What are the potential causes of a missed period besides pregnancy?

There are multiple reasons why you might miss a period that are unrelated to pregnancy. One common cause is stress; when you're very stressed, your body may change how your hormones work, which can affect your cycle. Another reason is hormonal imbalances like thyroid problems or polycystic ovary syndrome (PCOS) that disrupt regular periods. Changes in body weight, whether from significant weight loss or gain, can sometimes cause your body to slow down or stop your menstrual cycle. Intense exercise or changes in your routine may also play a role. In some cases, medical conditions or certain medications can affect your hormones and lead to a missed period. These disruptions are usually temporary, but if your period remains absent, it might be a sign to talk with your doctor for a proper check-up. Understanding what is usual for your body and noticing any changes can help you catch these issues early.
