Common Menstrual Health Conditions
What every woman should know.
Menstrual health is a vital indicator of overall wellbeing - and yet many women live with symptoms that are dismissed as “normal” or simply something to put up with.
Painful, heavy, irregular, or absent periods are not just inconvenient; they can be signs of underlying medical conditions that deserve proper assessment and treatment.
At Clinic51, we take all menstrual health concerns very seriously – and regularly see women who have lived for years with symptoms that have been minimised or misunderstood. Yet early recognition and appropriate management can make a significant difference to both a woman’s quality of life and her long-term health.
Here is an overview of some of the most common menstrual health conditions we see, their symptoms, and when to seek medical advice.
Uterine Fibroids
Uterine fibroids are benign (non-cancerous) growths of the muscle wall of the uterus. They are extremely common, particularly in women in their 30s and 40s, and are more prevalent in certain ethnic groups.
Fibroids vary widely in size and location, which is why symptoms differ from person to person. Some women have fibroids and no symptoms at all, while others experience:
Heavy or prolonged periods
Pelvic pain or pressure
Abdominal bloating
Pain during sex
Urinary frequency or constipation
Heavy bleeding from fibroids can lead to iron-deficiency anaemia, causing fatigue and breathlessness. They can also lead to issues conceiving, or recurrent miscarriage. In more severe cases impairment of kidney function can result from compression of other structures. Management depends on symptoms, fibroid size, future fertility wishes, and proximity to menopause. Options range from monitoring and medication to procedural or surgical treatments.
Endometriosis
Endometriosis occurs when tissue similar to the lining of the uterus grows outside the womb, commonly on the ovaries, pelvic lining, or bowel. It is a chronic condition that can significantly affect physical, emotional, and reproductive health.
Typical symptoms include:
Severe period pain that interferes with daily life
Pain during or after sex
Pelvic pain outside of periods
Pain with bowel movements or urination (especially during periods)
Difficulty conceiving
Endometriosis pain is often dismissed as “bad periods,” leading to delays in diagnosis that can last years. While there is no single cure, early diagnosis allows for symptom control, minimisation of long term damage, fertility planning, and improved quality of life through tailored medical and surgical approaches.
Adenomyosis
Adenomyosis is a condition where tissue similar to the uterine lining grows into the muscle wall of the uterus. It most commonly affects women in their late 30s and 40s, particularly those who have been pregnant, although it can occur at any age.
Symptoms may include:
Very heavy or prolonged periods
Severe cramping or pelvic pain
Pain during sex
A feeling of pelvic heaviness
Adenomyosis can be challenging to diagnose and is often confused with fibroids or endometriosis clinically, but can be identified by ultrasound scan or MRI. Treatment focuses on symptom relief and may include suppression of the disease using hormonal therapies or, in more severe cases, surgery. Individualised assessment is essential.
Polycystic Ovarian Syndrome (PCOS)
PCOS is one of the most common hormonal conditions affecting women of reproductive age. It is characterised by a combination of hormonal imbalance and disrupted ovulation.
Symptoms can include:
Irregular or absent periods
Acne or oily skin
Excess dark, coarse facial or body hair
Thinning scalp hair
Weight gain or difficulty losing weight
Fertility challenges
PCOS is also associated with insulin resistance, increased risk of type 2 diabetes, and long-term cardiovascular risk. Importantly, not all women with PCOS are overweight, and symptoms can change over time.
Management goes beyond regulating periods—it involves addressing metabolic health, hormone balance, fertility goals, and long-term wellbeing.

Hypothalamic Amenorrhoea
Hypothalamic amenorrhoea occurs when periods stop because the brain reduces signals to the ovaries. This is usually a response to physical or psychological stress, rather than a problem with the ovaries themselves.
Common triggers include:
Significant weight loss or low body weight
Excessive exercise
Chronic stress or anxiety
Restrictive eating patterns
Women with hypothalamic amenorrhoea may also experience hair loss, headaches, difficulty sleeping and low energy. They may, however, feel otherwise well, which can delay diagnosis. However, low oestrogen levels can affect bone density, cardiovascular health, and fertility.
Secondary amenorrhoea (when periods suddenly stop for 3 months or more) can be caused by other hormonal disturbances such as thyroid or prolactin. It is really vital that these are excluded, so diagnosis often focuses on investigating whether other hormonal disruption exists.
Treatment focuses on addressing the underlying cause—often involving nutritional support, stress reduction, and adjustments to exercise—rather than simply inducing periods with hormones.
Premenstrual Syndrome (PMS) and Premenstrual Dysphoric Disorder (PMDD)
PMS refers to a group of physical and psychological symptoms that occur in the luteal phase of the menstrual cycle (after ovulation and before a period). Symptoms usually resolve once bleeding begins.
Common PMS symptoms include:
Mood changes or irritability
Bloating
Breast tenderness
Fatigue
Headaches
PMDD is a more severe form, with symptoms that can be debilitating and significantly affect relationships, work, and mental health. Women with PMDD may experience severe low mood, anxiety, rage, or hopelessness each month.
Both PMS and PMDD are recognised medical conditions, not character flaws. Effective treatments are available, ranging from lifestyle strategies and hormonal options to specific medications that target the brain’s response to hormonal changes.
Premature Ovarian Insufficiency (POI)
POI occurs when the ovaries stop functioning normally before the age of 40. This leads to reduced oestrogen levels and irregular or absent periods. In the majority of cases it is spontaneous, with an unknown cause - but can be caused by genetic factors, autoimmune conditions or as the result of medical or surgical treatment.
Symptoms may include:
Missed or irregular periods
Hot flushes or night sweats
Vaginal dryness
Mood changes
Fertility difficulties
POI is not the same as early menopause, which occurs between the ages of 40-45. However, the health implications are similar but magnified, due to more protracted duration of oestrogen withdrawal, which leads to an increased risks to bone and heart health.
Early diagnosis is crucial. Hormone replacement therapy (HRT) is usually recommended until at least the average age of natural menopause, unless there is a medical reason not to use it.
Pelvic Inflammatory Disease (PID)
PID is an infection of the female reproductive organs, often caused by untreated sexually transmitted infections, though not always. It can affect the uterus, fallopian tubes, and ovaries.
Symptoms may include:
Lower abdominal or pelvic pain
Pain during sex
Abnormal vaginal discharge
Irregular bleeding
Fever or feeling unwell
Some women have very mild symptoms or none at all, yet the long-term consequences can be serious, including chronic pelvic pain, ectopic pregnancy, and infertility.
Prompt diagnosis and treatment with antibiotics are essential to reduce the risk of long-term complications.
When to seek medical advice
Periods should not routinely disrupt daily life. Medical advice should be sought any time if periods are:
Extremely painful
Very heavy or prolonged
Absent or highly irregular
Associated with significant mood changes
Accompanied by pelvic pain outside of menstruation
Early assessment allows for accurate diagnosis, reassurance where appropriate, and timely treatment where needed.
A personalised, doctor-led approach
Menstrual health is complex, and no two women experience it in the same way. At Clinic51, care is led by doctors, including our consultant obstetrician & gynaecologist, Dr Leah Deutsch, with a focus on listening, investigating thoroughly, and creating personalised treatment plans.
Whether symptoms are new, long-standing, or changing over time, they deserve proper attention. Understanding menstrual health is not about labelling women with diagnoses - it is about empowering them with clarity, options, and support.
If something about your cycle does not feel right, it is worth exploring. Your periods are telling you something, and they deserve to be heard….
