Have you ever wondered why your vaginal health changes as you age? Let’s dive in to discuss this and discuss why these changes are completely normal.

One of the biggest misconceptions I hear as an OB/GYN is: “Something feels different…is something wrong with me?” The truth is, your vaginal health is supposed to change over time. Just like your skin, metabolism, and hormones evolve with age, so does your vagina and vulva. Understanding those changes can help you feel empowered instead of embarrassed.

The Hormonal Sweet Spot (Age 20-39)

During your reproductive years in the second and third decades of life, estrogen levels are typically higher and more stable. Estrogen helps keep the vaginal tissue thick and elastic, naturally lubricated, balanced in pH and essentially more protected against irritation and infection.

This season is usually when vaginal tissue feels healthiest and most resilient. But even during this phase, things like stress, birth control, pregnancy, antibiotics, sweating, tight clothing, and certain soaps can still disrupt your vaginal balance.

Common concerns during this stage may include:

• Yeast infections
• Bacterial vaginosis (BV)
• Odor changes after workouts or sex
• Irritation from shaving or products
• Dryness from hormonal birth control

The Sacred Shift (Pregnancy/Postpartum)

Pregnancy and postpartum bring dramatic hormonal shifts that can affect vaginal health in ways many women aren’t prepared for. During pregnancy, increased blood flow and discharge are common. After delivery, especially while breastfeeding, estrogen levels can drop significantly, leading to vaginal dryness, pain with intercourse, burning or irritation or increased sensitivity.

Many women are shocked to experience menopausal-type symptoms in their 20s or 30s postpartum, but it’s more common than people realize.

Perimenopausal Hormonal Awakening (Age 36-50)

Perimenopause can begin years before menopause officially starts. Typically in your late 30s or early 40s. Hormone fluctuations during this stage can cause irregular periods, vaginal dryness, lower libido, increased vaginal irritation, changes in vaginal discharge, and recurrent UTIs or infections. These changes happen due to declining estrogen levels, which affects the vaginal tissue and microbiome.

The vaginal pH also becomes less acidic with age, making some women more prone to irritation and infections.

The Golden Era (Age 51 and beyond)

After menopause, typically in your 50s and beyond, estrogen levels decrease significantly. This can lead to a condition called genitourinary syndrome of menopause (GSM), which affects many women but is often under-discussed.

Symptoms of GSM can include:

• Vaginal dryness
• Burning
• Itching
• Pain during intimacy
• Vaginal thinning
• Urinary urgency or leakage
• Frequent UTIs

Many women think these symptoms are something they just have to “deal with,” but there are over the counter and prescribed treatment options available. So please do not hesitate to reach out to your physician.
 

What Doesn’t Help Your Vaginal Health

Unfortunately, social media has normalized a lot of harmful vaginal advice. Your vagina does not need:

• Detoxes
• Steaming
• Harsh scrubs
• Washes that are heavily scented and not designed for the vulvar area
• DIY home remedies from TikTok

Many of these can actually disrupt your vaginal microbiome and worsen irritation.
 

Be Mindful of Overuse of Antibiotics

Antibiotics can be lifesaving when medically necessary, but they can also disrupt healthy vaginal bacteria. Some women notice recurrent yeast infections after antibiotic use because the protective or “good bacteria” (lactobacilli) in the vagina are also temporarily reduced after antibiotics.

Things to keep in mind with using antibiotics:

• Only use them when prescribed by a healthcare professional and medically indicated
• Complete your full course as directed unless instructed otherwise by your physician
• Stay hydrated
• Discuss prevention strategies with your OBGYN prior to starting antibiotics
• Contact your OBGYN if symptoms develop after antibiotic use

What Daily Habits Actually Support Vaginal Health

Healthy vaginal care is usually simple. Your vaginal microbiome is a delicate ecosystem that is made up of healthy bacteria. This bacteria is primarily lactobacilli that help to maintain a well balanced pH and protect against infections. When that balance is disrupted, it can increase the risk of issues like BV, yeast infections, odor changes, and irritation.

The good news is that small daily habits can make a significant difference in maintaining your vaginal health over time. Here’s what I recommend most often:

• Use gentle products, or products designed for the vaginal/vulvar area
• Use warm water
• Avoid overwashing
• Wear breathable underwear especially during workouts and hot weather (ie. cotton)
• Change out of sweaty clothes promptly
• Avoid sitting in wet swimsuits for extended periods of time
• Stay hydrated
• Use lubrication when needed
• Don’t ignore persistent symptoms
• Stop normalizing discomfort
• Manage stress levels
• Get adequate sleep
• Eat a balanced diet rich in nutrients

When to See Your OB/GYN

You should see a physician if you are having any of the following symptoms:

• Persistent itching or burning
• Pain with sex
• Bleeding after intercourse
• Strong odor
• Recurrent infections
• Significant dryness
• Pelvic pain or pressure

Aging is normal. Suffering in silence is not. Your vaginal health deserves attention at every stage of life; not just during pregnancy or annual exams. Because women deserve to understand their bodies and feel comfortable in them, not feel ashamed of them.
