Perimenopause is a natural stage in the lives of many women and marks the beginning of the transition toward menopause.
While many women recognize the symptoms of perimenopause, others may not realize that they are already going through this process.
Below, we explain what perimenopause is, its most common symptoms, and the causes behind it.
Everything You Need to Know About Perimenopause

1. What Is Perimenopause?
Perimenopause is the transition period before menopause, when the ovaries begin producing less estrogen—the main hormone that regulates the menstrual cycle.
This phase can last several years, typically between 4 and 8 years, and often begins in a woman’s 40s, although some women experience symptoms earlier.
Perimenopause ends when menopause is reached, which is defined as the absence of menstruation for 12 consecutive months.
2. Common Perimenopause Symptoms
Symptoms vary from woman to woman, but some of the most common perimenopause symptoms include:
- Menstrual Irregularities: Menstrual cycles may become shorter or longer, and bleeding patterns can change. Some women experience very heavy periods, while others notice lighter-than-normal flow.
- Hot Flashes and Night Sweats: One of the most well-known symptoms, hot flashes cause sudden sensations of intense heat and may be accompanied by sweating. Night sweats occur during sleep and can significantly disrupt rest.
- Sleep Disturbances: Difficulty sleeping is common during perimenopause. Women may experience insomnia or wake up several times during the night due to night sweats or hormonal fluctuations.
- Emotional Changes: Hormonal imbalance can lead to mood changes, including irritability, anxiety, sadness, or even depression. Lack of sleep can further intensify these symptoms.
3. What Are the Causes?
The primary cause of perimenopause is the decline in reproductive hormone production—especially estrogen and progesterone—by the ovaries.
This process is completely natural, but other factors can influence when it begins and how it progresses:
- Age: The average age to begin perimenopause is between 45 and 55, although some women start earlier.
- Genetics: Family history plays an important role. If your mother experienced early perimenopause, you may be more likely to as well.
- Lifestyle: Stress, diet, alcohol consumption, and smoking can affect the duration and intensity of perimenopause symptoms.

4. How Can You Tell If You’re in Perimenopause?
Although symptoms can be a clear indicator, some women do not associate them with perimenopause—especially if they have not yet noticed menstrual irregularities.
If you are over 40 and experiencing some of the symptoms mentioned above, it is recommended that you consult a doctor.
Hormone tests can help confirm the diagnosis, although in most cases, perimenopause is diagnosed based on symptoms and medical history.
5. How to Manage the Symptoms

Although perimenopause is a natural phase, its symptoms can be uncomfortable. Here are some recommendations to manage them:
- Maintain a balanced diet: Eating foods rich in calcium and vitamin D, and avoiding highly processed foods, can help manage symptoms.
- Exercise regularly: Physical activity such as walking or practicing yoga can reduce hot flashes, improve mood, and promote better sleep.
- Consult a doctor: If symptoms are severe or interfere with your quality of life, medical treatments—such as hormone therapy—may be effective in relieving perimenopause symptoms.
Perimenopause is a natural stage that marks an important transition in a woman’s life, but its symptoms can be challenging if they are not recognized or properly managed.
Understanding the signs and causes of this phase can help you approach it with greater clarity and make informed decisions about your health.
If you are experiencing changes in your menstrual cycle, hot flashes, or emotional shifts, do not hesitate to consult your doctor for personalized guidance and to explore available treatment options.
