Period pain is one of the most common health complaints among women of reproductive age, yet it is also one of the most dismissed. Cramping, lower back pain, nausea, and fatigue during your period can range from mildly uncomfortable to genuinely debilitating. Understanding what causes period pain and what actually works to relieve it can make a significant difference to your quality of life each month.
What Causes Period Pain?
Period pain (medically called dysmenorrhoea) is caused by prostaglandins, hormone-like chemicals the uterus produces to trigger contractions that help shed the uterine lining. Higher levels of prostaglandins cause more intense contractions, which reduce blood flow to the uterus and cause the cramping sensation.
There are two types:
- Primary dysmenorrhoea: Period pain with no underlying medical cause. Common in the first few days of the period, especially in younger women. Often improves with age or after having children.
- Secondary dysmenorrhoea: Period pain caused by a medical condition such as endometriosis, fibroids, adenomyosis, or pelvic inflammatory disease. This type tends to be more severe and may worsen over time.
Evidence-Based Ways to Relieve Period Pain
Anti-Inflammatory Pain Relief
Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen are the most effective over-the-counter treatment for period pain. They work by reducing prostaglandin production directly, targeting the root cause rather than just masking the pain.
- Take ibuprofen (200 to 400mg) or naproxen (220mg) at the first sign of cramping
- For best results, start taking NSAIDs the day before your period is due
- Take with food to reduce stomach irritation
- If you have a history of stomach ulcers or kidney problems, check with your GP before taking NSAIDs regularly
Heat Therapy
Applying heat to the lower abdomen is one of the most effective and immediate ways to ease period cramps. Research shows that a heat patch at around 40°C applied continuously over several hours can be as effective as ibuprofen for pain relief.
- Heat packs, hot water bottles, or adhesive heat patches all work well
- A warm bath can provide whole-body relief and reduce back pain
- Apply heat to the lower back too if you experience back cramping
Movement and Exercise
It might be the last thing you feel like doing, but gentle movement genuinely helps. Exercise releases endorphins and improves blood circulation to the pelvic region, reducing the intensity of cramping.
- A 20 to 30 minute walk, yoga session, or light swim can reduce pain scores significantly
- Yoga poses such as child’s pose, supine twist, and cat-cow are particularly helpful
- High-intensity exercise is not necessary; gentle movement is enough to see benefit
Dietary Changes
Certain dietary approaches have some evidence behind them for reducing period pain severity over time:
- Increase omega-3 fatty acids: Oily fish (salmon, sardines, mackerel), walnuts, and flaxseed have anti-inflammatory effects that may reduce prostaglandin activity
- Reduce processed foods and sugar: High-sugar and high-fat diets appear to worsen inflammation and period pain
- Reduce caffeine and alcohol: Both can worsen bloating and discomfort during your period
- Stay hydrated: Dehydration worsens cramping and fatigue
Hormonal Contraception
For women whose period pain is significantly impacting their life, hormonal contraception can be an effective management option. Options include the combined oral contraceptive pill, the progesterone-only pill, the hormonal IUD (Mirena), or the implant. All reduce menstrual flow and cramping in most users.
This is a conversation to have with your GP, who can discuss which option suits your health history and life circumstances.
TENS Machines
Transcutaneous electrical nerve stimulation (TENS) devices can be effective for some women. They work by sending low-level electrical pulses that interrupt pain signals before they reach the brain. Portable TENS units designed for period pain are available at pharmacies without a prescription.
When Is Period Pain a Sign of Something More Serious?
Pain that is severe, worsening over time, or affecting your ability to function at work or socially deserves medical attention. These patterns may indicate an underlying condition such as endometriosis or adenomyosis that benefits from diagnosis and specific treatment.
Speak with your GP if:
- Your period pain has become worse over recent months or years
- Over-the-counter pain relief no longer provides adequate control
- You have pain outside of your period (mid-cycle, during sex, or when opening your bowels)
- You have heavy bleeding (soaking through a pad or tampon every hour for several consecutive hours)
- Period pain is causing you to miss work, school, or social commitments regularly
Track Your Cycle and Symptoms with NORMA
NORMA includes a free period tracker that is available on the free plan, with no ads and no paywalls. Tracking your cycle length, flow, and associated symptoms over several months gives you genuinely useful data to bring to your GP. Instead of trying to remember whether your pain has been getting worse, you can show your doctor a symptom pattern over time.
You can also use NORMA to get a clearer picture of whether the symptoms you are experiencing fall within the typical range, or whether they suggest a conversation with your GP is overdue. Tracking is free. The insights are immediate.
Frequently Asked Questions
Is it normal to have severe period pain?
Mild to moderate cramping is normal. Severe pain that regularly interferes with your daily life is not something you simply have to tolerate. It may indicate an underlying condition. See your GP if your pain is difficult to manage or is getting worse over time.
What is the fastest way to relieve period cramps?
Taking an NSAID (such as ibuprofen) plus applying a heat pack to the lower abdomen together produces the fastest pain relief for most women. Start the NSAID before the pain peaks if possible.
Does period pain get better with age?
Primary dysmenorrhoea (no underlying cause) often improves after the mid-twenties or after having children. Secondary dysmenorrhoea caused by conditions like endometriosis tends to worsen over time without treatment.
