What is a yeast infection?
Yeast infections are mainly caused by a yeast-like fungus named Candida or Monilia. This fungus is a normal resident of your body. Usually, your body’s immunity keeps this fungus under control. It causes infection if you are sick or taking any antibiotics. Your mouth, skin, nails, food pipe (esophagus), vagina, or even blood may get infected by this fungus.
What are the symptoms of a yeast infection?
- White patches in your mouth
- Difficulty in swallowing or eating
If you have esophageal (food pipe) yeast infections, you may experience:
Skin yeast infections (including nails) may cause:
If you are a woman and have vaginal yeast infections, then you may experience:
How are yeast infections diagnosed?
Your doctor will use different methods of testing yeast infections depending on the area of your infection or symptoms.
If a vaginal yeast infection is suspected by your gynecologist, then they may
- Examine your private parts
- Take vaginal fluid samples using a cotton swab
- Send the samples for further tests
- Even check your partner
If an oral yeast infection is suspected by your doctor (usually dentist), then they may
- Examine your mouth and tongue
- Scrape your mouth sore gently using a cotton swab
- Examine the sample under the microscope
In case of severe yeast infections in your esophagus, your doctor may
- Perform endoscopy (insert a tube through your mouth into your stomach and examine the esophagus)
- Perform a biopsy (take a sample from the throat for a culture test or further laboratory examination)
If you have a skin or nail yeast infection, your doctor (dermatologist) may
- Examine your skin and nails
- Scrape off a bit of your skin using a blunt-edged instrument
- Test your blood sugar level to check for diabetes
8 home remedies for yeast infections
- Vitamin C:
- Vitamin C boosts the immune system. A strong immune system can reduce the recurrence of infection. Vitamin C is rich in citric fruits, tomatoes, and may also be taken as supplements. One should avoid the local application of Vitamin C because it is acidic and sensitive to body tissue.
- Hydrogen peroxide:
- Hydrogen peroxide is an antiseptic but may not work against every species of yeast.
- Adding hydrogen peroxide to a bath or diluting in water can help with yeast growing on the genitals. Diluting (half water and half hydrogen peroxide) and applying it to the affected area can help. Remember peroxide may cause sores on the skin if used improperly.
- Probiotic suppositories and supplements:
- Probiotics can help restore the normal bacteria-yeast balance throughout the body. Probiotics are present in fermented foods like yogurt. Oral probiotics contain strains of the Lactobacillus acidophilus bacteria that can restore the balance between the digestive tract and vaginal flora. Oral supplements can take about 10 days to show effects. Vaginal suppositories have quicker results.
- Tea tree oil:
- Tea tree oil is an essential oil that helps kill fungi, bacteria, and viruses. Tea tree oil is extremely strong, hence it should be diluted with a carrier oil, such as jojoba or coconut oil, before applying to avoid irritation. A vaginal suppository containing tea tree oil should not be taken orally.
- Apple cider vinegar:
- Apple cider vinegar has many medicinal uses. Mixing half a cup of apple cider vinegar into a bathtub with warm water and soaking yourself for 20 minutes can help kill harmful bacteria and fungi, including yeast, due to the acidity of the vinegar. Apple cider vinegar can also be incorporated into the diet.
- Oregano oil:
- Oregano oil made from wild oregano or Origanum vulgare contains thymol and carvacrol, which are powerful antifungals. Mixing 3-5 drops of essential oil per ounce of carrier oil like jojoba oil and applying it to the skin can help but should not be applied close to the vagina. It can also be inhaled through a diffuser.
- Coconut oil:
- Coconut oil has several health benefits, including antibacterial and antifungal properties. Pure, organic coconut oil can be applied directly to the affected area.
- Garlic is effective against fungus and an effective Candida killer. Garlic may be added to the diet. Applying garlic over the affected area should be avoided because it causes severe burning and pain.
How to prevent yeast infections
The following tips can help reduce the number of episodes or prevent yeast infections:
- Reducing the consumption of sugar and processed foods
- Wearing loose-fitting, breathable cotton underwear and clothes
- Avoiding wearing wet clothes or bathing suits for a long time
- Avoiding antibiotics unnecessarily without a prescription

When to call a doctor
Home remedies may or may not work to treat yeast infections. Some home remedies may provide relief within a few days while some may take up to a week or longer.
It is advised to consult with a doctor before resorting to home remedies. It is important to seek medical attention if the symptoms worsen, if new symptoms appear at any point during treatment, or if the symptoms do not resolve in 1-2 weeks. Individuals with diabetes should especially visit the doctor before experimenting at home.
