Heavy or light periods may signal fertility risk

Very heavy or very light periods may be linked to underlying health problems that affect quality of life and can influence fertility, according to medical experts.
Heavy menstrual bleeding is reported to have a major impact on daily life, with around two thirds of affected women seeking medical help. Beyond anaemia, which can cause fatigue, dizziness, pallor and a rapid heartbeat, heavy bleeding can lead to social and practical difficulties such as stained clothing, higher use of menstrual products and work limitations.
Doctors stress that the amount of bleeding itself does not directly affect fertility. Instead, abnormal bleeding can reflect underlying conditions, some of which can make it harder to become pregnant.
Raúl Villasevil, a specialist in obstetrics and gynaecology at San Carlos Clinical Hospital in Madrid, Spain, said: “The most frequent causes of heavy periods are polyps, fibroids, adenomyosis, some malignant tumours, ovulatory and coagulation problems, endometrial disorders, and certain medications.”
Very light periods can also signal problems, including uterine malformations, intrauterine adhesions, where scar tissue forms inside the womb, and anatomical abnormalities of the vagina. They may also point to ovulatory and hormonal disorders such as hyperprolactinaemia, which involves excess production of the hormone prolactin, or polycystic ovary syndrome. Once confirmed, these conditions can lead to symptoms including infertility.
To identify the cause of abnormal bleeding, Villasevil said doctors begin with a detailed personal and gynaecological history, followed by a physical examination and usually an ultrasound to assess the uterus and ovaries. Blood tests are also used to check for anaemia, coagulation status and hormonal function.
“This basic evaluation is often sufficient to establish the cause of the bleeding abnormality and to propose solutions. If this basic workup does not identify the cause, additional tests such as hysteroscopy or magnetic resonance imaging can be performed,” he added.
Hysteroscopy involves inserting a small camera into the womb to examine it from the inside.
In most cases, the cause of menstrual abnormalities can be identified and treated. A range of treatments allow a personalised approach for each woman, taking into account whether she wishes to have children, her age and her individual needs at different stages of life.

Menopause
Non-hormonal menopause pill approved for NHS use

A new daily menopause pill approved for NHS use could bring relief to women with debilitating hot flushes and night sweats.
Around 500,000 women are expected to be eligible for the treatment, which experts say could help those unable to take hormone replacement therapy, or HRT.
The drug, fezolinetant, also known as Veoza, is a daily non-hormonal tablet designed to target the brain signals that trigger some of the most disruptive menopause symptoms.
In final draft guidance published today, the National Institute for Health and Care Excellence recommended the 45mg tablet for women experiencing moderate to severe hot flushes and night sweats.
More than two million women in the UK are thought to suffer these symptoms during menopause, often beginning during the earlier stage known as perimenopause.
For many, the effects are severe, disrupting sleep, affecting concentration and straining relationships. In some cases women are even forced to cut back on work.
An estimated 60,000 women in the UK are currently out of work or on long-term sick leave due to severe menopause symptoms, costing the economy roughly £1.5bn a year.
Research also suggests one in 10 women has left the workforce entirely because of a lack of support.
