Estriol

What's 
E3
?
Estriol (E3) is a type of estrogen, a hormone mainly linked to female reproductive health. It's especially important during pregnancy, as it's mostly produced by the placenta - the organ that provides nourishment to the baby. E3 plays a crucial role in keeping a pregnancy healthy, helping the uterus grow and getting the mother's body ready for labor and breastfeeding. When not pregnant, E3 is present in smaller amounts, but it still contributes to the overall balance of estrogen in the body. It's an interesting hormone that highlights the complex connections between the body's systems during one of life's most incredible experiences - pregnancy.
If Your Levels Are High
Elevated E3 levels might mean that there's a hormonal imbalance in your body, which could be caused by various factors. For example, as you age, your body's natural hormone production can change, or stress and unhealthy lifestyle choices, like eating lots of processed foods, might disrupt your hormone balance. Some medications, like hormone replacement therapy drugs, can also affect your E3 levels. Additionally, certain health conditions, such as liver disease or obesity, might make it harder for your body to break down hormones, leading to higher E3 levels. Keep in mind that these are just some possible reasons for increased E3, and each person's hormone balance is influenced by their own unique factors.
Symptoms of High Levels
Symptoms of high levels of E3 could include mood swings, fatigue, weight gain, bloating, and irregular menstrual cycles.
If Your Levels are Low
Low E3 levels might mean that there's an imbalance in the body's estrogen levels, which could be caused by various factors like age, stress, or certain lifestyle choices. For example, not getting enough essential nutrients from your diet or not being active enough could lead to lower E3 levels. Some medications, especially those that affect hormones, might also be involved. Additionally, conditions like thyroid disorders or adrenal fatigue could be affecting E3 levels. It's important to keep in mind that our bodies are complex, and hormone levels can be influenced by many different things happening inside and outside of our bodies.
Symptoms of Low Levels
Symptoms of low levels of E3 might include fatigue, mood swings, hot flashes, and difficulty concentrating.
