Water Retention Before Your Period
By Dr (TCM) Attilio D'Alberto | Traditional Chinese Medicine Practitioner, Wokingham
Premenstrual water retention — swollen, puffy fingers, a bloated abdomen, breast heaviness, and a sense of fullness that disappears as soon as the period starts — is one of the most common cycle-related complaints. It is driven by the hormonal changes of the late luteal phase and reflects a disruption in fluid metabolism that traditional Chinese medicine understands in terms of spleen qi deficiency and liver qi stagnation affecting fluid transformation.
Why Does Water Retention Occur Premenstrually?
The hormonal shifts of the late luteal phase — rising progesterone, falling oestrogen, and increased aldosterone activity — cause the kidneys to retain sodium and water. Oestrogen also increases capillary permeability, allowing fluid to move from the blood vessels into the surrounding tissues. In women with more pronounced hormonal fluctuations — as seen in oestrogen dominance — these effects are amplified. The fluid typically redistributes once menstruation begins and progesterone falls sharply.
TCM Patterns
Spleen qi deficiency is the root pattern in most cases of premenstrual water retention. The spleen governs the transformation and transportation of fluids throughout the body — when it is weakened (by overwork, irregular eating, excessive sugar and refined carbohydrates, cold foods, or chronic worry), fluid accumulates as dampness rather than being properly distributed and excreted. This dampness tends to accumulate in the lower burner and the tissues in the days before the period when the body's energetic resources are most taxed.
Liver qi stagnation compounds the problem by disrupting the smooth flow of qi needed to move fluids efficiently. When liver qi is stagnant — due to stress, frustration, or insufficient rest — fluid stagnation follows. This is why water retention is so often accompanied by other premenstrual symptoms including irritability, breast tenderness, and mood changes.
Acupuncture
Acupuncture addresses both the root patterns and the branch symptom effectively. Points that strengthen the spleen, move liver qi, and drain dampness — including SP 6 (Sanyinjiao), SP 9 (Yinlingquan), ST 36 (Zusanli), and LV 3 (Taichong) — are combined with points that regulate the thoroughfare and conception vessels. Treatment timed in the mid-luteal phase (around day 18–22 of a 28-day cycle) is particularly effective for premenstrual symptoms.
Chinese Herbal Medicine
For spleen qi deficiency with dampness, formulas that tonify the spleen and resolve dampness are indicated — Shen Ling Bai Zhu San is a classical choice. Where liver qi stagnation is prominent, a liver-regulating formula such as Xiao Yao San addresses the underlying driver. For fluid retention with more pronounced coldness, Wu Ling San provides targeted fluid-transforming action.
Dietary Advice
Reducing salt intake in the week before the period directly reduces fluid retention. Avoiding cold, raw, and damp-producing foods — dairy, wheat, refined sugar, alcohol — supports spleen function. Foods that drain dampness include barley, adzuki beans, Yi Yi Ren (Job's tears), and corn silk tea. Adequate magnesium intake reduces aldosterone-driven sodium retention.
