Hematemesis is the vomiting of blood. [1] This is usually vomit that contains bright red blood. [2] Coffee ground vomiting is similar to hematemesis, but is distinct in not involving bright red blood. [3] Hematemesis must be differentiated from hemoptysis (coughing up blood) and epistaxis (nosebleed). [4] Both of these are more common conditions.
Blood may be observed in vomit or in altered form as black stool. Depending on the amount of the blood loss, symptoms may include shock. Upper gastrointestinal bleeding can be caused by peptic ulcers, gastric erosions, esophageal varices, and rarer causes such as gastric cancer.
Gastrointestinal bleeding can range from small non-visible amounts, which are only detected by laboratory testing, to massive bleeding where bright red blood is passed and shock develops. Rapid bleeding may cause syncope. [18] The presence of bright red blood in stool, known as hematochezia, typically indicates lower gastrointestinal bleeding ...
This increased pressure reduces venous return, thereby reducing lung-heart function, resulting in signs and symptoms of shock. [15] Many of the signs of obstructive shock are similar to cardiogenic shock, although treatments differ. Symptoms of obstructive shock include: Abnormal heart rhythms, often a fast heart rate. Reduced blood pressure.
Arsenic poisoning (or arsenicosis) is a medical condition that occurs due to elevated levels of arsenic in the body. [4] If arsenic poisoning occurs over a brief period of time, symptoms may include vomiting, abdominal pain, encephalopathy, and watery diarrhea that contains blood. [1]
These early symptoms can include diarrhea (which is often bloody), stomach cramps, mild fever, [10] or vomiting that results in dehydration and reduced urine. [9] HUS typically develops about 5–10 days after the first symptoms, but can take up to 3 weeks to manifest, and occurs at a time when the diarrhea is improving. [10]
A heart attack can cause symptoms such as: Chest pain that often radiates to your left shoulder, neck, or arm. Abdominal pain. Shortness of breath. Fatigue. Pressure or heaviness in your chest ...
[3] [2] Hypovolemic shock is a medical emergency; if left untreated, the insufficient blood flow can cause damage to organs, leading to multiple organ failure. [4] In treating hypovolemic shock, it is important to determine the cause of the underlying hypovolemia, which may be the result of bleeding or other fluid losses.
