Imagine your body is a giant kingdom. To keep things running smoothly, the king (or queen) needs to send messages to all the different towns and cities (your organs and tissues). These messages are carried by special messengers called hormones.

Hormones are like tiny mail carriers. They’re made by special glands in your body and travel through your bloodstream. When they reach their destination (a specific organ or tissue), they fit into a special lock like a key. This unlocks instructions for the cells, telling them what to do, like grow taller, use energy from food, or even change your mood.

In this blog, we’ll discuss these topics:

What are hormones and how they work

Hormones are chemicals in the body that act like messengers. They are made by special glands called endocrine glands. These chemicals travel through the blood to different parts of the body, telling organs and tissues what to do.

How Do Hormones Work?

  1. Made by Glands: Hormones are made in places like the pituitary gland, thyroid gland, adrenal glands, pancreas, ovaries, and testes.
  2. Travel in Blood: After they are made, hormones go into the blood and move around the body.
  3. Target Cells: Hormones find and attach to special cells called target cells. These cells have receptors that match the hormone.

The different types of hormones and their functions

Hormones are categorized into three main types based on their chemical structure: peptide hormones, steroid hormones, and amino acid-derived hormones. Each type has distinct functions in the body.

1. Peptide Hormones

Peptide hormones are made of amino acids. They are usually water-soluble and bind to receptors on the surface of target cells.

Examples and Functions

  • Insulin: Lowers blood sugar by helping cells absorb glucose.
  • Glucagon: Raises blood sugar by signaling the liver to release stored glucose.
  • Growth Hormone (GH): Promotes growth and cell reproduction.
  • Antidiuretic Hormone (ADH): Helps the kidneys manage water balance by reducing urine production.
  • Oxytocin: Causes uterine contractions during childbirth and helps with milk ejection during breastfeeding.

2. Steroid Hormones

Steroid hormones are derived from cholesterol. They are lipid-soluble and can pass through cell membranes to bind to receptors inside the cell.

Examples and Functions

  • Cortisol: Helps the body respond to stress, regulates metabolism, and controls inflammation.
  • Aldosterone: Regulates sodium and potassium balance, affecting blood pressure.
  • Estrogen: Controls female reproductive development and functions, including the menstrual cycle.
  • Testosterone: Controls male reproductive development and functions, including sperm production and muscle mass.
  • Progesterone: Prepares the uterus for pregnancy and supports early stages of pregnancy.

3. Amino Acid-Derived Hormones

These hormones are made from single amino acids. They can be either water-soluble or lipid-soluble.

Examples and Functions

  • Thyroxine (T4) and Triiodothyronine (T3): Produced by the thyroid gland, these hormones regulate metabolism, energy levels, and growth.
  • Epinephrine (Adrenaline): Produced by the adrenal medulla, it prepares the body for a ‘fight or flight’ response by increasing heart rate, muscle strength, and blood pressure.
  • Norepinephrine: Works alongside adrenaline to manage stress and regulate mood, alertness, and concentration.
  • Melatonin: Produced by the pineal gland, it regulates sleep-wake cycles and seasonal biological rhythms.

What are hormonal imbalances and how they can affect your health

Hormonal imbalances occur when there is too much or too little of a hormone in the bloodstream. Because hormones regulate many essential processes in the body, even small imbalances can have significant effects on health.

Causes of Hormonal Imbalances

  1. Medical Conditions: Disorders like diabetes, thyroid disorders, and adrenal gland disorders.
  2. Lifestyle Factors: Poor diet, stress, lack of exercise, and inadequate sleep.
  3. Medications: Hormonal medications, such as birth control pills or hormone replacement therapy.
  4. Environmental Toxins: Exposure to endocrine-disrupting chemicals in plastics, pesticides, and other products.
  5. Aging: Natural changes in hormone levels as people age, such as menopause in women and andropause in men.

Common Hormonal Imbalances and Their Effects
