The study revealed several key findings: First, the stomach exhibited periodic contractions when empty, occurring approximately every 30 to 90 seconds. Second, these contractions strongly correlated with Washburn's reported feelings of hunger, suggesting a direct link between stomach activity and the subjective experience of hunger.
The physical sensation of hunger is related to the contractions of the muscles of the empty stomach. Peristalsis takes place even when the stomach is empty, and these contractions—sometimes called hunger pangs once they become severe—are believed to be triggered by high concentrations of the ghrelin hormone.
The presence of bright red blood in stool, known as hematochezia, typically indicates lower gastrointestinal bleeding. Digested blood from the upper gastrointestinal tract may appear black rather than red, resulting in "coffee ground" vomit or melena.

Gastroparesis (gastro- from Ancient Greek γαστήρ – gaster, "stomach"; and -paresis, πάρεσις – "partial paralysis") is a medical disorder of ineffective neuromuscular contractions (peristalsis) of the stomach, resulting in food and liquid remaining in the stomach for a prolonged period of time.
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. The initial assessment includes measurement of the blood pressure and heart rate, as well as blood tests to determine the hemoglobin.
