Premenstrual syndrome (PMS) describes physical, emotional, or behavioral symptoms that occur in a repeating pattern before a menstrual period and improve after the period begins. Symptoms can be mild for some people and disruptive for others.
Common PMS Symptoms
Symptoms vary, but may include bloating, breast tenderness, headaches, cramps, fatigue, food cravings, sleep changes, irritability, anxiety, sadness, difficulty concentrating, or mood changes.
These symptoms are not specific to PMS. Thyroid disease, depression, anxiety disorders, endometriosis, and other conditions can cause similar symptoms, so persistent or severe problems deserve medical evaluation.
How Is PMS Diagnosed?
There is no single blood test that confirms PMS. ACOG guidance emphasizes the timing and pattern of symptoms. Tracking symptoms across at least two menstrual cycles can help show whether they reliably occur before the period and improve afterward.
If symptoms are severe enough to cause major problems at work, school, relationships, or daily life—especially severe depression, anxiety, anger, or mood changes—a clinician may consider premenstrual dysphoric disorder (PMDD), a more severe premenstrual disorder.
What Can Help PMS?
Treatment should match the symptoms and how much they affect daily life. ACOG supports a multimodal approach, which may include lifestyle measures, psychological support, and medicines when appropriate.
- Regular physical activity: may help mood, fatigue, and general wellbeing.
- Sleep and stress management: consistent sleep, relaxation strategies, counseling, or cognitive behavioral approaches may be useful for some people.
- Pain relief: nonprescription pain medicines may help cramps or headaches when they are safe for the individual. Follow the label and ask a pharmacist or clinician if you have kidney disease, stomach ulcers, take blood thinners, or have other medical concerns.
- Prescription treatment: SSRIs and some hormonal contraceptives are evidence-based options for selected patients. The best choice depends on symptoms, medical history, pregnancy plans, and personal preference.
What About Vitamins and Herbal Supplements?
Evidence for supplements and herbal products is mixed, and products can interact with medicines. Do not assume a supplement is safe simply because it is “natural,” and avoid high-dose self-treatment based on online claims. A clinician or pharmacist can help review a specific product.
When to Seek Help
See a healthcare professional if symptoms are worsening, interfere with normal activities, do not follow a clear menstrual pattern, or are difficult to manage. Seek urgent help for suicidal thoughts, thoughts of self-harm, severe depression, or any mental-health emergency.
Bottom Line
PMS is diagnosed mainly by its repeating relationship to the menstrual cycle. Tracking symptoms can help distinguish PMS from other conditions. Effective care may combine lifestyle support, psychological treatment, and medicines rather than relying on one “natural cure.”
