Why dryness happens after birth

Pregnancy floods the body with high levels of oestrogen, which keeps the vaginal tissue thick, lubricated, and elastic. After delivery, oestrogen drops sharply and stays low while you're breastfeeding. The hormonal environment temporarily resembles menopause: low oestrogen, dry mucosal tissue, reduced lubrication, sometimes thinning of the vaginal walls.²

Three things drive it:

• Sudden oestrogen drop after placenta delivery. Levels fall by more than 90% within days of birth.
• Prolactin (the breastfeeding hormone) suppresses oestrogen for as long as you're feeding regularly.³
• Disrupted sleep, dehydration, and stress all compound the picture.

This is a normal biological response, not a sign that anything is wrong. It is also temporary in most women, resolving once breastfeeding stops or significantly reduces.

02

What it typically feels like

The most common patterns:

• Discomfort or pain during sex, particularly the first few times after the postnatal check
• A general dryness sensation even when not aroused
• Stinging when urinating or after sex
• Sensitivity or rawness of the vulva
• Reduced natural lubrication during arousal
• Tearing or splitting of skin in severe cases, particularly at the perineum

Some women also describe a loss of sensation, lower libido, or anxiety about sex. All of these can travel together. The combination is normal, biological, and treatable.

03

How long it lasts

The timeline varies, but the common pattern:

• 0–6 weeks postpartum: healing phase, intercourse not yet resumed for most women
• 6–12 weeks postpartum: the postnatal check happens, sex often resumes. Dryness is at its most noticeable.
• 3–6 months postpartum: dryness persists if breastfeeding is the main feeding method
• After weaning: oestrogen typically returns within 2–3 months of weaning, and lubrication returns with it

If dryness continues more than 3 months after weaning, see your GP. This sometimes points to other causes that need assessment (thyroid changes, perimenopause if you're older, scarring from a difficult delivery).

04

Treatments safe in breastfeeding

Most women want options that don't interfere with breastfeeding. The good news: most non-hormonal treatments work well, and even some hormonal options are safe.

Lubricants

The first-line approach when discomfort is mainly during sex. Use generously.

• Water-based or silicone-based lubricants are safe in breastfeeding and don't interact with anything
• Avoid glycerin-based or warming lubricants which can irritate sensitive postpartum tissue
• Avoid oil-based lubricants if using barrier contraception (latex condoms)

Vaginal moisturisers

Used 2–3 times a week regardless of sex, to hydrate the vaginal walls daily.

• Hyaluronic acid moisturisers (vaginal gels or ovules) are safe in breastfeeding and well evidenced for non-hormonal dryness relief.⁴ For the broader evidence picture, read Hyaluronic Acid for Vaginal Dryness.
• Polycarbophil-based moisturisers (Replens) are also safe and effective.

Low-dose vaginal oestrogen

For women with significant dryness who are weeks past the immediate postnatal period and not improving with lubricants and moisturisers, low-dose vaginal oestrogen is generally considered safe in breastfeeding.⁵ Local oestrogen acts on local tissue and does not raise systemic oestrogen levels meaningfully, which means it does not affect milk supply in most women. It is sometimes prescribed for postpartum women with persistent symptoms after a discussion with the GP.

Pelvic floor physiotherapy

A women's-health physiotherapist can assess for pelvic floor tension or scarring that may be contributing to dryness or pain. This is especially valuable after a difficult delivery, instrumental birth, or perineal tear.

Lifestyle support

• Hydration: breastfeeding is dehydrating. Drink to thirst, plus extra
• Sleep where you can: poor sleep worsens dryness through the cortisol pathway
• Time: simply not rushing back to sex on a schedule. The 6-week postnatal check is medical clearance, not a deadline

05

When sex starts hurting

Pain during sex (dyspareunia) is one of the most common postpartum issues and one of the most underreported. Common contributors:

• Vaginal dryness from low oestrogen
• Perineal scar tissue from a tear or episiotomy
• Pelvic floor tension from labour or from anticipating pain
• Healing trauma from a difficult or instrumental delivery
• Caesarean recovery which can also produce pelvic discomfort, even though the vagina itself wasn't involved

A short list of practical things that help while you're waiting for treatments to work:

• Use generous lubricant. More than feels reasonable. It helps.
• Take the time to feel aroused before penetration. Natural lubrication is reduced but not gone.
• Try positions where you can control depth and pace (woman on top, side-lying).
• Talk to your partner. Most postpartum partners want to know what helps; very few will know to ask in detail.
• Stop if it hurts. Pushing through pain creates avoidance and pelvic floor guarding that compound over time.

If pain is persistent, a women's health physiotherapist plus a GP visit is the right next step.

06

When to see your GP

Most postpartum vaginal dryness improves with lubricants and moisturisers and time. See your GP if any of these apply:

• Pain during sex that hasn't improved with lubricants and moisturisers after 4–6 weeks of consistent use
• Bleeding during or after sex
• Persistent burning or stinging when urinating
• Visible tissue changes (whiteness, irritation, splitting)
• Recurrent UTIs
• Symptoms continuing more than 3 months after weaning

What to ask for

• A vaginal examination to check for atrophy, scarring, or infection
• A pelvic floor physiotherapy referral if pain is prominent
• A discussion of vaginal oestrogen if non-hormonal options haven't worked
• A swab to rule out infection if there's any discharge change or itching

07

What you can do this week

A few things that often produce visible improvement within 2–4 weeks:

• Buy a proper vaginal moisturiser (hyaluronic acid or Replens) and start using it 2–3 times a week
• Switch to a non-irritating lubricant (water-based or silicone-based, no glycerin or fragrance)
• Drink an extra litre of water per day, particularly when breastfeeding heavily
• Schedule sex when you're rested, not when you're exhausted. Counterintuitive but it matters
• Book a women's health physio appointment if you haven't had one since the birth. Most Australian women are entitled to a Medicare-rebated session and don't know
• Talk to your partner about what you're experiencing. They almost certainly want to help

08

Why this matters

Postpartum vaginal dryness is one of the most common physical changes after birth, and one of the most poorly addressed. It is almost never raised in the standard 6-week check, and women often don't know whether to bring it up or whether what they're feeling is "normal."

It is normal, it is biological, and it is treatable. The women who use lubricants and moisturisers actively, and who get a women's health physio appointment if pain is involved, almost always describe substantial improvement within 4–8 weeks. The women who don't talk about it often go months or years quietly avoiding sex and assuming something is wrong with them.

You do not have to wait for breastfeeding to finish before treating this. The treatments are safe, the conversations are short, and the relief is usually quick.
