- Online GPs can provide clinical advice, testing referrals, and initial prescriptions.
What is Proctitis?
Proctitis is a condition characterized by inflammation of the mucous membrane lining the rectum, which is the final section of the large intestine. In the UK, it is a relatively common digestive concern that can affect individuals of any age or gender. While it can cause significant discomfort and anxiety, it is usually manageable once the underlying cause is identified.
Unlike general bowel conditions, proctitis specifically targets the bottom 10 to 15 centimetres of the gut. Following NHS clinical pathways, diagnosis involves distinguishing between infectious causes, such as bacterial or viral infections, and non-infectious causes, such as chronic inflammatory conditions like ulcerative colitis or Crohn's disease.
Recognising the Symptoms of Proctitis
The symptoms of proctitis can range from mild irritation to severe, debilitating pain. One of the most hallmark symptoms of this condition is tenesmus. This is the frequent or continuous feeling that you need to have a bowel movement, even if your rectum is empty.
Other common symptoms reported by UK patients include:
- Rectal bleeding or the presence of bright red blood on toilet paper.
- A feeling of fullness or pressure in the rectal area.
- Pain during bowel movements or a dull ache in the pelvic region.
- Rectal discharge that may appear as mucus or pus.
- Diarrhoea or, conversely, difficulty passing stools despite the urge.
What Causes Rectal Inflammation?
According to NICE (National Institute for Health and Care Excellence) guidelines, proctitis is rarely a standalone diagnosis; it is typically a symptom of another health issue. Identifying the root cause is essential for effective treatment.
1. Sexually Transmitted Infections (STIs)
Infectious proctitis is frequently linked to STIs, particularly among men who have sex with men (MSM) or through unprotected anal intercourse. Common pathogens include chlamydia, gonorrhoea, syphilis, and herpes simplex virus (HSV). This is often referred to as 'proctitis-proctocolitis'.
2. Inflammatory Bowel Disease (IBD)
Approximately 30% of people with ulcerative colitis have inflammation limited to the rectum (ulcerative proctitis). Crohn's disease can also affect the rectal lining. These are chronic conditions requiring long-term specialist management.
3. Radiation Proctitis
Patients undergoing radiation therapy for cancers in the pelvic region (such as prostate, cervical, or rectal cancer) may develop inflammation as a side effect. This can occur shortly after treatment or years later.
4. Other Causes
Less common causes include 'diversion proctitis', which occurs after certain types of bowel surgery, or chemical irritation from soaps and enemas.
When to Speak to an Online Doctor in the UK
Rectal symptoms can be embarrassing to discuss, leading many to delay seeking help. However, an online GP consultation offers a discreet and convenient way to start your journey toward recovery. If you are experiencing persistent rectal pain, discharge, or a change in bowel habits, speaking to a GP online allows you to discuss your symptoms from the comfort of your home.
A UK online doctor can assess your clinical history to determine if your symptoms are likely related to an infection or a chronic digestive issue. They can provide advice on how to obtain STI testing locally or via home-sampling kits and can issue private prescriptions for topical treatments like suppositories or foams if appropriate. If your symptoms suggest IBD, the online doctor can provide a sick note for work and a referral letter for a physical examination or a specialist gastroenterologist.
Management and Treatment Options
The treatment for proctitis depends entirely on the cause. Once diagnosed, most patients see a rapid improvement in symptoms.
- Infection: Antibiotics (for chlamydia or gonorrhoea) or antiviral medications (for herpes) are the gold standard. It is vital to notify any sexual partners to prevent re-infection.
- IBD: Doctors may prescribe 5-ASA (aminosalicylate) medications, often in the form of suppositories, enemas, or tablets to reduce inflammation.
- Radiation: Management may include stool softeners to prevent irritation or specialized procedures like argon plasma coagulation to seal bleeding vessels.
Self-care measures include avoiding spicy foods, caffeine, and high-fibre foods during flare-ups to reduce bowel irritation.
Red flags — when to seek urgent help
