What Are the Causes of Having Less Frequent Periods?

When your periods come less often, it may be because your body’s hormones are not working in the usual way. If you are sexually active and miss a cycle start date, you should have a pregnancy test. One reason is an energy imbalance. For example, if you lose too much weight or your body doesn’t have enough fuel because of heavy exercise or stress, your hormones might slow down, making your cycle longer. Conditions like polycystic ovary syndrome (PCOS) or other metabolic disorders can also cause less frequent periods. These issues change the hormone signals that tell your uterus when to build up and shed its lining, so your menstrual cycle may stretch out. Other factors, such as thyroid problems or a low-calorie diet, can also interfere with your menstrual cycle. Keeping track of your cycle and noting changes is very helpful. If you see that your cycle keeps getting longer over time, or if you have other symptoms that worry you, it might be a good idea to talk with a healthcare provider. They can check your hormone levels, review your overall health, and help find a way to bring back a more regular cycle.
