7 Symptoms of Premenstrual Syndrome
Mood Swings
Women with premenstrual syndrome might experience mood swings. This means that they will cry or laugh for no obvious reasons at any time. In addition, they would have feelings of irritability, sadness, depression, anger, or anxiety in the same day. All of these changes are caused by a decrease in the levels of estrogen in the luteal phase, which begins from the ovulation day. As a result, it causes a decline in the amount of serotonin. This is an important substance in the brain that helps regulate your sleep and mood patterns. Without a sufficient amount of serotonin, women will have some considerable mood changes. [3]
