Vaginitis

Vaginitis is a common condition affecting women of all ages, characterised by inflammation or infection of the vagina. It can cause a range of symptoms, including itching, burning, pain, discharge, and bad odour. Understanding the causes, symptoms, and treatment options for vaginitis is crucial for maintaining vaginal health and preventing complications.

What is Vaginitis?

Vaginitis, also known as vulvovaginitis, is an inflammation or infection of the vagina and sometimes the vulva, which is the external part of a woman's genitals. This condition can arise from a variety of underlying causes, including infections, hormonal changes, or exposure to irritants. The most prevalent forms of vaginitis include bacterial vaginosis, yeast infections, and trichomoniasis, each with different treatment approaches. Infections such as bacterial vaginosis result from imbalances in the vaginal flora, while yeast infections are caused by an overgrowth of fungi, and trichomoniasis is due to a parasitic infection. Recognising the signs and symptoms of vaginitis is essential for prompt diagnosis and treatment.

Vaginitis can be categorised into several types based on its underlying cause, including:

• Bacterial vaginosis: Bacterial vaginosis (BV) is the most common type of vaginitis, resulting from an overgrowth of normal bacteria in the vagina, particularly Gardnerella vaginalis. This overgrowth leads to an imbalance in the vaginal microbiome, disrupting the natural balance of beneficial bacteria.

• Yeast infections: Yeast infections are caused by an overgrowth of the fungus Candida albicans, which is naturally present in the vagina in small amounts. When this fungus grows excessively, it can lead to symptoms such as intense itching and a thick, white discharge resembling cottage cheese.

• Trichomoniasis: Trichomoniasis is an infection caused by the single-celled protozoan parasite Trichomonas vaginalis. This sexually transmitted infection can cause a yellow-green, frothy discharge and discomfort during urination or sexual intercourse.

• Non-infectious vaginitis: Non-infectious vaginitis is caused by irritants such as chemicals found in soaps, douches, and spermicides. These substances can lead to allergic reactions or irritation of the delicate vaginal tissues, resulting in inflammation and discomfort.

• Atrophic vaginitis: Atrophic vaginitis occurs due to decreased oestrogen levels, particularly after menopause. The lack of oestrogen causes thinning of the vaginal lining, making it more susceptible to irritation and inflammation. This type of vaginitis can cause dryness, itching, and discomfort.

Understanding the various types of vaginitis is crucial for accurate diagnosis and effective treatment.

The symptoms of vaginitis can vary depending on the underlying cause. Common symptoms include:

• Discharge: Abnormal vaginal discharge is common, with variations in consistency, colour, and odour. Bacterial vaginosis often produces a thin, greyish-white discharge with a fishy smell, while yeast infections lead to a thick, white discharge resembling cottage cheese. Trichomoniasis causes a frothy, yellow-green discharge with a strong odour.

• Itching and irritation: Persistent itching or irritation around the vaginal area is frequent, often accompanied by redness and swelling. This discomfort can range from mild to severe and can affect daily activities.

• Pain or discomfort: Vaginitis can cause pain or discomfort, particularly during intercourse or urination. This may be localised to the vaginal area or extend to surrounding regions.

• Abnormal odour: An unusual or unpleasant odour, such as a fishy smell in bacterial vaginosis, can indicate vaginitis. Yeast infections typically do not produce a strong odour.

• Burning sensation: A burning sensation during urination or sex is common due to inflammation and irritation of the vaginal tissues.

These symptoms may range from mild to severe. If you experience any of these symptoms, it's important to consult your doctor for an accurate diagnosis and appropriate treatment.

Vaginitis is an inflammation of the vagina with several potential causes, including:

• Microbial imbalances: Changes in the natural balance of vaginal bacteria can lead to vaginitis. This can occur due to antibiotic use, diabetes, or a weakened immune system.

• Sexually transmitted infections (STIs): Certain STIs, such as trichomoniasis, chlamydia, and gonorrhoea, can cause vaginitis.

• Chemical irritants: Exposure to harsh soaps, douches, spermicides, or feminine hygiene products can disrupt the delicate balance of the vagina and lead to irritation and inflammation.

• Hormonal changes: Fluctuations in hormone levels, particularly during pregnancy, menopause, or while using certain birth control methods, can increase the risk of developing vaginitis.

• Allergic reactions: Some women may experience allergic reactions to certain materials, such as latex condoms or spermicides, leading to vaginitis.

Certain factors can increase your risk of developing vaginitis, including:

• Being sexually active, especially with multiple partners or a new partner

• Using douches, vaginal sprays, or scented feminine hygiene products that can disrupt the natural balance of bacteria in the vagina

• Wearing tight, non-breathable clothing or wet swimsuits for prolonged periods

• Having uncontrolled diabetes, which can increase sugar levels in the vaginal mucous membranes and foster fungal growth

• Taking antibiotics, which can kill beneficial bacteria in the vagina and lead to yeast overgrowth

• Being pregnant, as hormonal changes can alter vaginal pH and increase susceptibility to infections

• Having a weakened immune system due to conditions like HIV/AIDS or certain medications

Recognising and addressing these risk factors can help in preventing vaginitis or reducing the frequency of recurrent episodes.

Failing to treat vaginitis promptly or effectively can lead to various complications that may impact a woman's overall health and well-being. Some potential complications of vaginitis include:

• Pelvic inflammatory disease (PID): Untreated bacterial vaginosis or STIs like trichomoniasis can ascend to the upper genital tract, causing PID. This condition can lead to chronic pelvic pain, infertility, and an increased risk of ectopic pregnancy.

• Pregnancy complications: Vaginitis during pregnancy, particularly bacterial vaginosis, has been associated with an increased risk of preterm labour, premature rupture of membranes, and low birth weight.

• Increased risk of STIs: Vaginitis can cause inflammation and micro-abrasions in the vaginal tissue, making it more susceptible to STIs like HIV, HPV, and chlamydia.

• Recurrent infections: Without proper treatment and preventive measures, vaginitis can become a recurring issue, causing discomfort and disrupting daily life.

• Psychological distress: The symptoms of vaginitis, such as itching, odour, and discharge, can cause embarrassment and psychological distress, affecting a woman's self-esteem and sexual relationships.

To avoid these complications, it is important to seek prompt medical attention if you suspect you have vaginitis.

Preventing vaginitis involves a combination of good hygiene practices and lifestyle adjustments. Here are some key preventive measures:

• Practice good hygiene: Wipe from front to back after using the toilet to avoid introducing bacteria from the anus to the vagina. Change out of wet or sweaty clothing promptly, and avoid wearing tight, non-breathable clothing for extended periods.

• Avoid irritants: Minimise the use of douches, scented tampons, and other feminine hygiene products that can disrupt the natural balance of the vagina. Use mild, unscented soaps and avoid harsh detergents or fabric softeners.

• Practice safe sex: Limit the number of sexual partners and use condoms to reduce the risk of sexually transmitted infections (STIs) that can cause vaginitis.

• Maintain a healthy lifestyle: Eat a balanced diet, stay hydrated, and manage stress to support overall immune function. If you have diabetes, work with your doctor to keep blood sugar levels under control.

• Probiotics: Eat a balanced diet rich in probiotic foods like yoghurt, kimchi, and miso, which can help promote the growth of beneficial lactobacilli bacteria in the vagina.

• Judicious antibiotic use: If prescribed antibiotics, discuss with your doctor the potential risks and benefits. Take the medication as directed, and consider using probiotics to help restore beneficial bacteria.

By incorporating these preventive strategies into daily life, women can take an active role in maintaining vaginal health and reducing the risk of vaginitis and its associated complications.

Diagnosing vaginitis typically involves a combination of medical history, physical examination, and laboratory tests. Here are the key steps in the diagnostic process:

• Medical history and physical examination: Your doctor will ask about your symptoms, medical history, and sexual practices. They will also perform a physical examination of the genital area to look for signs of inflammation, irritation, or discharge.

• Pelvic exam: A pelvic exam may be conducted to inspect the vagina and cervix for signs of infection or inflammation. During the exam, your doctor may collect a sample of vaginal discharge for further testing.

• Microscopic examination: The collected vaginal discharge may be examined under a microscope to identify the presence of yeast, bacteria, or other microorganisms that can cause vaginitis.

• pH testing: Your doctor may measure the pH level of your vaginal discharge. An elevated pH can indicate bacterial vaginosis or trichomoniasis.

• Cultures: In some cases, your doctor may send a sample of the vaginal discharge to a laboratory for culture to identify the specific type of bacteria or yeast causing the infection.

• STI testing: If a sexually transmitted infection is suspected, your doctor may recommend additional tests, such as a urine test or blood test, to screen for STIs like chlamydia, gonorrhoea, or trichomoniasis.

Accurate diagnosis is crucial for determining the appropriate treatment for vaginitis. By identifying the underlying cause of your symptoms, your doctor can recommend targeted therapies to alleviate discomfort and prevent recurrent infections.

The treatment and management of vaginitis depend on the specific type of infection and the severity of symptoms. Common treatment approaches include:

• Antifungal medications: For vaginal yeast infections, antifungal creams, suppositories, or oral medications like miconazole or fluconazole are typically prescribed.

• Antibiotics: Bacterial vaginosis is treated with oral or vaginal antibiotics, such as metronidazole or clindamycin. It is important to complete the full course of antibiotics as directed, even if symptoms improve earlier.

• Antiprotozoal medications: Trichomoniasis is treated with oral antibiotics, usually metronidazole or tinidazole. Sexual partners should also be treated to prevent reinfection.

• Hormonal therapy: In postmenopausal women with atrophic vaginitis, low-dose vaginal oestrogen creams, tablets, or rings can help restore vaginal pH and relieve symptoms.

• Home remedies: In addition to medical treatment, some home remedies may help alleviate symptoms of vaginitis. These include applying cold compresses to the vulva to reduce itching, using a moisturiser to soothe irritated skin, and taking a sitz bath to promote healing.

Living with vaginitis can be challenging, but there are several steps you can take to manage the condition and reduce the risk of recurrence. These include:

• Avoid harsh soaps, douching, and scented products.

• Use mild, unscented cleansers and wear breathable cotton underwear.

• Avoid tight-fitting clothing as it can trap moisture and promote the growth of harmful bacteria or fungi growth.

• Wipe from front to back after using the toilet to prevent the spread of bacteria from the anus to the vagina.

• Change out of wet or sweaty clothing promptly, especially after exercising.

• Avoid staying in wet swimsuits for prolonged periods.

• Use barrier methods, such as condoms, during sexual activity to reduce the risk of sexually transmitted infections that can cause vaginitis.

• Consider using a vaginal moisturiser or lubricant to alleviate dryness and discomfort, especially if you have atrophic vaginitis.

• Manage any underlying health conditions, such as diabetes or a weakened immune system, which can increase the risk of vaginitis.

By incorporating these lifestyle changes and following your doctor's advice, you can effectively manage vaginitis and improve your overall vaginal health.

You should see a doctor for vaginitis if you experience persistent or severe symptoms that do not improve with over-the-counter treatments or home remedies. Key signs to seek medical attention include intense itching, burning, or discomfort in the vaginal area, as well as an abnormal discharge that may be unusual in colour, odour, or consistency. Additionally, if you experience pain during intercourse, unusual bleeding, or symptoms that interfere with your daily activities, a medical evaluation is warranted. It is also important to consult a doctor if you are pregnant, have recurrent vaginitis, or if your symptoms are accompanied by fever or general malaise. A proper diagnosis by a doctor is essential for determining the exact cause of your symptoms and receiving appropriate treatment.
