Haemorrhoids can affect any person, any time. they are of common occurrence. There are different causes of haemorrhoid.Read on to know about the causes.
What causes haemorrhoids
Haemorrhoids, which are normal structures
present at the upper part of the anal canal, are supported by two tissues.
Constant pressure on this tissue (for example, straining when constipated
or due to age) tends to degenerate the tissue. As a result the haemorrhoids
tend to distend. Because of lack of support the haemorrhoids become
swollen (like a balloon filled with water) and are now sensitive to injury.
Constant rubbing by the hard faecal matter leads to bursting of the capillaries
and thus leads to bleeding. As the condition progresses, the connective
tissue ruptures and the haemorrhoids become permanently protruded.
What kind of person
is most at risk
Haemorrhoids is one condition that
can affect any person at any time. Poor eating habits, irregular
bowel movement, frequent changes in lifestyle, excessive travel, prolonged
standing or sitting, etc. can all contribute to contracting haemorrhoids.
Constipation: Straining
during constipation puts pressure on the veins, which either bleed or protrude
outside the rectum.
Pregnancy: Pregnancy is
a common cause for haemorrhoids in women. There is increased pressure
in the veins due to the enlarging womb and increased blood volume.
Standing or sitting for a long period:
People who tend to stand (for e.g., teachers, factory workers) or sit (for
example, office workers) for long periods tend to accumulate blood in the
veins, which can lead to haemorrhoids.
Overweight: Being overweight
puts extra pressure on the haemorrhoidal veins.
