Hemorrhoids are normal vascular cushions that sit inside the anal canal and help with continence. The problem we call "hemorrhoids" begins when these cushions become enlarged, congested or displaced, producing bleeding, swelling, itching or pain. Understanding that distinction matters: the goal of treatment is not to remove healthy tissue, but to settle tissue that has become symptomatic.

What causes hemorrhoids?

The mechanism is increased pressure on the anal vascular cushions over time. Straining during bowel movements is the most common driver, usually linked to a low-fibre diet and inadequate fluid intake. Prolonged sitting, chronic constipation or diarrhoea, heavy lifting, and the weight and hormonal changes of pregnancy all contribute. A family tendency toward weaker connective tissue plays a part in some patients as well.

Internal versus external hemorrhoids

Where the problem sits changes both the symptoms and the treatment. Internal hemorrhoids form above the dentate line, are usually painless, and announce themselves with bright red bleeding or a sense of prolapse. External hemorrhoids sit below that line, where the skin is rich in pain fibres, so they tend to cause discomfort, swelling and a palpable lump. Many patients have a mixed picture.

How hemorrhoids are graded

Internal hemorrhoids are classified from Grade 1 to Grade 4 according to how far they prolapse. The grade guides the choice between conservative care, an office procedure and surgery. The detail of each stage, and what it means for you, is covered in the dedicated page on hemorrhoid grades.

Symptoms and warning signs

Typical complaints include painless bleeding seen on the paper or in the bowl, itching, a feeling of fullness, mucus discharge, or a lump at the anal margin. A fuller breakdown is on the hemorrhoid symptoms page, and bleeding in particular is discussed in bleeding hemorrhoids. One point cannot be overstated: rectal bleeding should never be assumed to be hemorrhoids until a doctor has confirmed it, because other conditions can look identical.

Treatment options at a glance

Most early hemorrhoids settle with simple measures, which is why conservative management is always the starting point. When symptoms persist or the disease is more advanced, modern options range from office-based procedures to laser hemorrhoid treatment and, in selected cases, surgical methods. Our full hemorrhoid treatment page explains how we choose between them.

When to see a doctor

Book an assessment if bleeding is new, persistent or heavy, if you notice a change in bowel habit, if there is pain that is worsening, or if a lump does not settle. A proctologist can confirm the diagnosis quickly and, just as importantly, rule out anything more serious. Two conditions share symptoms with hemorrhoids and are worth understanding: an anal fissure can also cause bleeding, and a perianal skin tag is often mistaken for an external pile.

How hemorrhoids are diagnosed

Diagnosis begins with the story, painless bleeding, a sense of prolapse, itching or a lump, and is confirmed by examination. This matters more than it might seem, because the symptoms of hemorrhoids overlap with several other conditions, and only an examination distinguishes them reliably. A doctor confirms the type and grade, checks for other causes of bleeding, and rules out anything more serious. The firm principle is that rectal bleeding should never be assumed to be hemorrhoids until it has been assessed, a point made in detail on the bleeding hemorrhoids page.

Who gets hemorrhoids, and why so common

Hemorrhoids are among the most common conditions affecting adults, and the reasons are built into modern life. Low-fibre diets, inadequate fluids, prolonged sitting and the habit of straining all raise pressure on the anal cushions over time. Pregnancy adds its own combination of pressure and hormonal change, which is why hemorrhoids are so frequent in expectant mothers, the subject of the hemorrhoids during pregnancy page. Understanding that the condition is common and mechanical, rather than rare or alarming, helps put it in perspective.

The two faces of hemorrhoids: bleeding and discomfort

Most hemorrhoid problems present in one of two ways, and which one usually points to the type. Painless bleeding tends to come from internal hemorrhoids, which sit above the dentate line where there are few pain nerves. Discomfort, swelling and a tender lump point more to external hemorrhoids in the pain-sensitive skin below that line. When an external hemorrhoid suddenly becomes very painful and hard, a clot may have formed, the situation covered on the thrombosed hemorrhoid page. Recognising which pattern fits helps set expectations before you are even seen.

The treatment ladder, from simple to definitive

Hemorrhoid treatment follows a sensible ladder. The first rung is always conservative: more fibre, more water, less straining and sitz baths, which settle most early hemorrhoids and which are detailed on the conservative care page. When symptoms persist or the disease is more advanced, the next rungs are office-based and minimally invasive procedures, with laser treatment offering a particularly gentle recovery. Surgery sits at the top of the ladder for the most advanced disease, and the techniques are compared on the hemorrhoid surgery page. The guiding idea is to climb only as high as the problem requires.

Preventing hemorrhoids from returning

No treatment lasts if the cause continues, which is why prevention is part of every plan rather than an afterthought. Keeping stools soft through adequate fibre and fluids, avoiding prolonged straining, not lingering on the toilet, and staying active all reduce the pressure that creates hemorrhoids in the first place. Patients who adopt these habits after treatment have markedly lower recurrence, and the same measures double as first-line care if symptoms ever return.
