Is a 24-day menstrual cycle normal, and why is the cycle short?

Generally, a 24-day menstrual cycle falls within the normal range. Most women have cycles between 21 and 35 days. As long as the cycle remains consistently regular without significant discomfort, there is usually no need for excessive concern. If in doubt, it is advisable to seek medical consultation promptly. Detailed analysis is as follows:

If the menstrual cycle has consistently remained stable at 24 days, with no notable changes in menstrual flow or duration, and without symptoms such as increased abdominal pain, abnormally heavy or light bleeding, this indicates regular ovulation and stable endocrine function. It represents an individual variation of a normal menstrual cycle and does not require special intervention.

If the menstrual cycle was previously not 24 days but suddenly shortens to 24 days, or becomes irregular with fluctuating lengths, accompanied by abnormal menstrual flow, prolonged periods, or abdominal pain, it may be related to endocrine imbalances, ovarian function changes, emotional fluctuations, or irregular lifestyle habits. In such cases, attention should be paid to bodily signals and potential contributing factors should be evaluated.

In daily life, it's important to maintain a regular sleep schedule, avoid excessive fatigue and large emotional swings, and ensure a balanced diet. If the menstrual cycle changes suddenly and persists for three consecutive cycles or more, or if it is accompanied by significant discomfort, timely medical evaluation is recommended.
