What Could Cause Extreme Fatigue Before My Period?

Extreme fatigue before your period is often linked to the natural hormone changes of premenstrual syndrome (PMS) or, in some cases, premenstrual dysphoric disorder (PMDD). These shifts can make you feel very tired, sometimes along with other symptoms like mood swings or sleep problems.

Explanation

Before your period, many women notice that they feel extra tired, and this is usually related to PMS. In the days leading up to your period, your body goes through changes due to shifting hormone levels. These changes can make you feel very fatigued, as well as cause other symptoms such as mood swings, irritability, trouble sleeping, or difficulty concentrating. For some, these symptoms are more intense and might be a sign of PMDD, a more severe form of PMS. While it is normal to feel tired before your period, you can try a few things to help manage this fatigue. Eating a balanced diet, getting regular exercise, and making sure you have good sleep habits can help boost your energy. If the tiredness is really severe or affects your daily activities, it’s a good idea to speak with your healthcare provider. They can check if it’s just normal PMS or if something else might be causing your extreme fatigue and recommend ways to help you feel better.
