You've probably heard the word "estrogen" before, right? We often think of it as a female hormone. But there are different types of estrogen. One of those types is "estrone" (sometimes called E1). So today, let's talk a little bit about estrone? Just like talking to a friend, simply.
So what is this Estrone?
Simply put, estrone is a sex hormone found in women's bodies. It is a member of the estrogen family of hormones. There are three main members of the estrogen family. They are:
- Estrone (E1): This is the one we're talking about today. This is the type of estrogen that continues to be produced by the body, especially after menopause, that is, after the monthly menstrual periods have stopped.
- Estradiol (E2): This is the main estrogen hormone that is present throughout a woman's life. It performs a number of important functions.
- Estriol (E3): This type of estrogen increases most during pregnancy.
Now you understand what estrone is? After menopause, most women's estradiol levels decrease, but some estrone continues to be produced. Therefore, postmenopausal women usually have slightly higher estrone levels than premenopausal women. Don't be surprised, men also have very small amounts of estrone in their bodies!
Where is this estrone produced?
Like other estrogens, estrone is produced primarily in the adrenal glands and adipose tissue . Yes, you are right, it is also produced in the body's fat deposits, or adipose tissue. In addition, estrone is also produced in women's ovaries . However, after menopause, estrogen production from the ovaries decreases significantly, so the fat tissue and adrenal glands are the main producers of estrone.
What happens to Estrone? Why is this important?
Estrone is a member of the estrogen family, so it contributes to women's sexual function and reproductive health. However, it is not as strong as the estradiol we mentioned earlier. That means its "power" is a little less.
Think of it this way, estrone is like a "storage" of estrogen. When your body needs estrogen, it can sometimes convert this estrone into estradiol, a more potent form of estrogen. That is, it's like a "reserve" that can be used when needed.
What is the difference between Estrone and Estradiol?
We said that estrone can turn into estradiol when the body needs a stronger estrogen. So what happens to this estradiol ? It controls many important processes in the female reproductive system. For example:
- The release of a mature egg (ovulation) during the monthly menstrual cycle.
- Thickening of the inner wall of the uterus (endometrium) in preparation for fertilization.
In addition to these, both naturally occurring estradiol and estradiol derived from estrone help in many other ways. Some of these include:
- Maintaining bone health . These help keep bones strong.
- Cognitive function , which refers to brain functions such as memory and attention.
- Production of nitric oxide . This is a molecule that helps blood vessels dilate, or open up. Therefore, it is also good for blood circulation.
What problems can arise if estrone levels become irregular?
Experts still don't have a complete picture of what happens when estrone levels drop, but we do know some things.
Low estrogen levels (which also includes estrone) can increase the risk of developing osteoporosis , a bone-thinning disease. Low estrogen levels can also be a cause of the fatigue, hot flashes, and decreased sex drive that some people experience after menopause.
High levels of estrone are also not good. It may affect the development of some types of breast cancer and uterine cancer .
What causes increased estrone levels?
Some conditions can cause estrone levels to increase. We mentioned earlier that estrone is produced in adipose tissue. So, obesity , which means that body fat increases along with the increase in adipose tissue, can also increase estrone production. Other causes include:
- Breast cancer
- Treatments that lower testosterone levels (for example, some treatments for prostate cancer)
Things like these can also cause estrone levels to rise.
How do irregular estrogen levels affect the body in general?
Whether estrogen levels are low or high, it can cause some uncomfortable symptoms in both men and women.
Conditions that can occur due to low estrogen
If you're a woman, low estrogen can cause things like:
- Abnormal Uterine Bleeding (AUB)
- Difficulty falling asleep
- Dry skin
- Irregular menstruation
- Headaches that occur before menstruation (`Menstrual migraines`)
If you are a man, low estrogen can cause:
- Increased fat deposition in the abdominal area
- Decreased sexual desire
Things like that can happen.
Conditions that can be caused by high estrogen
High estrogen levels can also cause problems. If you are a woman:
- Depression or Anxiety
- Fatigue
- Excessive or scanty bleeding during menstruation
- Low libido
- Non-cancerous lumps in the breasts (`Fibrocystic breast changes`)
- Severe premenstrual syndrome (PMS)
- Uterine fibroids
- Weight gain in the hips, thighs, or waist area
Situations like this can occur.
If you are a man, excess estrogen can cause:
- Breast enlargement (`Gynecomastia`)
- Erectile dysfunction
- Infertility
Things like that can happen.
Think of it this way, these hormones are like a balance wheel. If one side is too high or too low, the whole balance can be thrown off. That's why it's important to keep them at the right level.
What lifestyle habits can you do to keep your estrone levels healthy?
We now know that hormonal imbalances can cause uncomfortable symptoms like fatigue, mood swings, and irregular bleeding. So, here are some things you can do to balance these hormones and keep your estrone levels in a healthy range:
- Eat a nutritious diet: Eat a balanced diet that includes whole grains, fruits, vegetables, healthy fats, and proteins.
- Regular exercise: Include both cardiovascular exercise and resistance training, such as weight lifting.
- Managing stress: Manage stress through methods such as talk therapy or meditation.
- Get at least seven hours of sleep a night: Practice healthy sleep habits. For example, stop using electronic devices at least an hour before bed.
These things have a positive effect on your overall health and hormonal balance.
Is Estrone also used as a medicine?
Yes, there are cases. Although estrone is a hormone that we all produce naturally in our bodies, it is sometimes used as part of medical treatment. In particular, if the symptoms of menopause (e.g. excessive sweating, insomnia) are severe enough to interfere with daily life, doctors may prescribe hormone replacement therapy (`Hormone Therapy - HT`) containing estrone. However, this type of treatment is not suitable for everyone, so it should be taken only under medical advice.
Take-Home Message
Okay, so let's recap some of the things we talked about today about estrone that we think are important to you:
- Estrone is a member of the estrogen hormone family. Although not as potent as estradiol, it plays an important role.
- This is the main type of estrogen that continues to be produced in the body even after menopause.
- Estrone is produced mainly in the adrenal glands and adipose tissue.
- Depending on the need, estrone can be converted to the more potent estradiol.
- Low or high estrone levels can cause various health problems and uncomfortable symptoms (such as irregular bleeding, fatigue, mood swings, and insomnia).
- A healthy lifestyle (good diet, exercise, stress management, adequate sleep) helps balance hormone levels, including estrone.
- In some cases, estrone is also used as a medication for hormone therapy (HT) .
So, if you have any of these symptoms, or if you have any concerns about your hormone levels, the best thing to do is to see a doctor for advice. They can figure out exactly what's going on with you and give you the necessary treatment or advice. Got it? It's very important for all of us to take care of our bodies.
