Yes, stopping ovulation with leuprolide acetate significantly improved bowel symptoms related to the menstrual cycle. Adding tibolone (a hormone) did not improve bowel symptoms further but did improve quality of life more than leuprolide alone.

Review, 2003

How do menstrual cycle hormones affect the brain and cause mood disorders like PMDD?

A hormone called allopregnanolone acts on brain receptors. Changes in this hormone during the cycle may cause mood and behavioral symptoms in up to 20% of people through three mechanisms: direct effects, building tolerance, and withdrawal effects.

Randomised trial, 2003

Yes, SSRIs are effective first-line treatments for PMDD. Both continuous dosing and intermittent dosing during the luteal phase lead to rapid improvement in symptoms and functioning.

Review, 2001

What causes PMS and PMDD, and how are they treated?

PMS is caused by abnormal responses to normal hormone changes during the menstrual cycle. Treatment includes lifestyle changes like diet and exercise, and medications. SSRIs are the first-line treatment for PMDD, and calcium supplements may help.

Randomised trial, 2001

Yes. SSRIs work significantly better than placebo and faster than when used for depression or anxiety. Intermittent dosing (taking medication only before the period) may work even better than daily dosing.

Randomised trial, 1998

Is intermittent citalopram during the luteal phase more effective than continuous dosing?

Yes, taking citalopram only during the luteal phase was more effective than placebo and appeared more effective than continuous or semi-continuous dosing, with mild side effects.

Randomised trial, 1997

Between 5% and 8% of women have moderate-to-severe symptoms that cause significant problems with work, relationships, and daily life. These are called PMS or PMDD. PMDD is the most severe form.

Cohort study, 2026

Does a birth control pill with estetrol and drospirenone help PMS?

Yes. Over 3 months, this combination birth control significantly improved PMS symptoms and hormone levels. Non-hormonal therapy also helped but had smaller effects.

Randomised trial, 2025

Does escitalopram reduce aggressive behavior in women with premenstrual anger and irritability?

Escitalopram reduced self-reported irritability and anger, and decreased aggressive behavior on one lab test but only in some women whose anger followed a specific pattern. We can be moderately confident in this finding.

Survey study, 2025

What psychological and personal factors predict which university students will develop premenstrual syndrome?

High anger, low social support, childhood trauma, high stress, negative attitudes toward menstruation, and poor satisfaction with gender roles all predict PMS. However, results are limited to university students in one country.

Yes. Women with recent suicidal thoughts reported significantly more severe ideation during the perimenstrual phase (around their period) compared to other cycle phases. The cycle explained 25% of the change in suicidal thoughts.

Randomised trial, 2023

Does alternate-day modified fasting improve PMS symptoms and quality of life in overweight or obese women?

Yes, alternate-day modified fasting improved mood lability, expressed anger, and mental health more than daily calorie restriction. These improvements were statistically significant but dropout was high.

Randomised trial, 2023

Does gamma-tocopherol (a form of vitamin E) reduce premenstrual syndrome symptoms?

Yes. Gamma-tocopherol significantly reduced fatigue and anger, and also reduced leg swelling. Because this was a well-designed controlled trial where each woman tried both treatments, we can be fairly confident about these effects.

Randomised trial, 2023

Yes. Women with PMS showed different brain wave patterns and lower stress hormone levels. These differences were moderately linked to how severe their PMS was.

Survey study, 2023

Which PMDD symptoms cause the most impairment and do they all belong in one condition?

Irritability is by far the most impairing PMDD symptom, affecting 77% of women with premenstrual symptoms. However, many of the symptoms listed in PMDD criteria appear unrelated to mood symptoms and don't seem clinically important on their own.

Survey study, 2022

Is premenstrual syndrome related to aggression in adolescent girls?

Yes. Aggression tendencies increased as PMS severity increased, and girls who noticed increased anger before their period had higher PMS intensity overall.

Randomised trial, 2022

Yes, it helped several psychological symptoms like mood, anxiety, and irritability compared to placebo. The study was small, so we need larger trials to be sure.

Survey study, 2022

What factors are linked to PMS in teenage girls?

Most teenage girls have some PMS. Backache and breast tenderness are common physical symptoms. Irritability, anxiety, and mood swings are common emotional symptoms. Eating sweets, education level, and family circumstances are linked to PMS, but body weight is not.

Cohort study, 2022

What are PMS and PMDD and how should they be diagnosed and treated?
