Does red wine cause menstruation to come on?

Red wine does not directly cause menstruation, but alcohol consumption can influence hormonal balance and potentially affect the menstrual cycle. Some women may experience changes in their cycle due to alcohol, including irregularities or changes in flow, but these effects can vary widely among individuals. Additionally, excessive alcohol consumption can lead to health issues that may disrupt normal menstrual function. It's important to consult with a healthcare professional for personalized advice regarding menstrual health.
