Mood swings, brain fog, and night sweats aren’t just “in your head.” They might be early signs of perimenopause, long before your period ends.
When you’re in your 30s or early 40s, the last thing you expect is to feel like you’re falling apart. You’re still juggling work, relationships, and responsibilities—but suddenly you’re more anxious, exhausted, and emotionally frayed than ever before. Maybe you’ve even caught yourself wondering if you’re having a breakdown.
What most women aren’t told is that these could be symptoms of perimenopause, the transition phase that can start as early as your mid-30s. It’s not just about hot flashes. It’s about your body quietly beginning a complex hormonal shift, often misunderstood, misdiagnosed, or dismissed entirely.
Perimenopause is the hormonal bridge between your reproductive years and menopause. According to the Journal of Women’s Health Care, this transition can last anywhere from 2 to 10 years, with symptoms varying widely from one woman to another (Bin Abdulrahman et al., 2023).
For many, it begins subtly. You might start experiencing irregular cycles, heightened anxiety, brain fog, or a sudden inability to sleep through the night. Some women develop new joint pain or migraines. Others, like women who commented on the original discussion, describe overwhelming mood swings and even feelings of emotional instability that made them question their mental health.
What makes perimenopause so complex is that its symptoms mimic other conditions. Thyroid dysfunction, vitamin deficiencies, and chronic fatigue can all present similarly. This overlap often leads to years of misdiagnosis. One peer-reviewed study emphasized that perimenopausal symptoms are frequently overlooked, even though they can significantly impact a woman’s quality of life (Moyra et al., 2023).
Despite affecting nearly every woman, perimenopause is barely covered in medical training. In fact, research from BMC Women’s Health found that many primary care providers lack the depth of education to identify or treat perimenopausal symptoms effectively (Sanchez et al., 2019).
Women in their late 30s or early 40s are often told they’re “too young” to be in perimenopause. And if you’re on hormonal birth control, your symptoms might be even harder to detect. Birth control can mask changes in your cycle, making it more difficult to recognize the transition.
In one shared experience, a woman described how multiple doctors dismissed her concerns until one finally suggested a menopause resource. For her, it was a revelation—everything she had been feeling finally made sense.
The symptom list is longer than most expect. Perimenopause can include:
Because the symptoms don’t follow a linear path, it can feel like you’re constantly guessing what your body will do next. And while menopause itself is defined as 12 months without a period, perimenopause is the messy middle ground that can stretch on for years.
As one study notes, the hormonal fluctuations during this phase can increase cortisol levels and reduce serotonin, leading to mood changes and increased sensitivity to stress (Bin Abdulrahman et al., 2023).
Navigating perimenopause doesn’t have to be chaotic. While every woman’s path is unique, a few gentle steps may help ease the load.
First, advocate for yourself. If you feel your doctor isn’t listening, seek a second opinion or look for a provider trained in menopause care. Keep a symptom journal to help track patterns and bring evidence to your appointments.
Second, look at your nutrition. Some women find relief from brain fog and fatigue by ensuring they get adequate vitamin D and magnesium. In fact, one of the posters shared that her symptoms worsened due to a vitamin D deficiency that wasn’t initially detected. Supplementing with a high-quality vitamin D3 + K2 blend can help maintain hormonal balance and bone health.
Additionally, magnesium glycinate has been found to support sleep and calm the nervous system without causing digestive upset. It may be a worthwhile ally for those struggling with restless nights or heightened anxiety.
Always consult with your healthcare provider before starting a new supplement, especially during hormonal transitions.
Perimenopause isn’t just a phase to push through. It’s a profound biological shift that deserves awareness, support, and compassion. Too many women suffer in silence, blaming themselves for what they don’t understand.
If you’re feeling overwhelmed, you’re not alone. Start by learning. Track your symptoms. Seek out care providers who listen. And don’t be afraid to try nutritional supports that nourish your mind and body.
