NAUSEA AND VOMITING:
DIAGNOSTIC WORKUP
(Algorithmic Diagnosis of Symptoms and Signs)
The basic workup includes a CBC, sedimentation rate, urinalysis, urine drug screen, chemistry panel and electrolytes, serum amylase, arterial blood gases, stools for occult blood, chest x-ray, EKG, and flat plate of the abdomen. Acute onset of nausea and vomiting with ataxia requires an immediate CT scan of the brain to rule out a cerebellar hemorrhage. A pregnancy test should be routine in women of child-bearing age. If there is fever, febrile agglutinins and a heterophile antibody titer should be done. If there is an abdominal mass, a gallbladder ultrasound and intravenous pyelogram may need to be done. Isotope scanning with iminodiacetic acid derivatives is extremely useful to detect acute cholecystitis. If there is chronic vomiting and abdominal pain, the diagnosis can often be made with an upper GI series, small bowel series, or barium enema.
When there is persistent vomiting with abdominal pain, an exploratory laparotomy may need to be considered. The presence of an abdominal mass or suspected pancreatic or biliary disease merits consideration of a CT scan. However, before ordering expensive diagnostic tests, a general surgeon or gastroenterologist ought to be consulted. Laparoscopy, gastroscopy, esophagoscopy, duodenoscopy, and colonoscopy all need to be considered in the workup. Gastroparesis and intestinal pseudo-obstruction can be ruled out by radioisotope studies and manometry of the stomach and small intestine. Angiography is useful to diagnose mesenteric artery ischemia.

Nausea:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
Begin by obtaining a complete medical history. Focus on GI, endocrine, and metabolic disorders; recent infections; and cancer and its treatment. Ask about drug use and alcohol consumption. If the patient is a female of childbearing age, ask if she is or could be pregnant. Have the patient describe the onset, duration, and intensity of the nausea as well as what causes or relieves it. Ask about related complaints, particularly vomiting (color, amount), abdominal pain, anorexia and weight loss, changes in bowel habits or stool character, excessive belching or flatus, and a sensation of bloating.
Inspect the skin for jaundice, bruises, and spider angiomas, and assess skin turgor. Next, inspect the abdomen for distention, auscultate for bowel sounds and bruits, palpate for rigidity and tenderness, and test for rebound tenderness. Palpate and percuss the liver for enlargement. Assess other body systems as appropriate.

Nausea and Vomiting:
Physical examination.
(The 10-Minute Diagnosis Manual: Symptoms and Signs in the Time-Limited Encounter)
A directed physical examination is dictated by the findings on history, but the following are areas of key importance:
A. Vital signs. Focus on presence of fever, pulse, and blood pressure to assess hydration, and respiratory rate to look for acidosis-related hyperventilation.
B. Skin, eyes, mucous membranes. Look for dehydration and signs of jaundice.
C. Signs of systemic infection. Pay special attention to examining the lung and the costovertebral angle for tenderness.
D. A detailed abdominal examination should include inspection, auscultation, palpation, percussion, areas of tenderness, rebound, guarding, hepatomegaly, Murphy’s sign, stool for occult blood, and bimanual pelvic examination.
Testing.
Most cases of nausea and vomiting seen in a generalist’s office will not require laboratory testing. If the diagnosis is still unclear after history and physical examination, the laboratory workup can be classified into primary, secondary, and tertiary on the basis of their utility and ability to detect disease with an urgent need for diagnosis.
A. Primary tests include electrolytes, glucose, renal and liver function tests, amylase, urinalysis, stool for white blood cells, pregnancy test, and plain films of the abdomen or abdominal ultrasound if pain is a prominent feature of the presentation.
B. Secondary tests include abdominal ultrasound if not already done, upper GI series or upper endoscopy, stool culture, thyroid-stimulating hormone, electrocardiogram, and chest x-ray study.
C. Tertiary tests include lower endoscopy, computed tomography or magnetic resonance imaging studies, urine toxicology, urine porphyrins, and, in many instances, specialty consultation.
Diagnostic assessment
The diagnostic assessment of nausea and vomiting will benefit from a structured approach that includes the following:
A. A differential diagnosis based on age and reproductive status.
B. Attention to GI versus systemic causes of nausea and vomiting.
C. Special attention to the potentially more urgent nature of cases of nausea and vomiting that are often accompanied by abdominal pain (Chapter 9.1).

Nausea/Vomiting:
Diagnostic Approach
(Field Guide to Bedside Diagnosis)
Neurological vomiting may be projectile (forceful emesis without prior nausea), positional, or associated with other neurological signs. Central vomiting (chemoreceptor trigger zone stimulation, usually caused by toxins) is alleviated by antidopaminergic medications, which do not work well when treating nausea due to mechanical causes such as obstruction.
Early morning nausea suggests pregnancy or metabolic causes (e.g., uremia). Vomiting of a large amount of undigested food 4 to 6 hours after eating is consistent with gastric retention resulting from pyloric obstruction
or gastroparesis or to esophageal disorders such as achalasia or Zencker diverticulum. Feculent vomiting suggests intestinal obstruction or gastrocolic fistula.
