FAQ

Questions you might have

We've gathered answers to the questions women ask most often about perimenopause.

Perimenopause is the transition period leading up to menopause, when your body begins producing less estrogen. It can start 8-10 years before menopause. Menopause is officially diagnosed when you've gone 12 consecutive months without a period. After that point, you're considered postmenopausal.

Most women begin perimenopause in their mid-40s, but it can start as early as the mid-30s or as late as the mid-50s. If you're experiencing symptoms before age 40, it's important to speak with your doctor as this could indicate premature menopause.

Yes, pregnancy is still possible during perimenopause. Even if your periods are irregular, you may still be ovulating. If you don't wish to become pregnant, continue using contraception until you've been period-free for 12 consecutive months.

If your symptoms are interfering with your daily life, work, relationships, or sleep, it's worth talking to a healthcare provider. There are many treatment options available, from lifestyle changes to hormone therapy. You don't have to simply 'push through' debilitating symptoms.

The duration varies significantly. Perimenopause typically lasts 4-8 years, though some women experience it for as little as a few months or as long as 10+ years. Symptoms like hot flashes often decrease after menopause but can continue for several years into postmenopause.

Hormone therapy (HT) can be very effective for managing perimenopause symptoms, particularly hot flashes, night sweats, and vaginal dryness. However, it's not right for everyone. Discuss your medical history and risk factors with your healthcare provider to determine if HT is appropriate for you.

Anxiety during perimenopause is extremely common and often catches women off guard. Fluctuating estrogen levels directly affect neurotransmitters like serotonin and GABA, which regulate mood and anxiety. If you've never experienced anxiety before, know that this is a recognized symptom and help is available.

Absolutely. Regular exercise, stress management, adequate sleep, and a balanced diet can significantly reduce symptoms. Limiting alcohol, caffeine, and spicy foods may help with hot flashes. While lifestyle changes may not eliminate all symptoms, many women find they provide meaningful relief.
