After constipation improved, menstruation became delayed.

Constipation and delayed menstruation are usually unrelated. Menstrual delay may be caused by normal physiological variations, polycystic ovary syndrome (PCOS), uterine fibroids, or other reasons, and can be managed through general measures or medication. Specific analyses are as follows:

1. Normal physiological phenomenon

The menstrual cycle is regulated by multiple hormones within the female reproductive system. Under normal conditions, the ovaries release eggs cyclically, while the endometrium undergoes periodic growth and shedding, forming the menstrual cycle. A variation of up to seven days earlier or later than expected is considered normal and does not require special treatment.

2. Polycystic ovary syndrome (PCOS)

PCOS is associated with imbalances in androgen and estrogen levels in the body. Hormonal changes may affect the regularity of the menstrual cycle. Patients can take medications such as progesterone capsules or spironolactone tablets under medical supervision to alleviate symptoms.

3. Uterine fibroids

Uterine fibroids are common benign tumors in women, typically growing within the uterine wall. Their development is related to fluctuations in estrogen and progesterone levels. Fibroids may interfere with the normal growth and shedding of the endometrium, leading to menstrual cycle irregularities. Patients can use medications such as Hongjin Xiaojie Capsules or Shuangju Granules under a doctor's guidance for treatment.

Besides the above causes, delayed menstruation may also result from endometriosis, cervical tumors, or ovarian tumors. In daily life, appropriately adjusting diet by increasing dietary fiber intake, maintaining physical activity, and cultivating a positive mindset and healthy lifestyle habits can help maintain overall health and prevent disease.
