Yeast Infection: Symptoms, Causes and Online Treatment in Spain

🩺 Yeast Infection in Women: Symptoms, Causes and Online Treatment in Spain

Vaginal yeast infections (also called thrush or vaginal candidiasis) are one of the most common gynaecological conditions, affecting an estimated 75% of women at some point in their lives. According to the Mayo Clinic, yeast infections are caused by an overgrowth of the fungus Candida and are usually straightforward to treat.

If you're in Spain and experiencing symptoms of a yeast infection, you can book a discreet online consultation with UrgentDoc — our licensed doctors can assess your symptoms via video and send an e-prescription directly to your nearest pharmacy.

🔹 What Is a Vaginal Yeast Infection?

A vaginal yeast infection occurs when the fungus Candida albicans — which naturally lives in small amounts in the vagina — overgrows and causes inflammation. The vagina normally maintains a healthy balance of bacteria and yeast, but when this balance is disrupted, Candida can multiply and cause symptoms.

The NHS explains that thrush is very common and is not classified as a sexually transmitted infection, although it can occasionally be passed between partners.

🔹 Symptoms of a Yeast Infection

The Mayo Clinic lists the following common symptoms:

Intense itching or irritation of the vagina and vulva
Thick, white discharge with a cottage cheese-like texture, usually without a strong odour
Redness, swelling or soreness of the vulva
Burning sensation during urination or intercourse
Vaginal rash
Watery discharge (in some cases)

Symptoms often worsen just before menstruation or after antibiotic use. Mild cases may resolve naturally, but persistent or recurrent infections need medical attention.

When symptoms may indicate something else

Not all vaginal itching or discharge is caused by a yeast infection. Similar symptoms can result from:

Bacterial vaginosis (BV) — typically causes thin, greyish discharge with a fishy odour
Sexually transmitted infections — chlamydia, gonorrhoea and trichomoniasis can cause abnormal discharge
Contact dermatitis — reaction to soaps, lubricants or feminine products

This is why a proper medical assessment is important, especially if it's your first suspected yeast infection or if symptoms are unusual.

🔹 Common Causes and Risk Factors

Yeast infections occur when the natural balance of vaginal flora is disrupted. According to the Cleveland Clinic, key triggers include:

Antibiotic use: Antibiotics kill beneficial bacteria (lactobacilli) that normally keep Candida in check
High oestrogen levels: Pregnancy, hormonal contraception and hormone replacement therapy can raise yeast infection risk
Diabetes: Poorly controlled blood sugar creates an environment where yeast thrives
Weakened immune system: Stress, illness, immunosuppressive medications or HIV
Tight, synthetic clothing: Traps moisture in the genital area, especially in warm climates
High-sugar diet: Excess sugar can promote yeast growth
Douching: Disrupts the natural vaginal flora

Why travellers in Spain may be more susceptible

Women visiting or living in Spain may notice more frequent yeast infections due to:

Warm climate: Heat and humidity increase moisture in the genital area
Swimming and beachwear: Spending long periods in wet swimwear creates an ideal environment for yeast
Dietary changes: Different foods, increased alcohol or sugar intake during holidays
Antibiotic use: If you've recently taken antibiotics for a UTI or sore throat while travelling

🔹 How Yeast Infections Are Treated

Over-the-counter options

Mild, uncomplicated yeast infections can be treated with antifungal medications available at Spanish pharmacies (farmacias):

Topical clotrimazole cream or pessaries — applied for 1–7 days depending on the product
Topical miconazole — similar to clotrimazole, available in cream or pessary form

Prescription treatment

For moderate to severe yeast infections, or recurring cases, a doctor may prescribe:

Oral fluconazole — a single 150mg dose, effective within 1–3 days. The Mayo Clinic notes this is the most common prescription treatment
Extended antifungal courses — for recurrent infections (4+ per year), a doctor may recommend a longer course of treatment

UrgentDoc doctors can prescribe oral fluconazole during an online consultation, with the e-prescription sent directly to any Spanish pharmacy.

🔹 Yeast Infection vs Bacterial Vaginosis: How to Tell the Difference

Yeast infections and bacterial vaginosis (BV) are the two most common causes of abnormal vaginal discharge, but they require different treatments. Misdiagnosis is common — a study published in the Journal of Obstetrics and Gynaecology found that many women who self-diagnose yeast infections actually have BV.

<table style="width: 100%; border-collapse: collapse; margin: 20px 0;"> <thead> <tr style="background-color: #f8f9fa;"> <th style="border: 1px solid #dee2e6; padding: 12px; text-align: left;">Feature</th> <th style="border: 1px solid #dee2e6; padding: 12px; text-align: left;">Yeast infection</th> <th style="border: 1px solid #dee2e6; padding: 12px; text-align: left;">Bacterial vaginosis</th> </tr> </thead> <tbody> <tr> <td style="border: 1px solid #dee2e6; padding: 12px;"><strong>Discharge</strong></td> <td style="border: 1px solid #dee2e6; padding: 12px;">Thick, white, cottage cheese-like</td> <td style="border: 1px solid #dee2e6; padding: 12px;">Thin, greyish-white, watery</td> </tr> <tr style="background-color: #f8f9fa;"> <td style="border: 1px solid #dee2e6; padding: 12px;"><strong>Odour</strong></td> <td style="border: 1px solid #dee2e6; padding: 12px;">Usually none or mild</td> <td style="border: 1px solid #dee2e6; padding: 12px;">Fishy, especially after sex</td> </tr> <tr> <td style="border: 1px solid #dee2e6; padding: 12px;"><strong>Itching</strong></td> <td style="border: 1px solid #dee2e6; padding: 12px;">Intense</td> <td style="border: 1px solid #dee2e6; padding: 12px;">Mild or none</td> </tr> <tr style="background-color: #f8f9fa;"> <td style="border: 1px solid #dee2e6; padding: 12px;"><strong>Redness/swelling</strong></td> <td style="border: 1px solid #dee2e6; padding: 12px;">Common</td> <td style="border: 1px solid #dee2e6; padding: 12px;">Less common</td> </tr> <tr> <td style="border: 1px solid #dee2e6; padding: 12px;"><strong>Cause</strong></td> <td style="border: 1px solid #dee2e6; padding: 12px;">Fungal (Candida overgrowth)</td> <td style="border: 1px solid #dee2e6; padding: 12px;">Bacterial imbalance</td> </tr> <tr style="background-color: #f8f9fa;"> <td style="border: 1px solid #dee2e6; padding: 12px;"><strong>Treatment</strong></td> <td style="border: 1px solid #dee2e6; padding: 12px;">Antifungal (clotrimazole/fluconazole)</td> <td style="border: 1px solid #dee2e6; padding: 12px;">Antibiotics (metronidazole)</td> </tr> </tbody> </table>

Because these conditions require different treatments, using an antifungal for BV or an antibiotic for a yeast infection won't resolve your symptoms. If you're unsure which condition you have, an online consultation can help determine the right diagnosis and treatment.

🔹 How to Prevent Yeast Infections

The Cleveland Clinic recommends these prevention strategies:

Wear cotton underwear and avoid tight-fitting trousers, especially in warm weather
Change out of wet swimwear promptly — don't sit in a wet bikini
Avoid douching — this disrupts the natural vaginal flora
Avoid scented feminine products — scented soaps, sprays and wipes can irritate the vaginal area
Take probiotics — some evidence suggests probiotics containing lactobacillus may help maintain vaginal flora balance
Manage blood sugar — if you have diabetes, keep glucose levels well controlled
Wipe front to back after using the toilet
Change pads and tampons regularly during menstruation

🔹 When to See a Doctor

You should consult a doctor rather than self-treating if:

It's your first yeast infection — you need a proper diagnosis to rule out other conditions
Symptoms persist after 3 days of over-the-counter treatment
You have recurrent infections — 4 or more per year suggests an underlying cause that needs investigation
You're pregnant — some treatments are not safe during pregnancy
You have diabetes or a weakened immune system
Discharge has a foul odour or you have fever/pelvic pain — this may indicate a bacterial infection or STI

UrgentDoc doctors specialise in women's health and can differentiate yeast infections from bacterial vaginosis and STIs through a thorough sexual health consultation.

❓ Frequently Asked Questions

Can I treat a yeast infection while breastfeeding?

Yes, but only with doctor-approved treatments. Topical antifungals (clotrimazole) are generally safe. Oral fluconazole may pass into breast milk, so discuss this with your doctor.

Do yeast infections increase UTI risk?

Yes — the inflammation and disruption to vaginal flora can make UTIs more likely. If you develop urinary symptoms, see our guide on UTI warning signs or book a UTI consultation.

How soon after treatment can I have sex?

Wait until symptoms have fully resolved — typically 7 days after starting treatment. Sexual intercourse during an active infection can cause irritation and potentially pass the yeast to your partner.

Can men get yeast infections?

Yes, though less commonly. Male thrush typically causes redness, itching and irritation on the head of the penis. It's more common in uncircumcised men and those with diabetes.

Are yeast infections sexually transmitted?

Yeast infections are not classified as STIs, but the fungus can occasionally be passed between sexual partners. It's not necessary to treat a partner unless they have symptoms.

Can stress cause a yeast infection?

Indirectly, yes. Stress weakens the immune system and can disrupt hormonal balance, creating conditions where Candida is more likely to overgrow.
