Constipation
Constipation and long straining are the most often named triggers of hemorrhoids: in the sliding-lining theory, pushing down again and again gradually loosens the tissue that holds the anal cushions, and they swell and slide down. Conversely, fiber that softens stools cut the risk of hemorrhoid bleeding by 50% across 7 randomized trials.

A normal structure that slipped

THE SHORT ANSWER

Everyone has anal cushions that help seal the anus; when their supports loosen, they swell and slide down, and become hemorrhoids. The typical sign is painless bright red bleeding with a bowel movement.

WHAT IT MEANS FOR YOU

Bleeding that won't stop, a lot of blood or large clots, or severe pain: go to the emergency department now, and don't drive yourself.

READ THE ORIGINAL

Everyone has a few blood-rich pads inside the anal canal, called anal cushions, three of them main ones. They are not a disease but part of the sealing system: the ring of sphincter muscle cannot close completely on its own, and the cushions fill the gap so that the anus stays tightly sealed at rest.

When the connective tissue holding the cushions in place loosens and breaks down, they swell with blood, enlarge and slide downward, and start to bleed or come out. Only then are they called hemorrhoids (piles). So hemorrhoids are not something extra that has grown; they are a structure you already had, out of place.

Their most typical sign is painless bright red bleeding with a bowel movement, dripping into the toilet or on the paper. But you can't decide on your own that bleeding is from hemorrhoids, especially over 50, or if the blood is dark, your bowel habits change, or you lose weight or become anemic: have a doctor check your bowel.

If the bleeding won't stop, there is a lot of blood or large clots, or the pain is severe, go to the emergency department now, and don't drive yourself.
