Does weight increase before menstruation?

Recently, my period arrived. A few days before menstruation, why do I always feel bloated and swollen? My clothes and shoes suddenly seem tighter—shoes that fit comfortably in the morning become stiff and painful by evening. Under these circumstances, many women commonly experience discomfort for several days each month, typically beginning about one week before their period starts. So, does weight actually increase before menstruation?

Does weight increase before menstruation?

Yes, weight often increases before menstruation. Cravings for sweets and refined carbohydrates—such as white rice, bread, and pasta—elevate insulin levels in the body, prompting the ovaries to overproduce androgens and suppress ovulation. In obese women, excess body fat continuously converts androgens into estrogen; however, abnormal estrogen concentrations—lacking the normal cyclical fluctuations—also impair regular ovulation. Moreover, a woman’s physiological menstrual cycle itself influences body weight. In fact, there’s no need to feel overly distressed or elated about this—it is entirely driven by fluctuations in estrogen levels within the body.

During the five days leading up to menstruation, avoid high-calorie, overly salty, or excessively fatty foods—and abstain from alcohol. Additionally, although edema (fluid retention) is common during this time, it’s especially important to drink plenty of water to promote blood circulation and metabolic activity, and to increase physical activity. Doing so helps prevent alarming numbers on the scale and minimizes the severity of bloating. During your period, try to avoid sweets and high-calorie foods, as their high caloric content may contribute to weight gain.
