External bleeding is easy to spot: you know when you get a cut or an injury that bleeds on the outside of your body. Internal bleeding, on the other hand, is a little more difficult to diagnose, and it can be tough to tell when you’re bleeding on the inside. Fortunately, there are a list of symptoms that you can watch out for to tell whether or not you are bleeding internally. In this article, we’ll go over all of the symptoms of internal bleeding, as well as how a doctor might diagnose you and what causes internal bleeding. And remember: if you believe you are having a medical emergency, call emergency services right away.

Things You Should Know

  • Symptoms of internal bleeding include cramping, swelling, bruising, blood in vomit, urine, or stool, and dizziness.
  • The most common cause of internal bleeding is trauma or injury. You may also have internal bleeding due to blood disorders or GI issues.
  • To diagnose your internal bleeding, your doctor will start with a physical exam. They may also order a CT scan or an angiography.
  • Treatment of internal bleeding depends on how severe it is. For mild cases, you may just need rest. For severe cases, you may need surgery.

    Internal bleeding in the stomach or GI tract will often cause cramping and pain in your torso. If your cramps are severe and only get worse, seek medical attention right away. [1]

    If you are hit in the stomach or experience some other blunt force trauma, internal bleeding may change the way your abdomen feels. Lightly press on your stomach around the area you were injured. If it feels swollen, painful, tight, full, or more tense than usual, you may be bleeding internally. [2]
    • In some instances, you may even be able to see blood moving towards the skin on your abdomen. If you notice this, call an ambulance immediately.
    • Blood in the abdomen can be a sign that you have ruptured one of your internal organs, which can be incredibly dangerous if not treated promptly.

    Most cases of internal bleeding come after trauma or injury that can lead to hemorrhaging. Locate the area where you injured yourself and look for any immediate or dark bruising in the area. This, alongside intense pain, can be a sign of very serious internal bleeding. [4]
    • If the pain is more severe than what you may expect from the visible injuries, there’s a chance that there is a more serious injury that you cannot see. It’s always safer to assume something more is wrong than it is to assume you are overreacting to an injury.
    • Significant pain in an area may also be a sign of a broken bone or another ailment. You should always seek help if you're in a lot of pain, but it's not necessarily due to internal bleeding.
    • If you’re taking a blood thinner, you may have an increased risk of bruising and internal bleeding.

    Blood loss can make you feel more tired than usual. You might feel overly exhausted or unable to stay awake, which could be signs that your body is losing blood rapidly. [5]

    The blood loss caused by internal bleeding can lead to weakness, sweating, and pale skin. While you should be able to determine if you are sweating profusely with ease, check or get someone else to check your skin for paleness or clamminess as further signs of possible internal bleeding. [6]
    • These symptoms may become more severe and more obvious if you try to stand up or move around too much.

    While injury might cause some short-term breathlessness, the blood loss associated with internal bleeding may make breathing difficult after the shock of the injury has disappeared. Focus on breathing regularly and staying calm to avoid hyperventilation. If you notice you are having trouble breathing, seek medical assistance. [7]
    • If you cannot breathe easily, find someone who is able to keep you calm, help you breathe and watch over you while you wait for help to arrive. Breathing difficulties can be incredibly dangerous if not resolved quickly.
    • Depending on how you've injured yourself, you may have just had the wind knocked out of you. Stay calm and your breathing may return to normal soon after.

    Watch for tingling or paralysis in your face, arms, or legs since these could all be signs of bleeding around your brain. If you notice these symptoms, immediately call 911 so you don’t suffer any brain damage. [8]
    • Other symptoms of cerebral bleeding may include trouble speaking, loss of coordination, and a sudden severe headache.

    When you lose a lot of blood very rapidly, you may feel lightheaded, dizzy, or confused about where you are. Take note of these symptoms and contact emergency services if they persist. [9]
    • Going into shock after an injury can also sometimes cause confusion. While it doesn’t necessarily mean you have internal bleeding, confusion is a sign of a serious injury.

    Depending on the cause of your internal bleeding, the blood loss itself or even the pain of injury may cause nausea or vomiting. If your vomit is bright red, you might be throwing up blood. If you already suspect internal bleeding due to other symptoms, you need to call emergency services right away. [10]
    • On the other hand, if you suspect internal bleeding and your vomit looks like coffee grounds, call an ambulance. Vomit that looks like coffee grounds can indicate internal bleeding in your GI tract.

    The blood from an internal injury anywhere in your digestive system will often be visible in your urine. If you see any blood in the toilet after urinating, seek medical help immediately. Though there are many causes of bloody urine (or red urine), including UTIs and certain medications, it's best to be safe (especially if you suspect internal bleeding due to other symptoms). [11]

    If you have internal bleeding in your digestive tract, the blood may exit via your feces. If you go to the bathroom and your stool looks black or sticky like tar, you may have internal bleeding. [12]

    Bleeding disorders make it hard for your body to create blood clots and stop bleeding. These disorders can turn minor injuries into serious internal bleeding episodes. Bleeding disorders include things like acquired platelet function defects, disseminated intravascular coagulation (DIC), prothrombin deficiency, hemophilia C, Glanzmann disease, idiopathic thrombocytopenic purpura (ITP), and Von Willebrand disease.

    Ectopic pregnancy happens when a fertilized egg gets stuck on its way to the uterus. Usually, this egg will be stuck in the fallopian tube. If a fallopian tube ruptures inside the body, it can cause internal bleeding. [19]
    • Other ectopic pregnancy symptoms include severe abdominal pain, vaginal bleeding, shoulder pain, vomiting, diarrhea, and lightheadedness. Seek medical attention immediately if you are experiencing these symptoms.
    • Reader Poll: We asked 232 wikiHow readers and 59% of them agreed that they would immediately seek emergency medical care if they suspected an ectopic pregnancy. [Take Poll]

    If you recently had a surgery, your surgeon likely stopped all the bleeding inside your body before they completed the operation. However, if they missed something or your stitches ruptured, you may continue to bleed internally. [20]

    Angiography is a special imaging test that can examine individual blood vessels. During this test, the area will be numbed and your doctor will insert a catheter into an artery in your body. They will use a dye to color your arteries and blood vessels, and then they’ll take images of the vessels to see which ones (if any) are damaged. [23]

    For mild internal bleeding that isn’t life-threatening, medical treatment may not be needed. Instead, your doctor may recommend rest and relaxation to let your body stop the bleeding on its own. Your doctor will make this decision based on the severity of the bleeding and your medical history. [24]
