Kino kikole kati¶

1. Call your local emergency number immediately if the person is vomiting blood, passing black tarry stools with dizziness, or bleeding heavily from the rectum. Dial 911 in the United States and Canada, 112 across the European Union, 999 in the United Kingdom, or see all ennamba z’amangu. Tell the dispatcher whether the patient is vomiting bright red blood, has liver cirrhosis, or takes blood thinners (anticoagulants), as this triggers advanced paramedic airway and blood-transfusion protocols.
2. Protect the airway by placing any vomiting or drowsy person on their side (Recovery Position). If the person is actively vomiting blood (hematemesis), retching, or becoming drowsy, confused, or unconscious, immediately roll them onto their left side into the lateral recovery position and tilt their chin slightly downward so blood and clots drain freely out of the corner of their mouth into a basin or towel. Use a finger wrapped in a cloth to sweep any large rubbery blood clots out of the front of their mouth if they are gagging.
3. Lay a non-vomiting, dizzy person flat on their back to prevent fainting and shock. Do not allow a person with suspected GI bleeding to walk down stairs, stand at the bathroom sink, or sit upright on the toilet if they feel lightheaded. Standing upright when blood volume is depleted causes blood pressure to plummet (orthostatic syncope), leading to sudden collapse, severe head injuries on bathroom tiles, and cardiac arrest. If they are fully alert and not nauseated or vomiting, lay them flat on the floor or bed.
4. Give strictly NOTHING by mouth (no water, no milk, no antacids, and never aspirin or NSAIDs). Do not let the person drink water, milk, or herbal teas, and do not give oral antacids or bismuth. Most importantly, never give aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve), diclofenac, or ketorolac for stomach pain: these nonsteroidal anti-inflammatory drugs (NSAIDs) strip away the stomach's protective mucus barrier and paralyze blood platelets, turning a slow ulcer bleed into a torrential arterial hemorrhage.
5. Keep the person warm with blankets to protect blood clotting. Cover the patient with a warm blanket or coat and place a blanket underneath them if they are lying on a cold bathroom floor. When a bleeding patient becomes cold (hypothermia below \(35^\circ\text{C}\) or \(95^\circ\text{F}\)), the enzymatic clotting cascade and blood platelets stop working properly (part of the "Lethal Triad of Trauma and Hemorrhage"), causing uncontrollable bleeding.
6. Save a sample or take a smartphone photo of the vomit or stool, and gather all medication bottles. Before flushing the toilet or throwing away a basin of vomit, snap a clear photograph with your phone or save the container to show paramedics (doctors need to see the exact color, clots, and estimated volume). Gather every prescription and over-the-counter bottle in the house, specifically checking for blood thinners (warfarin, apixaban, rivaroxaban, dabigatran, clopidogrel), aspirin/NSAIDs, steroids, and iron or bismuth supplements.

Decoding the 4 visual patterns of GI bleeding: What color tells you¶

As blood travels through the human digestive tract, stomach hydrochloric acid, digestive enzymes (pepsin), and intestinal bacteria chemically alter the red hemoglobin molecule inside red blood cells, changing its color from bright crimson to dark brown-black. By looking closely at what was vomited or passed into the toilet, you can pinpoint where the bleeding is coming from and how fast it is happening.

False alarms: Distinguishing real blood from harmless food and pill staining ("Pseudomelena")¶

Before panicking over a dark or reddish stool in someone who feels completely healthy, has a normal pulse, and has zero dizziness or stomach pain, check whether they consumed one of these common mimics in the past 24 to 48 hours:

• Harmless mimics of Black Melena ("Pseudomelena"):
• Oral Iron Supplements (ferrous sulfate, ferrous gluconate, prenatal vitamins): Turns stool a dark greenish-black color, but the stool has a normal firm shape (not sticky tar) and lacks the putrid odor of digested blood.
• Bismuth Subsalicylate (Pepto-Bismol, Kaopectate): Bismuth reacts with trace sulfur in saliva and the gut to form black bismuth sulfide, often turning both the tongue and the stool jet-black.
• Activated Charcoal, black licorice, dark chocolate/Oreo cookies, or large bowls of dark blueberries/grape juice.
• Harmless mimics of Red Hematochezia / Red Vomit:
• Red beets (beetroot / betanin pigment), red gelatin (Jell-O), Kool-Aid / red sports drinks, red food coloring, dragon fruit, or large amounts of tomato sauce.
• Safety Rule: If there is any doubt whatsoever, or if the person has stomach pain, weakness, sweating, or takes aspirin/blood thinners, always treat it as real blood and go to the emergency room (a 30-second hospital fecal occult blood test or hemoglobin fingerstick settles the question immediately).

Major causes of upper and lower gastrointestinal bleeding¶

Understanding what causes GI bleeding helps you give critical medical history to the paramedics and emergency physicians.

1. Upper GI bleeding causes (75% to 80% of all hospital GI bleed admissions)¶

• Peptic Ulcer Disease (Gastric and Duodenal Ulcers: 40% to 50% of upper bleeds): Deep sores eroded into the lining of the stomach or the first part of the small intestine (duodenum), almost always caused by either Helicobacter pylori (H. pylori) bacterial infection or regular use of NSAID painkillers (ibuprofen, naproxen, aspirin, meloxicam, diclofenac). When an ulcer eats down into the submucosa and erodes the wall of a major artery (such as the gastroduodenal artery behind the duodenum or the left gastric artery), blood spurts under high arterial pressure into the gut.
• Esophageal and Gastric Varices (10% to 20% of upper bleeds, highest mortality): In patients with liver cirrhosis (from alcohol use, hepatitis B or C, or fatty liver disease) or portal vein thrombosis, scar tissue in the liver blocks normal blood flow from the intestines. Pressure backs up in the portal vein (portal hypertension), forcing blood to detour through fragile, thin-walled veins lining the lower esophagus and upper stomach (varices), which swell like varicose veins. When a varix ruptures, it causes painless, explosive projectile vomiting of hundreds of milliliters of bright red blood and carries a 15 to 20 percent mortality rate per bleeding episode.
• Mallory-Weiss Tear (5% to 15% of upper bleeds): A longitudinal laceration (tear) in the mucous membrane at the junction where the esophagus meets the stomach, triggered by violent retching, dry heaving, or forceful vomiting (after heavy alcohol binge drinking, food poisoning, hyperemesis gravidarum in pregnancy, or severe coughing fits). Typically starts with several episodes of normal vomit followed suddenly by bright red blood.
• Erosive Gastritis, Esophagitis, and Dieulafoy Lesion: Diffuse pinpoint bleeding from severe acid reflux, alcohol, critical illness stress, or a Dieulafoy lesion (an abnormally large, tortuous submucosal artery in the upper stomach that erodes through a tiny mucosal defect and causes massive sudden bleeding without an ulcer).

2. Lower GI bleeding causes (Colon, Rectum, and Small Bowel)¶

• Okuvaamu omusaayi mu ngeri ey’enjawulo (Diverticulosis: 30% to 50% of brisk lower bleeds): Obulwadde obutono obulinga ensawo (diverticula) mu bbugwe w’ebinywa by’ekyenda ekinene, obutera okubeera mu bantu abakulu abasukka emyaka 50, bubaawo wennyini awali emisuwa gy’ebiriisa egiyingira (vasa recta) gye gifumita ekisenge ky’ekyenda ekinene. Singa omusuwa vasa recta munda mu diverticulum gwakutuka, kireeta okuyita okw’amangu, okutaliimu bulumi bwonna kw’omusaayi omungi ogwa maroon oba omumyufu omutangaavu n’okuzimba mu kaabuyonjo.
• Angiodysplasia (Vascular Ectasias): Ebizimba ebigonvu, ebikyuse eby’emisuwa n’emisuwa ebigaziye mu bbugwe w’ekyenda ekinene ekya ddyo oba ekyenda ekitono, ebitera okubeera mu bantu abakulu, abalwadde abalina obulwadde bw’ekibumba obutawona, oba abalwadde abalina obulwadde bw’okusannyalala kw’omusuwa (Heyde’s syndrome).
• Ischemic Colitis, Inflammatory Bowel Disease (Ulcerative Colitis / Crohn’s Disease), ne Infectious Colitis: Okwawukanako n’okuvaamu omusaayi mu diverticular (ekitera obutalumwa), embeera zino zireeta obulumi mu lubuto olwa wansi obuzimba nga bugatta n’ekiddukano ekivaamu omusaayi oba omusulo.
• Colorectal Polyps ne Kookolo w’omumwa gwa nnabaana: Ebiseera ebisinga bireeta okukulukuta mpola, okutambula obutasalako ekivaako okukendeera kw’omusaayi olw’obutaba na kyuma, oba emiguwa egy’emmyufu enzirugavu egitabula mu lugoye lw’omusulo.
• Hemorrhoids and Anal Fissures: Swollen veins in the anal canal (hemorrhoids) or a sharp tear in the anal lining (fissure, which feels like "passing broken glass" during a bowel movement) typically coat the outside of the stool or drip bright red blood onto the toilet paper after wiping.

Recognizing hypovolemic shock: Why normal blood pressure can be a lie¶

An average adult body holds roughly 5,000 milliliters (5 liters / 10.5 pints) of blood. When a person bleeds into their stomach or colon, the body immediately unleashes a rush of adrenaline to constrict blood vessels and speed up the heart, which keeps systolic blood pressure looking deceptively normal until the patient has already lost 30 percent (1.5 liters) of their blood.

Use the American College of Surgeons Advanced Trauma Life Support (ATLS) hemorrhage classification to recognize early shock before blood pressure crashes:

Critical warnings: Liver cirrhosis, blood thinners, and aortoenteric fistula¶

If the bleeding person belongs to any of these three high-risk groups, inform the 911 / 112 / 999 dispatcher and paramedics in your very first sentence:

1. Known or Suspected Liver Disease / Cirrhosis (Variceal Bleed): Look for yellow eyes/skin (jaundice), a swollen fluid-filled belly (ascites), spider-like red blood vessels on the chest (spider angiomata), or red palms (palmar erythema). Variceal hemorrhage requires immediate hospital intravenous terlipressin or octreotide (to lower portal vein pressure), prophylactic IV antibiotics (ceftriaxone), and emergency endoscopic variceal band ligation within 12 hours.
2. Patients Taking Anticoagulants ("Blood Thinners") or Dual Antiplatelet Therapy: Check if the patient takes warfarin (Coumadin), Direct Oral Anticoagulants (apixaban [Eliquis], rivaroxaban [Xarelto], edoxaban [Savaysa], dabigatran [Pradaxa]), or antiplatelets (clopidogrel [Plavix], prasugrel, ticagrelor, aspirin). Hospital emergency departments carry specific intravenous reversal antidotes (4-factor Prothrombin Complex Concentrate [Kcentra/Beriplex] + IV Vitamin K for warfarin; andexanet alfa for apixaban/rivaroxaban; idarucizumab [Praxbind] for dabigatran) that can stop fatal bleeding if the medical team knows which pill the patient takes and when the last dose was swallowed.
3. Prior Abdominal Aortic Aneurysm (AAA) Graft Surgery ("Herald Bleed" of an Aortoenteric Fistula): If a person who has ever had an open or endovascular surgical graft placed on their abdominal aorta develops any gastrointestinal bleed (even a small, self-stopping episode of hematemesis or melena), it is a surgical emergency until proven otherwise. A synthetic aortic graft can slowly erode into the wall of the adjacent third part of the duodenum, creating an aortoenteric fistula; a small "herald bleed" is often followed hours or days later by catastrophic, fatal exsanguination directly from the aorta into the gut unless repaired in the operating room.

Ebintu eby’enjawulo ebirina okulowoozebwako: Okuvaamu omusaayi mu baana mu GI n’okumira bbaatule ya button¶

Omwana omuwere, omwana omuto oba omukulu bw’asesema omusaayi oba ng’ayita mu musulo omuddugavu oba ogulimu omusaayi, byombi ebivaako n’ebipimo by’obungi bw’omusaayi ebikulu byawukana nnyo ku bantu abakulu.

3. Endoscopic Hemostasis, Interventional Radiology, or Balloon Tamponade: Within 12 to 24 hours (or immediately after airway intubation in unstable patients), a gastroenterologist passes a flexible fiber-optic esophagogastroduodenoscope (EGD) down the throat to locate the bleeding vessel and seal it using metal hemoclips, thermal multipolar electrocoagulation, epinephrine injection, hemostatic powder spray (Hemospray), or elastic variceal rubber band ligation. If bleeding cannot be stopped endoscopically, interventional radiologists perform transcatheter arterial embolization (TAE) (threading a microcatheter through the femoral or radial artery to plug the bleeding branch with coils) or place a transjugular intrahepatic portosystemic shunt (TIPS) for refractory varices.
