When we talk about menopause, we often focus on hot flashes, sleep disruption, or weight changes. But there’s another category of symptoms that deserves far more attention: mood changes.
An estimated 70% of women experience significant mood shifts during perimenopause and menopause. And yet, mental health remains one of the hardest parts of this transition to talk about—much like menopause itself.
These changes may show up as:
- Irritability
- Low mood or depression
- Mood swings
- Anxiety
- Sadness
- Anger or rage
If you’re experiencing any of this, I want to say clearly: what you’re feeling is real—and it’s not a personal failure.
For many, menopause comes with a dramatically lower tolerance for other people’s BS. Learning to create firmer boundaries helps—but these are deep biological changes. Some women feel flat, unmotivated, or withdrawn. Others experience a simmering anger that feels unfamiliar and, at times, overwhelming. Too often, that anger gets misdirected at partners, coworkers, children or ourselves—especially when we don’t understand where it’s coming from.
Why Am I Feeling This Way?
While many hormones shift during the menopause transition, estrogen is the main driver of these mood changes.
Estrogen receptors are found throughout the body—including the gut, muscles, skin, and brain. In the brain, estrogen plays a critical role in regulating temperature, stress response, cognition, and emotional control.
Neuroscientist Dr. Lisa Mosconi describes perimenopause as a renovation phase for the brain. As estrogen levels fluctuate and decline, the brain undergoes structural and functional changes to prepare for the next phase of life. And if you’ve ever lived through a home renovation, you know how disruptive—and messy—that process can be.
Research from Weill Cornell Medicine shows that as women move from premenopause into perimenopause and postmenopause, estrogen receptor density actually increases in certain brain regions. In postmenopausal women, higher receptor density in the thalamus has been associated with depressed mood, while changes in the prefrontal cortex and hippocampus have been linked to lower cognitive scores. Researchers are still exploring how menopausal hormone therapy (MHT) influences these receptor changes, mood, and cognition.
At the same time, declining estradiol (the most potent form of estrogen) affects key neurotransmitters:
- Serotonin, which supports mood, sleep, appetite, and emotional regulation, tends to decline alongside estrogen—contributing to depression, anxiety, and irritability.
- Dopamine, essential for motivation, focus, and reward, is also estrogen-dependent. Low dopamine is strongly associated with depression.
- Glutamate, the brain’s primary excitatory neurotransmitter, supports energy, cognition, and mood. Low levels are linked to depression and fatigue.
Stress Hormones Matter, Too
Cortisol—the body’s primary stress hormone—often rises as estrogen falls. Overnight cortisol levels increase in later stages of menopause, and cortisol spikes can occur during hot flashes. Progesterone helps buffer this stress response, which is one reason its decline matters so much.
Elevated cortisol can lead to anxiety, racing thoughts, sleep disruption, irritability, and anger. Over time, it also contributes to abdominal weight gain—something many women notice during this transition.
There Is a Positive Side
While the road through menopause can be bumpy, the destination often brings meaningful gains. Postmenopausal women frequently show greater emotional and cognitive empathy, improved self-understanding, and increased self-compassion. Many women report feeling more grounded, authentic, and clear about what truly matters.
Getting there, however, takes support.
How to Manage Menopause-Related Mood Changes
At Tendwell, I take a whole-person approach. For many women, mood support during menopause may include lifestyle changes, menopausal hormone therapy (MHT), and—in some cases—medications for underlying mental health conditions.
A Note on Antidepressants
When women seek help for mood symptoms during perimenopause, antidepressants are often the first (and sometimes only) option offered. There’s growing concern that they may be overprescribed during this life stage—often without addressing the hormonal drivers underneath.
Antidepressants can absolutely be helpful for some women, particularly when there’s a history of depression or anxiety. And if you’re struggling with persistent low mood, anger, or distress, working with a mental health professional is essential.
What concerns me is that many women are not offered hormone therapy, despite strong evidence that it can be just as effective for mood—and offers additional benefits for bone, brain, and cardiovascular health.
Menopausal Hormone Therapy (MHT)
A 2025 study from Cambridge University followed over 900 perimenopausal and menopausal women using hormone therapy, including transdermal bioidentical estradiol, progesterone, and testosterone. After just over three months, women reported a 44% reduction in depression symptoms, along with overall mood improvement. Those using estradiol combined with progesterone and testosterone experienced the greatest benefit.
Meditation and Mindfulness
Research shows that mindfulness practices reduce stress, improve sleep, and increase emotional resilience. Even short, consistent practices can help calm the nervous system during this hormonally sensitive time.
Apps like Headspace and Calm make it easy to begin.
Exercise (The Right Kind)
Movement is one of the most effective tools we have for mood support. Research shows that:
- Low- to moderate-intensity exercise reduces depressive symptoms
- Mind-body practices like yoga, Pilates, and tai chi are especially helpful
- Aerobic movement supports both depression and anxiety
The key is consistency—not intensity.
Sleep Is Foundational
Sleep is when the brain repairs itself and clears metabolic waste. Prioritizing sleep hygiene can dramatically improve mood stability. I encourage women to:
- Get bright morning light
- Limit afternoon caffeine
- Eat dinner at least three hours before bed
- Power down screens two hours before sleep
- Reassess alcohol, which often worsens sleep quality
Oral micronized progesterone can also be helpful when taken about an hour before bedtime.
An Anti-Inflammatory Way of Eating
Inflammation is strongly linked to depression. An anti-inflammatory diet—rich in colorful vegetables, lean protein, fiber, and healthy fats—supports both brain and hormonal health.
I encourage patients to focus on foods like:
- Salmon, turkey, and chicken
- Beans and legumes
- Olive oil and avocado
- A wide variety of fruits and vegetables
Diets higher in healthy fats and protein are associated with less anxiety and depression, while higher carbohydrate intake may worsen mood symptoms for some women.
The Bottom Line
Mood changes during menopause are biological, real, and treatable. With the right support, this transition can become a powerful reset—not just hormonally, but emotionally and mentally as well.
You don’t have to white-knuckle your way through it. And you don’t have to do it alone.
If you’re struggling with mood changes during perimenopause or menopause, this is exactly the kind of work we do at Tendwell.
