What Might Lead to an Increased Frequency of Periods?

Getting your period more often can happen if your cycle is shorter than usual, and this may be caused by factors like environmental exposures, stress, and lifestyle changes that affect your hormones.

Explanation

When your period comes more frequently, it often means that your menstrual cycle is shorter than the typical range of 21 to 35 days. One reason could be exposure to certain chemicals or environmental toxicants that disrupt your body’s hormones, leading to a faster cycle. Lifestyle choices also play a role. High levels of stress, changes in diet, or even sleep patterns can affect your hormonal balance, making your periods arrive sooner. Sometimes, these factors combine to change how your body builds up and then sheds the lining of your uterus, leading to more frequent bleeding episodes. Other hormone imbalances, possibly linked to conditions like thyroid disorders, might contribute as well. It is useful to track your cycle length and note any other changes. If you feel that your periods are becoming more frequent than what is normal for you and especially if the frequent cycles are causing fatigue or dizziness from more blood loss than normal, consider discussing it with a healthcare provider. They can evaluate your overall health, check your hormone levels, and provide guidance on how to manage these changes.
