Sexually transmitted infections (STIs) remain common across the UK, and many people only seek help after searching for “burning when passing urine”, “unusual discharge”, “genital rash”, or “private STI testing near me”.
At Niva Medical Clinic in Stanmore, we provide same-day GP appointments for STI consultations and testing, supporting patients across Harrow, Edgware, Wembley, Bushey, Watford, Hatch End, and Northwood with fast, discreet access to care — particularly helpful for busy professionals who often delay their own health checks.
UK clinical guidance from the British Association for Sexual Health and HIV (BASHH) and National Institute for Health and Care Excellence (NICE) recommends prompt testing when symptoms occur or after potential exposure, as early treatment significantly reduces complications and onward transmission.
Common STIs: Symptoms, Risks & Complications
1. Chlamydia
About: The most commonly diagnosed bacterial STI in the UK, particularly in individuals under 25.
Common Symptoms:
- Pain when passing urine
- Abnormal vaginal or penile discharge
- Lower abdominal or pelvic pain
- Bleeding after sex
- Testicular discomfort
- Often no symptoms at all
Complications if Untreated:
- Pelvic Inflammatory Disease (PID)
- Infertility
- Ectopic pregnancy
- Chronic pelvic pain
- Epididymo-orchitis in men
Chlamydia is typically detected using a NAAT (PCR) urine test or swab and is curable with antibiotics when diagnosed early.
2. Gonorrhoea
About: A bacterial infection affecting the genitals, rectum, or throat.
Common Symptoms:
- Thick yellow or green discharge
- Painful urination
- Rectal discomfort or discharge
- Sore throat following oral sex
- Intermenstrual bleeding in women
Complications:
- PID
- Infertility
- Disseminated gonococcal infection (joint pain, skin rash)
- Increased HIV transmission risk
Testing involves urine or site-specific swabs. Rising antimicrobial resistance makes early diagnosis essential, as emphasised by BASHH guidance.
3. Syphilis
About: A bacterial STI with multiple stages, sometimes called “the great imitator” due to varied symptoms.
Primary Stage:
- Painless genital ulcer (chancre)
Secondary Stage:
- Rash (often on palms/soles)
- Swollen glands
- Fever or fatigue
Late Complications if Untreated:
- Neurological damage
- Vision loss
- Cardiovascular complications
- Cognitive decline
Diagnosis is via blood test, and early antibiotic treatment is highly effective.
4. HIV (Human Immunodeficiency Virus)
About: A viral infection affecting the immune system.
Early Symptoms (Seroconversion):
- Fever
- Sore throat
- Rash
- Fatigue
- Swollen lymph nodes
Many individuals remain asymptomatic for years.
Complications Without Treatment:
- Progressive immune suppression
- Opportunistic infections
- Acquired Immunodeficiency Syndrome (AIDS)
A 4th-generation blood test
is typically reliable from 45 days post-exposure. Early treatment with antiretroviral therapy allows individuals to live normal life spans and reduces transmission risk to effectively zero when viral load is undetectable (U=U).
5. Genital herpes (HSV)
About: Caused by Herpes Simplex Virus types 1 or 2.
Symptoms
- Painful genital blisters or ulcers
- Tingling or burning before outbreaks
- Flu-like illness during first episode
Complications:
- Recurrent outbreaks
- Neonatal herpes risk during pregnancy
Testing involves swabbing active lesions.
6. Human papillomavirus (HPV)
About: A common viral infection linked to genital warts and certain cancers.
Symptoms:
- Often none
- Genital warts (low-risk types)
Complications:
- Cervical cancer
- Anal cancer
- Oropharyngeal cancer
High-risk HPV strains are detected via cervical screening, in line with NHS national screening programmes.
7. Hepatitis B & Hepatitis C
About: Blood-borne viruses affecting the liver.
Symptoms:
- Fatigue
- Jaundice
- Nausea
- Abdominal discomfort
Long-Term Risks:
- Chronic liver disease
- Cirrhosis
- Liver cancer
Diagnosis is via blood test. Vaccination is available for Hepatitis B.
