Similarly, straining, such as to deliver a baby or to effect a bowel movement, increases pressure on the abdominal cavity, which impedes the return of blood from the veins of the anus and the large intestine.
Demikian pula, mengejan, seperti sewaktu melahirkan atau sewaktu buang air besar, meningkatkan tekanan pada rongga perut, yang menghambat kembalinya darah dari vena di anus dan usus besar.
