Causes
Haemorrhoids are caused when straining occurs on the blood vessels in and around the anus. Constipation is typically the cause as it leads to straining which increases pressure on veins inside the anal canal. Pregnant women and new mums are also susceptible to haemorrhoids for a number of reasons. The growing baby in the womb places extra pressure in the abdomen, furthermore, hormonal changes making blood flow sluggish puts increased pressure on veins. Straining during labour is also a further cause of haemorrhoids.
