What are hemorrhoids?
Hemorrhoids are swollen blood vessels in the lower rectum and anus, similar to varicose veins. They are extremely common, affecting most people at some point in their lives. They can be internal, forming inside the rectum where they often cannot be seen or felt, or external, developing under the skin around the anus, where they may be felt as lumps.
Although hemorrhoids can cause worrying symptoms like bleeding, they are usually not serious and often settle on their own or with simple treatment. Understanding what causes them helps both in easing symptoms and in preventing them from returning. That said, because rectal bleeding can occasionally signal other conditions, it should always be checked by a doctor rather than assumed to be piles.
Symptoms
Hemorrhoid symptoms vary depending on their type and severity, and some people have no symptoms at all. Common symptoms include:
- •Bright red blood after passing a stool
- •Itching around the anus
- •A lump in or around the anus
- •Discomfort, soreness or aching, especially when sitting
- •A feeling of still needing to pass stools after going to the toilet
- •Mucus discharge
Causes and risk factors
Hemorrhoids develop when there is increased pressure on the blood vessels around the anus, causing them to swell. Many everyday factors can contribute, and often several combine. Common causes and risk factors include:
- •Straining when passing stools, often due to constipation
- •Chronic constipation or diarrhoea
- •Pregnancy, from increased pressure and hormonal changes
- •Sitting for long periods, especially on the toilet
- •Being overweight
- •A low-fibre diet
- •Age, as the supporting tissues weaken over time
Treatment and relief
Most hemorrhoids improve with simple self-help measures aimed at softening stools and reducing pressure. Eating more fibre, drinking plenty of fluids, and avoiding straining all help. Over-the-counter creams, ointments and soothing wipes from a pharmacy can ease itching and discomfort, and warm baths may provide relief. Avoiding prolonged sitting and not delaying when you need to go to the toilet also help.
If symptoms persist or are severe, a doctor can offer further treatments. These include procedures done in a clinic, such as banding (placing a small band around an internal hemorrhoid to cut off its blood supply) or injections, and, for larger or persistent hemorrhoids, surgical options. A doctor can advise which approach suits your situation, but many people find their symptoms resolve with self-help alone.
Preventing hemorrhoids
Because hemorrhoids are strongly linked to straining and constipation, preventing them largely comes down to keeping stools soft and avoiding pressure. A high-fibre diet, with plenty of vegetables, fruit, wholegrains and pulses, helps keep stools soft and regular. Drinking enough fluids supports this, and staying physically active helps keep the bowels moving.
Other helpful habits include going to the toilet when you feel the urge rather than delaying, not straining or sitting on the toilet longer than needed, and maintaining a healthy weight. For people prone to recurrent hemorrhoids, these measures can make a real difference in preventing them from coming back. If constipation is a persistent problem, addressing its cause with a doctor's help also reduces the risk.
When bleeding is not just piles
One of the most important things to understand about hemorrhoids is that, although they are a very common cause of rectal bleeding, bleeding from the bottom should never simply be assumed to be piles without being checked. Several other conditions can cause similar bleeding, some of which need prompt attention, so a proper assessment matters.
This is especially important if the bleeding is a new symptom, if it is accompanied by a change in your normal bowel habits, if the stools themselves are darker or have a different consistency, or if you have unexplained weight loss or tummy pain. These features can point to causes other than hemorrhoids and should always be discussed with a doctor.
The reassuring reality is that most rectal bleeding does turn out to be due to something minor like piles. But because the consequences of missing a more serious cause can be significant, doctors would always rather check and reassure you than have bleeding go unexamined. Seeing a doctor about rectal bleeding is sensible, not an overreaction.
Thrombosed and prolapsed hemorrhoids
Most hemorrhoids cause mild symptoms, but sometimes they become more troublesome. A thrombosed hemorrhoid occurs when a blood clot forms within an external hemorrhoid, causing a sudden, painful, firm lump near the anus. While alarming and uncomfortable, these often settle over a week or two, and a doctor can advise on relief or, occasionally, a minor procedure if the pain is severe and the clot is recent.
Internal hemorrhoids can sometimes prolapse, meaning they bulge outside the anus, particularly when passing stools. Some slip back on their own or can be gently pushed back, while larger ones may remain outside and need treatment. A doctor can grade the severity and recommend the most suitable approach, from self-help to clinic procedures.
If you develop a sudden very painful lump, a prolapse that will not go back, or symptoms that are severe or not settling, it is worth seeing a doctor. While these situations are usually not dangerous, they are uncomfortable and often treatable, so there is no need to simply endure them.
