Why Do I Gain Weight Before My Period?

Weight gain is a normal symptom of premenstrual syndrome, or PMS. This symptom of PMS is due to water retention.

  1. Definition

    • Water retention occurs when your body retains more water than it should. This can cause a slight increase in weight as well as bloating.

    Causes

    • According to the Mayo Clinic, it is unclear why women experience symptoms of PMS, or why water retention occurs directly before a woman's period. It is suggested that the hormonal changes in the body play a large part.

    Symptoms

    • Symptoms of water retention include a slight increase in weight, bloating and feeling heavier.

    Prevention/Solution

    • According to the Mayo Clinic website, lowering salt intake, being physically active and eating healthier can help reduce water retention before a woman's period.

    Treatment

    • Water retention is not always preventable, but it is treatable. There are many over-the-counter medications available, such as Midol or Pamprin, that relieve water retention and other symptoms of PMS.
