What Is Gastrointestinal (GI) Bleeding?

Gastrointestinal (GI) bleeding simply means bleeding somewhere within the body where the food travels after you eat. That means from your mouth to your backside (anus). There are two types: one occurs in the upper, such as your stomach, and the other in the lower, such as your intestines. This can occur due to sores, swelling, germs, or even something more severe like cancer. Let us learn more about the cause of such bleeding and how we can manage it.

What Are the Common Causes of Gastrointestinal Bleeding?

Common Causes of Upper GI Bleeding

• Peptic Ulcers – These are like small holes or sores in the lining of your stomach that can bleed.

• Esophageal Varices – These are enlarged veins within the tube that food is transported to your stomach, and sometimes they may rupture and bleed.

• Gastritis – This refers to the lining of your stomach becoming red and inflamed, somewhat like a rash, and can lead to bleeding.

• Mallory-Weiss Tears – These are tiny cuts in the food tube close to your stomach that can occur from vomiting too forcefully.

Common Causes of Lower GI Bleeding

• Diverticulosis – Small pouches can grow in the walls of your intestines, and occasionally, they become sore or bleed.

• Hemorrhoids – These are inflamed veins around your bottom that can ache or bleed during a bowel movement.

• Colorectal Polyps or Cancer – Small bumps may grow inside your intestines, and some may develop into something serious, such as cancer, and lead to bleeding.

• Inflammatory Bowel Disease (IBD) – This is when the lining of your intestines becomes inflamed and irritated frequently, which can cause pain and bleeding.

What Are the Symptoms of GI Bleeding?

• Vivid red blood on the stool or toilet paper.

• Black, tarry stools (melena).

• Vomiting blood (hematemesis).

• Fatigue or weakness.

• Shortness of breath.

• Abdominal pain.

• Iron-deficiency anemia.

If you develop any of these signs, it is important to speak with a gastroenterologist right away.

When Should You See a Gastroenterologist for GI Bleeding?

If you continue to have abdominal pain that is not subsiding, it would be a good idea to visit a doctor. You should also seek assistance if you notice blood after using the restroom or if you are losing weight unintentionally. These may be indicators that something is wrong within your body.

What Are the Diagnostic Tests Used to Detect GI Bleeding?

Blood Tests

• A blood test can show if you have lost a lot of blood or have anemia.

• It can also check how well your blood is clotting.

• If doctors think your liver might be involved, they will test that too.

Stool Tests

• A special stool test can find hidden blood that you cannot see.

Endoscopy

• A thin tube with a camera can look inside your upper or lower digestive system.

• Sometimes, just part of the lower part is checked with a shorter scope.

• You might even swallow a tiny camera in a capsule to check the small intestine.

Imaging Tests

• Scans like CTs (computed tomography) or X-rays help doctors see inside your belly to find where the bleeding is coming from.

• Some special scans can track bleeding using dyes or tiny tracers.

How Is Gastrointestinal (GI) Bleeding Treated?

Physicians treat GI bleeding by determining the cause and controlling the bleeding. Some of the ways they do this are as follows:

Endoscopy: Physicians insert a thin tube with a camera into your stomach or intestines. In the process, they can also: Stop bleeding from ulcers, remove small polyps, and administer medicine directly to the bleeding site.

Medications: Certain medications can control or stop the bleeding:

• PPIs (Proton Pump Inhibitors) – These decrease stomach acid and promote the healing of ulcers.

• Reversal Agents – These are taken if you are on blood thinners and bleeding too much.

• Antibiotics – These are taken if the infection is causing the bleeding.

Surgery: If the bleeding is extremely severe and other GI bleeding treatments do not help, surgery may be necessary to correct the issue.

Supportive Care: As doctors treat the bleeding, they also take care of your body:

• IV (Intravenous) Fluids - To keep you hydrated and support blood pressure.

• Oxygen – If your blood lacks sufficient oxygen, you might receive additional oxygen to assist.

• Monitoring – Nurses and physicians closely monitor your vital signs, blood counts, and how much you urinate to ensure you remain stable.

What Are the Tips to Prevent GI Bleeding?

• To help prevent gastrointestinal (GI) bleeding, it is important to be kind to your digestive system.

• Do your best to stay away from overusing pain medicines such as Ibuprofen or Naproxen, and avoid excessive drinking of alcohol, as both can damage your stomach lining.

• Staying away from smoking is also a great help since smoking itself can cause ulcers and tends to make a person bleed.

• Healthy eating, regular exercise, and maintaining a healthy weight are all excellent ways to help your gut health.

• If you already have conditions with GI problems, ensure that you stick to what your doctor advises to help manage them.

• A diet high in fiber can also assist with issues such as constipation and reduce your risk of bleeding.

What Foods to Avoid if You Have GI Bleeding?

• Sour Foods: Pickles, lemons, and mangoes are very acidic and can make stomach ulcers worse.

• Fast Food: Foods like sausages and bacon have little nutrition and can hurt your intestines over time.

• Fatty Foods: Fried items like chips and fried chicken can cause bloating and are hard to digest.

• Spicy Foods: Chili, curry, and pepper can irritate your stomach and cause bleeding.

• Soft Drinks and Stimulants: Soda, alcohol, and coffee can result in stomach problems and increase bleeding.
