Where do hemorrhoids form
Hemorrhoids are anatomical structures ordinarily present in all individuals. It is the abnormal dilation of the veins in the anus and rectum that causes hemorrhoidal disease.
HEMORRHOIDS, IN BRIEF
Each has blood vessels since birth called hemorrhoids. Naturally present in our body at the anal level, hemorrhoids participate in its proper functioning. However, the term “hemorrhoids” is ambiguous and often misused. Indeed, in everyday language, hemorrhoids can designate two things:
- Blood vessels in the rectum and anus.
- The hemorrhoidal disease. It appears when the hemorrhoids bleed, become painful and/or increase in volume.
- Hemorrhoids are not inherently a disease.
- Saying “I have hemorrhoids” is an abuse of language to mean “I suffer from my hemorrhoids.”
WHAT DO HEMORRHOIDS LOOK LIKE?
Hemorrhoids are veins. They form a network of interlaced blood vessels, located around and inside the anus and rectum.
They look like clusters of small veins. These clusters are not linear unlike the veins of the legs. In general, 3 to 4 clusters form hemorrhoids. We also talk about hemorrhoidal packages.
WHERE ARE THE HEMORRHOIDS LOCATED?
Positioned in the upper part of the anal canal, they are located at the exit of the rectum.
Hemorrhoids have a role in anal continence as they participate in the closure of the rectum. At the time of defecation, and with the pushing force, the arterial and venous network formed by the hemorrhoids flattens to allow passage of stool.
THE DIFFERENT FORMS OF HEMORRHOIDS
There are several forms of hemorrhoids:
- internal hemorrhoids
- external hemorrhoids
Internal hemorrhoids are located inside the anal canal, at the lower part of the rectum. They are therefore not visible and remain difficult to identify.
In the case of medical consultation, the only way for your doctor to examine them is to use an anoscope. This medical device, introduced into the anus, makes it possible to observe the internal hemorrhoids.
External hemorrhoids are located outside the anus. They are therefore easier to identify than internal hemorrhoids. It is only in case of complications that they become visible and painful.
External hemorrhoids develop in two places:
- around the anus,
- under the rectal orifice.

When the blood vessels cover the conduit of the anus, we speak of internal hemorrhoids. In the case of a hemorrhoidal crisis, it is the most dangerous form because it has 4 degrees of evolution when the care is not fast.
- The first degree corresponds to the beginning of the hemorrhoidal crisis. At this stage, the manifestations are limited to discomfort, burning or itching. All this while the hemorrhoids remain inside the anus.
- The second degree corresponds to the association of the initial symptoms with the externalization of the hemorrhoids during the defecation. However, they come back to their normal position as soon as you stop pushing. Small bleeding may occur at this time, accompanied by the feeling of pressure.
- In the third degree, hemorrhoids do not spontaneously return to their place. They must be gently put back inside with the fingers after the stool.
- The fourth degree, the most critical phase, corresponds to the stage where the hemorrhoids cannot be replaced again, even with the fingers and stay outside. This should not be confused with external hemorrhoids.
As long as they stay inside, the hemorrhoids remain entirely painless. This makes their diagnosis more difficult than external hemorrhoids.
External hemorrhoids are called when the network of vessels is located around the folds of the skin of the anus and part of the rectum. Being located outside, they swell more quickly because of the sensitivity of the nerve fibers of this region.
The protuberances appear in the anus due to dilation due to pressure on the veins, which makes their diagnosis easy. They are also easier to treat than interns.
Apart from the protuberances, the main characteristic of external hemorrhoids is a pain. They remain painful even outside the moments of defecation, especially when you stay in a sitting position for a long time. Their external nature exposes them more, adding to the pain the discomfort.
Just like internal hemorrhoids, an external hemorrhoidal crisis has several phases of evolution. An external hemorrhoid changes size, shape, and even color.
At first, it will only be a few millimeters of protuberances. As the crisis evolves, they evolve to the size of a walnut 3 centimeters in diameter. At this point, the protuberances become protrusions.
External hemorrhoids can take many forms from one individual to another. If in some people they are round or oval, in others they are flattened or creased.
Like size, the color of hemorrhoids changes according to the stage of evolution of the crisis. This is a powerful indicator that will support the diagnosis of your doctor.
Indeed, when the crisis is still in its infancy, the protuberances are dark or brown. Some will have the same color as your skin. As the crisis progresses, hemorrhoids become bright red due to blood clogging in the vessels.
At the last stage, they can even turn purple or purplish blue. We are no longer talking about illness, but about hemorrhoidal thrombosis.
Whatever the stage of evolution, it is crucial to intervene quickly to treat hemorrhoids. Among the solutions to calm the symptoms are creams. But what do we know about them?
