This is an overview of 10 common vaginal problems. But, let’s start with a definition.
What is the Vagina?
The vagina is an internal, muscular canal that extends from the vulva (the external genitalia) to the cervix (the neck of the uterus). It is entirely distinct from the vulva.
The vagina plays a central role in the female reproductive system, serving as the canal for menstrual flow, sexual intercourse, and childbirth. It naturally maintains a delicate balance of bacteria and a specific acidic pH to protect itself from infection.
What it is: A very common vaginal yeast infection caused by an overgrowth of the Candida fungus, which naturally resides in small amounts within the vaginal environment.
Common signs: Intense vaginal itching, burning, soreness, and a thick, white, odourless discharge that often resembles cottage cheese.
When to Worry:
Symptoms do not resolve after using over-the-counter antifungal treatments
You experience frequent, recurrent episodes (more than four times a year)
Severe local swelling, skin cracking, or visible bleeding develops
When to See a Doctor:
Promptly. To confirm the diagnosis, rule out other conditions, or obtain prescription-strength maintenance therapy if it is recurrent.
What it is: The most common cause of abnormal vaginal discharge, resulting from a shift in the natural balance of vaginal bacteria, where protective lactobacilli are outnumbered by anaerobic bacteria.
Common signs: A thin, watery, greyish-white vaginal discharge accompanied by a distinct, strong, fishy odour that often becomes more noticeable after sexual intercourse.
When to Worry:
Symptoms arise during pregnancy, as untreated BV can increase the risk of preterm birth
Discomfort becomes severe or the discharge changes to a yellowish-green colour
When to See a Doctor:
Soon. Prescription antibiotics are typically required to restore the healthy bacterial balance and resolve the odor.
What it is: A common sexually transmitted infection (STI) caused by a microscopic, single-celled parasite called Trichomonas vaginalis.
Common signs: A profuse, frothy, yellowish-green vaginal discharge, a strong foul odour, vaginal soreness, itching, and pain or burning during urination.
When to Worry:
Persistent genital irritation or painful intercourse following a new sexual partner
Severe burning during urination or significant pelvic discomfort
When to See a Doctor:
Promptly. Antibiotics are necessary to cure the infection, and current sexual partners must be treated simultaneously to prevent reinfection.
What it is: Two highly common bacterial sexually transmitted infections that infect the cervix and vaginal lining, often co-existing.
Common signs: Frequently entirely asymptomatic; when symptoms do occur, they include an altered vaginal discharge, pain when passing urine, or bleeding between periods or after sex.
When to Worry:
Unexpected bleeding between menstrual periods or after sexual intercourse
Lower abdominal or pelvic pain accompanied by unusual discharge
Notification that a sexual partner has been diagnosed with an STI
When to See a Doctor:
Promptly. Simple screening tests can identify these bacteria, and early antibiotic treatment is crucial to prevent long-term damage to fertility.
What it is: The thinning, drying, and inflammation of the vaginal walls caused by a significant drop in estrogen levels, most commonly occurring during or after menopause.
Common signs: Vaginal dryness, burning, a lack of natural lubrication, pain or minor bleeding during intercourse, and an increased frequency of urinary tract infections (UTIs).
When to Worry:
Vaginal dryness or pain that makes sexual intimacy distressing or impossible
Any postmenopausal bleeding (bleeding occurring a year or more after periods have stopped), which always requires investigation
When to See a Doctor:
Soon. Localised treatments, such as vaginal estrogen creams, rings, or pessaries, are highly effective at restoring tissue health.
What it is: Vaginal irritation or inflammation caused by an allergic reaction or sensitivity to external products rather than an infectious organism.
Common signs: Vaginal burning, itching, redness, and discomfort, often triggered by scented soaps, bubble baths, douches, feminine hygiene sprays, or latex condoms.
When to Worry:
The vaginal lining becomes intensely painful, raw, or swollen
Symptoms do not improve after eliminating suspected chemical irritants
When to See a Doctor:
Routinely. To confirm that no underlying infection is present and to discuss soothing topical treatments to restore the vaginal skin barrier.
What it is: A condition where the structural tissues and muscles supporting the pelvic organs weaken, causing the vaginal walls to stretch and bulge downward, sometimes allowing the bladder, bowel, or uterus to sag into the vaginal canal.
Common signs: A sensation of heaviness, fullness, or a dragging feeling in the pelvis; feeling or seeing a physical bulge inside or protruding from the vagina; and difficulties with bowel or bladder emptying.
When to Worry:
A bulge protrudes completely outside the vagina, causing skin irritation or bleeding
Inability to pass urine or completely empty the bladder
When to See a Doctor:
Routinely for manageable symptoms to discuss pelvic floor exercises or a vaginal pessary; urgently if you experience a complete inability to urinate.
What it is: An object that has been left inside the vaginal vault, most commonly a forgotten or misplaced tampon, contraceptive device, or condom.
Common signs: A rapidly developing, extremely foul-smelling vaginal discharge (often brown or blood-stained), localised pelvic discomfort, and vaginal irritation.
When to Worry:
The object cannot be easily reached or safely removed at home
A high fever, shivering, dizziness, vomiting, or a sudden drop in blood pressure develops (potential signs of Toxic Shock Syndrome, a rare but life-threatening complication)
When to See a Doctor:
Urgently. A doctor can quickly and painlessly locate and remove the object; go to A&E immediately if you have signs of a systemic infection or high fever.
What it is: An abnormal, tunnel-like opening or connection that develops between the vagina and another nearby pelvic organ, such as the bladder (vesicovaginal) or the rectum (rectovaginal). It usually results from childbirth trauma, surgery, or inflammatory bowel disease.
Common signs: Constant, uncontrollable leakage of urine or faeces/gas directly from the vagina, accompanied by persistent foul odour and severe local skin irritation.
When to Worry:
Any unexplained, involuntary leakage of fluid, gas, or stool from the vaginal opening
When to See a Doctor:
Soon. A specialist referral to a Consultant in Obstetrics and Gynaecology (O&G) or a Urogynzecologist is necessary, as surgical repair is typically required to close the abnormal connection.
What it is: A very rare malignancy originating in the cells lining the vagina, most frequently presenting as a secondary spread from cervical or vulval cancer, but occasionally arising as a primary tumor.
Common signs: Abnormal vaginal bleeding (particularly after intercourse or after menopause), a palpable lump or mass within the vaginal canal, persistent watery discharge, and pelvic pain.
When to Worry:
Unexplained bleeding between periods, after intercourse, or at any time post-menopause
Feeling a new, hard, or persistent lump or growth inside the vagina
When to See a Doctor:
Soon. While vaginal lumps and bleeding are often caused by benign conditions, any persistent or unexplained symptom must be formally evaluated by a physician to rule out malignancy.
Changes in the colour, consistency, or odour of vaginal discharge – are common indicators of an underlying imbalance or infection.
Any postmenopausal bleeding PMB) or unexplained bleeding between periods – is abnormal and always requires formal medical evaluation.
Douching or using heavily scented products inside the vagina is unhelpful – it disrupts its natural pH and microbiome, often causing or worsening problems.
Vaginal symptoms are standard clinical presentations – never let embarrassment or self-consciousness prevent you from seeking medical advice.
