7.3 Digestive, Urinary, Endocrine & Reproductive Systems + OB/Pediatrics

The digestive (gastrointestinal, or GI) system breaks down food, absorbs nutrients, and eliminates waste, running from the mouth through the esophagus, stomach, small intestine, large intestine (colon), and rectum, with the liver, gallbladder, and pancreas contributing digestive functions along the way. GI complaints are among the most common reasons patients seek care, making this vocabulary essential for interpreters across nearly every clinical setting.

High-Frequency GI Conditions

• Gastroesophageal reflux disease (GERD) — stomach acid repeatedly flows back into the esophagus, causing heartburn and, over time, esophageal irritation; distinct from occasional heartburn because of its chronic, recurring pattern.
• Peptic ulcer — an open sore in the lining of the stomach or the first part of the small intestine (duodenum), commonly caused by H. pylori bacterial infection or long-term NSAID use.
• Cirrhosis — permanent scarring of the liver from long-term damage (commonly chronic alcohol use or viral hepatitis), which progressively impairs the liver's ability to filter blood, produce proteins, and process nutrients.

The specialty for this system is gastroenterology, and for liver-specific disease, hepatology.

A Critical False Cognate: "Constipado"

Spanish-English interpreters must be alert to one of the field's most cited false-cognate traps: "constipado" in Spanish means "has a cold" or "nasal congestion," it does not mean "constipated." The correct Spanish term for constipated (bowel-related) is "estreñido/a." An interpreter who renders a patient's "estoy constipado" as "I am constipated" has introduced a GI symptom the patient never reported, while missing that the patient actually described a respiratory/cold symptom. This kind of literal, cognate-driven error is exactly what CoreCHI's terminology domain and the CHI performance exam are designed to catch, and it underscores why interpreters must learn healthcare vocabulary as its own system rather than relying on surface similarity between languages.

The Urinary (Renal) and Genitourinary System

The urinary system filters waste from the blood and removes it as urine. The kidneys filter blood through millions of tiny units called nephrons; the ureters carry urine to the bladder, which stores it until it exits through the urethra.

The specialty for kidney disease is nephrology; for urinary-tract and reproductive-organ conditions more broadly, urology. As with cardiovascular readings, any staged or numeric lab value tied to kidney function (such as a CKD stage or a creatinine level) must be rendered with the exact number and stage given, since treatment decisions, including dialysis timing, depend on precise tracking of these values over time.

The endocrine system is a network of glands, including the pancreas, thyroid, adrenal glands, and pituitary gland, that release hormones directly into the bloodstream to regulate metabolism, growth, and countless other functions. Endocrine terminology is dense with numeric precision requirements, because diagnosis and treatment revolve around specific lab values.

Diabetes and Thyroid Disease

Diabetes mellitus occurs when the body cannot properly regulate blood glucose (sugar). Type 1 diabetes is an autoimmune condition in which the pancreas produces little or no insulin, requiring lifelong insulin therapy. Type 2 diabetes involves insulin resistance and/or insufficient insulin production, often managed initially with lifestyle changes and oral medication before insulin becomes necessary. Providers monitor diabetes through blood glucose readings (a single-point-in-time measurement, in mg/dL) and A1C/HbA1c (a lab value reflecting average blood sugar over roughly the past three months, expressed as a percentage), two related but distinct numbers that an interpreter must never conflate, since a provider discussing "your A1C" is asking about a three-month trend, not today's reading.

Thyroid disease runs in two directions:

The specialty for this system is endocrinology.

Reproductive Health and Obstetrics (OB)

Reproductive and obstetric encounters bring their own dense, number-sensitive vocabulary. Prenatal care is organized into three trimesters, and providers track pregnancy using gravida (total number of pregnancies) and para (number of pregnancies carried to a viable delivery), for example, "gravida 3, para 2" describes a specific obstetric history that must be rendered with the exact numbers stated. Labor and delivery terminology includes contractions, dilation (measured in centimeters as labor progresses), and cesarean section (C-section), a surgical delivery, as distinct from vaginal delivery.

A Second Critical False Cognate: "Embarazada"

Another high-stakes false cognate belongs in this system: Spanish "embarazada" means "pregnant," not "embarrassed" (the correct Spanish term for embarrassed is "avergonzada/o"). This pairing is frequently cited in interpreter training because the consequence of an error runs in a clinically significant direction: confusing the two could cause a provider to miss that a patient is pregnant, or to misunderstand an unrelated emotional disclosure as a pregnancy statement.

Pediatric Context

Pediatric visits layer additional vocabulary onto whichever body system is involved: well-child visits (scheduled preventive checkups), immunizations (vaccines, often discussed by name and schedule), developmental milestones (expected skills at a given age), and growth percentiles (how a child's height/weight compares to a reference population, expressed as a specific number, such as "50th percentile"). As with adult numeric values, percentile and milestone-age figures must be interpreted exactly; rounding "the 15th percentile" to "a little small" removes clinically meaningful information from the encounter. The specialty here is obstetrics/gynecology (OB/GYN) for reproductive and pregnancy care and pediatrics for infant, child, and adolescent care.
