Bowel sounds, hyperactive: Medical causes
(Handbook of Signs & Symptoms (Third Edition))

❑ Crohn's disease. Hyperactive bowel sounds usually arise insidiously. Associated signs and symptoms include diarrhea, cramping abdominal pain that may be relieved by defecation, anorexia, a low-grade fever, abdominal distention and tenderness and, in many cases, a fixed mass in the right lower quadrant. Perianal and vaginal lesions are common. Muscle wasting, weight loss, and signs of dehydration may occur as Crohn's disease progresses.

❑ Food hypersensitivity. Malabsorption — typically lactose intolerance — may cause hyperactive bowel sounds. Associated signs and symptoms include diarrhea and, possibly, nausea and vomiting, angioedema, and urticaria.

❑ Gastroenteritis. Hyperactive bowel sounds follow sudden nausea and vomiting and accompany “explosive” diarrhea. Abdominal cramping or pain is common, usually after a peristaltic wave. Fever may occur, depending on the causative organism.

❑ GI hemorrhage. Hyperactive bowel sounds provide the most immediate indication of persistent upper GI bleeding. Other findings include hematemesis, coffee-ground vomitus, abdominal distention, bloody diarrhea, rectal passage of bright red clots and jellylike material or melena, and pain during bleeding. Decreased urine output, tachycardia, and hypotension accompany blood loss.

❑ Mechanical intestinal obstruction. Hyperactive bowel sounds occur simultaneously with cramping abdominal pain every few minutes in patients with mechanical intestinal obstruction, a potentially life-threatening disorder; bowel sounds may later become hypoactive and then disappear. With small-bowel obstruction, nausea and vomiting occur earlier and with greater severity than in large-bowel obstruction. With complete bowel obstruction, hyperactive sounds are also accompanied by abdominal distention and constipation, although the part of the bowel distal to the obstruction may continue to empty for up to 3 days.

❑ Ulcerative colitis (acute). Hyperactive bowel sounds arise abruptly in patients with ulcerative colitis and are accompanied by bloody diarrhea, anorexia, abdominal pain, nausea and vomiting, fever, and tenesmus. Weight loss, arthralgias, and arthritis may occur.

Bowel sounds, hypoactive: Medical causes
(Handbook of Signs & Symptoms (Third Edition))

❑ Mechanical intestinal obstruction. Bowel sounds may become hypoactive after a period of hyperactivity. The patient may also have acute colicky abdominal pain in the quadrant of obstruction, possibly radiating to the flank or lumbar region; nausea and vomiting (the higher the obstruction, the earlier and more severe the vomiting); constipation; and abdominal distention and bloating. If the obstruction becomes complete, signs of shock may occur.

❑ Mesenteric artery occlusion. After a brief period of hyperactivity, bowel sounds become hypoactive and then quickly disappear, signifying a life-threatening crisis. Associated signs and symptoms include fever; a history of colicky abdominal pain leading to sudden and severe midepigastric or periumbilical pain, followed by abdominal distention and possible bruits; vomiting; constipation; and signs of shock. Abdominal rigidity may appear late.

❑ Paralytic (adynamic) ileus. Bowel sounds are hypoactive and may become absent. Associated signs and symptoms include abdominal distention, generalized discomfort, and constipation or passage of small, liquid stools and flatus. If the disorder follows acute abdominal infection, fever and abdominal pain may occur.

Other causes

❑ Drugs. Certain classes of drugs reduce intestinal motility and thus produce hypoactive bowel sounds. These include opiates, such as codeine; anticholinergics, such as propantheline bromide; phenothiazines, such as chlorpromazine; and vinca alkaloids such as vincristine. General or spinal anesthetics produce transient hypoactive sounds.

❑ Radiation therapy. Hypoactive bowel sounds and abdominal tenderness may occur after irradiation of the abdomen.

❑ Surgery. Hypoactive bowel sounds may occur after manipulation of the bowel. Motility and bowel sounds in the small intestine usually resume within 24 hours; colonic bowel sounds, in 3 to 5 days.

Vomiting: Medical causes
(Handbook of Signs & Symptoms (Third Edition))

Adrenal insufficiency

Common GI findings with the disorder include vomiting, nausea, anorexia, and diarrhea. Other findings include weakness; fatigue; weight loss; bronze skin; orthostatic hypotension; and weak, irregular pulse.

Anthrax (GI)

Initial signs and symptoms after eating contaminated meat from an infected animal include vomiting, loss of appetite, nausea, and fever. Signs and symptoms may progress to abdominal pain, severe bloody diarrhea, and hematemesis.

Appendicitis

Vomiting and nausea may follow or accompany abdominal pain. Pain typically begins as vague epigastric or periumbilical discomfort and rapidly progresses to severe, stabbing pain in the right lower quadrant. The patient generally has a positive McBurney’s sign — severe pain and tenderness on palpation about 2" (5 cm) from the right anterior superior spine of the ilium, on a line between that spine and the umbilicus. Associated findings usually include abdominal rigidity and tenderness, anorexia, constipation or diarrhea, cutaneous hyperalgesia, fever, tachycardia, and malaise.

Cholecystitis (acute)

With cholecystitis, nausea and mild vomiting commonly follow severe right-upper-quadrant pain that may radiate to the back or shoulders. Associated findings include abdominal tenderness and, possibly, rigidity and distention, fever, and diaphoresis.

Cholelithiasis

Nausea and vomiting accompany severe unlocalized right-upper-quadrant or epigastric pain after ingestion of fatty foods. Other findings include abdominal tenderness and guarding, flatulence, belching, epigastric burning, pyrosis, tachycardia, and restlessness.

Cholera

Signs and symptoms include vomiting and abrupt watery diarrhea. Severe water and electrolyte loss leads to thirst, weakness, muscle cramps, decreased skin turgor, oliguria, tachycardia, and hypotension. Without treatment, death can occur within hours.

Cirrhosis

Insidious early signs and symptoms of cirrhosis typically include nausea and vomiting, anorexia, aching abdominal pain, and constipation or diarrhea. Later findings include jaundice, hepatomegaly, and abdominal distention.

Electrolyte imbalances

Such disturbances as hyponatremia, hypernatremia, hypokalemia, and hypercalcemia frequently cause nausea and vomiting. Other effects include arrhythmias, tremors, seizures, anorexia, malaise, and weakness.

Escherichia coli (E. coli)

O157:H7. The signs and symptoms of this infection include vomiting, watery or bloody diarrhea, nausea, fever, and abdominal cramps. In children younger than age 5 and the elderly, hemolytic uremic syndrome may develop in which the red blood cells are destroyed, and this may ultimately lead to acute renal failure.

Food poisoning

Vomiting is a common finding of food poisoning, caused by preformed toxins produced by bacteria typically found in foods, such as Bacillus cereus, Clostridium, and Staphylococcus. Diarrhea and fever also usually occur.

Gastric cancer

This rare cancer may produce mild nausea, vomiting (possibly of mucus or blood), anorexia, upper abdominal discomfort, and chronic dyspepsia. Fatigue, weight loss, melena, and altered bowel habits are also common.

Gastritis

Nausea and vomiting of mucus or blood are common with gastritis, especially after ingestion of alcohol, aspirin, spicy foods, or caffeine. Epigastric pain, belching, and fever may occur.

Gastroenteritis

Gastroenteritis causes nausea, vomiting (often of undigested food), diarrhea, and abdominal cramping. Fever, malaise, hyperactive bowel sounds, and abdominal pain and tenderness may also occur.

Heart failure

Nausea and vomiting may occur, especially with right-sided heart failure. Associated findings include tachycardia, ventricular gallop, fatigue, dyspnea, crackles, peripheral edema, and jugular vein distention.

Hepatitis

Vomiting commonly follows nausea as an early sign of viral hepatitis. Other early findings include fatigue, myalgia, arthralgia, headache, photophobia, anorexia, pharyngitis, cough, and fever.

Hyperemesis gravidarum

Unremitting nausea and vomiting that last beyond the first trimester characterize this disorder of pregnancy. Vomitus contains undigested food, mucus, and small amounts of bile early in the disorder; later, it has a coffee-ground appearance. Associated findings include weight loss, headache, and delirium. Thyroid dysfunction may be associated with this condition.

Increased intracranial pressure

Projectile vomiting that isn’t preceded by nausea is a sign of increased intracranial pressure. The patient may exhibit a decreased LOC and Cushing’s triad (bradycardia, hypertension, and respiratory pattern changes). He may also have headache, widened pulse pressure, impaired motor movement, visual disturbances, pupillary changes, and papilledema.

Intestinal obstruction

Nausea and vomiting (bilious or fecal) are common with intestinal obstruction, especially of the upper small intestine. Abdominal pain is usually episodic and colicky but can become severe and steady. Constipation occurs early in large intestinal obstruction and late in small intestinal obstruction. Obstipation, however, may signal complete obstruction. In partial obstruction, bowel sounds are typically high pitched and hyperactive; in complete obstruction, bowel sounds are typically hypoactive or absent. Abdominal distention and tenderness also occur, possibly with visible peristaltic waves and a palpable abdominal mass.

Labyrinthitis

Nausea and vomiting commonly occur with this acute inner ear inflammation. Other findings include severe vertigo, progressive hearing loss, nystagmus, and possibly otorrhea.

Listeriosis

After the ingestion of food contaminated with the bacterium Listeria monocytogenes, vomiting, fever, myalgias, abdominal pain, nausea, and diarrhea occur. If the infection spreads to the nervous system, meningitis may develop. Signs and symptoms may include fever, headache, nuchal rigidity, and change in LOC. The food-borne illness primarily affects pregnant women, neonates, and those with weakened immune systems.

Gender Cue:Infections that occur during pregnancy may lead to premature delivery, infection of the neonate, or stillbirth.

Mesenteric venous thrombosis

Insidious or acute onset of nausea, vomiting, and abdominal pain occurs here, with diarrhea or constipation, abdominal distention, hematemesis, and melena.

Migraine headache

Nausea and vomiting are prodromal signs and symptoms, with fatigue, photophobia, light flashes, increased noise sensitivity, and possibly partial vision loss and paresthesia.

Motion sickness

Nausea and vomiting may be accompanied by headache, vertigo, dizziness, fatigue, diaphoresis, and dyspnea.

Pancreatitis (acute)

Vomiting, usually preceded by nausea, is an early sign of pancreatitis. Associated findings include steady, severe epigastric or left-upper-quadrant pain that may radiate to the back, abdominal tenderness and rigidity, hypoactive bowel sounds, anorexia, vomiting, and fever. Tachycardia, restlessness, hypotension, skin mottling, and cold, sweaty extremities may occur in severe cases.

Peritonitis

Nausea and vomiting usually accompany acute abdominal pain in the area of inflammation. Other findings include high fever with chills; tachycardia; hypoactive or absent bowel sounds; abdominal distention, rigidity, and tenderness; weakness; pale, cold skin; diaphoresis; hypotension; signs of dehydration; and shallow respirations.

Preeclampsia

Nausea and vomiting are common with preeclampsia, a disorder of pregnancy. Rapid weight gain, epigastric pain, generalized edema, elevated blood pressure, oliguria, severe frontal headache, and blurred or double vision also occur.

Q fever

Signs and symptoms of Q fever, a rickettsial infection, include vomiting, fever, chills, severe headache, malaise, chest pain, nausea, and diarrhea. Fever may last up to 2 weeks. In severe cases, the patient may develop hepatitis or pneumonia.

Renal and urologic disorders

Cystitis, pyelonephritis, calculi, and other disorders of this system can cause vomiting. Accompanying findings reflect the specific disorder. Persistent nausea and vomiting are typical findings in patients with acute or worsening chronic renal failure.

Rhabdomyolysis

Signs and symptoms of this disorder include vomiting, muscle weakness or pain, fever, nausea, malaise, and dark urine. Acute renal failure is the most commonly reported complication of the disorder. It results from renal structure obstruction and injury during the kidney’s attempt to filter the myoglobin from the bloodstream.

Typhus

Typhus is a rickettsial disease transmitted to humans by fleas, mites, or body louse. Initial symptoms include headache, myalgia, arthralgia, and malaise, followed by an abrupt onset of vomiting, nausea, chills, and fever. A maculopapular rash may be present in some cases.

Other causes

Drugs

Drugs that commonly cause vomiting include antineoplastics, opiates, ferrous sulfate, levodopa, oral potassium, chloride replacements, estrogens, sulfasalazine, antibiotics, quinidine, anesthetics, and overdoses of cardiac glycosides and theophylline. Syrup of ipecac is a mixture of ipecac fluid extract, glycerin, and syrup. It’s used to treat overdoses by inducing vomiting.

Radiation and surgery

Radiation therapy may cause nausea and vomiting if it disrupts the gastric mucosa. Postoperative nausea and vomiting are common, especially after abdominal surgery.

Nausea and vomiting commonly occur with labyrinthitis, an acute inner ear inflammation. Other findings include severe vertigo, progressive hearing loss, nystagmus and, possibly, otorrhea.

Listeriosis

Ménière’s disease

Ménière’s disease causes sudden, brief, recurrent attacks of nausea and vomiting, dizziness, vertigo, hearing loss, tinnitus, diaphoresis, and nystagmus.

Mesenteric artery ischemia

A life-threatening disorder, mesenteric artery ischemia may cause nausea and vomiting and severe, cramping abdominal pain, especially after meals. Other findings include diarrhea or constipation, abdominal tenderness and bloating, anorexia, weight loss, and abdominal bruits.

Mesenteric venous thrombosis

An insidious or an acute onset of nausea, vomiting, and abdominal pain occur with mesenteric venous thrombosis and may be accompanied by diarrhea or constipation, abdominal distention, hematemesis, and melena.

Metabolic acidosis

Metabolic acidosis is an imbalance that may produce nausea, vomiting, anorexia, diarrhea, Kussmaul’s respirations, and a decreased LOC.

Migraine headache

Nausea and vomiting are prodromal signs and symptoms, with fatigue, photophobia, light flashes, increased noise sensitivity and, possibly, partial vision loss and paresthesia.

Motion sickness

Nausea and vomiting may be accompanied by headache, vertigo, dizziness, fatigue, diaphoresis, and dyspnea.

Myocardial infarction

Nausea and vomiting may occur, but the cardinal symptom is severe substernal chest pain, which may radiate to the left arm, jaw, or neck. Dyspnea, pallor, clammy skin, diaphoresis, and restlessness also occur.

Pancreatitis (acute)

Vomiting, usually preceded by nausea, is an early sign of pancreatitis. Associated findings include steady, severe epigastric or left upper quadrant pain that may radiate to the back, abdominal tenderness and rigidity, hypoactive bowel sounds, anorexia, vomiting, and fever. Tachycardia, restlessness, hypotension, skin mottling, and cold, sweaty extremities may occur in severe cases.

Bowel sounds, hyperactive: Medical causes
(Signs & Symptoms: A 2-in-1 Reference for Nurses)

Crohn’s disease

Hyperactive bowel sounds usually arise insidiously in those with Crohn’s disease. Associated signs and symptoms include diarrhea, cramping abdominal pain that may be relieved by defecation, anorexia, low-grade fever, abdominal distention and tenderness and, in many cases, a fixed mass in the right lower quadrant. Muscle wasting, weight loss, and signs of dehydration may occur as Crohn’s disease progresses.

Gastroenteritis

With gastroenteritis, hyperactive bowel sounds follow sudden nausea and vomiting and accompany “explosive” diarrhea. Abdominal cramping or pain is common, typically after a peristaltic wave. Fever may occur, depending on the causative organism.

GI hemorrhage

Hyperactive bowel sounds provide the most immediate indication of persistent upper GI bleeding. Other findings include hematemesis, coffee-ground vomitus, abdominal distention, bloody diarrhea, rectal passage of bright red clots and jellylike material or melena, and pain during bleeding. Decreased urine output, tachycardia, and hypotension accompany blood loss.

Malabsorption

Malabsorption — typically lactose intolerance — may cause hyperactive bowel sounds. Associated signs and symptoms include diarrhea and, possibly, nausea and vomiting, angioedema, and urticaria.

Mechanical intestinal obstruction

Mechanical intestinal obstruction — a potentially life-threatening disorder — causes hyperactive bowel sounds to occur simultaneously with cramping abdominal pain every few minutes; bowel sounds may later become hypoactive and then disappear. With small-bowel obstruction, nausea and vomiting occur earlier and with greater severity than in large-bowel obstruction. With complete bowel obstruction, hyperactive sounds are also accompanied by abdominal distention and constipation, although the part of the bowel distal to the obstruction may continue to empty for up to 3 days.

Ulcerative colitis (acute)

Hyperactive bowel sounds arise abruptly in patients with acute ulcerative colitis. The hallmark of this disorder is recurrent bloody diarrhea (usually containing pus and mucus) accompanied by anorexia, abdominal pain, nausea and vomiting, fever, and tenesmus. Weight loss, arthralgia, and arthritis may occur.

Bowel sounds, hypoactive: Medical causes
(Signs & Symptoms: A 2-in-1 Reference for Nurses)

Mechanical intestinal obstruction

In a patient with a mechanical intestinal obstruction, bowel sounds may become hypoactive after a period of hyperactivity. The patient may also have acute colicky abdominal pain in the quadrant of obstruction, possibly radiating to the flank or lumbar region; nausea and vomiting (the higher the obstruction, the earlier and more severe the vomiting); constipation; and abdominal distention and bloating. If the obstruction becomes complete, signs of shock may occur.

Mesenteric artery occlusion

In cases of mesenteric artery occlusion, bowel sounds become hypoactive after a brief period of hyperactivity and then quickly disappear, signifying a life-threatening crisis. Associated signs and symptoms include fever; a history of colicky abdominal pain leading to sudden and severe midepigastric or periumbilical pain, followed by abdominal distention and possible bruits; vomiting; constipation; and signs of shock. Abdominal rigidity may appear late.

Paralytic ileus

With paralytic (adynamic) ileus, bowel sounds are hypoactive and may become absent. Associated signs and symptoms include abdominal distention, generalized discomfort, and constipation or passage of small, liquid stools and flatus. If the disorder follows acute abdominal infection, fever and abdominal pain may occur.

Other causes

Drugs

Certain classes of drugs reduce intestinal motility and thus produce hypoactive bowel sounds. These include opiates such as codeine, anticholinergics such as propantheline, phenothiazines such as chlorpromazine, and vinca alkaloids such as vincristine. General or spinal anesthetics produce transient hypoactive sounds.

Surgery

Hypoactive bowel sounds may occur after surgical manipulation of the bowel. Motility and bowel sounds in the small intestine usually resume within 24 hours; colonic bowel sounds, in 3 to 5 days.

Vomiting: Medical causes
(Signs & Symptoms: A 2-in-1 Reference for Nurses)

Adrenal insufficiency

Common GI findings associated with adrenal insufficiency include vomiting, nausea, anorexia, and diarrhea. Other findings include weakness; fatigue; weight loss; bronze skin; orthostatic hypotension; and weak, irregular pulse.

Anthrax (GI)

With anthrax, initial signs and symptoms after eating contaminated meat from an infected animal include vomiting, loss of appetite, nausea, and fever. Signs and symptoms may progress to abdominal pain, severe bloody diarrhea, and hematemesis.

Appendicitis

With appendicitis, vomiting and nausea may follow or accompany abdominal pain. Pain typically begins as vague epigastric or periumbilical discomfort and rapidly progresses to severe, stabbing pain in the right lower quadrant. The patient generally has a positive McBurney’s sign — severe pain and tenderness on palpation about 2"(5 cm) from the right anterior superior spine of the ilium, on a line between that spine and the umbilicus. Associated findings usually include abdominal rigidity and tenderness, anorexia, constipation or diarrhea, cutaneous hyperalgesia, fever, tachycardia, and malaise.

Bulimia

Most common in women ages 18 to 29, bulimia is characterized by polyphagia that alternates with self-induced vomiting, fasting, or diarrhea. It’s commonly accompanied by anorexia. The patient typically weighs less than normal but has a morbid fear of obesity. Self-induced vomiting may be evidenced by calloused knuckles.

Cholecystitis (acute)

With acute cholecystitis, nausea and mild vomiting commonly follow severe right-upper-quadrant pain that may radiate to the back or shoulders. Associated findings include abdominal tenderness and, possibly, rigidity and distention, fever, and diaphoresis.

Cholelithiasis

Nausea and vomiting accompany severe unlocalized right-upper-quadrant or epigastric pain after ingestion of fatty foods. Other findings in cholelithiasis include abdominal tenderness and guarding, flatulence, belching, epigastric burning, pyrosis, tachycardia, and restlessness.

Cirrhosis

Insidious early signs and symptoms of cirrhosis typically include nausea and vomiting, anorexia, aching abdominal pain, and constipation or diarrhea. Later findings include jaundice, hepatomegaly, and abdominal distention.

Escherichia coli 0157:H7

The signs and symptoms of E. coli include vomiting, watery or bloody diarrhea, nausea, fever, and abdominal cramps. In children younger than age 5 and elderly patients, hemolytic uremic syndrome may develop in which the red blood cells are destroyed, and this may ultimately lead to acute renal failure.

Ectopic pregnancy

Vomiting, nausea, vaginal bleeding, and lower abdominal pain occur in ectopic pregnancy, a potentially life-threatening disorder. The patient with an ectopic pregnancy may have a tender adrenal mass and a 1- to -2-month history of amenorrhea.

Electrolyte imbalances

Electrolyte imbalances such as hyponatremia, hypernatremia, hypokalemia, and hypercalcemia frequently cause nausea and vomiting. Other effects include arrhythmias, tremors, seizures, anorexia, malaise, and weakness.

Food poisoning

Vomiting is a common finding in food poisoning. Diarrhea, severe, cramping abdominal pain, prostration, and fever also usually occur.

Gastritis

Nausea and vomiting of mucus or blood are common with gastritis, especially after ingestion of alcohol, aspirin, spicy foods, or caffeine. Epigastric pain, belching, and fever may occur.

Gastroenteritis

Gastroenteritis causes nausea, vomiting (often of undigested food), diarrhea, and abdominal cramping. Fever, malaise, hyperactive bowel sounds, and abdominal pain and tenderness may also occur.

Heart failure

Nausea and vomiting may occur, especially with right-sided heart failure. Associated findings include tachycardia, ventricular gallop, fatigue, dyspnea, crackles, peripheral edema, and jugular vein distention.

Hepatitis

Vomiting commonly follows nausea as an early sign of viral hepatitis. Other early findings include fatigue, myalgia, arthralgia, headache, photophobia, anorexia, pharyngitis, cough, and fever.

Hyperemesis gravidarum

Unremitting nausea and vomiting that last beyond the first trimester characterize hyperemesis gravidarum, a disorder of pregnancy. Vomitus contains undigested food, mucus, and small amounts of bile early in the disorder; later, it has a coffee-ground appearance. Associated findings include weight loss, headache, and delirium.

Increased intracranial pressure

Projectile vomiting that isn’t preceded by nausea is a sign of increased ICP. The patient may exhibit a decreased level of consciousness (LOC) and Cushing’s triad (bradycardia, hypertension, and respiratory pattern changes). He may also have headache, widened pulse pressure, impaired motor movement, vision disturbances, pupillary changes, and papilledema.

Intestinal obstruction

Nausea and vomiting (bilious or fecal) are common with intestinal obstruction, especially of the upper small intestine. Abdominal pain is usually episodic and colicky but can become severe and steady. Constipation occurs early in large intestinal obstruction and late in small intestinal obstruction. Obstipation, however, may signal complete obstruction. In partial obstruction bowel sounds are typically high pitched and hyperactive; in complete obstruction, hypoactive or absent. Abdominal distention and tenderness also occur, possibly with visible peristaltic waves and a palpable abdominal mass.

Labyrinthitis

Nausea and vomiting commonly occur with labyrinthitis, an acute inner ear inflammation. Other findings in labyrinthitis include severe vertigo, progressive hearing loss, nystagmus, and possibly otorrhea.

Ménière’s disease

Ménière’s disease causes sudden, brief, recurrent attacks of nausea and vomiting, dizziness, vertigo, hearing loss, tinnitus, diaphoresis, and nystagmus. Hearing loss may be progressive and tinnitus may persist between attacks.

Mesenteric artery ischemia

Mesenteric artery ischemia is a life-threatening disorder that may cause nausea and vomiting and severe, cramping abdominal pain, especially after meals. Other findings include diarrhea or constipation, abdominal tenderness and bloating, anorexia, weight loss, and abdominal bruits.

Mesenteric venous thrombosis

With mesenteric venous thrombosis, insidious or acute onset of nausea, vomiting, and abdominal pain occurs along with diarrhea or constipation, abdominal distention, hematemesis, and melena.
