Prostatitis: Symptoms, Causes, and Treatment in the UK

Prostatitis is a common condition characterised by inflammation or infection of the prostate gland. The prostate is a small, walnut-sized gland located just below the bladder in men, responsible for producing some of the fluid in semen. While conditions like Benign Prostatic Hyperplasia (BPH) usually affect older men, prostatitis can affect men of any age, and is the most common urological issue for men under 50 in the UK.

Unlike an enlarged prostate, which is a structural growth, prostatitis is often an inflammatory response. It can occur suddenly (acute) or persist for several months (chronic). According to NHS data, many cases are not caused by a bacterial infection but rather by nerve damage, physical injury, or irritation in the pelvic floor area.

Medical professionals categorise prostatitis into four distinct types to determine the most effective treatment plan:

• Acute Bacterial Prostatitis: This is a sudden bacterial infection. It is the least common type but has the most severe symptoms, often requiring immediate medical attention.
• Chronic Bacterial Prostatitis: This involves recurring bacterial infections. Symptoms are usually less severe than the acute form but can last for years if not treated correctly.
• Chronic Prostatitis / Chronic Pelvic Pain Syndrome (CPPS): This is the most common form, accounting for about 90% of cases. The exact cause is often unknown, but it involves persistent pelvic pain for at least three of the previous six months.
• Asymptomatic Inflammatory Prostatitis: In this type, the patient has no symptoms, and the inflammation is often discovered during tests for other conditions, such as infertility or prostate cancer screening.

The symptoms of prostatitis can vary significantly depending on whether the condition is infectious or inflammatory. Common signs include:

• Pain or a burning sensation during urination (dysuria).
• Difficulty starting urination or a weak urine flow.
• Frequent need to urinate, especially at night (nocturia).
• A persistent ache in the perineum (the area between the scrotum and anus).
• Pain in the pelvis, genitals, lower back, or buttocks.
• Painful ejaculation or erectile dysfunction.
• Cloudy or bloody urine.

In cases of acute bacterial prostatitis, you may also experience systemic symptoms similar to the flu, such as a high temperature (fever), chills, nausea, and body aches. This requires urgent assessment to prevent the infection from spreading to the bloodstream.

The cause of prostatitis depends heavily on the type diagnosed. Bacterial versions are usually caused by common strains of bacteria (such as E. coli) leaking into the prostate from the urinary tract. This can sometimes occur following a urinary tract infection (UTI) or an STI.

For Chronic Pelvic Pain Syndrome (CPPS), the cause is less clear. Contributing factors may include:

• Nerve damage in the lower urinary tract following surgery or trauma.
• Stress and anxiety, which can cause chronic tension in the pelvic floor muscles.
• Earlier bouts of bacterial prostatitis that left the area sensitive.
• Physical strain from heavy lifting with a full bladder.

Risk factors include being between 30 and 50 years of age, having a previous diagnosis of prostatitis, or having recently used a urinary catheter.

Diagnosis typically starts with a physical examination, including a digital rectal examination (DRE) where a GP gently feels the prostate gland to check for swelling or tenderness. You will usually be asked to provide a urine sample to rule out a UTI or bacterial infection.

Treatment is tailored to the type of prostatitis diagnosed:

• Antibiotics: Prescribed for bacterial prostatitis. Acute cases may require a 2–4 week course, while chronic bacterial cases may require up to 12 weeks.
• Alpha-blockers: These medications help relax the muscles where the prostate joins the bladder, making urination easier and less painful.
• Pain Relief: Over-the-counter anti-inflammatories, such as ibuprofen, can help manage pelvic discomfort.
• Lifestyle Adjustments: For non-bacterial cases, avoiding spicy foods, caffeine, and alcohol can reduce bladder irritation. Using a cushion when sitting for long periods and practicing pelvic floor relaxation exercises may also help.

If you are experiencing persistent pelvic pain or changes to your urinary habits, it is important to seek medical advice. An online GP consultation is a convenient first step to discuss your symptoms in a private, comfortable environment. Our clinicians can help differentiate between prostatitis, cystitis, and other urological conditions.

You should book an appointment if:

• Your urinary symptoms are not improving after a few days.
• You have persistent pain in your genitals or lower back.
• You are concerned about recurrent infections.
• You need advice on managing the long-term symptoms of CPPS.

Early intervention can prevent the progression of acute infections and help manage the quality-of-life impact associated with chronic pelvic pain.
