Maternal health experts explain that mild leg swelling, known as physiological fluid retention, affects a large majority of expectant mothers due to increased blood volume and pressure from the growing uterus, and it is generally considered a normal part of a healthy pregnancy. However, specialists warn that prolonged sitting or standing can worsen this swelling and potentially cause blood pressure drops or affect placental health, which is why pregnant women are advised to avoid standing for long periods, keep their legs elevated whenever seated, and limit excessive daily sitting. While normal leg and ankle swelling tends to improve with rest, experts caution that sudden or severe swelling spreading to the face and hands, rapid weight gain, or finding protein in the urine can indicate serious complications like pregnancy-induced hypertension that require immediate medical attention. To safely manage typical discomforts, doctors recommend that pregnant mothers maintain moderate physical activity, reduce their salt and sugar intake, ensure proper rest, and strictly avoid taking over-the-counter medications to reduce swelling without professional medical guidance.
