The worst form of constipation can become haemorrhoids, which are engorged blood vessels around the anus and are commonly known as piles.
It usually happens during pregnancy due to pressure from the uterus, which restricts blood flow to the rectum.
Your doctor can recommend a cream or suppository that can be safely used in pregnancy.
High fibre diets and plenty of fluids should be used when suffering from constipation, ultimately it helps avoiding piles.
Unfortunately if you suffer from piles during pregnancy ice packs covered with a soft cloth on the area can also provide relief.
