What is endocrinology?

Endocrinology is the sector of hormone-associated sicknesses. An endocrinologist can diagnose and treat hormone issues and the complications that arise from them.

Hormones modify metabolism, respiration, growth, reproduction, sensory perception, and movement. Hormone imbalances are the underlying reason for a wide range of medical situations.

Endocrinology focuses both on the hormones and the many glands and tissues that produce them.

Humans have over 50 distinctive hormones. They can exist in very small amounts and also have a widespread impact on bodily characteristics and development.

Fast records on endocrinology

Here are some key factors approximately endocrinology. More data is within the primary article.

  • Endocrinology includes a wide range of systems inside the human body.
  • The endocrine tissues consist of the adrenal gland, hypothalamus, ovaries, and testes.
  • There are 3 broad companies of endocrine disorders.
  • Polycystic ovary syndrome is the most not unusual endocrine sickness in women.

What is the endocrine system?

The human endocrine machine is composed of some of the glands, which launch hormones to govern many distinctive functions.

When the hormones go away the glands, they enter the bloodstream and are transported to organs and tissues in every a part of the body.

The adrenal, or suprarenal, glands are positioned on top of the kidneys. They are divided into regions. The right gland is triangular, and the left is crescent-formed.

The adrenal glands secrete:

  • corticosteroids, the steroids worried in stress responses, the immune device, inflammation, and more
  • catecholamines, which include norepinephrine and epinephrine, in reaction to stress
  • aldosterone, which impacts kidney feature
  • androgens, or male sex hormones, which include testosterone.

Both ladies and men have a few androgens, but men have better ranges. Androgens control the improvement of characteristics related to males, like facial hair and a deeper voice.


The hypothalamus is placed simply above the brain stem and under the thalamus.

This gland turns on and controls involuntary body features, including respiration, heart price, appetite, sleep, temperature, and the circadian cycles, or day by day rhythms.

The hypothalamus links the nervous system to the endocrine machine thru the connected pituitary gland.

Ovaries and testicles

The ovaries are located on either side of the uterus in females. They secrete the hormones estrogen and progesterone.

These hormones promote sexual improvement, fertility, and menstruation.

The testicles are placed inside the scrotum, beneath the penis in males. They secrete androgens, particularly testosterone.

Androgens control sexual development, puberty, facial hair, sexual behavior, libido, erectile function, and the formation of sperm cells.


Located within the abdomen, the pancreas is each an endocrine gland and a digestive organ.

It releases:

  • Insulin: Important for carbohydrate and fats metabolism in the frame
  • Somatostatin: Regulates endocrine and nervous gadget function and controls the secretion of
  • numerous hormones, along with with gastrin, insulin, and increase hormone
  • Glucagon: A peptide hormone that increases blood glucose levels after they fall too low
  • Pancreatic polypeptide: This allows manipulate the secretion of materials made through the pancreas

Diabetes and digestive troubles can result if there are problems with the pancreas.

Parathyroid glands

These small endocrine glands placed in the neck produce parathyroid hormone, which regulates calcium and phosphate within the blood.
Muscles and nerves can handiest function accurately and efficaciously if these chemical compounds are at appropriate ranges.

The pineal frame, or pineal gland

This is a small endocrine gland positioned deep in the mind. It secretes melatonin and facilitates manage the body’s sleep styles and moderate degrees of reproductive hormones.

Pituitary gland

An endocrine gland connected to the hypothalamus at the base of the mind.

It is on occasion known as the primary endocrine master gland because it secretes hormones that adjust the features of different glands, as well as increase and numerous other bodily capabilities.

The anterior, or front, the pituitary secretes hormones that have an effect on sexual development, thyroid function, boom, pores and skin pigmentation, and adrenocortical function.

If the anterior pituitary is underactive, it may cause a stunted boom in formative years and interactivity in other endocrine glands.

The posterior, or rear, the pituitary secretes oxytocin, a hormone that will increase contractions of the uterus and antidiuretic hormone (ADH) which encourages the kidneys to reabsorb water.

Thymus gland

The thymus is an endocrine gland placed beneath the breastbone or sternum.

T lymphocytes, a kind of immune cell, mature and multiply inside the thymus gland early in life. After puberty, the gland shrinks.

The thymus gland performs a function inside the immune device, which protects the frame in opposition to ailment and contamination.

Thyroid gland

A butterfly-formed gland located simply beneath Adam’s apple within the neck, the thyroid produces hormones that play a key position in regulating blood pressure, body temperature, heart charge, metabolism, and the way the frame reacts to different hormones.

  • The thyroid gland uses iodine to create hormones.
  • The two primary hormones it produces are thyroxine and triiodothyronine.
  • It also produces calcitonin, which helps beef up bones and regulates the metabolism of calcium.
  • Below is a 3-D version of the endocrine device, which is absolutely interactive.
  • Explore the model the use of your mouse pad or touchscreen to understand extra approximately the endocrine machine.


A hormone imbalance can end result from genetic or environmental factors.

Some babies are born with hormonal problems that can lead to a range of health troubles, which includes low boom.

Endocrine-disrupting chemicals, along with pesticides, lead, and phthalates, which are used in plastic meal containers, can every so often lead to hormonal issues.

There are 3 broad corporations of endocrine disorders:

  • A gland does now not produce sufficient of its hormones. This is known as endocrine gland hyposecretion
  • A gland produces too much of its hormones, additionally known as hypersecretion.
  • Tumors develop within the endocrine glands. They can be malignant, or cancerous, however, they’ll also be benign, or non-cancerous.

What can go wrong?

Here are a few examples of what can occur if a gland secretes too much or too little of its hormones.

Adrenal Gland

  • Hypersecretion may additionally lead to over-nervousness, sweating, raised blood pressure, and Cushing’s disorder
  • Hyposecretion may additionally cause Addison’s disorder, Mineralocorticoid deficiency, weight loss, loss of energy, and anemia


Hypersecretion can also lead to hyperinsulinism, too much insulin can result in low blood glucose
Hyposecretion can also cause one form of diabetes

Parathyroid Gland

Hypersecretion may lead to brittle bones that fracture without problems, as well as stones in the urinary gadget
Hyposecretion may additionally lead to involuntary muscle contractions, or tetany, due to low stages of calcium in plasma

Thyroid Gland

Hyperthyroidism most customarily stems from Graves’ disorder. It can result in accelerated metabolism, sweating, arrhythmia or irregular heartbeat, weight loss, and nervousness.
Hypothyroidism may also result in tiredness, weight gain, depression, atypical bone development, developmental delay, and stunted increase.

Pituitary Gland

Hypersecretion might also result in gigantism or excessive increase
Hyposecretion may additionally cause slow bone increase and quick stature

Thymus Gland

Hypersecretion may result in an overactive immune device that overreacts to perceived threats. This might also bring about autoimmune disease.
Hyposecretion may additionally result in a weakened immune device, where the body is unable to fight infection and effortlessly succumbs to viruses, bacteria, and different pathogens.

Endocrinologists usually deal with the following situations:

  • diabetes
  • osteoporosis
  • menopause
  • metabolic disorders
  • thyroid sicknesses
  • immoderate or inadequate production of hormones
  • some cancers

  • dietary habits

It can help to list any existing signs and symptoms earlier than the visit.

The endocrinologist may ask about signs and symptoms that don’t appear to be related, or that seem unnecessary.

This is because hormone tiers have an effect on such a lot of exceptional systems inside the body that just small modifications in one gland can affect elements of the body far from the site of the glands themselves.
