An ectopic pregnancy occurs when a fertilized egg implants outside the uterus, most commonly in a fallopian tube. This condition can lead to serious health risks for the person, as the growing tissue can cause the tube to rupture, leading to internal bleeding. Symptoms of an ectopic pregnancy may include abdominal pain, irregular bleeding, and dizziness. Early diagnosis through ultrasound and blood tests is crucial for treatment, which may involve medication or surgery to prevent complications and protect the person's health.
