Have you ever wondered how many things happen inside your body without you even realizing it? Your breathing, your digestion, your feelings of happiness and sadness, all of these are caused by tiny messengers. We call those messengers hormones. They are like secret messages in our bodies, going from one place to another, telling us, 'Do this, do this.' So, shall we talk about these wonderful hormones today?
So what are these hormones?
Simply put, hormones are chemical messengers in our bodies. They travel throughout our bodies through our blood, telling our various organs, skin, and muscles to do this and that. Imagine that if our bodies were a big company, hormones would be like its managers, coordinating everything.
Did you know that scientists have already discovered more than 50 types of hormones in our bodies! These hormones are essential to our life and health. Together, these and the glands that produce them form our endocrine system . This system controls many important processes in our bodies. Here are a few examples:
- Metabolism: This is the process of converting the food we eat into energy.
- Homeostasis: This means the balance within the body (e.g. blood pressure, sugar level, body temperature).
- Growth and development: We grow from childhood.
- Sexual function and reproduction.
- Sleep-wake cycle: We fall asleep at night and wake up in the morning.
- Mood: Emotions such as whether we feel happy or sad.
It's amazing to think how much these little chemicals can do! In the case of hormones, even very small amounts can have a big impact. That's why even small changes in hormone levels can cause big changes in our bodies, sometimes even causing illnesses that require medical treatment.
So how do these hormones work in the body?
Okay, now we know that hormones are messengers. So how do these messages get sent? Who hears these messages?
Well, hormones are chemical messengers . They influence and manage hundreds of processes in our bodies. Often, a single process in the body requires the contribution of several hormones. Like links in a chain, one hormone sends a message to another, which in turn sends a message to another, and so on.
Now, for a hormone to affect only one part of the body, it has to be "just right." That is, the cells in the tissue that the hormone targets (it could be an organ, it could be fat tissue) must have special "receptors" that can accept the hormone's message. Think of it this way: a hormone is a key, and the cells in that target tissue are like keys that are made to fit that key. Just as the key can only open a door if it fits the key, the hormone only works if it fits that receptor. That's when the hormone sends the message and tells that target to do something. Do you understand?
Although it may seem very simple, this is an amazing mechanism! The "switch" that works for each hormone is only in its corresponding place. That's why one hormone does only what it is supposed to do, without affecting the entire body.
Our bodies use hormones in two ways to communicate.
1. The first method is communication between two endocrine glands: One gland releases a hormone, which then goes on to stimulate another gland to change the levels of the hormone it releases. A good example is the relationship between your pituitary gland and your thyroid gland . The pituitary gland releases something called thyroid-stimulating hormone (TSH) . This TSH goes on to tell the thyroid gland to "release your hormones."
2. The second method is communication between an endocrine gland and a target organ: For example, your pancreas releases a hormone called insulin . This insulin goes to your muscles and liver, helping them use a type of sugar called glucose .
This is how hormones work inside our bodies. It's like a complex network, isn't it?
Who makes these valuable hormones? Where are they produced?
The main places in our body that make hormones are the glands of the endocrine system . Let's quickly take a look at some of them and their main functions:
Hypothalamus
Located in the brain, this gland controls the pituitary gland and produces hormones like oxytocin (also known as the love hormone).
Pituitary Gland
This 'master gland' located under the brain produces many important hormones, such as growth hormone (GH) , and also controls other glands.
Pineal Gland
This hormone in the brain produces melatonin and controls our sleep-wake cycle.
Thyroid Gland
This gland in the neck produces thyroid hormones (T3, T4) and controls our body's metabolism , that is, the rate at which we use energy.
Parathyroid Glands
These glands, located behind the thyroid, produce parathyroid hormone (PTH) to maintain blood calcium levels and bone health.
Adrenal Glands
These glands, located on the kidneys, produce hormones such as cortisol ( a hormone that responds to stress) and adrenaline (a hormone that acts in emergency situations).
Pancreas
This gland in the stomach is responsible for making insulin and glucagon and controlling blood sugar levels.
Ovaries
These glands in women produce reproductive hormones like estrogen and progesterone .
Testicles (Testes)
These in men produce the main male hormone, testosterone .
In addition to these glands, there are other places that do not belong to the endocrine system, but that make hormones:
- Adipose tissue: Fat in the body produces hormones like leptin , which affect appetite.
- Kidneys: Produce hormones such as erythropoietin, which helps make red blood cells. Vitamin D (which is actually a prohormone) is also activated here.
- Liver: Produces insulin-like growth factor 1 (IGF-1), which is related to growth.
- Gut: Produces hormones such as ghrelin and glucagon-like peptide 1 (GLP-1) , which control hunger and appetite.
- Placenta: Produces hormones to maintain the pregnancy during pregnancy.
Look at how many places in our bodies produce and release these messengers called hormones! We are healthy because all of these things work in perfect coordination.
What happens if there are hormonal problems?
If there is a deficiency or excess of these important hormones, that is, if there is a 'hormonal imbalance' , various symptoms can appear and health problems can arise. In most cases, this requires medical treatment. Some of the most common hormone-related conditions are:
- Diabetes: This is mainly caused by a problem with the function or production of the hormone insulin. There are also types such as Type 2 diabetes , Type 1 diabetes, and Gestational diabetes .
- Thyroid disease: This includes low thyroid hormone levels ( hypothyroidism ) and high thyroid hormone levels ( hyperthyroidism ).
- Irregular menstrual cycles: This can be caused by conditions such as polycystic ovary syndrome (PCOS) , complete absence of menstruation ( amenorrhea ), and lack of ovulation ( anovulation) .
- Female infertility and male infertility: Low testosterone levels, especially in men ( hypogonadism) .
- Obesity: This can also be affected by hormonal imbalances.
There are many other conditions like this that are caused by hormonal problems. Therefore, it is very important to pay attention to anything unusual or different in your body.
Why do these hormonal imbalances occur?
There can be many causes for each hormonal disorder. But in general, here are some of the main causes of hormonal imbalances:
- Tumors, adenomas, or other growths: Sometimes these can develop in or around the endocrine glands and affect hormone production.
- Damage or injury to an endocrine gland.
- Autoimmune conditions: This is when our own immune system attacks our own endocrine glands.
- Hereditary gene mutations: Sometimes hormonal problems can be caused by genetic changes that are present at birth.
In addition to this, things like certain medications, severe stress, nutritional deficiencies, and aging can also affect hormone levels.
Who treats a hormone-related illness?
If you think you have a hormone problem, you should first see your family doctor (Primary healthcare provider/GP) . He or she can diagnose and treat many hormone conditions and help you manage them.
However, sometimes you may benefit more from seeing an endocrinologist . An endocrinologist is a doctor who specializes in hormone-related diseases (endocrinology) . He or she can diagnose these hormone-related diseases, develop treatment plans, and prescribe medications if necessary. So, if your family doctor thinks it's necessary, he or she will refer you to an endocrinologist.
So, what's the most important thing to remember from what we've talked about today?
Simply put, hormones are essential to our lives. Our bodies normally try to maintain a careful balance of these hormones. However, if for some reason a hormone becomes too low or too high, it can cause health problems .
Therefore, if you notice any unusual symptoms or changes in your body, do not ignore it. Definitely see a doctor and talk about it. Then he can do the necessary tests to see if you really have a hormonal imbalance, or if there is some other reason behind these symptoms. If you identify it early, many problems can be easily solved. If we want to stay healthy, it is very important for us to be aware of these little messengers, right?
