An abdominal hematoma lump is a localized collection of blood beneath the skin or within abdominal tissues, often caused by injury, surgery, or blood-thinning medications. Doctors diagnose it through a physical exam and imaging tests such as an ultrasound or CT scan to confirm size and location. Treatment depends on severity: mild cases typically resolve with rest, cold compresses, and pain relief, while larger or complicated hematomas may require drainage or surgery.
If you've noticed a lump, swelling, or unexplained abdominal pain, understanding the cause early can help you avoid complications and get the right care faster. Take a free, instant, online symptom check to better understand your symptoms and confidently navigate your next steps.

Submit your own QuestionAn abdominal hematoma is a collection of blood that builds up in the tissues of your belly, often from an injury or trauma. A doctor will first examine your abdomen, asking about pain or recent injuries. To get a clear picture, they usually use imaging tests such as an ultrasound or a CT scan. These tests help determine the size and exact location of the hematoma. For treatment, if the hematoma is small and the symptoms are mild, doctors generally choose conservative management. This means you may need to rest, apply ice to the area, and take pain relievers. This helps the body reabsorb the blood over time, and you are usually monitored with follow-up exams. However, if the hematoma is large, causing severe pain, or showing signs of complications like ongoing bleeding, surgery might be necessary to remove the blood clot and stop the bleeding. The treatment plan is chosen based on the severity of the hematoma, its impact on your health, and how it affects nearby tissues.
