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.
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.
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.
[43] [44] [45] Causes of the reduced blood flow can include changes in the systemic circulation (e.g. low blood pressure), or local factors such as constriction of blood vessels or a blood clot. In most cases, no specific cause can be identified. [46] Ischemic colitis is usually suspected on the basis of the clinical setting, physical ...
One of the challenges is that symptoms of stroke in women have a number of overlapping symptoms with migraine. For example, both severe migraine and stroke may cause vision changes and dizziness.
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.
"Medical bleeding" denotes hemorrhage as a result of an underlying medical condition (i.e. causes of bleeding that are not directly due to trauma). Blood can escape from blood vessels as a result of 3 basic patterns of injury: [citation needed] Intravascular changes — changes of the blood within vessels (e.g. ↑ blood pressure, ↓ clotting ...
