Upper Gastrointestinal Bleeding – A Patient‑Friendly Guide

Overview

Upper gastrointestinal (GI) bleeding refers to any bleeding that originates from the esophagus, stomach, or the first part of the small intestine (duodenum) and is seen either as vomiting of blood (hematemesis) or as black, tarry stools (melena). It is a medical emergency because the loss of blood can be rapid and life‑threatening.

While anyone can develop an upper GI bleed, the condition is most common in adults over 50, especially those with a history of peptic ulcer disease, chronic liver disease, or regular use of non‑steroidal anti‑inflammatory drugs (NSAIDs). In the United States, upper GI bleeding accounts for roughly 300,000 hospital admissions per year and a mortality rate of 5–10 % in high‑risk patients (NIH, 2022).

Symptoms

The presentation can range from subtle to dramatic. Common signs and symptoms include:

• Hematemesis – vomiting bright red blood or “coffee‑ground” material (partially digested blood).
• Melena – black, sticky, foul‑smelling stools indicating digested blood.
• Hematochezia – bright red blood per rectum (usually from a very brisk upper bleed).
• Abdominal pain – often epigastric, may be described as burning or gnawing.
• Feeling faint, weakness, or dizziness – due to blood loss and resultant low blood pressure.
• Rapid heart rate (tachycardia) – the heart compensates for reduced circulating volume.
• Shortness of breath – especially on exertion.
• Pallor – pale skin and mucous membranes.
• Cold, clammy skin – a sign of shock.
• Confusion or altered mental status – severe anemia or hypovolemia affecting brain perfusion.

Symptoms may be intermittent, especially if the bleeding has stopped temporarily and then re‑starts.

Causes and Risk Factors

Common Causes

• Peptic ulcer disease – the most frequent cause (≈50 %). Ulcers can erode a blood vessel as they dig deeper.
• Gastroesophageal reflux disease (GERD) with erosive esophagitis – severe acid exposure can cause mucosal tears.
• Esophageal varices – swollen veins in the esophagus due to portal hypertension (often from cirrhosis).
• Gastric or duodenal erosions – caused by NSAIDs, aspirin, or steroids.
• Mallory‑Weiss tear – longitudinal mucosal lacerations after forceful vomiting or retching.
• Gastric cancer or duodenal tumors – rare but important to consider.
• Dieulafoy lesion – an abnormally large submucosal artery that can erode the overlying mucosa.

Risk Factors

• Chronic NSAID, aspirin, or anticoagulant (warfarin, DOACs) use.
• History of peptic ulcers or H. pylori infection.
• Alcohol abuse and liver cirrhosis (portal hypertension → varices).
• Smoking (impairs mucosal defenses).
• Older age (≥50 years) – gastric mucosa becomes more fragile.
• Severe stress or critical illness (e.g., ICU patients) – “stress‑related mucosal disease.”
• Genetic clotting disorders or thrombocytopenia.

Diagnosis

Prompt evaluation is essential to determine the source and severity of bleeding.

Initial Assessment

• Vital signs – blood pressure, heart rate, respiratory rate, oxygen saturation.
• Physical exam – look for pallor, abdominal tenderness, signs of chronic liver disease.
• Laboratory tests – CBC (hemoglobin/hematocrit), coagulation profile (INR/PT), serum electrolytes, BUN/creatinine (BUN often rises disproportionately with GI bleeding), liver function tests.

Endoscopic Evaluation

The gold‑standard test is an esophagogastroduodenoscopy (EGD), usually performed within 24 hours of presentation. It allows direct visualization of the mucosa, identification of the bleeding source, and immediate therapeutic intervention (e.g., injection, cautery, clipping).

Additional Imaging (when endoscopy is not feasible or is inconclusive)

• Contrast‑enhanced CT angiography – detects active extravasation.
• Radionuclide technetium‑99m labeled red blood cell scan – highly sensitive for low‑rate bleeding.
• Mesenteric angiography – both diagnostic and therapeutic (embolization).

Scoring Systems

Tools such as the Glasgow-Blatchford Score (GBS) help clinicians predict the need for intervention or transfusion and guide urgency of endoscopy.

Treatment Options

Treatment is aimed at stabilizing the patient, stopping the bleed, and preventing recurrence.

1. Initial Resuscitation

• Fluid replacement – isotonic crystalloids (e.g., normal saline) to restore intravascular volume.
• Blood transfusion – generally when hemoglobin <7 g/dL (or <8 g/dL in patients with cardiovascular disease). Target a hemoglobin 7–9 g/dL.
• Correction of coagulopathy – vitamin K, fresh frozen plasma, or prothrombin complex concentrate if INR is elevated; reverse DOACs when appropriate.

2. Pharmacologic Therapy

• Proton pump inhibitors (PPIs) – high‑dose IV omeprazole or pantoprazole 80 mg bolus then 8 mg/h infusion reduces bleeding from ulcers (Cleveland Clinic, 2023).
• Octreotide – IV infusion (50 µg bolus then 50 µg/h) for variceal bleeding; reduces portal pressure.
• Antibiotics – for cirrhotic patients with variceal bleeding (e.g., ceftriaxone 1 g daily) to prevent spontaneous bacterial peritonitis.
• H. pylori eradication therapy – triple or quadruple regimens when infection is present.

3. Endoscopic Therapy (performed during EGD)

• Thermal coagulation – heater probe or bipolar cautery.
• Injection therapy – epinephrine 1:10,000 solution to vasoconstrict.
• Mechanical clips – titanium clips close small arterial bleeds.
• Band ligation – first‑line for esophageal varices.
• Sclerotherapy – injection of sclerosant into variceal walls.

4. Radiologic & Surgical Interventions

• Trans‑arterial embolization – interventional radiology occludes bleeding vessel when endoscopy fails.
• Surgical resection or oversewing – reserved for refractory or massive hemorrhage not amenable to endoscopic/radiologic control.

5. Lifestyle and Long‑Term Medications

• Discontinue or replace NSAIDs/aspirin with safer alternatives (e.g., acetaminophen).
• Maintain PPI therapy for 4–8 weeks after ulcer bleeding, then taper based on risk.
• For variceal disease, initiate non‑selective beta‑blockers (propranolol or carvedilol) to lower portal pressure.

Living with Upper Gastrointestinal Bleeding

Medication Management

• Take PPIs exactly as prescribed; do not skip doses.
• Report any new use of over‑the‑counter pain relievers to your clinician.
• If you are on anticoagulants, never stop them without medical guidance.

Dietary Tips

• Eat small, frequent meals rather than large meals.
• Avoid spicy, acidic, or fried foods that may irritate the stomach lining.
• Limit alcohol intake – especially important for patients with portal hypertension.
• Stay hydrated; aim for 1.5–2 L of water daily unless fluid restriction is ordered.

Monitoring & Follow‑up

• Schedule repeat endoscopy 4–8 weeks after a bleeding ulcer to confirm healing.
• Annual review of liver disease status if varices were the source.
• Maintain an up‑to‑date medication list and share it with every healthcare provider.

Psychosocial Aspects

Bleeding episodes can be frightening. Consider joining support groups for patients with peptic ulcer disease or liver disease. Counseling or stress‑reduction techniques (mindfulness, gentle exercise) may improve overall gut health.

Prevention

• Eradicate H. pylori when infection is detected – reduces ulcer recurrence by up to 90 % (WHO, 2021).
• Use the lowest effective dose of NSAIDs and co‑prescribe a PPI if long‑term therapy is unavoidable.
• Screen and treat liver disease early; adhere to surveillance endoscopy for varices if you have cirrhosis.
• Limit alcohol (<2 drinks per day for men, <1 for women) and quit smoking.
• Maintain a healthy weight and manage comorbidities such as diabetes and hypertension.

Complications

If bleeding is not promptly controlled, serious complications can arise:

• Hypovolemic shock – dangerously low blood pressure, organ failure.
• Severe anemia – fatigue, cardiac strain, need for transfusion.
• Acute kidney injury due to low perfusion.
• Re‑bleeding – occurs in up to 20 % of ulcer bleeds within 30 days.
• Infection – especially in cirrhotic patients with variceal bleeding.
• Perforation – a rare but life‑threatening hole in the GI wall.
