What causes menstruation to come one week early?

A woman's menstrual cycle is generally 28 to 30 days. Menstrual blood is usually dark red, and the bleeding will end in about 3 to 5 days. However, in life, women may experience changes in their menstrual cycle due to excessive mental stress or encountering some special things. If menstruation suddenly comes a week earlier, it is very likely caused by excessive mental stress. It is important for women to adjust their daily life and family and maintain a stable and happy mood.

Menstruation is a manifestation of the periodic shedding and bleeding of the endometrium. The cyclical changes in the endometrium are caused by the cyclical changes in the ovaries. The menstrual cycle is regulated by a complex neuroendocrine system and is completed by the central nervous system, pituitary gland, ovaries and uterus. Problems in any of these links will affect menstruation. For example, emotional tension, environmental changes, diet and medication will cause changes in the menstrual cycle and menstrual volume.

The decline of ovarian function can also reduce the menstrual volume. In patients with endometrial diseases, the menstrual cycle is basically normal, but the menstrual volume is significantly reduced, or even just a drop of menstrual blood stops. In patients with menstrual period shortened to less than two days and little menstrual blood, you should be alert to the low estrogen level.

In addition to the sudden early or late menstruation caused by functional diseases, another reason is nutritional deficiency. Modern women, especially younger ones, have higher requirements for their body shape. Sometimes they go on a diet to lose weight and maintain a good figure. Excessive dieting can easily lead to insufficient nutrition and cause changes in the menstrual cycle. It is better to maintain a healthy body shape and should not excessively demand thinness.
