4 Different Hormones And Their Function

Read our complete guide on 4 different hormones and their function

Hormones are a key ingredient of the human body. They are chemical messengers who carry different messages from the brain to multiple organs, tissues, and cells. They regulate multiple processes inside the body which is why a balance in their levels is crucial. In this article, let us explore the four crucial hormones and the functions they perform.


  • It is the primary female sex hormone that is majorly produced in the ovaries, but little quantities are also manufactured in the adrenal glands and fat cells. This hormone is responsible for multiple processes that occur inside the female body such as menstruation, menopause, regulation of sex drive, causing pregnancy, and maintaining blood and bone health.

Estrogen levels fluctuate with age and throughout the menstrual cycle. Estrogen is an important hormone and too much or too little of it can cause multiple health issues such as:

  • Excess of estrogen can cause a higher susceptance to breast and urine cancer. It also increases the disposition to depression and moodiness.
  • Low levels of estrogen are triggers for the development of acne, premature hair loss, and thinning skin.

When a female reaches menopause, the levels of estrogen go down drastically. It can lead to multiple issues such as:

These issues can be treated by Female Hormone Replacement Therapy by restoring estrogen levels to their optimum quantity.


This is the primary male sex hormone that is produced in the testicles. However, the ovaries and adrenal glands in the female body also produce this hormone in low quantities. Testosterone contributes to muscle strength, bone mass, fat distribution, production of red blood cells, and regulating sex drive. However, an excess of testosterone in the female body causes multiple issues such as:

  • Development of acne
  • Androgenic alopecia
  • Growth of thick facial hair
  • Low libido
  • Irregular periods
  • Reduction in breasts


Insulin is an important hormone that is produced by the pancreas. It performs the following functions:

  • Regulates the amount of glucose in the bloodstream and prevents the sugar levels from getting too high (hyperglycemia) or too low (hypoglycemia).
  • Stores glucose in the liver and muscles.
  • Controls the metabolism of carbohydrates, fats, and proteins.

Diabetes is caused when the body does not produce enough insulin or the insulin cannot be processed by the body correctly. Diabetes is a common disease that affects 9.4% of people in the US.



  • The fourth important hormone on the list is adrenaline that is secreted by the adrenaline gland and works on the nervous system. Adrenaline gives an extra burst of physical energy and mental clarity during dangerous, life-threatening situations. Hence, it is known as the fight or flight hormone. When adrenaline is released, it sends a rush of blood to the heart and muscles to cope with the situation at hand.

Adrenaline also acts as a pain blocker. During crucial moments adrenaline numbs the body’s ability to feel the pain to fight the obstacle better. The effects of adrenaline can stick around for one-hour maximum.

Overproduction of adrenaline, due to continual stress, has multiple side effects such as the following:

  • High blood pressure
  • Palpitations
  • Increased heart rate
  • Anxiety
  • Dizziness
  • Irritability
  • Weight loss
