What causes painful periods and what actually helps?

What the AIs say

Painful periods (dysmenorrhea) are extremely common and usually come down to one of two things: either your uterus is producing high levels of prostaglandins (hormone-like chemicals that cause strong contractions — this is called *primary* dysmenorrhea), or there's an underlying condition like endometriosis, fibroids, or adenomyosis driving the pain (*secondary* dysmenorrhea). Most women experience the primary type, especially in their teens and twenties.

Painful periods (dysmenorrhea) are extremely common and usually come down to one of two things: either your uterus is producing high levels of prostaglandins (hormone-like chemicals that cause strong contractions — this is called *primary* dysmenorrhea), or there's an underlying condition like endometriosis, fibroids, or adenomyosis driving the pain (*secondary* dysmenorrhea). Most women experience the primary type, especially in their teens and twenties. **Here's what genuinely helps, starting with the most effective:** - **NSAIDs first** (ibuprofen, naproxen): These are the most evidence-backed option. They work by actually reducing prostaglandin production — not just masking pain. Crucially, start taking them *before* your cramps peak, ideally at the first sign of your period or even a day before if you're predictable. This matters more than most people realize. - **Heat therapy**: A heating pad or hot bath is legitimately effective, not just comforting. Use it freely. - **Regular exercise**: Aerobic activity between periods (not just during) has good evidence for reducing menstrual pain over time. - **Hormonal birth control**: Pills, patches, or hormonal IUDs can significantly reduce or eliminate cramps for many women — worth discussing with a doctor if other methods aren't enough. - **Magnesium supplements**: Modest but real evidence supports this; low risk to try. **See a doctor if:** your pain is severe, worsening over time, not responding to NSAIDs, interfering with daily life, or if your pain pattern has recently changed. These are red flags for secondary dysmenorrhea, which requires diagnosis and targeted treatment — not just pain management. ---

Where the AIs Agree

  • All responses agree that prostaglandins causing uterine contractions are the primary driver of typical period pain (primary dysmenorrhea).
  • All agree that NSAIDs (ibuprofen, naproxen) are the most effective first-line treatment, and that timing — taking them early — improves their effectiveness.
  • All responses identify the same underlying conditions (endometriosis, fibroids, adenomyosis, PID) as causes of secondary dysmenorrhea requiring medical evaluation.
  • Heat therapy and exercise are consistently endorsed across all responses as genuinely helpful, evidence-backed options.
  • All responses agree hormonal birth control is a valid medical option for reducing pain, with the caveat that it's not right for everyone.
  • All responses flag the same warning signs for seeing a doctor: severe, worsening, or life-disrupting pain.

Where the AIs Disagree

  • **Dietary changes**: Claude rates dietary changes as having "limited evidence," while Grok gives them moderate consideration (especially omega-3s for inflammation). ChatGPT mentions reducing caffeine/salt more casually. There's genuine uncertainty here — the evidence is mixed.
  • **Magnesium supplements**: Claude specifically calls out magnesium as having moderate evidence, while other responses don't mention it. This is a meaningful omission by some models.
  • **Acupuncture and alternative therapies**: Grok and Claude both note "mixed" or inconclusive evidence and frame them as low-risk rather than recommended. ChatGPT includes them without that important qualifier, which slightly overstates confidence.
  • **Confidence levels on statistics**: Grok provides specific numbers (e.g., "NSAIDs relieve symptoms in 70–80% of people"; "secondary dysmenorrhea in 10–25% of cases") that the other models don't. These figures are plausible but should be taken as approximate, not definitive.
  • **Response 2 (Gemini)** was cut off and incomplete, so it couldn't be fully evaluated — its perspective may be underrepresented in this synthesis.
