Understanding Bleeding During Continuous HRT in Menopause

Understanding Bleeding on Continuous HRT

Bleeding during continuous HRT can be distressing and confusing for many women. It is typically not a period but rather ‘breakthrough’ bleeding, which can occur at any point. This type of bleeding varies in frequency and intensity and should ideally diminish over time as the body adjusts to HRT. It may be as a result of:

• Endometrial Stimulation: Oestrogen stimulates the lining of the womb, which can lead to bleeding if overly thickened.
• Progestogen Balance: The type and dose of progestogen can influence bleeding patterns.
• Abnormalities in the genital tract and pelvis: With a decrease in estrogen, the tissue of the vulva, vagina and cervix can become more delicate and prone to bleeding. Other lesions can cause bleeding including sexually transmitted infection. This is why it is so important any unexpected bleeding is checked by your doctor.

Common Causes of Bleeding on Continuous HRT

Experiencing bleeding while undergoing continuous hormone replacement therapy (HRT) can be concerning for many, but there are several factors that may contribute to this issue:

• Hormonal Imbalance: One of the primary reasons for bleeding on continuous HRT is hormonal imbalance – ie inadequare or changing dose of progestogen for the dose of oestrogen taken. The hormones administered during HRT, primarily oestrogen and progesterone, need to be in precise balance to prevent unscheduled bleeding. If there is too much or too little of one hormone relative to the other, it can result in breakthrough bleeding. Changes in hormones, such as a change in dose or forgotten dose, can also cause bleeding.
• Endometrial Hyperplasia: This condition involves the overgrowth of the cells that make up the uterine lining. It is often stimulated by an excess of oestrogen without adequate progesterone. If the endometrium becomes too thick, it can lead to bleeding, which is why managing hormone levels is important in continuous HRT. Endometrial hyperplasia can increase the risk of cancer of the endometrium.
• Medication Interaction: The effectiveness of hormone replacement therapy can be compromised by the interaction with other medications. Certain drugs can alter hormone levels or affect how the body responds to hormones in HRT. This disruption can lead to unexpected bleeding and may require adjustments in medication or HRT dosage.
• Other pathology: for example infections, polyps, fibroids, adenomyosis, vaginal atrophy and cancer. These conditions often need to be ruled out before treatment can be given. This is why your doctor may refer you to a gynaecologist for further investigation if you are having unscheduled bleeding.

Understanding these common causes can help individuals on continuous HRT communicate more effectively with their healthcare providers to manage and mitigate bleeding.

When to Consult a Doctor

If you experience occasional spotting or breakthrough bleeding, it might not immediately signal a serious condition. However, that should prompt you to seek medical advice. Speak to a doctor or other healthcare professional without delay if there is:

• Heavy Bleeding: Should the bleeding be as heavy as your usual menstrual flow or necessitate frequent changes of sanitary pads, it is advisable to consult a healthcare provider promptly.
• Prolonged Bleeding: Any bleeding episode that persists for more than a week requires the attention of a medical professional to determine the underlying cause.
• Severe Pain: If the bleeding is accompanied by significant discomfort or pain, immediate medical intervention is necessary.
• Bleeding in between monthly bleeds. If you are having a monthly bleed – for example with sequential HRT – and you bleed inbetween, see a doctor.
• Bleeding after sex.
• Any bleeding on continuous combined ‘no bleed’ HRT should be investigated if it persists beyond 3 months if the HRT has been taken correctly. If there are uncertainties, speak to your doctor.

It is essential to contact a healthcare professional for a proper assessment and management of your symptoms. Ignoring these signs could potentially lead to more serious health issues. Prompt consultation helps in diagnosing the condition early, which is helpful for effective treatment and management.

Diagnostic Approaches

To ascertain the cause of bleeding in patients on continuous HRT, healthcare professionals employ multiple diagnostic strategies. These are important for developing a precise understanding of the underlying issues:

• Medical History: An exhaustive evaluation of the patient’s medical history is essential. This includes a review of any current medications as well as past medical treatments and conditions. Understanding the patient’s health background helps clinicians tailor their diagnostic approach effectively.
• Physical Examination: A comprehensive physical examination is conducted, which includes a pelvic exam. This examination is critical as it allows the healthcare provider to assess any physical signs that might indicate the cause of the bleeding.
• Ultrasound: Imaging tests, particularly a transvaginal ultrasound, play a significant role in the diagnostic process. This type of ultrasound is specifically useful for visualising the thickness of the endometrium, which can indicate abnormalities that might be causing the bleeding.
• Endometrial sampling and hysteroscopy: If the womb lining (endometrium) if thickened or irregular, you may need a sample taking and this can be done at the same time as a hysteroscopy where a fine fibroptic scope is passed through the cervix (neck of the womb) so the cavity of the womb can be visualised. This is usually done by a gynaecologist or specially trained nurse.

Together, these methods provide a robust framework for assessing who needs further investigation or treatment.

Treatment Options for Bleeding

Management of bleeding while on continuous HRT may involve:

• Adjustment of Hormone Dosage: Modifying the type or amount of hormone in the therapy regimen.
• Medication: Using additional medications to control bleeding and protect the endometrium.
• Use of a Mirena (or equivalent) intrauterine system as the progestogen part of HRT for up to 5 years. This is likely to be the most effective way of managing ongoing bleeding on HRT as long as pathology has been excluded.
• Endometrial Ablation: In certain cases, procedures to remove or destroy the lining of the uterus may be recommended.

Always discuss treatment changes with your doctor before making any adjustments.

Preventive Measures and Lifestyle Adjustments

Maintaining a healthy lifestyle can help manage menopause symptoms and potentially reduce the incidence of bleeding on HRT:

• Regular Check-ups: Frequent monitoring by a healthcare provider ensures that any changes in symptoms or side effects are promptly addressed.
• Diet and Exercise: A balanced diet and regular exercise help maintain a healthy weight and reduce menopause symptoms.
