Estrogen deficiency

If estrogen secretion is imbalanced, or the proportion of various estrogen is imbalanced, abnormal reactions in reproductive physiology and subjective sensation may occur. Low estrogen can affect egg development; imbalance of various estrogen ratios can cause abdominal distension, headache, mood swings, sensitivity and irritability before menstruation, and can cause irregular menstruation. In addition, if the level of estrogen declines too quickly, it can also cause discomfort symptoms specific to menopause. Finally, a lack of estrogen can also accelerate bone loss and increase the risk of heart disease.
