Premenstrual Syndrome (PMS)
Physical and emotional symptoms that occur in the weeks before menstruation
Quick Facts
- Type: Hormonal condition
- Prevalence: 75% of women
- Timing: 1-2 weeks before period
- Duration: Usually resolves with menstruation
Overview
Premenstrual syndrome (PMS) is a collection of physical and emotional symptoms that occur regularly in the luteal phase of the menstrual cycle, typically 1-2 weeks before menstruation begins. These symptoms usually resolve shortly after menstruation starts. PMS affects up to 75% of menstruating women, with severity ranging from mild discomfort to symptoms that significantly impact daily life.
The condition involves a complex interplay of hormonal fluctuations, neurotransmitter changes, and individual sensitivity to these variations. While the exact mechanisms aren't fully understood, the cyclical nature of symptoms and their relationship to the menstrual cycle are key diagnostic features. Symptoms can affect multiple body systems, including the reproductive, nervous, cardiovascular, and gastrointestinal systems.
PMS differs from normal premenstrual changes in its severity and impact on functioning. While many women experience some premenstrual symptoms, PMS is characterized by symptoms that are significant enough to interfere with work, school, social activities, or relationships. Understanding PMS is important because effective treatments are available, and recognition can help women better manage their symptoms and improve their quality of life.

Causes
The exact cause of PMS isn't fully understood, but it appears to result from complex interactions between hormonal fluctuations, neurotransmitter changes, and individual sensitivity factors.
Hormonal Factors

Frequently Asked Questions
PMS is absolutely real and has a biological basis. It involves measurable changes in hormones, neurotransmitters, and brain chemistry. The symptoms are not imaginary or a character flaw. Research has consistently shown that PMS is a legitimate medical condition that can significantly impact quality of life.
PMS can change throughout a woman's reproductive years. Some women find symptoms worsen in their 30s and 40s, particularly as they approach perimenopause. Factors like stress, lifestyle changes, and accumulated life experiences can also influence symptom severity over time.
Birth control pills can help or worsen PMS, depending on the individual and the specific formulation. Pills containing drospirenone (like Yaz) are FDA-approved for PMS treatment. However, some women find their symptoms worsen on hormonal contraceptives. It's important to work with your healthcare provider to find what works best for you.
While men cannot experience PMS directly, they can certainly understand it as a real medical condition and learn to be supportive. Education about the biological basis of PMS and its impact can help partners, family members, and colleagues provide better support and understanding.
Pregnancy temporarily stops PMS since ovulation ceases, but symptoms typically return with the resumption of regular menstrual cycles. Some women find their PMS improves after pregnancy, while others notice it worsens. Breastfeeding can delay the return of symptoms while it suppresses ovulation.
