Hormonal Treatments for Fibroids
Fibroids are non-cancerous growths that develop in or around the uterus, often causing debilitating symptoms such as heavy periods and pelvic pressure. At Kinvara Private Hospital, we provide specialist hormonal treatments as a primary non-surgical option to manage these symptoms and improve your daily quality of life.

For many women in Rotherham, Sheffield, and the surrounding Rotherham areas, uterine fibroids (leiomyomas) can cause years of physical discomfort and heavy menstrual bleeding. Because fibroids are highly sensitive to the hormones oestrogen and progesterone, targeted hormonal therapy can effectively 'turn down' the signals that cause them to grow.
At Kinvara Hospital, our expert gynaecologists offer a range of hormonal pathways tailored to your specific symptoms. Whether you are looking to manage heavy flow with a hormone-releasing IUD, regulate your cycle with oral contraceptives, or shrink larger fibroids using GnRH agonists ahead of a planned procedure, we provide a supportive environment to explore these non-invasive solutions.
Am I a Candidate for Hormonal Treatment?
• Confirmed fibroids causing heavy menstrual bleeding, pelvic pressure, or pain
• Mild to moderate symptoms that interfere with quality of life
• Preference for non-surgical management
• Approaching menopause (when fibroids will naturally shrink)
• Need for fibroid shrinkage before planned surgery (GnRH agonists)
• No current plans for pregnancy (most hormonal treatments suppress fertility while in use)
• No medical contraindications to hormonal therapy (e.g., history of blood clots, certain cancers, severe liver disease)
Hormonal treatments work best for symptom management rather than as a permanent solution. Our consultants will assess your fibroid size, location, symptoms, and fertility goals to recommend the most appropriate treatment pathway.
Managing Fibroids Non-Surgically
Hormonal treatments are designed to manage the symptoms of fibroids rather than provide a permanent cure. By regulating or blocking the hormones that stimulate fibroid cells, these medications can significantly reduce the blood supply to the fibroids, leading to a reduction in size and a marked decrease in menstrual flow. This approach is often ideal for women approaching menopause or those who wish to avoid surgery.
Fibroids are clearly linked to reproductive hormones - oestrogen and progesterone. Fibroid cells contain more hormone receptors than normal uterine muscle cells, causing them to thrive when hormone levels are high. Fibroids often grow during pregnancy and typically shrink after menopause when hormone production naturally decreases.

The Procedure
There are several hormonal treatment options for fibroids, each with different mechanisms and applications. Your consultant will recommend the most suitable option based on your symptoms, fibroid size and location, medical history, and fertility plans.
- 1
**Hormone-Releasing IUD (Mirena/Levonorgestrel IUD):** Often the first-line treatment for heavy menstrual bleeding caused by fibroids. The IUD releases progestin directly into the uterine lining, dramatically reducing blood flow and cramping. It does not typically shrink fibroids but provides excellent symptom control for up to 5 years with minimal systemic side effects.
- 2
**Combined Oral Contraceptive Pills:** The pill can help regulate menstrual cycles and reduce heavy bleeding. While it doesn't shrink fibroids, it creates a more stable hormonal environment that can alleviate cramping and make periods more manageable. Suitable for women with smaller fibroids who also need contraception.
- 3
**Progestogen-Only Treatments (Pills or Depot Injections):** These create a progesterone-dominant environment that can thin the uterine lining and reduce bleeding. The depot injection (given every 12 weeks) may also provide some fibroid shrinkage but can cause irregular bleeding initially.
- 4
**GnRH Agonists (Goserelin, Leuprorelin):** The most potent hormonal option, given by injection every 4-12 weeks. These medications temporarily shut down the ovaries, creating a 'medical menopause' that dramatically reduces oestrogen levels. This can shrink fibroids by up to 50% within 2-3 months, making them ideal for pre-surgical preparation. Due to menopausal side effects (hot flushes, bone thinning), they are usually limited to 6 months of use with 'add-back' HRT to minimize symptoms.
- 5
**Tranexamic Acid:** While not hormonal, this medication is often used alongside hormonal treatments to specifically target heavy bleeding. It works by reducing the breakdown of blood clots in the uterus, making periods lighter and more manageable.
- 6
**Ongoing Monitoring:** Regular follow-up appointments with ultrasound scans assess fibroid size, symptom improvement, and treatment effectiveness. Our team adjusts your treatment plan as needed to achieve optimal results.
What to Expect During Treatment
Recovery Timeline
First Month
Initial side effects such as irregular bleeding, spotting, or mild nausea are common as your body adjusts to the hormones. IUD insertion may cause cramping for a few days. These symptoms usually settle within 4-6 weeks.
1-3 Months
Gradual reduction in heavy bleeding and cramping. Most women notice significant improvement by the second or third menstrual cycle. GnRH agonists begin shrinking fibroids during this period.
3-6 Months
Maximum symptom control achieved. Heavy bleeding is substantially reduced or eliminated. For GnRH agonist therapy, this is typically the end of treatment, after which you'll transition to maintenance therapy or prepare for surgery if planned.
6 Months+
Long-term maintenance with IUD or oral contraceptives continues to provide symptom relief. Regular check-ups monitor fibroid growth and treatment effectiveness. Many women continue hormonal management for years until menopause or until they choose surgical treatment.
Key Recovery Points
- Take medications as prescribed - consistency is key for symptom control
- Keep a menstrual diary to track bleeding patterns and symptom improvement
- GnRH agonists are temporary treatments (typically 3-6 months) due to side effects
- Fibroids often return to original size after stopping GnRH agonists
- IUDs and oral contraceptives can be used long-term for ongoing symptom management
- Report any severe side effects or worsening symptoms to your consultant immediately
Risks and Side Effects
Hormonal treatments for fibroids are generally safe and well-tolerated. Side effects vary depending on the type of treatment used. Our specialists will discuss the specific risks relevant to your chosen therapy.
Irregular Bleeding
Breakthrough bleeding or spotting is very common in the first 3-6 months, particularly with IUDs and progestogen treatments. This usually settles with time but can be bothersome initially.
Menopausal Symptoms (GnRH Agonists)
Hot flushes, night sweats, vaginal dryness, and mood changes are expected with GnRH agonists due to low oestrogen. 'Add-back' HRT minimizes these effects while maintaining fibroid shrinkage.
Mood Changes
Some women experience mood swings, anxiety, or low mood on hormonal treatments. These can usually be managed by switching to a different option.
Bone Density Loss
GnRH agonists can cause reversible bone thinning if used long-term without add-back HRT. This is why their use is limited to 6 months maximum.
Weight Gain
Modest weight gain is possible with progestogen-based treatments and depot injections, though this varies widely between individuals.
Fibroid Regrowth
After stopping GnRH agonists, fibroids typically return to their original size within 3-6 months. Hormonal treatments provide temporary symptom relief rather than permanent fibroid removal.
