Mood swings are common symptom of menopause. Low estrogen levels can lead to irritability, anxiety, and depression. Your moods can change quickly and vary greatly, from laughing to crying within minutes.

How are estrogen levels connected to your mood? Some studies point to the mood-enhancing effects of the hormone, which implies that lower levels of it may lead to feelings of depression. In fact, one study showed that women are two to four times more likely to experience a major depressive episode during menopause than at other times in their lives.

Menopause and low estrogen levels may also exacerbate existing mental health issues, such as bipolar disorder and schizophrenia.

In addition to changing estrogen levels, sleepless nights can also contribute to mood changes. Night sweats, hot flashes, and heart palpitations at night can leave you feeling cranky, anxious, and irritable during the day.
