A person’s anal canal is lined with blood vessels. When these blood vessels become dilated or swollen, they can form a haemorrhoid.
The haemorrhoid itself gets infected by bacteria, this occurs when:
When healthy blood flow to the area is restricted (blood flow is required because it allows white blood cells and other immune cell proteins to flow through the anal area).
Internal haemorrhoid is one that forms in the rectum (this is the portion of the large intestine that ends at the anus).
An internal haemorrhoid may push down from the rectum, which is known as a prolapsed internal haemorrhoid, this can often be gently pushed back up into the wall of the rectum, but in doing so can be most likely to get infected.
This is because this may cut off the veins blood flow which is known as a strangulated internal haemorrhoid and this without no white cell, immune cells proteins and other immune factors supplying blood to the haemorrhoid to stop the bacteria, an infection can form quickly.
Medical diseases can also increase the chance of infected haemorrhoids.
Thrombosed haemorrhoids
Thrombosed haemorrhoids occur when either an internal or external haemorrhoid fills with blood clots.
Thrombosed haemorrhoids can become tender and painful.
These type of haemorrhoids can also become infected, which may lead to an abscess and fever.
