Hyperbilirubinemia means an elevated level of bilirubin in the blood. Bilirubin is a yellow pigment produced when the body breaks down old red blood cells. Hyperbilirubinemia is commonly discussed when evaluating jaundice (yellowing of the skin and eyes). It is used in clinical medicine as a laboratory and diagnostic concept in hepatology and gastroenterology.

Jaundice is a yellow discoloration of the skin and the whites of the eyes caused by elevated bilirubin in the blood. It is a clinical sign, not a diagnosis. Jaundice is commonly discussed in gastroenterology, hepatology, pediatrics (newborns), and general medicine. Clinicians use it as a visible clue to disorders involving the liver, bile ducts, gallbladder, pancreas, or red blood cell breakdown.

Left Lower Quadrant Pain describes pain felt in the lower-left area of the abdomen. It is a symptom label, not a diagnosis. Clinicians use it in history-taking, physical exams, and medical documentation. It helps narrow which organs and conditions are most relevant to consider.

Right Upper Quadrant Pain describes discomfort felt in the upper right portion of the abdomen. It is a symptom label used to organize a patient’s history and guide a focused exam and workup. Clinicians commonly use it when considering liver, gallbladder, bile duct, and nearby gastrointestinal causes. It also helps communicate location consistently across teams (emergency medicine, surgery, gastroenterology).

Epigastric Pain is pain or discomfort felt in the upper middle part of the abdomen. It is commonly described as pain “just below the breastbone” or “in the pit of the stomach.” Clinicians use the term to localize symptoms and narrow the differential diagnosis. It is discussed frequently in gastroenterology, hepatology, emergency care, and primary care.

Abdominal Pain is discomfort or pain felt between the lower ribs and the pelvis. It is a symptom, not a diagnosis, and it can arise from digestive, urinary, reproductive, vascular, or abdominal wall causes. Clinicians use it as a starting point to describe a patient’s complaint and guide evaluation. It is also used in teaching and documentation to localize disease and track changes over time.

Flatulence is the passage of intestinal gas through the rectum and anal canal. In plain terms, it is “passing gas” or “farting.” In clinical settings, Flatulence is discussed as a symptom related to digestion, gut motility, and the intestinal microbiome. It is commonly described alongside bloating, abdominal discomfort, and changes in bowel habits.

Bloating is a symptom described as an uncomfortable feeling of fullness, tightness, or “pressure” in the abdomen. Some people mean a visible increase in abdominal size, while others mean a sensation without obvious distension. It is commonly used in gastroenterology clinics, primary care, and emergency settings as a starting point for symptom evaluation. In teaching and documentation, it is often discussed alongside gas, bowel habits, diet, and abdominal pain.

Gastroparesis is delayed emptying of stomach contents into the small intestine. It happens without a physical blockage (obstruction) causing the delay. It is used clinically as a diagnosis to explain chronic nausea, vomiting, early fullness, and poor intake. It is most commonly discussed in gastroenterology, endocrinology, and GI surgery settings.

Dyspepsia is a clinical term for a group of upper abdominal symptoms centered in the epigastrium. It commonly includes bothersome fullness after meals, early satiety, epigastric pain, or epigastric burning. Dyspepsia is used in outpatient clinics, emergency settings, and inpatient consults to frame evaluation of “indigestion.” It describes symptoms, not a single diagnosis.
