Estrogen supplementation issues?


Hello, doctor.
My wife is around 40 years old and has been feeling fatigued and irritable over the past few years.
She exhibits some signs of hormonal deficiency (she hasn't seen a doctor; she researched online and feels it resembles hormonal deficiency).
A friend of hers went abroad and bought estrogen to give her (her friend suggested she take two pills daily after her period ends).
However, I read online that estrogen supplementation should be accompanied by progesterone to avoid an increased risk of certain cancers and tumor formation.
Should I advise her not to take it? Is there a dosage issue with estrogen, where exceeding a certain level poses risks? Or does she need to purchase progesterone to take alongside it? She believes she is not in menopause, so she hasn't seen a gynecologist.
Should the estrogen be evaluated by a doctor before taking it? (I lack knowledge in gynecology, so I'm unsure what to do.) I appreciate your time in addressing my concerns.
Thank you.

Hello, you cannot take estrogen alone; it must be combined with progesterone, otherwise it may increase the risk of certain cancers.
It is advisable for your wife to consult a gynecologist.
Wishing you good health.

When considering estrogen supplementation, especially for women around the age of 40, it is crucial to approach the situation with caution and a thorough understanding of the potential risks and benefits. Your concerns regarding your wife's hormonal health and the use of estrogen are valid and warrant careful consideration.

Firstly, it is important to recognize that estrogen plays a significant role in various bodily functions, including the regulation of the menstrual cycle, maintenance of bone density, and overall mood stabilization. However, as women approach perimenopause and menopause, they may experience symptoms related to hormonal fluctuations, such as fatigue, irritability, and mood swings, which you mentioned your wife is experiencing. While these symptoms can indeed be indicative of hormonal imbalance, self-diagnosing and self-treating with hormones without medical supervision can pose significant risks.

The use of estrogen, particularly in the form of supplements, should ideally be guided by a healthcare professional. This is because estrogen therapy can have side effects and potential risks, including an increased risk of certain types of cancer, particularly breast and endometrial cancer, especially if estrogen is taken without progesterone in women who have not undergone a hysterectomy. The addition of progesterone is essential in women with an intact uterus to counterbalance the effects of estrogen and reduce the risk of endometrial hyperplasia, which can lead to cancer.

Regarding the dosage of estrogen, it is indeed true that the risk associated with hormone therapy can vary based on the dosage and duration of treatment. Low-dose estrogen therapy may carry fewer risks compared to higher doses. However, the specific dosage and regimen should be tailored to the individual's health status, symptoms, and risk factors, which is why a medical evaluation is critical.

In your wife's case, since she has not seen a healthcare provider for her symptoms, it would be advisable for her to schedule an appointment with a gynecologist or an endocrinologist. A healthcare professional can perform a thorough assessment, which may include a physical examination, a review of her medical history, and possibly hormone level testing. This evaluation will help determine whether she is experiencing hormonal deficiency and whether estrogen supplementation is appropriate for her.

Additionally, if your wife is considering taking estrogen that was obtained from a friend, it is important to emphasize that medications should not be shared or taken without a prescription. The formulation, dosage, and delivery method of hormone therapy can vary significantly, and what may be appropriate for one individual may not be safe or effective for another.

In summary, while estrogen supplementation can be beneficial for managing symptoms of hormonal imbalance, it should be approached with caution. It is essential for your wife to consult with a healthcare provider who can provide personalized recommendations based on her specific health needs. This will not only ensure her safety but also optimize her treatment outcomes. Encouraging her to seek professional medical advice is the best course of action to address her symptoms and concerns regarding hormone therapy.
