Your sex hormones influence your brain and, consequently, your emotions. Both oestrogen and progesterone play a role in this.
Oestrogen stimulates the production of the happiness hormone serotonin. When oestrogen levels fluctuate and decline during menopause, it impacts the amount of serotonin in your brain. This can make you feel down, sad, or indifferent. You may also experience crying spells and feelings of grief.
Progesterone has a calming effect on the brain. When progesterone levels drop, you may feel restless or tense, even without a clear reason. Additionally, progesterone is needed for the conversion of the thyroid hormone T4 into T3. While this is a technical process, a decrease in progesterone can impair thyroid function, making mood swings, low mood, or feelings of agitation more likely.
Sadness and grief can manifest as crying spells, feelings of hopelessness or worthlessness, and a loss of interest in daily activities. You may also feel indifferent. Know that you are not alone. Research shows that 40 per cent of women in menopause experience feelings of low mood or depression. The likelihood of mood-related symptoms is higher in the years leading up to menopause and the first few years after your last period. If you experienced low mood or mood swings before menopause, you are more likely to face them again during this phase.
