Know Your Cycle.
Own Your Health.

Menstrual health is a cornerstone of overall wellbeing for women and girls — yet it remains one of the most underserved areas of healthcare in South Africa. Painful, heavy or irregular periods are often normalised or dismissed, while conditions like endometriosis can take an average of seven to ten years to diagnose. HealthLab’s Menstrual Health Hub exists to change that — providing evidence-based, locally relevant guidance that helps South African women understand their cycles, recognise when something is wrong, and access the right care.

Period Basics: Understanding Your Cycle

A healthy menstrual cycle typically ranges from 21 to 35 days, with bleeding lasting 3 to 7 days. The average blood loss per cycle is 30 to 80ml — roughly 4 to 12 teaspoons. What’s normal for one woman may differ considerably from another, which is why understanding your own cycle pattern is more important than comparing yourself to averages. The menstrual cycle is driven by a finely orchestrated hormonal interplay between the brain (hypothalamus and pituitary), the ovaries and the uterus — involving oestrogen, progesterone, FSH and LH at different phases.

Menstrual Issues & Disorders

Menstrual disorders encompass a wide range of conditions that disrupt the normal pattern of periods. Dysmenorrhoea (painful periods) affects up to 90% of menstruating women at some point — primary dysmenorrhoea is caused by prostaglandins triggering uterine contractions, while secondary dysmenorrhoea is caused by an underlying condition such as endometriosis or fibroids. Menorrhagia (heavy periods) is defined as blood loss exceeding 80ml per cycle and can cause iron deficiency anaemia. Irregular cycles (oligomenorrhoea) and absent periods (amenorrhoea) each have distinct diagnostic pathways and causes — from PCOS and thyroid disorders to hypothalamic amenorrhoea from under-eating or over-exercising.

Endometriosis — tissue similar to the uterine lining growing outside the uterus — affects approximately 1 in 10 women globally and remains severely underdiagnosed in South Africa. Uterine fibroids affect up to 70% of women by age 50 and are the leading cause of heavy periods and hysterectomy. Adenomyosis, where the uterine lining grows into the muscle wall, causes severe cramping and heavy bleeding. All of these conditions have effective treatment options that can dramatically improve quality of life when diagnosed appropriately.

PMS & PMDD: When Hormones Affect Your Mood

Premenstrual Syndrome (PMS) affects up to 75% of menstruating women — causing physical symptoms (bloating, breast tenderness, headaches) and emotional symptoms (irritability, anxiety, low mood) in the 1 to 2 weeks before menstruation. For 3 to 8% of women, symptoms are severe enough to qualify as Premenstrual Dysphoric Disorder (PMDD) — a recognised psychiatric and gynaecological condition causing debilitating mood disturbances that significantly impair work, relationships and daily life. Both conditions are driven by sensitivity to the normal hormonal changes of the luteal phase and respond well to evidence-based interventions.

Finding Specialist Care in South Africa

Accessing quality menstrual health care in South Africa requires knowing where to look. Gynaecologists are typically the first point of referral for most menstrual concerns. Endocrinologists manage hormonal drivers of cycle disruption. Pelvic physiotherapists play a critical role in managing endometriosis-related pain and pelvic floor dysfunction. HealthLab’s professional directory connects South African women with HPCSA-registered specialists across all nine provinces — helping you find the right expert for your specific needs.
