Introduction
Menstrual delay may be caused by factors such as pregnancy or excessive dieting. In women of childbearing age with regular sexual activity and inadequate contraception, pregnancy is a likely cause of missed menstruation. The first clinical sign of pregnancy is often delayed menstruation; if the delay exceeds 7–10 days, a home pregnancy test can be used for detection. Some women commonly resort to restrictive dieting to maintain a slim figure and control body weight.
Healthy women of childbearing age typically experience menstruation once a month, lasting approximately 3–7 days. If menstruation is suddenly absent or significantly delayed, it may indicate an underlying health issue, and the cause should be investigated promptly. So, what causes delayed menstruation?
Causes of Delayed Menstruation
Delayed menstruation may result from factors such as pregnancy or excessive dieting. In women of childbearing age with regular sexual activity and inadequate contraception, pregnancy is a common cause of missed periods. The first clinical sign of pregnancy is often menstrual delay; if menstruation is delayed by more than 7–10 days, a home pregnancy test can be used for initial detection. Some women routinely restrict food intake to maintain a slim figure and control weight. While moderate dietary adjustments are generally safe and may support healthy weight management, extreme or prolonged caloric restriction can impair nutrient intake and disrupt endocrine function—potentially leading to reduced menstrual flow or amenorrhea.
Delayed menstruation can be treated pharmacologically. For women experiencing prolonged menstrual cycle irregularities, hormonal therapy—such as appropriate doses of progesterone or estrogen—may help regulate the cycle. Additionally, various medications may be prescribed depending on the specific presentation. Traditional Chinese medicine (TCM) may also be employed to address underlying imbalances contributing to menstrual irregularities, with herbal formulations tailored to individual symptoms.
Patients are advised to pay attention to their dietary habits, consume nutritionally rich foods, and avoid smoking and alcohol consumption. We hope this information is helpful to you.
