  5. 5.Groin Hernia Requiring a Doctor's Examination

    A hernia occurs when a loop of intestine bulges out through the abdominal wall. With age, the supportive tissues that keep organs within the abdomen become weaker, and the risk for a hernia increases. Groin hernias, called inguinal hernias, are the most common type. They often result due to muscle straining, such as during heavy lifting.A complicated groin hernia, also called an incarcerated hernia, is a medical emergency. This type of hernia cannot be easily reduced, in other words pushed back without surgery. An incarcerated hernia is at high risk of becoming strangulated, meaning that pressure on the loop of bowel can cause the trapped segment to lose blood supply. Unless the blood supply is restored promptly, the tissue can rapidly die. This is a life-threatening condition.

    Complicated (incarcerated) groin hernias are a life-threatening condition. However, if treatment is performed early, the prognosis after surgery is excellent.Chronic pain 1 year out from the surgery is reported by some patients, but it is likely to dissipate over time.

    Rarity:
    Rare
    Top Symptoms:
    nausea, nausea or vomiting, fever, groin pain, groin lump
    Urgency:
    Emergency medical service
