Symptoms and Signs – Differential Diagnosis of Vomiting
Vomiting is the vigorous ejection of gastrointestinal contents via the oral cavity. Vomiting, typically preceded by nausea, occurs due to a synchronized series of stomach muscular contractions and retrograde esophageal peristalsis. Vomiting, a prevalent indicator of gastrointestinal problems, also manifests in conjunction with fluid and electrolyte imbalances, infections, as well as metabolic, endocrine, labyrinthine, central nervous system (CNS), and cardiac disorders. It may also arise via pharmacological treatment, surgical intervention, or radiotherapy. Vomiting often starts during the first trimester of pregnancy; however, its later onset may indicate difficulties. It may also arise from stress, worry, pain, alcohol intoxication, excessive consumption of food, or the ingestion of unpalatable substances.
Medical History and Physical Assessment
Request your patient to elucidate the start, duration, and intensity of his emesis. What initiated the emesis? What causes it to diminish? If feasible, gather, assess, and examine the nature of the vomitus. Refer to V omitus: Characteristics and Causes. Investigate any related symptoms, namely nausea, abdominal discomfort, anorexia, weight reduction, alterations in bowel habits or stool consistency, excessive belching or flatulence, and sensations of bloating or fullness.
Vomiting: Attributes and Etiologies
Upon collecting a sample of the patient's vomitus, meticulously examine it for indications of the underlying condition. The following may be indicated by vomitus:
VOMITUS STAINED WITH BILE (GREENISH) Obstruction beneath the pylorus, resulting from a duodenal lesion
HEMORRHAGIC VOMITING Upper gastrointestinal bleeding (bright red may indicate gastritis or a peptic ulcer; dark red may suggest esophageal or gastric varices)
BROWN EMESIS WITH A FECAL AROMA Intestinal blockage or ischemia SCORCHING, ACERBIC EMESIS Excessive hydrochloric acid in gastric secretions COFFEE-GROUND EMESIS Hemolyzed blood from a gradually hemorrhaging gastric or duodenal lesion
UNDECOMPOSED NUTRIENTS Gastric outlet restriction due to gastric tumor or ulcer
Gather a medical history, documenting gastrointestinal, endocrine, and metabolic diseases, recent infections, and malignancies, including chemotherapy or radiation treatment. Inquire on present medicine usage and alcohol intake. Inquire whether the female patient of childbearing age is currently pregnant or could potentially be pregnant. Inquire about the contraceptive method she is utilizing. Examine the abdomen for distension, and use auscultation to detect bowel sounds and bruits. Examine for rigidity and soreness, and assess for rebound tenderness. Subsequently, palpate and percuss the liver to assess for enlargement. Evaluate additional bodily systems as necessary. During the examination, note that projectile vomiting without accompanying nausea may signify elevated intracranial pressure, a critical emergency. In the event of this occurrence in a patient with CNS injury, promptly assess his vital signs. Monitor for increased pulse pressure or bradycardia.
Etiological Factors
Adrenal insufficiency
Typical gastrointestinal manifestations of the illness encompass vomiting, nausea, anorexia, and diarrhea. Additional results encompass weakness, exhaustion, weight loss, bronzed skin, orthostatic hypotension, and a weak, irregular pulse.
Gastrointestinal Anthrax
Preliminary indications and manifestations following the consumption of tainted meat from an infected animal encompass vomiting, anorexia, nausea, and pyrexia. Clinical manifestations may advance to stomach discomfort, profuse hematochezia, and hematemesis.
Appendicitis
Vomiting and nausea may ensue or coincide with abdominal pain. Pain generally initiates as indistinct epigastric or periumbilical discomfort and swiftly escalates to intense, stabbing pain in the right lower quadrant. The patient exhibits a pronounced McBurney’s sign, characterized by intense pain and sensitivity upon examination approximately 2 inches (5 cm) from the right anterior superior iliac spine, along the line from that spine to the umbilicus. Commonly observed findings often encompass abdominal rigidity and tenderness, anorexia, constipation or diarrhea, cutaneous hyperalgesia, fever, tachycardia, and malaise.
Acute cholecystitis
Cholecystitis typically presents with nausea and mild vomiting accompanying significant right upper quadrant discomfort, which may spread to the back or shoulders. Accompanying findings consist of abdominal discomfort, perhaps stiffness and distention, fever, and diaphoresis.
Cholelithiasis
Nausea and vomiting occur alongside intense, unlocalized discomfort in the right upper quadrant or epigastric region following the consumption of fatty meals. Additional findings encompass abdominal discomfort and guarding, flatulence, belching, epigastric burning, pyrosis, tachycardia, and restlessness.
Cholera
Manifestations include emesis and sudden, profuse diarrhea. Significant loss of water and electrolytes results in thirst, weakness, muscle cramps, diminished skin turgor, oliguria, tachycardia, and hypotension. In the absence of therapy, mortality may ensue within hours.
Cirrhosis
Subtle initial indications and manifestations of cirrhosis generally encompass nausea and vomiting, anorexia, stomach discomfort, and either constipation or diarrhea. Subsequent observations including jaundice, hepatomegaly, and abdominal distension.
Electrolyte dysregulation
Disturbances such as hyponatremia, hypernatremia, hypokalemia, and hypercalcemia often induce nausea and vomiting. Additional consequences encompass arrhythmias, tremors, convulsions, anorexia, malaise, and weakness.
Escherichia coli O157:H7
The manifestations of this infection encompass emesis, watery or hemorrhagic diarrhea, nausea, pyrexia, and stomach cramping. Hemolytic uremic syndrome may occur in children under 5 years of age and the elderly, resulting in the destruction of red blood cells, which can ultimately lead to acute renal failure.
Gastrointestinal intoxication
Vomiting is a prevalent symptom of food poisoning, resulting from preformed toxins produced by bacteria commonly present in food, including Bacillus cereus, Clostridium, and Staphylococcus. Diarrhea and fever typically manifest as well.
Gastric carcinoma
This uncommon cancer may cause mild nausea, vomiting (perhaps of mucus or blood), anorexia, upper abdominal pain, and chronic dyspepsia. Fatigue, weight reduction, melena, and modified bowel habits are prevalent as well.
Gastritis
Nausea and the expulsion of mucus or blood are prevalent in gastritis, particularly following the consumption of alcohol, aspirin, spicy meals, or caffeine. Epigastric discomfort, eructation, and pyrexia may manifest.
Gastroenteritis
Gastroenteritis induces nausea, vomiting (often of undigested food), diarrhea, and abdominal discomfort. Fever, malaise, hyperactive bowel noises, stomach pain, and tenderness may also manifest
Cardiac insufficiency
Nausea and emesis may manifest, particularly in cases of right-sided heart failure. Related findings encompass tachycardia, ventricular gallop, tiredness, dyspnea, crackles, peripheral edema, and jugular vein distension.
Hepatitis
Vomiting frequently ensues sickness as an initial indication of viral hepatitis. Additional initial findings encompass tiredness, myalgia, arthralgia, headache, photophobia, anorexia, pharyngitis, cough, and fever.
Hyperemesis gravidarum
This pregnancy illness is characterized by persistent nausea and vomiting that extend beyond the first trimester. Vomitus contains undigested food, mucus, and minimal bile in the initial stages of the illness; thereafter, it has a coffee-ground look. Related findings encompass weight reduction, cephalalgia, and delirium.
Thyroid dysfunction may be linked to this disorder
Elevated intracranial pressure
Projectile vomiting occurring without prior nausea indicates elevated intracranial pressure. The patient may demonstrate diminished level of consciousness and Cushing's triad (bradycardia, hypertension, and alterations in breathing patterns). He may additionally experience cephalalgia, increased pulse pressure, compromised motor function, visual anomalies, alterations in pupillary response, and papilledema.
Bowel blockage
Nausea and vomiting (bilious or fecal) may occur with intestinal obstruction, particularly in the upper small intestine. Abdominal pain is typically intermittent and colicky, although it can escalate to a severe and constant nature. Constipation manifests early in big intestinal blockage and later in small intestinal obstruction. Obstipation may indicate total occlusion. In partial obstruction, bowel sounds are generally high-pitched and hyperactive; in complete obstruction, bowel sounds are frequently hypoactive or nonexistent. Abdominal distension and pain may present, potentially accompanied by observable peristaltic waves and a palpable abdominal mass.
Labyrinthitis
Nausea and vomiting frequently accompany this acute inner ear irritation. Additional observations encompass profound vertigo, advancing auditory impairment, nystagmus, and maybe otorrhea.
Listeriosis
Following the consumption of food contaminated with the bacterium Listeria monocytogenes, symptoms such as vomiting, fever, myalgia, stomach discomfort, nausea, and diarrhea manifest. Should the infection disseminate to the neurological system, meningitis may ensue. Symptoms may encompass fever, headache, nuchal stiffness, and alterations in level of consciousness. The foodborne sickness predominantly impacts pregnant women, infants, and individuals with compromised immune systems.
Infections during pregnancy can result in preterm delivery, neonatal infection, or stillbirth.
Thrombosis of the mesenteric veins
Nausea, vomiting, and stomach discomfort may present insidiously or acutely, accompanied by diarrhea or constipation, abdominal distension, hematemesis, and melena.
Migraine cephalalgia
Nausea and vomiting are prodromal signs and symptoms, accompanied by exhaustion, photophobia, visual disturbances, heightened sensitivity to sound, and maybe partial vision loss and paresthesia.
Cinetosis
Nausea and vomiting may occur alongside headache, vertigo, dizziness, fatigue, diaphoresis, and dyspnea.
Norovirus
Typically, 24 to 60 hours post-exposure to Norovirus, the patient suffers vomiting alongside other acute gastroenteritis symptoms, including watery non-bloody diarrhea, stomach cramps, nausea, and low-grade fever. Symptoms often persist for 1 to 5 days, and the majority of individuals recuperate without intervention. Dehydration, a more severe consequence, is commonly observed in pediatric and geriatric patients.
Acute pancreatitis
Vomiting, typically accompanied by nausea, is a first indicator of pancreatitis. Accompanying symptoms consist of persistent, intense epigastric or left upper quadrant pain that may radiate to the back, stomach discomfort and rigidity, diminished bowel sounds, loss of appetite, vomiting, and fever. In extreme cases, tachycardia, restlessness, hypotension, skin mottling, and chilly, clammy extremities may manifest.
Peritonitis
Nausea and vomiting typically accompany acute abdominal discomfort in the region of inflammation. Additional findings encompass elevated temperature accompanied by chills; tachycardia; diminished or nonexistent bowel sounds; abdominal distension, rigidity, and soreness; weakness; pallid, cool skin; diaphoresis; hypotension; indicators of dehydration; and shallow respirations.
Preeclampsia
Nausea and vomiting frequently occur with preeclampsia, a pregnancy-related condition. Rapid weight gain, epigastric discomfort, widespread edema, hypertension, oliguria, intense frontal headache, and hazy or diplopic vision may also manifest.
Q fever
The manifestations of Q fever, a rickettsial infection, including vomiting, fever, chills, intense headache, malaise, thoracic discomfort, nausea, and diarrhea. Fever may persist for a duration of up to two weeks. In extreme instances, the patient may experience hepatitis or pneumonia.
Renal and urological diseases
Cystitis, pyelonephritis, calculi, and other abnormalities of this system may induce vomiting. The accompanying findings indicate the exact condition. Chronic renal failure, whether acute or exacerbated, commonly presents with persistent nausea and vomiting.
Rhabdomyolysis
The manifestations of this illness encompass emesis, myalgia or muscular weakness, pyrexia, nausea, malaise, and darkened urine. Acute renal failure is the most often documented complication of the condition. It arises from obstruction and damage to renal structures during the kidney's effort to filter myoglobin from the bloodstream.
Typhus
Typhus is a rickettsial illness spread to people by fleas, mites, or body lice. Initial symptoms comprise headache, myalgia, arthralgia, and malaise, succeeded by a sudden onset of vomiting, nausea, chills, and fever. A maculopapular rash may occur in certain instances.
Alternative Causes Pharmaceutical substances
Medications frequently associated with emesis encompass antineoplastics, opiates, ferrous sulfate, levodopa, oral potassium, chloride substitutes, estrogens, sulfasalazine, antibiotics, quinidine, anesthetics, and overdoses of cardiac glycosides and theophylline. Radiation therapy and surgical intervention. Radiation therapy can induce nausea and vomiting if it affects the gastrointestinal mucosa. Postoperative nausea and vomiting frequently occur, particularly following abdominal surgery.
Obtain a blood sample to assess fluid, electrolyte, and acid-base equilibrium. Prolonged vomiting may result in dehydration, electrolyte abnormalities, and metabolic alkalosis. Instruct the patient to engage in deep breathing to alleviate nausea and mitigate the risk of more vomiting. Maintain a fresh and clean aroma in his room by swiftly removing bedpans and emesis basins after use. Elevate his head or position him laterally to avert aspiration of vomitus. Consistently observe vital signs and track intake and output, including emesis and liquid feces. If required, deliver intravenous fluids or allow the patient to consume clear drinks to ensure hydration. Administer pain medications promptly, as pain can trigger or exacerbate nausea and vomiting. Administer them via injection or suppository, if feasible, to decrease the risk of worsening concomitant nausea. When utilizing an opioid for pain management, meticulously monitor bowel sounds, flatus, and bowel motions, as opioids may impede gastrointestinal motility and intensify vomiting. Upon administering an antiemetic, monitor for abdominal distension and hypoactive bowel sounds, as these may signify gastric retention. In the event of this occurrence, implant a nasogastric tube.
Pyloric blockage in a neonate may result in projectile vomiting, while Hirschsprung’s disease may lead to fecal vomiting. Intussusception can result in the vomiting of bile and fecal waste in an infant or toddler. Due to an infant's underdeveloped cough and gag reflexes, he may aspirate vomitus; thus, position him on his side or abdomen and promptly remove any vomitus. Patient Guidance Instruct the patient to modify his diet by initially consuming clear liquids, followed by a progression to a bland diet. Elucidate the methods for replenishing fluid deficits and executing deep breathing exercises.
While older people may exhibit several aforementioned illnesses, it is imperative to first exclude intestinal ischemia, since it is particularly prevalent in this demographic and associated with a high fatality rate.
