Periods Stopped: Causes, Diagnosis and Treatment

Stopped periods can have hormonal, structural, genetic or life-stage causes, so assessment starts by confirming the pattern and excluding pregnancy.

Periods stopped means menstrual bleeding has not arrived when expected or has ceased after previously occurring. Some people have no other symptoms. Others notice hot flushes, vaginal dryness, acne, increased facial hair, nipple discharge, headaches, vision changes, pelvic pain or symptoms linked to eating, exercise, stress or weight change. The age when periods stopped and whether they had started before are useful details.

Take a pregnancy test if pregnancy is possible. Seek urgent help for severe pelvic pain, fainting, heavy bleeding after a missed period, or a severe headache with vision changes. Arrange prompt medical review for nipple discharge that is not related to breastfeeding, new neurological symptoms, or periods stopping with marked pelvic pain.

The causes below are alphabetical, not a likelihood ranking. Asherman syndrome involves scar tissue inside the uterus that can reduce or block menstrual flow. Hyperprolactinaemia is raised prolactin, which can interfere with reproductive hormones. Hypothalamic amenorrhoea occurs when the brain reduces reproductive hormone signalling, sometimes alongside under-fuelling, intense exercise or stress. An imperforate hymen can obstruct flow from the vagina and is usually recognised around puberty. Menopause is the life stage when ovarian hormone activity declines and periods end. Polycystic ovary syndrome can disrupt ovulation. Premature ovarian insufficiency affects ovarian function earlier than expected. Turner syndrome is a chromosomal condition that can affect ovarian development.

Assessment covers menstrual history, pregnancy possibility, medicines, contraception, nutrition, exercise, stress, symptoms of menopause and family history. A clinician may perform an examination and arrange pregnancy testing, hormone blood tests, thyroid testing or pelvic ultrasound. If periods never began, the examination and imaging may focus on the reproductive tract and pubertal development. The tests selected depend on your age, history and symptoms.

Treatment may involve restoring adequate nutrition and reducing excessive training when low energy availability is contributing. Hormone treatment can be considered when ovarian hormone levels are low or when cycle control is needed. Polycystic ovary syndrome is managed according to symptoms and pregnancy plans. A structural blockage or uterine scarring may need a procedure. If high prolactin or a thyroid problem is found, treating that underlying issue may help reproductive hormone signalling. Menopause-related symptoms can be addressed with personalised options.

Some causes cannot be prevented, but regular meals, adequate energy for exercise, sensible training recovery and support for significant stress can protect menstrual function. Do not stop prescribed contraception or other medicines without advice. Track bleeding, symptoms, exercise, dietary changes and medicines; this record can reveal a pattern and helps a clinician decide how quickly to investigate.

Stopped periods may be accompanied by hot flushes, sleep changes, vaginal dryness, acne, increased hair growth, hair thinning, breast discharge, headaches, vision changes or pelvic pain. These details help distinguish changes in ovulation, ovarian hormone activity, prolactin signalling and structural causes.

A review may confirm pregnancy, identify a hormone-related change, show a structural issue or point to a genetic or ovarian condition. If initial tests are reassuring, follow-up can monitor cycle recovery, bone health, fertility goals and any ongoing symptoms.
