amounts of cortisol, which is the cause of Cushing’s disease. Along with other symptoms, it can cause fast weight gain, primarily in the face, abdomen, and back of the neck.
  • Hyperthyroidism: An overactive thyroid gland that secretes excessive amounts of its own hormones is known as hyperthyroidism. This condition is typically brought on by the anterior pituitary releasing excessive amounts of thyroid-stimulating hormone (TSH), which is typically the result of a benign pituitary tumor. This hyperthyroidism cause is quite uncommon.

Hypopituitarism conditions

Conditions that are the result of lower-than-normal levels of one or more anterior pituitary hormones include:

  • Secondary adrenal insufficiency: Adrenocorticotrophic hormone (ACTH) typically tells your adrenal glands to produce the necessary hormone cortisol. Your adrenal glands will be underactive if your pituitary gland releases insufficient amounts of ACTH. This is referred to as central or secondary adrenal insufficiency (not to be confused with the main adrenal gland illness-related cortisol shortage known as Addison’s disease).
  • Deficiency in growth hormone: This disorder is brought on by lower-than-normal growth hormone (GH) releases from your anterior pituitary. Adults with GH deficiencies may have changes in their body composition, including abnormally high cholesterol, alterations in fat and muscle, and decreased energy. If children with GH deficiencies have stunted growth and low height.
  • Low sex hormone production, or hypogonadism: This condition can impair your fertility and sex drive. It is caused by the sex glands not producing enough sex hormones. Low levels of luteinizing hormone (LH) and/or follicle-stimulating hormone (FSH) released by your anterior pituitary can result in low levels of estrogen and testosterone.
  • Hypothyroidism: This condition is characterized by an underactive thyroid gland that secretes insufficient amounts of its own hormones. It can be brought on by an anterior pituitary that releases insufficient amounts of thyroid-stimulating hormone (TSH).


Taking care of ACTH hormone levels primarily involves maintaining a healthy lifestyle and addressing any underlying medical conditions that may affect the hormone’s regulation. Here are some general guidelines for supporting ACTH hormone health:

  • Stress Management: High levels of chronic stress can disrupt the hypothalamus-pituitary-adrenal (HPA) axis, which regulates ACTH secretion. Employ stress-reduction techniques such as meditation, deep breathing exercises, yoga, or mindfulness to help manage stress.
  • Balanced Diet: A well-balanced diet is essential for overall hormonal health. Ensure you get an adequate intake of essential nutrients, including vitamins and minerals. In particular, vitamin C, B vitamins, and zinc play a role in the functioning of the HPA axis.
  • Regular Exercise: Engaging in regular physical activity can help regulate hormone levels, including ACTH. However, excessive exercise or overtraining can have the opposite effect, so it’s essential to strike a balance.
  • Adequate Sleep: Quality sleep is vital for hormonal regulation. Aim for 7-9 hours of restful sleep each night to support the natural diurnal rhythm of hormone production.
  • Healthy Lifestyle: Avoid excessive alcohol consumption and smoking, as these habits can disrupt hormonal balance.
  • Manage Medical Conditions: If you have a medical condition that affects the HPA axis or adrenal glands, such as Cushing’s syndrome or Addison’s disease, work closely with your healthcare provider to manage and treat these conditions effectively.
  • Medication and Treatment: If you are on medication that affects the HPA axis, follow your doctor’s instructions diligently. Changes in medication or dosage should only be made under medical supervision.
  • Regular Check-ups: If you suspect any issues with your hormone levels, consult a healthcare provider. They can perform tests to measure ACTH and cortisol levels, and other related hormones if necessary, to diagnose and treat any hormonal imbalances.
  • Weight Management: Maintaining a healthy body weight is important, as obesity can sometimes lead to hormone imbalances.
  • Lifestyle Changes: If you have a high-stress job or lifestyle, consider implementing relaxation techniques, regular breaks, and activities that reduce stress.

Keep in mind that the body’s feedback systems strictly control the amount of ACTH. Medical interventions may be required in certain circumstances if there are medical issues impacting cortisol or ACTH levels. If you’re worried about the health of your hormones, always get specific advice from a healthcare practitioner.


In summary, ACTH (adrenocorticotropic hormone) is a key hormone in our stress response system, regulating the production of cortisol. It plays a crucial role in managing our body’s response to stress and maintaining our daily physiological rhythms. Maintaining a healthy lifestyle, managing stress, and seeking medical attention when necessary are essential for supporting ACTH hormone health.
