There are a few things that you can look out for if you suspect that you might have GI or rectal bleeding. Your stool might become darker, like coal tar, if the bleeding is coming from the stomach or upper GI tract. You may pass blood from your rectum during bowel movements, which could cause you to see some blood in your toilet or on your toilet tissue. This blood is usually bright red in color. Vomiting blood is another sign that there is bleeding somewhere in your GI tract.
If you see any of these symptoms or if you have vomit that looks like coffee grounds, call your doctor immediately. GI bleeding could signal a potentially life-threatening condition, and prompt medical treatment is essential. Seek treatment immediately if you experience paleness, weakness, or shortness of breath. These could be signs of severe bleeding.
