Does bad stomach lead to menstruation ahead of schedule?

A bad stomach generally does not lead to menstruation in advance, and may indirectly affect menstruation.

Menstruation in advance refers to the continuous multiple menstrual cramps time 7 days or more in advance. In general, a bad stomach does not directly lead to menstruation in advance, because the digestive system does not directly affect the reproductive system. However, if the stomach is not good for a long time, it will affect the digestion and absorption of food, and may cause malnutrition. Long-term malnutrition may cause ovarian ovulation disorders, menstrual disorders, etc., and indirectly induce menstruation in advance.

In addition, the causes of menstruation in advance include luteal insufficiency, endometriosis, adenomyosis, pituitary gland or hypothalamic lesions.
