Nausea during your period is commonly caused by hormonal changes, particularly the increase in prostaglandins. These hormones help the uterus contract to shed its lining but can also cause nausea, vomiting, and gastrointestinal disturbances. Painful menstrual cramps (dysmenorrhea), which result from strong uterine contractions triggered by prostaglandins, can also lead to nausea. In some cases, stress, sensitivity to odors, certain foods, or underlying conditions like endometriosis can worsen nausea during menstruation.

Causes of Nausea During Periods

• Hormonal fluctuations, mainly from prostaglandins, cause uterine contractions and nausea.
• Dysmenorrhea or severe menstrual cramps raise prostaglandin levels and cause pain and nausea.
• Stress and anxiety increase nausea by affecting digestion.
• Sensitivity to strong smells or certain foods can trigger queasiness.
• Some conditions like endometriosis or pelvic inflammatory disease may cause more severe symptoms.

Symptoms and Management

Nausea often peaks in the early days of menstruation and may accompany cramps, headaches, diarrhea, and fatigue. It usually resolves within a few days. Managing nausea can include eating light foods, staying hydrated, using over- the-counter pain relievers, and applying heat to relieve cramps.

If nausea is severe, persistent, or accompanied by other worrying symptoms, medical advice should be sought to rule out conditions like endometriosis or infections.

In summary, nausea on your period is primarily due to hormone-induced uterine contractions and cramps, but lifestyle, stress, and medical factors can also play a role.
