Hormones, Swelling & Edema: Understanding Women’s Circulation | Part 2

Many women notice that their rings feel tighter, their shoes fit differently, or their legs feel heavier at certain times of the month. These changes are often dismissed as “just hormones.”

In reality, hormones influence far more than reproductive health. They affect fluid retention, blood circulation, vein function, and swelling. This makes hormonal health an important part of overall well-being.

Hormones Influence More Than Reproductive Health

As explored in Part 1, women experience hormonal changes throughout the menstrual cycle, pregnancy, the postpartum period, perimenopause, and menopause. These hormonal fluctuations don't only affect fertility. They also influence blood circulation, fluid retention, energy levels, and the way veins function.

For many women, this can lead to bloating, heavy legs, swollen ankles, swollen feet, and mild edema, particularly during the late luteal phase of the menstrual cycle or during pregnancy.

Why Does Swelling Happen?

Hormonal fluctuations can increase fluid retention while also influencing the function of the veins. During long periods of sitting or standing, gravity allows blood and fluid to collect more easily in the lower limbs, contributing to leg swelling and edema.

Pregnancy places even greater demands on the circulatory system. Rising estrogen and progesterone levels, increased blood volume, and pressure from the growing uterus all contribute to a higher risk of chronic venous insufficiency (CVI), varicose veins, and lower-limb swelling.

Supporting Healthy Circulation

Hormonal changes are a natural part of life, but healthy circulation can still be supported through simple daily habits.

Healthcare professionals commonly recommend:

Regular walking and exercise

Leg elevation

Calf stretches and ankle pumps

Staying well hydrated

Compression therapy when appropriate

Compression garments, including compression socks, compression stockings, and compression sleeves, provide continuous static compression to support blood circulation and venous return during daily activities.

Portable active compression devices deliver dynamic sequential compression that mimics the body's natural circulation, helping improve blood circulation, promote fluid movement, and support recovery.

Looking Ahead

Hormonal changes are a normal part of every woman's life, but symptoms such as swelling, edema, heavy legs, and discomfort should not simply be dismissed as “just hormones.”

Understanding how hormones influence circulation can help women better recognise these changes, support healthy blood flow, and choose the right strategies to maintain long-term venous health and overall well-being.
