What are the reasons for a ten-day delay in menstruation?

Generally speaking, "例假" refers to menstruation. A delay of ten days in the menstrual cycle may be caused by pregnancy, weight changes, excessive stress, medication effects, polycystic ovary syndrome (PCOS), or other factors. If discomfort occurs, it is recommended to seek medical advice promptly. Specific causes are analyzed as follows:

1. Pregnancy

After a fertilized egg implants into the uterine lining, the endometrium no longer sheds, preventing the formation of menstruation and resulting in a delayed period. It is advisable to seek medical attention promptly.

2. Weight Changes

Sudden weight fluctuations can alter hormone synthesis and metabolism in adipose tissue, potentially disrupting the normal menstrual cycle. It is important in daily life to gradually adjust eating habits, ensure balanced nutrition, and avoid extreme dieting.

3. Excessive Stress

Stress can affect the function of the hypothalamic-pituitary-ovarian axis, thereby interfering with the normal secretion of estrogen and progesterone, leading to either prolonged or shortened menstrual cycles. Stress can be reduced through physical exercise, meditation, yoga, and similar methods.

4. Medication Effects

Drugs such as contraceptives, antidepressants, and antipsychotics may delay the menstrual cycle by affecting the endocrine or central nervous systems. Dosages should be adjusted or medications changed under a doctor's guidance, and discontinuation may be necessary when indicated.

5. Polycystic Ovary Syndrome (PCOS)

PCOS may be related to genetic factors. Patients often have multiple immature follicles in the ovaries, which disrupt normal hormone levels and lead to delayed menstrual cycles. Symptoms may include hirsutism, acne, and weight gain. Treatment should follow medical advice and may include medications such as ethinylestradiol/cyproterone acetate tablets, dydrogesterone tablets, and metformin hydrochloride tablets.

In daily life, it is important to maintain healthy habits, such as eating a balanced diet and engaging in regular moderate exercise like walking or swimming, which helps maintain a healthy body weight.
