Which condition can lead to complications if not treated promptly?

Ectopic pregnancy is a condition in which a fertilized egg implants outside the uterus, most commonly in a fallopian tube. If not treated promptly, this condition can lead to severe complications, including internal bleeding, which may be life-threatening. The placement of the fertilized egg in an abnormal location can cause growth and rupture of the tissue, leading to significant health risks for the individual.

While the other conditions mentioned also have potential complications, ectopic pregnancy is particularly urgent because the danger of rupture can occur quickly, often within the first few weeks of pregnancy. Immediate medical intervention, such as medication or surgery, is often required to prevent serious outcomes. The other conditions do pose risks, but they typically do not have the same level of immediate life-threatening urgency as an ectopic pregnancy.
