A Hyperplastic Gastric Polyp is a common, usually benign growth that forms on the lining of the stomach. It develops from “reactive” (repair-type) changes in the stomach’s mucosa, often in the setting of chronic inflammation. Clinicians most often identify it during upper endoscopy performed for symptoms or anemia workups. It matters because it can bleed, coexist with other gastric conditions, or rarely contain precancerous change.

A Fundic Gland Polyp is a small growth that arises from the acid-secreting gland lining of the stomach. It is most often found in the gastric fundus and body during upper endoscopy. Many are discovered incidentally when endoscopy is performed for common upper gastrointestinal symptoms.

Gastric Polyps are raised lesions that project from the lining of the stomach. They are usually found during upper endoscopy performed for symptoms or screening. Most are benign, but some have dysplasia (precancer) or cancer risk depending on type. Clinicians use biopsy and histology (microscopic diagnosis) to classify them.

Folate Deficiency is a state of inadequate folate (vitamin B9) available for normal body functions. It is most commonly discussed in relation to anemia, pregnancy-related risk, and malabsorption disorders. In gastroenterology and hepatology, it often signals problems with nutrition, small-intestinal absorption, or chronic illness. It is also a frequent “secondary finding” during evaluation of macrocytosis (enlarged red blood cells).

B12 Deficiency is a clinical state in which the body has inadequate vitamin B12 (cobalamin) for normal function. It is commonly discussed when evaluating anemia, neurologic symptoms, and malabsorption in gastrointestinal (GI) practice. Vitamin B12 is essential for red blood cell production and normal nerve function. In gastroenterology and hepatology, B12 Deficiency often points to problems with stomach or ileal (terminal small bowel) physiology.

Microcytic Anemia means anemia with smaller-than-usual red blood cells. It is most often identified on a complete blood count (CBC) by a low mean corpuscular volume (MCV). Clinicians use it as a clue to narrow the differential diagnosis of anemia. It commonly appears in primary care, gastroenterology, hematology, and perioperative evaluation.

Macrocytic Anemia is anemia in which red blood cells are larger than expected. It is commonly identified on a complete blood count (CBC) using the mean corpuscular volume (MCV). It is a clinical pattern, not a single disease. It is frequently discussed in gastroenterology because digestion and absorption problems can cause vitamin deficiencies that lead to it.

Iron Deficiency Anemia is anemia caused by insufficient iron to support normal red blood cell production. It commonly presents with fatigue, reduced exercise tolerance, or no symptoms at all. In gastroenterology, it is frequently discussed as a clue to chronic blood loss or impaired iron absorption in the gastrointestinal (GI) tract. It is used as both a diagnostic label and a starting point for evaluating underlying causes.

Occult GI Bleeding means blood loss from the gastrointestinal (GI) tract that is not visible to the naked eye. It is usually suspected when a stool test detects hidden blood or when lab tests show iron deficiency anemia. It is a clinical concept used in primary care, emergency medicine, and gastroenterology to guide evaluation. It helps clinicians look for GI sources of chronic, low-volume bleeding.

The Bristol Stool Chart is a visual scale that classifies stool into seven types based on shape and consistency. It translates a subjective symptom into a standardized description that can be shared across clinicians and patients. It is commonly used in gastroenterology clinics, primary care, and inpatient settings. It is also used in research to compare bowel patterns across groups.
