A vaginal yeast infection usually lasts 3 to 7 days when treated with antifungal medicine. Many people start to feel better within 24 to 48 hours, with less itching and irritation.
If a yeast infection is not treated, it can last for weeks or longer and may become more uncomfortable. Sometimes symptoms may get better on their own, but this cannot be predicted. Untreated infections are more likely to recur or worsen.
How long a yeast infection lasts depends on:
- How bad the infection is.
- How soon will treatment start?
- If the infection keeps coming back.
- Health factors such as hormone changes or diabetes.
Mild infections usually clear up faster. More serious or recurring infections may require longer treatment and may take up to two weeks to fully resolve.
What is a vaginal yeast infection?
A vaginal yeast infection, also called vaginal thrush, is a common fungal infection. It happens when too much Candida yeast grows in the vagina.
Small amounts of this yeast normally live in the vagina and do not cause any problems. A yeast infection starts when the natural balance of healthy bacteria and yeast is disturbed. This allows the yeast to grow too much.
This can happen when the good bacteria, called Lactobacillus, decrease. When this happens, the vagina can become irritated and swollen, which causes the usual symptoms of a yeast infection.
Vaginal yeast infections are not sexually transmitted infections, but sexual activity can sometimes trigger symptoms in people who get them easily.
Most adults with vaginas will have at least one yeast infection in their lives. Some people may get them more often and have repeated infections.
Common symptoms of a yeast infection
Yeast infection symptoms usually affect the vagina and vulva. They can be mild or more serious. The most common symptoms are:
- Strong itching or irritation around the vagina and vulva.
- Thick, white vaginal discharge that looks like cottage cheese.
- Redness and swelling of the vulva.
- Burning or pain when passing urine.
- Pain or discomfort during sex.
- Soreness or sensitivity around the vaginal opening.
The discharge from a yeast infection usually has no smell or only a very mild smell. This helps tell it apart from other conditions, such as bacterial vaginosis, which often causes a strong fishy smell.
Symptoms can start slowly or appear suddenly. If the infection is not treated, symptoms can get worse over time.
The severity of symptoms does not always reflect how long the infection has been present. This is why getting the right diagnosis and treatment is important.
What causes yeast infections
A yeast infection occurs when the natural balance of germs in the vagina changes, allowing too much Candida yeast to grow.
Many medical, hormonal, and lifestyle factors can increase the likelihood of a yeast infection.
Medical and hormonal causes
Some health conditions and treatments can increase the risk, including:
- Taking antibiotics, which can reduce healthy bacteria that keep yeast under control.
- Hormone changes during the menstrual cycle.
- Pregnancy, because oestrogen levels are higher.
- Diabetes, especially if blood sugar is not well controlled.
- A weak immune system caused by illness or certain medicines.
These changes make it easier for yeast to grow too much.
Lifestyle and hygiene causes
Daily habits can also play a role, such as:
- Wearing tight or non-breathable clothes that trap heat and moisture.
- Staying in wet or sweaty clothes for a long time.
- Using scented soaps, vaginal sprays, or douches.
- Wearing underwear made from synthetic materials that do not let air through.
Yeast grows best in warm and moist places. This is why good hygiene and wearing breathable clothing can help prevent infections.
How long does a yeast infection last
How long a yeast infection lasts depends on how bad it is and whether treatment is started. Most people feel better faster when they use antifungal medicine early.
With treatment
When treated with antifungal medicine, many yeast infections start to improve within 24 to 48 hours. Itching and burning usually get better first. Redness and discharge improve more slowly.
For most mild to moderate infections:
- Symptoms improve within a few days.
- The infection usually clears within 7 to 14 days.
- It is important to finish the full course of treatment so the infection does not come back
More serious or recurring yeast infections may require longer treatment and medical help.
Without treatment
Without antifungal treatment, a yeast infection can persist for much longer and become more uncomfortable. Some mild infections may go away on their own, but this cannot be predicted.
Without treatment:
- Symptoms may last for weeks or longer.
- The infection can worsen, causing increased redness, swelling, and soreness.
- There is a higher chance the infection will return.
Leaving a yeast infection untreated can also make it harder to tell it apart from other vaginal problems that require different treatment.

How Long Do Symptoms Take To Improve
Most people begin to notice relief from yeast infection symptoms within 24 to 48 hours after starting antifungal treatment. Improvement usually happens gradually rather than all at once.
- Itching and irritation often improve first, sometimes within the first day of treatment.
- Burning during urination or sex usually eases as inflammation decreases.
- Vaginal discharge may take several days to return to normal.
- Redness and swelling can take up to a week to fully settle.
Even if symptoms improve quickly, it is important to complete the full course of treatment as directed. Stopping medication too early can allow the yeast infection to return and may lead to recurrent symptoms.
If there is no improvement after several days of treatment, or if symptoms become worse, medical advice should be sought to confirm the diagnosis and rule out other conditions that can cause similar symptoms.
Can A Yeast Infection Go Away On Its Own?
Sometimesa mild yeast infection may resolve on its own. This happens when the body restores a healthy balance of bacteria and yeast on its own. However, there is no way to know for sure if it will go away or get worse.
Without treatment:
- Symptoms may last much longer.
- Discomfort can increase over time.
- The infection is more likely to come back.
- It can be confused with other vaginal problems that need different treatment.
Yeast infection symptoms can be similar to bacterial vaginosis and some sexually transmitted infections. Treating yourself without checking first can delay getting the right diagnosis.
For most people, antifungal medicine is the safest and quickest way to feel better and prevent problems. It is important to get medical advice if this is your first yeast infection or if symptoms do not improve after a few days.
How Yeast Infections Are Diagnosed
A yeast infection is usually diagnosed by looking at symptoms and asking about your medical history. A healthcare professional may ask about:
- Vaginal discharge.
- Itching or pain.
- Recent use of antibiotics.
- Hormone changes.
Sometimes, a vaginal swab is taken to check for Candida yeast. This is more likely if:
- Symptoms are very strong.
- The infection keeps coming back.
- Treatment has not worked.
- It is not clear what is causing the symptoms.
Trying to diagnose yourself is not always accurate because different vaginal problems can have the same symptoms. Conditions like bacterial vaginosis and some sexually transmitted infections also cause itching and unusual discharge, but they need different treatments.
Getting the right diagnosis helps make sure the correct antifungal medicine is used and avoids treatment that does not work.
Treatment Options For Yeast Infections
Yeast infections are treated with antifungal medicine that prevents Candida from growing. The type of treatment depends on how bad the infection is and if it keeps coming back.
Over-the-counter treatments
Mild yeast infections can often be treated with over-the-counter medicine. These usually come as creams or vaginal pessaries and are used for a few days.
Common treatments include:
- Clotrimazole, used as a cream or pessary
- Miconazole, used as a vaginal cream
These medicines are put directly onto the affected area. They help reduce itching, discharge, and irritation over time.
Prescription treatments
A stronger treatment may be needed for more serious or recurrent yeast infections, or if pharmacy treatments do not work.
The most common prescription medicine is:
- Fluconazole, taken as a tablet by mouth
For simple infections, one tablet is often enough. For infections that last longer or keep coming back, a longer course may be needed.
A healthcare professional will choose the best treatment based on your symptoms and medical history.

Why Do Some Yeast Infections Last Longer
Some yeast infections take longer to go away, even with treatment. This can happen when certain health or lifestyle factors make it harder for the body to heal or stop the yeast from growing.
Common reasons a yeast infection may last longer include:
- Late treatment, which allows symptoms to become worse before medicine is started.
- Repeated infections, which may need longer or repeated treatment.
- Uncontrolled diabetes because high blood sugar helps yeast grow.
- Hormone changes, such as during pregnancy or from hormonal contraception.
- A weak immune system, which makes it harder for the body to fight the infection.
- Stopping treatment too early, before the infection is fully gone.
Sometimes, the type of yeast causing the infection does not respond well to usual antifungal medicine. This can also slow recovery.
If symptoms persist after treatment, it is important to be rechecked to confirm the diagnosis and adjust treatment if needed.
Conditions That Can Be Mistaken For A Yeast Infection
Some health problems can cause symptoms that mimic those of a yeast infection. This is why getting the right diagnosis is important, especially if antifungal medicine does not help.
Common conditions with similar symptoms include:
- Bacterial vaginosis (BV): Thin grey or white discharge with a strong fishy smell.
- Urinary tract infection (UTI): Burning when passing urine and needing to go to the toilet often, with little or no vaginal discharge.
- Sexually transmitted infections (STIs): Unusual discharge, sores, rashes, or bleeding between periods.
- Skin irritation or contact dermatitis: Itching or redness caused by soaps, detergents, or hygiene products.
Unlike yeast infections, bacterial vaginosis is caused by bacteria, not fungi. STIs can also cause itching and discomfort, but often come with other symptoms such as pain, sores, or bleeding.
If symptoms do not improve after antifungal treatment, or if new symptoms appear, it is important to seek medical advice to identify the underlying cause and receive the appropriate treatment.
When to see a doctor
You should get medical advice if you think you have a yeast infection, but the symptoms do not get better, or if this is the first time you have had these symptoms. A doctor or nurse can ensure you receive the right diagnosis and treatment.
You should see a doctor if:
- Symptoms persist for more than 7 days even after treatment.
- Symptoms are very bad, such as severe pain, swelling, or cracked skin.
- This is your first suspected yeast infection.
- You get yeast infections often.
- Symptoms come back soon after finishing treatment.
- You are pregnant.
- You have a fever, pelvic pain, or unusual bleeding.
Because yeast infection symptoms can be similar to those of other vaginal problems, seeing a healthcare professional helps identify the true cause and prevent problems from the wrong treatment.
How To Prevent Future Yeast Infections
Preventing yeast infections means keeping the vagina healthy and avoiding things that help yeast grow. Small daily habits can make a big difference.
Helpful tips include:
- Wear cotton underwear and avoid tight clothes that trap moisture.
- Change out of wet or sweaty clothes as soon as possible.
- Do not use scented soaps, vaginal sprays, or douches.
- Use mild, fragrance-free hygiene products.
- Always finish the full course of antifungal treatment.
- Keep health conditions like diabetes under control.
- Wipe from front to back after using the toilet.
If you get yeast infections often, a healthcare professional may suggest extra ways to help prevent them based on your health needs.
Good hygiene and treating symptoms early can help reduce discomfort and lower the chance of getting another infection.
