Symptoms of an elevated progesterone level

Progesterone, often referred to as the "pregnancy hormone," is one of the sex hormones and plays a central role in both women and men. But what happens when hormone levels become imbalanced? Elevated progesterone levels can cause surprising and often bothersome symptoms that many people do not associate with this hormone – from fatigue and mood swings to physical changes. In this blog, you will learn more about progesterone. The most common symptoms, causes, consequences, and treatment options for elevated progesterone levels will be discussed to help maintain your health and well-being.

What is progesterone?

Progesterone is a naturally occurring hormone:

In women, progesterone is primarily produced in the ovaries (corpus luteum) after ovulation. During pregnancy, the placenta takes over the production of the hormone. Small amounts of progesterone are also produced in the adrenal glands (Cable JK. et al., 2023). In men, progesterone is also produced in the adrenal glands and the testes (Oettel M. et al. 2004).

Functions of progesterone:
Progesterone plays a crucial role in the female reproductive system. It regulates the menstrual cycle by thickening the uterine lining and preparing it for the implantation of a fertilized egg. During pregnancy, progesterone levels continue to rise. High progesterone levels prevent ovulation during pregnancy. The hormone also prevents premature labor (uterine contractions) by relaxing the muscles of the uterus. Finally, progesterone helps prepare the breasts for breastfeeding (Cleveland Clinic, 2022).

Although progesterone is produced in much smaller amounts in men, it has important functions. Among other things, progesterone plays a role in sperm production, serves as a precursor hormone for the production of other important hormones such as testosterone and cortisol, and thus contributes to hormone balance (Barros L.A. et al., 2015). In addition, progesterone affects the central nervous system, can regulate mood and sleep, and has an impact on the immune system, cardiovascular system, kidney function, fat tissue, behavior, and respiratory system (Oettel M., et al., 2004).

What are elevated progesterone levels?

Elevated progesterone levels occur when progesterone levels rise above the normal range. Normal progesterone levels vary depending on the phase of the menstrual cycle and whether or not a woman is pregnant. High progesterone levels are usually normal in the second half of the menstrual cycle (luteal phase) and during pregnancy.

Normal progesterone levels (ng/mL):

Follicular phase: The first half of the menstrual cycle, starting with the first day of menstruation and ending with ovulation.
Luteal phase: The second half of the menstrual cycle, starting after ovulation and ending at the beginning of the next menstruation.
Trimester: Pregnancy is divided into trimesters. One trimester corresponds to three months.

Causes of elevated progesterone levels

Several factors can lead to elevated progesterone levels. It is important to understand the causes to take appropriate treatment measures:

• Pregnancy: During pregnancy, progesterone levels rise significantly. Elevated progesterone levels outside the normal range during pregnancy may indicate a twin pregnancy or an abnormal pregnancy (University of Rochester Medical Center, n.d.).

• Adrenal overactivity: The adrenal glands produce a variety of hormones, including progesterone, and overactivity of the adrenal glands can lead to elevated progesterone levels (Krucik G., 2017).

• Hormone therapy: Some women receive progesterone as part of hormone replacement therapy to treat menopause symptoms or as part of fertility treatments to promote ovulation and implantation.

• Cysts: (Cyst = a fluid-filled cavity in tissue, consisting of tissue fluid, blood, and a pasty component). Certain types of ovarian cysts, especially so-called luteal cysts, can increase progesterone production. These cysts form after ovulation and can continuously release progesterone (MedlinePlus, 2022).

• Tumor: Elevated progesterone levels, even when not pregnant, may indicate an ovarian tumor known as a lipid ovarian tumor or choriocarcinoma (University of Rochester Medical Center, n.d.).

Symptoms of elevated progesterone levels

High progesterone levels generally do not have negative health effects (Cleveland Clinic, 2022). In some cases, however, elevated progesterone levels can cause a variety of symptoms. These symptoms can vary individually and depend on the underlying cause of the elevated progesterone level.

Common symptoms include:

• Swollen or tender breasts

• Mood swings, anxiety or restlessness, depression

• Bloating

• Fatigue

• Decreased libido

• Weight gain

Are you experiencing any of these symptoms or would like clarity about your hormonal health?

Do you feel tired or notice changes in your mood? These symptoms could point to a hormonal imbalance. With the women's hormone test from Homed-IQ, you can find out whether your symptoms are caused by elevated progesterone levels or other hormonal irregularities. The test measures important hormones such as testosterone, TSH, LH, FSH, estradiol, and prolactin, which affect fertility, the menstrual cycle, and overall health. This easy-to-use hormone test, which can be performed at home, provides insight into related symptoms. On our website, you can also find other important women’s health tests, such as a fertility test. This way, you can take targeted action and take charge of your health.

How are elevated progesterone levels treated?

Treatment of elevated progesterone levels depends on the underlying cause and the severity of symptoms. An individual treatment plan is important to restore hormonal balance and improve quality of life.

• Hormonal/medicinal treatment: In some cases, hormonal or medicinal therapy by a doctor may be necessary to regulate progesterone levels. For example, the dosage of hormone preparations may be adjusted or the type of preparation changed.

• Lifestyle changes: A healthy diet, regular exercise, and effective stress management can help stabilize hormone levels. Studies have shown that giving up coffee and smoking can lower progesterone levels (Herrera A. Y., et al., 2016; Kotsopoulos J., et al., 2009; Zumoff B., et al., 1990).

• Monitoring and regular tests: Regular blood tests at home or with a trusted doctor can help monitor progesterone levels and ensure they remain within the normal range.

Summary

Progesterone is a naturally occurring hormone present in both women and men. Elevated progesterone levels can cause a variety of symptoms and health issues, such as mood swings, bloating, or fatigue, which are often not associated with this diagnosis. Causes of elevated levels may be pregnancy-related, but in rare cases, they can also stem from adrenal overactivity or cysts. Suitable treatment options range from medical therapy to lifestyle changes. Monitoring and regulating progesterone levels can alleviate many unpleasant symptoms and improve quality of life.
