Why do I feel nauseous during my period?

Most people experience nausea at some point in their lives. Nausea can arise from a variety of causes. Once this symptom occurs, it is important to actively identify the underlying cause and address it promptly to prevent progression to more serious conditions. So, what causes nausea during menstruation?

What Causes Nausea During Menstruation?

Nausea during menstruation is primarily due to increased secretion of prostaglandins during the menstrual period, which stimulate contraction of gastrointestinal smooth muscle, leading to nausea and vomiting. During menstruation, women’s overall immunity declines, and gastrointestinal function correspondingly weakens. Consuming greasy or cold foods—especially without dietary caution—can further trigger nausea and vomiting. During menstruation, it is advisable to follow a light, easily digestible diet, avoid greasy and cold foods, and drink moderate amounts of warm water or brown sugar water to help alleviate nausea and vomiting. If vomiting is pronounced, vitamin B6 may be taken under a physician’s guidance to relieve symptoms.

During menstruation, abdominal warmth should be maintained to prevent cold exposure and consumption of raw or cold foods, both of which may exacerbate dysmenorrhea. Adequate rest is essential, and strenuous physical activity should be avoided, as it may increase menstrual flow or prolong the menstrual cycle. Sexual intercourse should also be avoided during menstruation to reduce the risk of intrauterine infection. Additionally, many women experience pronounced lower back and knee soreness, fatigue, loss of appetite, and heightened irritability during their periods—symptoms most commonly attributable to hormonal fluctuations.

Adopting healthy dietary habits—including consuming more warming, nourishing foods—can effectively reduce the likelihood of menstrual irregularities. We hope this information proves helpful to you.
