Common Symptoms
Women with idiopathic edema often report swelling in the legs, hands, and face. This swelling is typically periodic and may be accompanied by abdominal bloating. Symptoms can vary widely in severity, from mild discomfort to significant weight gain and swelling.
When Symptoms Appear
Idiopathic edema tends to occur in women between puberty and menopause, but it can persist after menopause. Symptoms are often worse during the day when standing, due to gravity's effect on fluid retention. Nocturia, or frequent urination at night, is also a common symptom due to fluid shifting when lying down.

Weight Fluctuations
Weight gain in idiopathic edema can be quite dramatic, with fluctuations of up to 5 kg in severe cases. This gain is often more noticeable in the evening after a day of standing. However, the perceived severity of symptoms can sometimes be greater than what is physically observable.
