The menstrual cycle is the time from the first day of one period to the beginning of the next. On average, the cycle lasts from 25 to 35 days, all women have different organisms, therefore, the timing is different. Failure to comply with this norm is not always a sign of ill health, but this is a reason to consult a doctor.
Length of the menstrual cycle
A 28-day menstrual cycle is considered ideal, which means that exactly 28 days pass from the beginning of one period to the beginning of the next. But under the influence of the environment, the state of health and the reproductive system, the woman's lifestyle, the cycle length changes: for some women it is 25 days, for others 30 or more. Doctors consider the cycle duration from 21 to 35 days to be the norm, and if there is a deviation from this norm, it is advisable to check with a gynecologist and exclude possible diseases. If the cycle goes beyond these limits once or twice a year, but for no more than ten days, this is normal.
A too short or too long cycle does not always indicate the presence of problems, this may be an individual feature of a woman, but it is recommended to do an examination.
The length of the menstrual cycle can vary throughout a woman's life. With age, with a change in the environment and lifestyle, due to diseases and other factors, the cycle can become shorter or longer, if it remains regular, this is not a cause for concern.
Deviations from the norm
During the first year or two after the onset of the first menstrual period, a girl's menstrual cycle is irregular, several months can pass between periods, this is normal. In some cases, adolescents have a very short cycle. Over time, the cycle stabilizes, but if after a few years this has not happened, consultation with a gynecologist is needed.
Cycle times may change and become out of range after pregnancy or breastfeeding. In women who are breastfeeding, menstruation occurs at the end of lactation, and the cycle is restored in a few months. With mixed feeding 3-4 months after giving birth, menstruation appears, but the cycle also does not immediately become regular.
The duration of the cycle also changes before menopause, first for a few days, then months. When menstruation is absent for over a year, menopause occurs.
Deviations in the duration of menstruation from the norm can be associated with inflammation of the genital organs, tumors - myomas, ovarian cysts, endometritis. In some cases, congenital problems with the reproductive system lead to too short or too long menstrual periods. Chronic diseases that are not directly related to the genitals can also affect menstruation: diabetes mellitus, thyroid disorders.
