Hormonal Treatments for Endometriosis: What Are Your Options?

Endometriosis affects one in ten women of reproductive age globally, and many women in Singapore suffer in silence due to lack of awareness and stigma. One of the most common and effective ways to manage this painful condition is through hormonal treatments for endometriosis. These treatments help slow the growth of endometrial-like tissue, reduce inflammation, and ease the intense pelvic pain many women experience.

If you have recently been diagnosed or are exploring alternatives to surgery, understanding your hormonal treatment options can empower you to make informed choices about your health.

What Is Endometriosis and Why Hormones Matter

Endometriosis occurs when tissue similar to the uterine lining grows outside the uterus, often on the ovaries, fallopian tubes, bladder or bowel. This displaced tissue behaves just like normal endometrial tissue—it thickens, breaks down and bleeds during your menstrual cycle. However, with no way to exit the body, the tissue becomes trapped, causing inflammation, severe pain, and even infertility in some cases.

Hormonal treatments aim to control the oestrogen levels in your body. Oestrogen fuels the growth of endometrial tissue, so reducing or regulating it can ease symptoms and slow the progression of the condition.

Types of Hormonal Treatments for Endometriosis

In Singapore, gynaecologists commonly recommend the following hormone-based therapies to manage endometriosis:

1. Combined Oral Contraceptives (COCs)

COCs contain both oestrogen and progestin. They are usually the first line of hormonal treatment, especially for younger women or those with mild to moderate symptoms.

Benefits:

• Regulates menstrual cycles
• Reduces menstrual flow
• Relieves pelvic pain and cramping

COCs can be taken continuously (skipping the placebo pills) to suppress menstruation altogether, which is especially helpful in managing chronic pain caused by endometriosis.

2. Progestin-Only Therapy

These treatments use synthetic progesterone (progestin) to thin the endometrial lining and suppress ovulation.

Forms available in Singapore:

• Oral tablets (e.g. Dienogest)
• Intrauterine devices (e.g. Mirena IUD)
• Progestin injections (e.g. Depo-Provera)

Why it works:
Progestin limits the growth of endometrial tissue and can even reduce existing lesions over time. It’s a suitable option for women who cannot tolerate oestrogen or prefer long-acting solutions.

3. Gonadotropin-Releasing Hormone (GnRH) Agonists and Antagonists

These drugs put the body into a temporary menopausal state by reducing the production of oestrogen and other reproductive hormones.

Examples used in Singapore:

• GnRH agonists like Leuprorelin (Lucrin)
• GnRH antagonists like Elagolix

Side effects to consider:

• Hot flashes
• Mood changes
• Bone density loss (with long-term use)

To counteract these side effects, doctors may prescribe “add-back therapy”, which includes low-dose hormones to protect bone health without reducing the treatment’s effectiveness.

4. Danazol

Danazol is a synthetic steroid that blocks the release of hormones responsible for ovulation. While less commonly used today due to side effects, it remains an option for some women who do not respond well to other therapies.

Possible side effects:

• Weight gain
• Acne
• Voice deepening

Due to these androgenic effects, danazol is typically used as a short-term solution and under close medical supervision.

Choosing the Right Treatment Option in Singapore

The best hormonal treatment for endometriosis depends on several factors:

• Your age
• Severity of symptoms
• Whether you want to preserve fertility
• How your body responds to different medications

Singapore offers access to a wide range of specialists and treatment options through both public and private clinics. Many treatments are partially claimable under Medisave, especially if prescribed as part of a surgical or inpatient procedure. It’s important to speak with a doctor who specialises in endometriosis to find the approach that best suits your body and lifestyle.

Risks and Considerations

While hormonal therapy helps manage symptoms, it is not a cure. Endometriosis may return once the treatment stops. Some women also experience side effects like mood swings, nausea, or irregular bleeding, which may influence treatment decisions.

Gynaecologists in Singapore often monitor your condition over time to adjust the treatment plan or combine it with other strategies such as dietary changes, physiotherapy, or minimally invasive surgery.

Find the Right Endometriosis Treatment for You

Hormonal treatments for endometriosis offer effective symptom relief and help many women experience a better quality of life. Whether you’re just starting your treatment journey or thinking about switching to a different method, it’s important to speak with your doctor and understand what your body needs.
