What is the reason for a delay of four or five days in menstruation?

Patient's question:

Patient Gender: Female
Patient Age: 34
Menstruation is delayed by four or five days, what's going on? I'm not pregnant either.

Doctor's answer:

Premenstrual, a delay of one week is normal. Fatigue, medication, and endocrine changes can all cause irregular menstruation. If menstruation does not occur for more than 10 days, and pregnancy is ruled out, it should be considered menstrual disorder and an endocrine examination is needed to identify the cause. The occurrence of gynecological diseases not only affects women's health but can also lead to the development of gynecological diseases. Therefore, it is best to go to the gynecology department of the hospital for a leukorrhea test. After identifying the cause, symptomatic treatment should be administered. Pay attention to dietary regulation in daily life, consuming light and easily digestible foods, and avoiding spicy, stimulating, and cold foods.
