Symptoms

Signs and symptoms of GI bleeding can be either obvious (overt) or hidden (occult). Signs and symptoms depend on the location of the bleed, which can be anywhere on the GI tract, from where it starts — the mouth — to where it ends — the anus — and the rate of bleeding.

Overt bleeding might show up as:

• Vomiting blood, which might be red or might be dark brown and resemble coffee grounds in texture
• Black, tarry stool
• Rectal bleeding, usually in or with stool

With occult bleeding, you might have:

• Lightheadedness
• Difficulty breathing
• Fainting
• Chest pain
• Abdominal pain

Symptoms of shock

If your bleeding starts abruptly and progresses rapidly, you could go into shock. Signs and symptoms of shock include:

• Drop in blood pressure
• Not urinating or urinating infrequently, in small amounts
• Rapid pulse
• Unconsciousness

When to see a doctor

If you have symptoms of shock, you or someone else should call 911 or your local emergency medical number. If you're vomiting blood, see blood in your stools or have black, tarry stools, seek immediate medical care. For other indications of GI bleeding, make an appointment with your doctor.
