This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I am a 38-year-old woman experiencing severe nausea and migraines just before my periods. Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I read your query and can understand your concern.

It seems that you may be experiencing premenstrual syndrome (PMS), which refers to a set of physical, emotional, and behavioral symptoms that occur in the days or weeks before a woman's menstrual period or menstrual migraines, both of which are common in women of your age group.

Intense nausea (vomiting) and migraines (intense headaches) just before your period are likely due to hormonal fluctuations, particularly a drop in estrogen leading up to menstruation (women's regular hormonal cycle).

Possible causes:

  1. Menstrual migraines: These occur due to a drop in estrogen before your period and can cause severe headaches, nausea, vomiting, and sensitivity to light or sound.

  2. PMS or PMDD is a premenstrual dysphoric disorder: Some women experience nausea, headaches, mood swings, and fatigue as part of PMS or its more severe form PMDD.

  3. Low blood sugar or dehydration: Hormonal changes can impact blood sugar levels and hydration, leading to nausea and migraines.

  4. Magnesium deficiency: Low magnesium levels may trigger migraines, especially before your period.

  5. Gut sensitivity or acid reflux: Hormonal fluctuations can worsen acid reflux or other digestive issues, contributing to nausea.

What you can try:

Lifestyle and diet adjustments:

  1. Stay hydrated and eat small, frequent meals to keep blood sugar stable.

  2. Increase magnesium-rich foods like nuts, seeds, and spinach, or consider taking them as a supplement.

  3. Reduce caffeine, alcohol, and processed foods, which can trigger migraines.

Home remedies:

  1. Apply a cold compress to your head for migraine relief.

  2. Sip ginger tea to help ease nausea.

  3. Rest in a dark, quiet room during a migraine episode.

Medications if needed:

  1. Over-the-counter pain relievers like Ibuprofen or Naproxen can help when taken before migraines begin.

  2. If migraines are severe, your doctor may recommend triptans such as sumatriptan or hormonal therapy.

  3. Vitamin B6 supplements may help with PMS-related nausea.

When to see a doctor:

  1. If your migraines or nausea are severe, disabling, or worsening over time.

  2. If you experience vision changes, weakness, or confusion, it could indicate a more serious migraine.

  3. If nausea is persistent and unrelated to your menstrual cycle.

I hope this helps.

Please revert in case of further queries.

Thank you.
