The duration of perimenopausal bloating varies from woman to woman. Some women may experience bloating for a few days, while others may have it for several weeks or months. In general, perimenopausal bloating tends to be temporary and should resolve on its own once the hormonal fluctuations that are causing it stabilize. However, it is important to note that if the bloating persists for an extended period of time or is accompanied by other symptoms such as pain or discomfort, it may be a sign of an underlying medical condition. If this is the case, it is important to seek medical attention to rule out any serious health issues.
