If your mood, confidence or ability to cope has changed during perimenopause or menopause, there is very likely a biological reason for it. Hormones have a powerful effect on the brain, and when levels fluctuate or fall, mental health can be affected in ways that are just as real as any physical symptom. For too long, these experiences have been attributed to stress, personality or life circumstances, while the hormonal cause goes unaddressed.

Why hormones affect how you feel

Estrogen, progesterone and testosterone all play important roles in brain function. They influence the body’s chemical messengers including serotonin and GABA, which help regulate mood, calmness, motivation and sleep. When these hormones fluctuate during perimenopause or remain low after menopause, the effects can be wide-ranging.

Some women suddenly feel anxious. Others notice irritability, tearfulness, low self-esteem, emotional flatness or a sense of having lost themselves. These are not signs of weakness or instability. They are a recognised consequence of changing hormone levels, which deserves to be taken seriously and treated accordingly.

Mental health symptoms are common – and commonly missed

Many women experiencing perimenopause and menopause-related mental health symptoms are not told that hormones could be at the root of it. Instead, they may be offered antidepressants without any discussion of whether hormonal change is contributing. Antidepressants do have an important role for some women, particularly those with clinical depression, but they do not replace hormones. For many women with menopause-related mood symptoms, addressing the hormone changes directly is the most effective approach.

Research by Newson Global makes this clear. It found that identifying hormone-related mood symptoms and considering hormone treatment early helped women avoid the unnecessary long-term use of medications that do not address the underlying cause.

Sleep is also central here. Night sweats, early waking and difficulty settling can quickly compound mood symptoms. They all work to lower stress tolerance, worsening anxiety and making low mood feel heavier. Mental health challenges in menopause are therefore often driven by a combination of direct hormone effects on the brain and the knock-on effects of sustained poor sleep.

What helps

Hormone treatment is the recommended first-line treatment for menopausal mood disturbance, and for most women the benefits outweigh any risks. Estradiol has been shown to help with depressive symptoms when given through the skin. Progesterone can support calmness through its action on brain receptors. Testosterone can play a valuable role in psychological wellbeing, including low mood, motivation and anxiety.

Research has also shown that many women report significant improvements in mental health symptoms after starting hormone treatment. For some, a combination of hormone treatment and other support works best.

Individual care matters

There is no single presentation of menopause-related mental health symptoms, which is why there is no single treatment. Some women feel mainly anxious. Others feel low, angry, foggy or emotionally detached. Some symptoms are tightly linked to poor sleep, while others flare in relation to changing cycles. Your age, your stage of menopause, your medical history and which symptoms are most affecting your life all shape the best approach.

If treatment is not working well enough, that is worth raising rather than accepting. Many women need adjustments over time. Therapy, peer support and lifestyle changes can all help alongside medical treatment, but they work best when hormone deficiency is also being addressed.

When to seek help

If you are feeling persistently low, highly anxious, unable to sleep or simply unlike yourself, speak to a doctor who understands both hormones and mental health. Symptoms affecting the mind deserve the same level of attention as symptoms affecting the body. If you are already on hormone treatment and still struggling, the dose, type or balance of hormones may need reviewing.

You do not need to frame this as a mental health crisis to be taken seriously. You simply need to describe what has changed and find a medical professional who will listen to the whole picture.
