Premenstrual water retention, also known as premenstrual edema, is a common symptom experienced by many women during the days leading up to their menstrual period. This condition is due to hormonal fluctuations in the body that can cause fluid to accumulate in the tissues. Other synonyms for premenstrual water retention include premenstrual bloating, premenstrual swelling, premenstrual fluid retention, and premenstrual puffiness. Symptoms of premenstrual water retention can include weight gain, puffiness in the face, hands, or feet, and discomfort or bloating in the abdominal area. Simple lifestyle changes such as avoiding salt and caffeine, staying hydrated, and exercising regularly can help alleviate symptoms.
