Dear online user,
1.
In medical terms, the so-called female hormones refer specifically to animal-derived hormones, which can be divided into two types: estrogens and progesterone.
These can be naturally extracted or chemically synthesized.
2.
The so-called plant-based hormones available on the market are derived from soy products and are classified as nutritional supplements rather than medications.
Therefore, their composition and efficacy are less certain, and they are relatively less likely to be absorbed in large quantities, which could lead to severe side effects.
3.
Possible side effects of female hormones include the following:
1.
Cardiovascular system: Increased blood pressure.
2.
Urogenital system: Vaginal bleeding, breast tenderness; long-term use may increase the incidence of breast cancer.
3.
Gastrointestinal tract: Nausea, bloating, abdominal pain, cholestasis-related gallbladder disease, jaundice.
4.
Skin: Hair loss, rashes, hirsutism, itching.
5.
Nervous system: Visual disturbances, headaches, nervousness.
6.
Others: Weight gain or loss, edema.
Wishing you good health,
Liang Yin-Pan, Changhua Hospital

More Info

When it comes to the choice between animal-based and plant-based hormones for women's health, it's essential to understand the differences, benefits, and potential side effects associated with each type.
Animal-Based Hormones:
Animal-based hormones, primarily derived from the ovaries of pregnant mares or synthesized to mimic these hormones, include estrogen and progesterone. These hormones are often used in hormone replacement therapy (HRT) for women experiencing menopause or those who have undergone surgical procedures such as hysterectomy. The primary benefits of animal-based hormones include:
1. Effectiveness: They are generally more potent and have a more predictable effect on the body compared to plant-based alternatives. This can be particularly beneficial for managing severe menopausal symptoms such as hot flashes, night sweats, and mood swings.

2. Bone Health: HRT with animal hormones can help prevent osteoporosis, a condition that leads to weakened bones, which is particularly important for postmenopausal women.

3. Cardiovascular Health: Some studies suggest that HRT can have protective effects on heart health when started early in menopause.

However, the use of animal-based hormones is not without risks. Potential side effects include:
- Increased risk of breast cancer, particularly with long-term use.

- Elevated blood pressure and potential cardiovascular issues.

- Gastrointestinal disturbances such as nausea and bloating.

- Mood changes, headaches, and weight fluctuations.

Plant-Based Hormones:
Plant-based hormones, often referred to as phytoestrogens, are found in various foods, particularly soy products, legumes, and some grains. These compounds can mimic estrogen in the body but are generally considered weaker than their animal counterparts. The benefits of plant-based hormones include:
1. Natural Source: They are derived from natural foods, which may appeal to those seeking a more holistic approach to health.

2. Lower Risk of Side Effects: Because they are weaker than animal hormones, phytoestrogens are less likely to cause severe side effects. They may even provide a protective effect against certain hormone-related cancers.

3. Flexibility in Diet: Incorporating foods rich in phytoestrogens can be an easy addition to a balanced diet, making them accessible for many individuals.

However, there are considerations to keep in mind:
- The effectiveness of plant-based hormones can vary significantly among individuals, and they may not provide sufficient relief for severe menopausal symptoms.

- Some individuals may experience gastrointestinal discomfort or allergic reactions to certain plant-based foods.

Conclusion:
The choice between animal and plant hormones ultimately depends on individual health needs, preferences, and medical history. Women considering hormone therapy should consult with their healthcare provider to discuss their specific symptoms, risks, and benefits associated with each option.
For those who have undergone surgical procedures like hysterectomy or are experiencing severe menopausal symptoms, animal-based hormones may be more effective. Conversely, for those looking for a more natural approach or who have mild symptoms, incorporating plant-based hormones through diet may be beneficial.

In summary, both animal and plant hormones have their pros and cons, and the decision should be made based on a thorough discussion with a healthcare professional, taking into account personal health goals and risk factors. Regular monitoring and adjustments may be necessary to ensure the best outcomes for women's health.
