The vagina is an internal organ with a complex ecosystem, influenced by circulating hormone levels which change during the menstrual cycle, pregnancy, breastfeeding and menopause.

Around and after menopause, there are normal changes in the growth and function of vaginal cells, as well as the vagina’s microbiome (groups of bacteria living in the vagina). Many women won’t notice these changes. They don’t usually cause symptoms or concern, but if they do, symptoms can usually be managed.

Here’s what happens to your vagina as you age, whether you notice or not.

Let’s clear up the terminology

We’re focusing on the vagina, the muscular tube that goes from the external genitalia (the vulva), past the cervix, to the womb (uterus). Sometimes the word “vagina” is used to include the external genitalia. However, these are different organs and play different roles in women’s health.

What happens to the vagina as you age?

Like many other organs in the body, the vagina is sensitive to female sex steroid hormones (hormones) that change around puberty, pregnancy and menopause.

Menopause is associated with a drop in circulating oestrogen concentrations and the hormone progesterone is no longer produced. The changes in hormones affect the vagina and its ecosystem. Effects may include:

• less vaginal secretions, potentially leading to dryness
• less growth of vagina surface cells resulting in a thinned lining
• alteration to the support structure (connective tissue) around the vagina leading to less elasticity and more narrowing
• fewer blood vessels around the vagina, which may explain less blood flow after menopause
• a shift in the type and balance of bacteria, which can change vaginal acidity, from more acidic to more alkaline.

What symptoms can I expect?

Many women do not notice any bothersome vaginal changes as they age. There’s also little evidence many of these changes cause vaginal symptoms. For example, there is no direct evidence these changes cause vaginal infection or bleeding in menopausal women.

Some women notice vaginal dryness after menopause, which may be linked to less vaginal secretions. This may lead to pain and discomfort during sex. But it’s not clear how much of this dryness is due to menopause, as younger women also commonly report it. In one study, 47% of sexually active postmenopausal women reported vaginal dryness, as did around 20% of premenopausal women.

Other organs close to the vagina, such as the bladder and urethra, are also affected by the change in hormone levels after menopause. Some women experience recurrent urinary tract infections, which may cause pain (including pain to the side of the body) and irritation. So their symptoms are in fact not coming from the vagina itself but relate to changes in the urinary tract.

Not everyone has the same experience

Women vary in whether they notice vaginal changes and whether they are bothered by these to the same extent. For example, women with vaginal dryness who are not sexually active may not notice the change in vaginal secretions after menopause. However, some women notice severe dryness that affects their daily function and activities.

In fact, researchers globally are taking more notice of women’s experiences of menopause to inform future research. This includes prioritising symptoms that matter to women the most, such as vaginal dryness, discomfort, irritation and pain during sex.

If symptoms bother you

Symptoms such as dryness, irritation, or pain during sex can usually be effectively managed. Lubricants may reduce pain during sex. Vaginal moisturisers may reduce dryness. Both are available over-the-counter at your local pharmacy.

While there are many small clinical trials of individual products, these studies lack the power to demonstrate if they are really effective in improving vaginal symptoms.

In contrast, there is robust evidence that vaginal oestrogen is effective in treating vaginal dryness and reducing pain during sex. It also reduces your chance of recurrent urinary tract infections. You can talk to your doctor about a prescription.

Vaginal oestrogen is usually inserted using an applicator, two to three times a week. Very little is absorbed into the blood stream, it is generally safe but longer-term trials are required to confirm safety in long-term use beyond a year.

Women with a history of breast cancer should see their oncologist to discuss using oestrogen as it may not be suitable for them.

Are there other treatments?

New treatments for vaginal dryness are under investigation. One avenue relates to our growing understanding of how the vaginal microbiome adapts and modifies around changes in circulating and local concentrations of hormones.

For example, a small number of reports show that combining vaginal probiotics with low-dose vaginal oestrogen can improve vaginal symptoms. But more evidence is needed before this is recommended.

Where to from here?

The normal ageing process, as well as menopause, both affect the vagina as we age.

Most women do not have troublesome vaginal symptoms during and after menopause, but for some, these may cause discomfort or distress.

While hormonal treatments such as vaginal oestrogen are available, there is a pressing need for more non-hormonal treatments.

Exercise training while wearing a weighted vest is undergoing somewhat of a renaissance. Social media posts and trainers are promoting them as a potential strategy for improving fitness and health.

Exercising with additional weight attached to the body is nothing new. This idea has been used with soldiers for many centuries if not millennia – think long hikes with a heavy pack.

The modern weighted vest comes in a range of designs that are more comfortable and can be adjusted in terms of the weight added. But could one be helpful for you?

What the research says

One of the earliest research studies, reported in 1993, followed 36 older people wearing weighted vests during a weekly exercise class and at home over a 20-week period. Wear was associated with improvements in bone health, pain and physical function.

Since then, dozens of papers have evaluated the exercise effects of wearing a weighted vest, reporting a range of benefits.

Not surprisingly, exercise with a weighted vest increases physiological stress – or how hard the body has to work – as shown by increased oxygen uptake, heart rate, carbohydrate utilisation and energy expenditure.

Adding weight equal to 10% of body weight is effective. But it doesn’t appear the body works significantly harder when wearing 5% extra weight compared to body weight alone.

Does more load mean greater injury risk?

A small 2021 study suggested additional weights don’t alter the biomechanics of walking or running. These are important considerations for lower-limb injury risk.

The safety considerations of exercising with weighted vests have also been reported in a biomechanical study of treadmill running with added weight of 1% to 10% of body weight.

While physiological demand (indicated by heart rate) was higher with additional weight and the muscular forces greater, running motion was not negatively affected.

To date no research studies have reported increased injuries due to wearing weighted vests for recreational exercise. However a 2018 clinical study on weight loss in people with obesity found back pain in 25% of those wearing such vests. Whether this can be translated to recreational use in people who don’t have obesity is difficult to say. As always, if pain or discomfort is experienced then you should reduce the weight or stop vest training.

Better for weight loss or bone health?

While wearing a weighted vest increases the energy expenditure of aerobic and resistance exercise, research to show it leads to greater fat loss or retaining muscle mass is somewhat inconclusive.

One older study investigated treadmill walking for 30 minutes, three times a week in postmenopausal women with osteoporosis. The researchers found greater fat loss and muscle gain in the participants who wore a weighted vest (at 4–8% body weight). But subsequent research in obese older adults could not show greater fat loss in participants who wore weighted vests for an average of 6.7 hours per day.

There has been considerable interest in the use of weighted vests to improve bone health in older people. One 2003 study reported significant improvements in bone density in a group of older women over 32 weeks of weighted vest walking and strength training compared to a sedentary control group.

But a 2012 study found no difference in bone metabolism between groups of postmenopausal women with osteoporosis walking on a treadmill with or without a weighted vest.

Making progress

As with any exercise, there is a risk of injury if it is not done correctly. But the risk of weighted vest training appears low and can be managed with appropriate exercise progression and technique.

If you are new to training, then the priority should be to simply start exercising and not complicate it with wearing a weighted vest. The use of body weight alone will be sufficient to get you on the path to considerable gains in fitness.

Once you have a good foundation of strength, aerobic fitness and resilience for muscles, joints and bones, using a weighted vest could provide greater loading intensity as well as variation.

It is important to start with a lighter weight (such as 5% bodyweight) and build to no more than 10% body weight for ground impact exercises such as running, jogging or walking.

For resistance training such as squats, push-ups or chin-ups, progression can be achieved by increasing loads and adjusting the number of repetitions for each set to around 10 to 15. So, heavier loads but fewer repetitions, then building up to increase the load over time.

While weighted vests can be used for resistance training, it is probably easier and more convenient to use barbells, dumbbells, kettle bells or weighted bags.

The bottom line

Weighted vest training is just one tool in an absolute plethora of equipment, techniques and systems. Yes, walking or jogging with around 10% extra body weight increases energy expenditure and intensity. But training for a little bit longer or at a higher intensity can achieve similar results.

There may be benefits for bone health in wearing a weighted vest during ground-based exercise such as walking or jogging. But similar or greater stimulus to bone growth can be achieved by resistance training or even the introduction of impact training such as hopping, skipping or bounding.

Exercising with a weighted vest likely won’t increase your injury risk. But it must be approached intelligently considering fitness level, existing and previous injuries, and appropriate progression for intensity and repetition.
