Introduction
Menstrual periods that occur earlier than usual are generally not normal and may be caused by physiological factors or pathological conditions, such as uterine fibroids or endometriosis. Besides these reasons, they could also result from conditions like endometrial polyps. It is recommended to go to the hospital for a comprehensive examination and receive targeted treatment based on the underlying cause.

Menstruation that occurs earlier than usual is generally not normal and may be caused by physiological factors or pathological conditions such as uterine fibroids or endometriosis.

I. Physiological Causes

In daily life, excessive physical fatigue, prolonged熬夜 (staying up late), or irregular eating habits can lead to endocrine disorders. This may result in insufficient luteal function, thereby affecting the normal menstrual cycle and causing menstruation to occur earlier.

II. Pathological Causes

1. Uterine Fibroids

Uterine fibroids that grow into the uterine cavity can enlarge the surface area of the endometrium. This often interferes with normal uterine contractions, leading to an earlier menstrual cycle.

2. Endometriosis

When endometrial tissue grows outside the uterus, it can cause fibrosis of surrounding tissues. This commonly leads to pelvic bloating or affects the pelvic peritoneum, resulting in changes to the menstrual cycle, possibly causing earlier menstruation.

Besides the above-mentioned causes, early menstruation could also be due to conditions such as endometrial polyps. It is recommended to undergo a comprehensive medical examination at a hospital to identify the underlying cause and receive targeted treatment. In daily life, it's also important to keep the abdomen warm and avoid getting chilled.
