Whether it is serious or not depends mainly on the age of the patient.
Older patients, who have reached the age of menopause, are generally not considered serious if they have not had a period for four months, but have no other accompanying symptoms. This indicates that the amenorrhea is caused by the decline of ovarian function due to aging.
If the patient is a woman of childbearing age and has not had a period for four months, it is more serious. This indicates a menstrual disorder and the presence of an endocrine disorder, which often affects ovulation, can cause infertility, and even has the potential to increase the risk of endometriosis.
In the case of adolescent women, four months without menstruation may be normal due to the underdevelopment of the hypothalamic-pituitary-ovarian axis. However, we can’t rule out pathologic factors causing menstrual disorders.
If a woman does not have her period for four months, she should go to the hospital for an examination to determine the reason for her lack of menstruation, and then follow the doctor’s instructions and then carry out targeted treatment.
