Internal hemorrhage refers to bleeding that occurs inside the body, often due to injury, surgery, or medical conditions. This type of bleeding can happen in various organs, such as the lungs, stomach, or brain, and may lead to serious health complications if not treated promptly. Symptoms can include pain, swelling, or signs of shock, such as weakness and confusion. Diagnosis of internal hemorrhage typically involves imaging tests like CT scans or ultrasounds to locate the source of the bleeding. Treatment may require interventions such as surgery or blood transfusions, depending on the severity and location of the hemorrhage. Early detection is crucial for effective management.
