In short
Hemorrhoids are swollen veins in and around the anus that cause itching, discomfort, and bleeding — but any rectal bleeding is worth having checked rather than assumed.
Emergency if: Bleeding from the bottom that will not stop, a lot of blood or large clots, feeling faint or dizzy with bleeding, or severe pain: call emergency services now or go to an emergency department now. Do not drive yourself.

What Hemorrhoids Are
Hemorrhoids are swollen, enlarged veins in and around the anus and lower rectum — a very common condition, especially with straining during bowel movements, pregnancy, chronic constipation or diarrhea, and prolonged sitting. Everyone has this network of veins; hemorrhoids are simply when they become swollen and symptomatic.
Internal hemorrhoids form inside the rectum and are often painless, while external hemorrhoids form under the skin around the anus and can be itchy, painful, or swollen, especially if a clot forms inside one — a particularly painful variant called a thrombosed hemorrhoid.
02
Common Symptoms
Bright red blood on toilet paper or in the toilet bowl, itching, discomfort, and a feeling of a lump near the anus are the typical symptoms. Internal hemorrhoids can also cause a sensation of not fully emptying the bowel.
Bright red bleeding limited to wiping, with no other symptoms, is often hemorrhoids. But bleeding that will not stop, a lot of blood or large clots, or severe pain is an emergency: call emergency services now or go to an emergency department now. Dark or maroon blood, blood mixed into the stool, or bleeding with weight loss, a change in bowel habits or abdominal pain needs a doctor's assessment rather than being assumed to be hemorrhoids.
03
Why an Exam Still Matters
Hemorrhoids are diagnosed by a visual and physical exam, and a doctor can usually tell within minutes. Because rectal bleeding can also come from other causes, including polyps or, less commonly, colorectal cancer, a first episode of rectal bleeding — especially over the age of 45, or with a family history of colon cancer — is generally worth a clinical evaluation rather than self-treatment alone.
Anemia from long-standing, unnoticed blood loss can develop gradually, which is one more reason not to keep self-treating recurring bleeding indefinitely without ever having it looked at.
04
Treatment
Most hemorrhoids improve with simple measures: more fiber and fluids to soften stool, avoiding straining, warm sitz baths, and over-the-counter creams or suppositories for symptom relief. These measures typically bring relief within a week or so.
Hemorrhoids that don't improve, or that are large and prolapsing, can be treated with in-office procedures such as rubber band ligation, and surgery is reserved for more severe or persistent cases. A thrombosed external hemorrhoid causing severe pain can sometimes be treated more quickly with a small procedure if seen within the first couple of days.
05
Prevention
A high-fiber diet, adequate fluids, regular exercise, and not lingering on the toilet or straining are the main preventive habits, and they also help keep hemorrhoids from coming back after treatment.
A primary care doctor or gastroenterologist can evaluate persistent or recurring symptoms, and can also arrange a colonoscopy when bleeding needs a closer look beyond what a physical exam can tell.
How urgent is it?
Emergency — act now
Bleeding from the bottom that will not stop, a lot of blood or large clots, feeling faint or dizzy with bleeding, or severe pain: call emergency services now or go to an emergency department now. Do not drive yourself.
Same-day — call promptly
Painless bleeding from the bottom that is new for you, a very high temperature or shivering, or pus leaking from the piles: see a doctor today.
Routine — see a doctor
Piles that are getting worse or not improving after a week of home treatment, piles that keep coming back, or any change around the anus that is not normal for you: book a doctor's visit.
