Premenopause: the stage before perimenopause

Premenopause is the stage preceding perimenopause. It’s the time from your first period until the start of perimenopause. Every woman's experience of premenopause is different. During the last years of this stage, from roughly your mid-30s to your early 40s, your periods are still regular. There are a few noticeable changes in your body. You are still in your reproductive years but hormonal fluctuations may cause you to have some subtle or vague symptoms like mood changes or disturbed sleep. 

My hair is getting thinner, I don’t sleep as soundly as I used to, and I fly off the handle more easily. Knowing that my hormones are to blame has helped me take appropriate action. - Sara (age 37)

What is the difference between premenopause and perimenopause?

Premenopause and perimenopause are sometimes used interchangeably, but they have different meanings. Premenopause is the stage preceding perimenopause. Although, technically, premenopause isn’t a stage of menopause, it is important to acknowledge it. Even if you still have regular periods, you may have noticed some subtle symptoms. Do you have hot flashes or vaginal dryness? If so, then your body has started transitioning to menopause. The first stage of menopause, perimenopause, has begun. 

When does premenopause begin?

Officially, it’s the time from your first period. Premenopause is the stage preceding menopause. Technically, premenopause isn’t a stage of menopause. Not every woman experiences symptoms during premenopause. Usually, the first symptoms develop before the start of perimenopause when oestrogen levels are high relative to progesterone levels (oestrogen dominance).  

Menopause varies greatly from one woman to the next. What symptoms you will have, when they will occur, and how severe they will be cannot be predicted. Some women develop symptoms in their mid-30s, some in their early 40s, while others breeze through menopause with little or no difficulty. Sometimes, especially in younger women, early symptoms of menopause are often mistaken for something else, because many women believe menopause doesn't happen until the age of 50. 

What is the difference between premenopause symptoms and PMS symptoms?

Period symptoms, or premenstrual syndrome (PMS) symptoms, can be quite similar to the symptoms of premenopause, but there are some differences. 

  • PMS symptoms: PMS symptoms tend to recur in a predictable pattern: they begin one to two weeks before you get your period and then stop. PMS symptoms may get worse as you get closer to perimenopause due to falling progesterone levels and other hormonal changes. 
  • Premenopause symptoms: These symptoms do NOT recur in a predictable pattern but can occur at any time during you menstrual cycle and don’t stop after your period. Premenopause symptoms usually get worse over time. 
Hormonal changes during premenopause

Hormone levels fluctuate throughout your cycle. The closer you get to perimenopause (around age 35), oestrogen levels are still relatively high, while progesterone will slowly start to decline.  

Progesterone plays an important role in the menstrual cycle and in maintaining the early stages of pregnancy. It is also important for keeping oestrogen production from becoming unbalanced and stimulates the brain to produce a calming neurotransmitter. Progesterone levels begin declining when a woman is in her late 30s or early 40s, and can cause noticeable symptoms.  

What symptoms can occur during premenopause?

During premenopause, your menstrual cycle is still regular. This changes as you get older. Symptoms during premenopause can vary. Some common symptoms may include: 

During menopause, fluctuating hormones have a profound impact on women’s bodies, more so than most healthcare providers may know or realise. - Dr. E.A.H. Knauff, gynaecologist

Premenopause tips

Premenopause is the perfect time to take a good look at your lifestyle and health. According to menopause specialist Suzanne Rouhard, paying attention to your health can help to prevent or reduce symptoms during perimenopause, like osteoporosis and loss of muscle mass. Some tips: 

  • Pay attention to what you eat: Pack your diet with fruit and vegetables (fibre, vitamins and minerals in fruit can help keep hormones balanced) and protein. Limit your intake of fast carbohydrates and sugars (for more stable blood sugar levels, which is also good for hormonal health). Make sure your diet contains omega-3 (to increase healthy fats in your blood).  
  • Do strength training two times a week: As you age, you start to lose muscle mass and bone density. It’s simply a fact of life. You can slow down this process by taking care of your body. Strength training has been proven to increase bone density and keep muscles and joints healthy and strong. This is because the bones are stimulated to produce more bone tissue when they are stressed. Strength training also helps builds muscle and makes joints stronger. The added benefit is that exercise triggers dopamine release. Higher dopamine levels result in better overall mood. 
  • Make sleep your number one priority: Sleep is very important for overall health, especially for women in their 30s. Sleep plays a crucial role in all aspects of well-being, including cardiovascular and cognitive functions. According to experts, many women tend to get too little sleep during the week because of their busy lifestyles. See what you can do to improve your sleep quality
  • Make sure you get plenty of rest: In the years before and during menopause, you are more sensitive to stress. Take breaks, find enjoyable ways to relax and relieve stress (e.g., reading, going for walks, writing or drawing), or try relaxation techniques such as meditation or mindfulness. Your body needs it during this stage of life. 
  • Give up smoking and cut back on alcohol: Tobacco and alcohol use during menopause can worsen symptoms and are bad for your health in general. 
When does perimenopause begin?

The start of perimenopause varies from person to person, but in general, you could say that most women aged 45 are in perimenopause. What symptoms occur and when, if any at all, is different for each woman. Some women have severe symptoms, while others seem to have none (although this is rare). The biggest change during this period is a change in your usual menstrual pattern. Most women stop having periods around the age of 51. The day of your last menstrual period is called 'menopause'. The next stage is postmenopause. Would you like to understand your symptoms or know what stage of menopause you’re in? A menopause test can provide insight.

How do I know if I'm in perimenopause?

Do you have hormonal symptoms that come and go at different times in your cycle and do not disappear after your period? Are your symptoms gradually getting worse? Do you have irregular periods? Do you have hot flashes or vaginal dryness? Then perimenopause has probably started.

My symptoms are worse than those described here. What should I do?
