Vaginal discharge change

Overview

Vaginal discharge is fluid that comes from the vagina. It is normal and healthy. A change in how the discharge looks, smells, or feels can signal an infection or other health issue. This article explains what might cause a change and when to see a doctor.

Yes, almost everyone with a vagina has some discharge. Changes are very common and often not a cause for worry.

Anyone with a vagina can experience changes in discharge, especially during their reproductive years. Changes are also common during pregnancy, after menopause, or when using certain medications.

Symptoms

Common symptoms

• Discharge that is thicker, clumpy, or more watery than usual
• Change in color (yellow, green, grey, or brown)
• Strong or fishy smell
• Itching or irritation around the vulva or vagina
• Pain or burning when you urinate
• Pain during sex

Symptoms in children

• Redness or itching around the vaginal area
• Discharge that is yellowish or has a bad smell
• Pain when passing urine

Symptoms in older adults

• Discharge that is watery or thin
• Dryness or irritation (especially after menopause)
• Bleeding after sex or between periods (if still having periods)
• Itching or burning

Causes

Main causes

• Infections – yeast infections (thrush), bacterial vaginosis, and sexually transmitted infections like chlamydia, gonorrhoea, or trichomoniasis
• Hormonal changes – from your monthly cycle, pregnancy, breastfeeding, or menopause
• Medications – antibiotics can upset the normal balance of bacteria and yeast
• Irritation – from douching, scented soaps, bubble bath, or wearing tight non-cotton underwear
• Allergic reactions – to latex condoms, spermicide, or laundry detergents
• Retained foreign object – like a forgotten tampon (rare but possible)

Risk factors

• Having a new sexual partner or multiple partners
• Using antibiotics recently
• Being pregnant or just after childbirth
• Having diabetes (especially if blood sugar is not well controlled)
• Using douching or scented feminine hygiene products
• Wearing tight, non-breathable clothing for long periods

When to see a doctor

See a doctor urgently if:

• Sudden, severe pelvic pain with discharge
• Heavy bleeding along with discharge
• Fever and chills with discharge

Book a routine appointment if:

• Change in discharge that lasts more than a few days
• Itching, burning, or irritation that does not improve with home care
• Discharge after having unprotected sex
• Any bleeding after sex or between periods

Diagnosis

Your doctor or nurse will ask about your symptoms, sexual history, and any medications you take. They may examine your vagina and take a small sample of discharge.

Tests that may be done

• Swab test – a cotton swab is used to collect a sample of discharge from the vagina or cervix
• pH test – a strip of paper is touched to the discharge to measure acidity (some infections cause high pH)
• Urine test – if a sexually transmitted infection is suspected
• Blood test – in some cases, to check for infections or hormonal causes

What to expect at your appointment

The tests are quick and usually painless. You might feel a slight pressure or tickling sensation. Results may take a few minutes (like for a pH test) or a few days (for lab swabs). Your doctor will explain the results and any treatment you need.

Treatment

Treatment depends on the cause. Many infections are easily treated with medication from your doctor or pharmacist. Sometimes no treatment is needed if the discharge is normal.

Self-care at home

• Wash your genital area gently with plain warm water (no soap or shower gel)
• Avoid douching or using feminine sprays, deodorants, or wipes
• Wear cotton underwear and loose-fitting clothing
• Change out of wet clothes (like swimsuits or gym wear) quickly
• For mild itching, try a plain, unscented moisturiser or cool compress
• If you think it might be thrush, you can ask your pharmacist about over-the-counter treatments

Medical treatments

Your doctor may prescribe antifungal creams, suppositories, or oral tablets for yeast infections. For bacterial vaginosis or sexually transmitted infections, they may prescribe antibiotics (tablets or creams). Always finish the full course, even if symptoms go away. Never share your medication.

When is surgery considered?

Surgery is not a treatment for a change in vaginal discharge. In very rare cases, surgery might be needed for an underlying cause like a retained foreign object or a structural issue.

Living with this condition

Most causes of changed discharge are short-term and clear up with treatment. You can continue your normal activities, including sex, as long as you and your partner do not have symptoms. If you are being treated for an infection, wait until the treatment is complete and symptoms have gone before having sex again.

Lifestyle tips

• Keep your genital area clean and dry
• Use unscented period products (pads, liners, tampons)
• Use condoms to reduce the risk of sexually transmitted infections
• Avoid sharing towels or washcloths

Diet and exercise

Eating a balanced diet with plenty of fruits and vegetables supports your immune system. Some people find that eating yoghurt with live cultures (probiotics) helps maintain healthy vaginal bacteria. Staying active helps overall health, but avoid sitting in sweaty clothes for long periods.

Mental health and emotional wellbeing

Worrying about discharge changes or infections can cause anxiety and affect your confidence or relationships. It is normal to feel embarrassed, but remember that these problems are very common and treatable. If you feel stressed or low, talk to your doctor or a counsellor. For urgent emotional support, contact a crisis helpline in your area.

Prevention

Not always, but you can lower your risk: avoid douching and scented products, use condoms, wipe from front to back after using the toilet, and wear breathable underwear. Keeping your blood sugar under control if you have diabetes also helps.

Vaccines

The HPV vaccine protects against certain viruses that can cause genital warts and changes in discharge. Ask your doctor if you are eligible.

Screening programmes

If you are sexually active and under 25, the NHS offers chlamydia screening. Regular cervical screening (smear test) checks for changes that could lead to cancer. These tests do not detect all causes of discharge, but they are important for overall health.

Complications

If left untreated

• Pelvic inflammatory disease (PID) – an infection that can spread to the womb, fallopian tubes, and ovaries, causing long-term pain and fertility problems
• Increased risk of getting or passing on sexually transmitted infections
• In pregnancy, some infections can cause premature labour or infection in the baby after birth
• Chronic itching or skin changes from ongoing irritation

Long-term outlook

With proper treatment, most vaginal discharge changes clear up completely and do not cause long-term problems. Even sexually transmitted infections are usually curable with antibiotics. If you have repeated episodes, your doctor can help find the cause and prevent them from coming back.
