What are the symptoms of premenstrual syndrome (PMS)?
Generally, "Yi Ma" refers to menstruation. Premenstrual periods may be accompanied by symptoms such as mood swings, breast tenderness, abdominal discomfort, vaginal discharge, increased sleepiness, and others. If discomfort occurs, timely medical consultation is recommended. Detailed explanations are as follows:

1. Mood Swings
Due to hormonal changes, women may experience mood swings before menstruation, such as irritability, anxiety, depression, or emotional instability. This is caused by the impact of fluctuating hormone levels on emotions.
2. Breast Tenderness
Many women feel breast tenderness or sensitivity before their period due to hormonal fluctuations. This may be caused by hormonal changes leading to breast duct proliferation.
3. Abdominal Discomfort
Uterine contractions or pelvic congestion may cause some women to experience mild abdominal pain, bloating, or a feeling of heaviness in the lower abdomen before menstruation.
4. Increased Vaginal Discharge
Menstruation is the result of cyclical changes in the endometrium. Before menstruation, changes in hormone levels in the body can lead to increased secretion from endometrial glands, resulting in increased vaginal discharge.
5. Sleepiness
Some women may feel particularly fatigued before menstruation, leading to increased sleepiness. This may be related to hormonal changes and the body's preparation for the menstrual cycle.
These symptoms usually subside gradually once menstruation begins. In daily life, women are advised to regulate their emotions, avoid anxiety, and maintain a balanced diet and healthy lifestyle habits before their period.
