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

Anthrax, GI

Anthrax manifests after the patient has eaten contaminated meat from an animal infected withBacillus anthracis. Early signs and symptoms include decreased appetite, nausea, vomiting, and a fever. Later signs and symptoms include severe bloody diarrhea, abdominal pain, and hematemesis.

Carcinoid syndrome

With carcinoid syndrome, severe diarrhea occurs with flushing — usually of the head and
neck — that's commonly caused by emotional stimuli or the ingestion of food, hot water, or alcohol. Associated signs and symptoms include abdominal cramps, dyspnea, weight loss, anorexia, weakness, palpitations, valvular heart disease, and depression.

Cholera

After ingesting water or food contaminated by the bacteriumVibrio cholerae,the patient experiences abrupt watery diarrhea and vomiting. Other signs and symptoms include thirst (due to severe water and electrolyte loss), weakness, muscle cramps, decreased skin turgor, oliguria, tachycardia, and hypotension. Without treatment, death can occur within hours.

Clostridium difficile infection

The patient may be asymptomatic or may have soft, unformed stools or watery diarrhea that may be foul smelling or grossly bloody; abdominal pain, cramping, and tenderness; a fever; and a white blood cell count as high as 20,000/ml. In severe cases, the patient may develop toxic megacolon, colon perforation, or peritonitis.

Crohn's disease

Crohn's disease is a recurring inflammatory disorder that produces diarrhea accompanied by abdominal pain with guarding and tenderness and nausea. The patient may also display a fever, chills, weakness, anorexia, and weight loss.

Escherichia coli

Watery or bloody diarrhea, nausea, vomiting, fever, and abdominal cramps occur after the patient eats undercooked beef or other foods contaminated with this particular strain of bacteria. Hemolytic uremic syndrome, which causes red blood cell destruction and eventually acute renal failure, is a complication ofE. coli0157:H7 in children age 5 and younger and elderly people.

Infections

Acute viral, bacterial, and protozoal infections (such as cryptosporidiosis) cause the sudden onset of watery diarrhea as well as abdominal pain, cramps, nausea, vomiting, and a fever. Significant fluid and electrolyte loss may cause signs of dehydration and shock. Chronic tuberculosis and fungal and parasitic infections may produce a less severe but more persistent diarrhea, accompanied by epigastric distress, vomiting, weight loss and, possibly, passage of blood and mucus.

Intestinal obstruction

Partial intestinal obstruction increases intestinal motility, resulting in diarrhea, abdominal pain with tenderness and guarding, nausea and, possibly, distention.

Irritable bowel syndrome

Diarrhea alternates with constipation or normal bowel function. Related findings include abdominal pain, tenderness, and distention; dyspepsia; and nausea.

Ischemic bowel disease

Ischemic bowel disease is a life-threatening disorder that causes bloody diarrhea with abdominal pain. If severe, shock may occur, requiring surgery.

Lactose intolerance

Diarrhea occurs within several hours of ingesting milk or milk products. It's accompanied by cramps, abdominal pain, borborygmi, bloating, nausea, and flatus.

Listeriosis

With listeriosis, diarrhea occurs in conjunction with a fever, myalgia, abdominal pain, nausea, and vomiting. A fever, a headache, nuchal rigidity, and an altered level of consciousness may occur if the infection spreads to the nervous system and causes meningitis. This infection, caused by the ingestion of food contaminated with the bacteriumListeria monocytogenes primarily affects pregnant women, neonates, and those with weakened immune systems. Listeria infections during pregnancy may lead to premature delivery, infection of the neonate, or stillbirth.

Pseudomembranous enterocolitis

Pseudomembranous enterocolitis is a potentially life-threatening disorder that commonly follows antibiotic administration. It produces copious watery, green, foul-smelling, bloody diarrhea that rapidly precipitates signs of shock. Other signs and symptoms include colicky abdominal pain, distention, a fever, and dehydration.

Q Fever

Q Fever is caused by the bacterium Coxiella burnetiiand causes diarrhea along with a fever, chills, a severe headache, malaise, chest pain, and vomiting. In severe cases, hepatitis or pneumonia may follow.

Rotavirus gastroenteritis

Rotavirus gastroenteritis commonly starts with a fever, nausea, and vomiting, followed by diarrhea. The illness can range from mild to severe and can last from 3 to 9 days. Diarrhea and vomiting may result in dehydration.

Thyrotoxicosis

With thyrotoxicosis, nervousness, tremors, diaphoresis, weight loss despite increased appetite, dyspnea, palpitations, tachycardia, an enlarged thyroid, heat intolerance and, possibly, exophthalmos accompany diarrhea.

Ulcerative colitis

The hallmark of ulcerative colitis is recurrent bloody diarrhea with pus or mucus. Other signs and symptoms include tenesmus, hyperactive bowel sounds, cramping lower abdominal pain, a low-grade fever, anorexia and, at times, nausea and vomiting. Weight loss, anemia, and weakness are late findings.

Other causes

Herb alert  

Herbal reme-
dies — such as ginkgo biloba, ginseng, and licorice — may cause diarrhea.

Drugs

Many antibiotics — such as ampicillin, cephalosporins, tetracyclines, and clindamycin — cause diarrhea. Other drugs that may cause diarrhea include magnesium-containing antacids, colchicine, guanethidine, lactulose, dantrolene, ethacrynic acid, mefenamic acid, methotrexate, metyrosine and, in high doses, cardiac glycosides and quinidine. Laxative abuse can cause acute or chronic diarrhea.

Treatments

Gastrectomy, gastroenterostomy, and pyloroplasty may produce diarrhea. High-dose radiation therapy may produce enteritis associated with diarrhea.

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

Dementia

Any chronic degenerative brain disease can produce fecal as well as urinary incontinence. Associated signs and symptoms include impaired judgment and abstract thinking, amnesia, emotional lability, hyperactive deep tendon reflexes, aphasia or dysarthria and, possibly, diffuse choreoathetoid movements.

Head trauma

Disruption of the neurologic pathways that control defecation can cause fecal incontinence. Additional findings depend on the location and severity of the injury and may include a decreased level of consciousness, seizures, vomiting, and a wide range of motor and sensory impairments.

Inflammatory bowel disease

Nocturnal fecal incontinence occurs occasionally with diarrhea. Related findings include abdominal pain, anorexia, weight loss, blood in the stools, and hyperactive bowel sounds.

Rectovaginal fistula

Fecal incontinence occurs in tandem with uninhibited passage of flatus.

Spinal cord lesions

Any lesion that causes compression or transsection of sensorimotor spinal tracts can lead to fecal incontinence. Incontinence may be permanent, especially with severe lesions of the sacral segments. Other signs and symptoms reflect motor and sensory disturbances below the level of the lesion, such as urinary incontinence, weakness or paralysis, paresthesia, analgesia, and thermanesthesia.

Other causes

Drugs

Chronic laxative abuse may cause insensitivity to a fecal mass or loss of the colonic defecation reflex

Surgery

Pelvic, prostate, or rectal surgery occasionally produces temporary fecal incontinence. Colostomy or ileostomy causes permanent or temporary fecal incontinence

Fecal incontinence: Medical causes
(Professional Guide to Signs & Symptoms (Fifth Edition))

Dementia

Any chronic degenerative brain disease can produce fecal as well as urinary incontinence. Associated signs and symptoms include impaired judgment and abstract thinking, amnesia, emotional lability, hyperactive deep tendon reflexes (DTRs), aphasia or dysarthria and, possibly, diffuse choreoathetoid movements.

Gastroenteritis

Severe gastroenteritis may result in temporary fecal incontinence manifested by explosive diarrhea. Nausea, vomiting, and colicky, peristaltic abdominal pain are typical. Other findings include headache, myalgia, and hyperactive bowel sounds.

Head trauma

Disruption of the neurologic pathways that control defecation can cause fecal incontinence. Additional findings depend on the location and severity of the injury and may include decreased level of consciousness, seizures, vomiting, and a wide range of motor and sensory impairments.

Inflammatory bowel disease

Nocturnal fecal incontinence occurs occasionally with diarrhea. Related findings include abdominal pain, anorexia, weight loss, blood in the stool, and hyperactive bowel sounds.

Multiple sclerosis

Fecal incontinence occasionally appears as one of this disorder’s extremely variable signs. Other effects depend on the area of demyelination and may include muscle weakness, ataxia, and paralysis; gait disturbances; sensory impairment, such as paresthesia and genital anesthesia; visual blurring, diplopia, or nystagmus; urinary disturbances; and emotional lability.

Rectovaginal fistula

Fecal incontinence occurs in tandem with uninhibited passage of flatus.

Spinal cord lesion

Any lesion that causes compression or transsection of sensorimotor spinal tracts can lead to fecal incontinence. Incontinence may be permanent, especially with severe lesions of the sacral segments. Other signs and symptoms reflect motor and sensory disturbances below the level of the lesion, such as urinary incontinence, weakness or paralysis, paresthesia, analgesia, and thermanesthesia.

Stroke

Temporary fecal incontinence occasionally occurs in a stroke patient but usually disappears when muscle tone and DTRs are restored. Persistent fecal incontinence may reflect extensive neurologic damage. Other findings depend on the location and extent of damage and may include urinary incontinence, hemiplegia, dysarthria, aphasia, sensory losses, reflex changes, and visual field deficits. Typical generalized signs and symptoms include headache, vomiting, nuchal rigidity, fever, disorientation, mental impairment, seizures, and coma.

Tabes dorsalis

This late sign of syphilis occasionally results in fecal incontinence. It also produces urinary incontinence, ataxic gait, paresthesia, loss of DTRs and temperature sensation, severe flashing pain, Charcot’s joints, Argyll Robertson pupils, and possibly impotence.

Other causes

Drugs

Chronic laxative abuse may cause insensitivity to a fecal mass or loss of the colonic defecation reflex.

Surgery

Pelvic, prostate, or rectal surgery occasionally produces temporary fecal incontinence. A colostomy or an ileostomy causes permanent or temporary fecal incontinence.

Other drugs that may cause diarrhea include magnesium-containing antacids, colchicine, guanethidine, lactulose, dantrolene, ethacrynic acid, mefenamic acid, methotrexate, metyrosine and, in high doses, cardiac glycosides and quinidine. Laxative abuse can cause acute or chronic diarrhea.

Foods

Foods that contain certain oils may inhibit absorption of food causing acute uncontrollable diarrhea and rectal leakage.

Herbal remedies

Certain herbal remedies, such as ginkgo biloba, ginseng, and licorice, may cause diarrhea.

Medical treatments

Gastrectomy, gastroenterostomy, and pyloroplasty may produce diarrhea. High-dose radiation therapy may produce enteritis associated with diarrhea.

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

Anthrax, GI

Early signs and symptoms of GI anthrax, an infectious disease caused by eating meat contaminated with the bacterium Bacillus anthracis, include decreased appetite, nausea, vomiting, and fever. Later signs and symptoms include severe bloody diarrhea, abdominal pain, and hematemesis.

Clostridium difficile infection

With a Clostridium difficile infection, the patient may be asymptomatic or may have soft, unformed stools or watery diarrhea that may be foul smelling or grossly bloody; abdominal pain, cramping, and tenderness; fever; and a white blood cell count as high as 20,000/µl. In severe cases, the patient may develop toxic megacolon, colonic perforation, or peritonitis.

Crohn’s disease

Crohn’s disease, a recurring inflammatory disorder, produces diarrhea accompanied by abdominal pain with guarding and tenderness, and nausea. The patient may also display fever, chills, weakness, anorexia, and weight loss.

Escherichia coli 0157:H7

Watery or bloody diarrhea, nausea, vomiting, fever, and abdominal cramps occur after the patient eats undercooked beef or other foods contaminated with the Escherichia coli 0157:H7 strain of bacteria. Hemolytic uremic syndrome, which causes red blood cell destruction and eventually acute renal failure, is a complication of   E. coli 0157:H7 in children age 5 and younger and elderly people.

Infections

Acute viral, bacterial, and protozoal infections (such as cryptosporidiosis) cause the sudden onset of watery diarrhea as well as abdominal pain, cramps, nausea, vomiting, and fever. Significant fluid and electrolyte loss may cause signs of dehydration and shock. Chronic tuberculosis and fungal and parasitic infections may produce a less severe but more persistent diarrhea, accompanied by epigastric distress, vomiting, weight loss and, possibly, passage of blood and mucus.

Intestinal obstruction

Partial intestinal obstruction increases intestinal motility, resulting in diarrhea, abdominal pain with tenderness and guarding, nausea and, possibly, distention. Other signs and symptoms may include borborygmi and rushes on auscultation and vomiting of fecal material.

Irritable bowel syndrome

Diarrhea alternates with constipation or normal bowel function. Related findings include abdominal pain, tenderness, and distention; dyspepsia; and nausea. The patient may also report passage of mucus and pasty pencil-like stools.

Ischemic bowel disease

A life-threatening disorder, ischemic bowel disease causes bloody diarrhea with abdominal pain. The patient may also experience abdominal distention, nausea, and vomiting. If severe, shock may occur, requiring surgery.

Lactose intolerance

Diarrhea occurs within several hours of ingesting milk or milk products. It’s accompanied by cramps, abdominal pain, borborygmi, bloating, nausea, and flatus.

Large-bowel cancer

With large-bowel cancer, bloody diarrhea is seen with a partial obstruction. Other signs and symptoms include abdominal pain, anorexia, weight loss, weakness, fatigue, exertional dyspnea, and depression.

Lead poisoning

Alternating diarrhea and constipation occur in a patient with lead poisoning. Other GI effects include abdominal pain, anorexia, nausea, and vomiting. The patient complains of a metallic taste, headache, and dizziness and displays a bluish gingival lead line.

Malabsorption syndrome

In a patient with malabsorption syndrome, diarrhea occurs after meals, accompanied by steatorrhea, abdominal distention, and muscle cramps. The patient also displays anorexia, weight loss, bone pain, anemia, weakness, and fatigue. He may bruise easily and have night blindness.

Pseudomembranous enterocolitis

Pseudomembranous enterocolitis, a potentially life-threatening disorder, commonly follows antibiotic administration. It produces copious watery, green, foul-smelling, bloody diarrhea that rapidly precipitates signs of shock. Other signs and symptoms include colicky abdominal pain, distention, fever, and dehydration.

Q Fever

Q Fever is an infection that’s caused by the bacterium Coxiella burnetii and causes diarrhea along with fever, chills, severe headache, malaise, chest pain, and vomiting. In severe cases, hepatitis or pneumonia may follow. Chronic Q fever may cause prolonged fever, night sweats, chills, fatigue, and dyspnea.

Rotavirus gastroenteritis

Rotavirus gastroenteritis commonly starts with a fever, nausea, and vomiting, followed by diarrhea. The illness can range from mild to severe and last from 3 to 9 days. Diarrhea and vomiting may result in dehydration.

Thyrotoxicosis

With thyrotoxicosis, diarrhea is accompanied by nervousness, tremors, diaphoresis, weight loss despite increased appetite, dyspnea, palpitations, tachycardia, enlarged thyroid, heat intolerance and, possibly, exophthalmos.

Ulcerative colitis

The hallmark of ulcerative colitis is recurrent bloody diarrhea with pus or mucus. Other signs and symptoms include tenesmus, hyperactive bowel sounds, cramping lower abdominal pain, low-grade fever, anorexia and, at times, nausea and vomiting. Weight loss, anemia, and weakness are late findings.

Other causes

Drugs

Many antibiotics — such as ampicillin, cephalosporins, tetracyclines, and clindamycin — cause diarrhea. Other drugs that may cause diarrhea include magnesium-containing antacids, colchicine, guanethidine, lactulose, dantrolene, ethacrynic acid, mefenamic acid, methotrexate, metyrosine and, in high doses, cardiac glycosides and quinidine. Laxative abuse can cause acute or chronic diarrhea. Herbal remedies — such as ginkgo biloba, ginseng, and licorice — may also cause diarrhea.

Foods

Foods that contain certain oils may inhibit absorption causing acute uncontrollable diarrhea and rectal leakage.

Treatments

Gastrectomy, gastroenterostomy, and pyloroplasty may produce diarrhea. High-dose radiation therapy may produce enteritis, which is associated with diarrhea.

Diarrhea: Medical causes
(Nursing: Interpreting Signs and Symptoms)

Anthrax (GI).Anthrax manifests after the patient has eaten contaminated meat from an animal infected with Bacillus anthracis. Early signs and symptoms include decreased appetite, nausea, vomiting, and a fever. Later signs and symptoms include severe bloody diarrhea, abdominal pain, and hematemesis.

Carcinoid syndrome.With carcinoid syndrome, severe diarrhea occurs with flushing—usually of the head and neck—that's commonly caused by emotional stimuli or the ingestion of food, hot water, or alcohol. Associated signs and symptoms include abdominal cramps, dyspnea, weight loss, anorexia, weakness, palpitations, valvular heart disease, and depression.

Cholera.After ingesting water or food contaminated by the bacterium Vibrio cholerae, the patient experiences abrupt watery diarrhea and vomiting. Other signs and symptoms include thirst (due to severe water and electrolyte loss), weakness, muscle cramps, decreased skin turgor, oliguria, tachycardia, and hypotension. Without treatment, death can occur within hours.

Clostridium difficile infection. The patient may be asymptomatic or may have soft, unformed stools or watery diarrhea that may be foul smelling or grossly bloody; abdominal pain, cramping, and tenderness; a fever; and a white blood cell count as high as 20,000/ml. In severe cases, the patient may develop toxic megacolon, colon perforation, or peritonitis.

Crohn's disease.Crohn's disease is a recurring inflammatory disorder that produces diarrhea accompanied by abdominal pain with guarding and tenderness and nausea. The patient may also display a fever, chills, weakness, anorexia, and weight loss.

Escherichia coli O157:H7. Watery or bloody diarrhea, nausea, vomiting, fever, and abdominal cramps occur after the patient eats undercooked beef or other foods contaminated with this particular strain of bacteria. Hemolytic uremic syndrome, which causes red blood cell destruction and eventually acute renal failure, is a complication of E. coli O157:H7 in children age 5 and younger and elderly people.

Infections.Acute viral, bacterial, and protozoal infections (such as cryptosporidiosis) cause the sudden onset of watery diarrhea as well as abdominal pain, cramps, nausea, vomiting, and a fever.

Listeriosis.With listeriosis, diarrhea occurs in conjunction with a fever, myalgia, abdominal pain, nausea, and vomiting. A fever, a headache, nuchal rigidity, and an altered level of consciousness may occur if the infection spreads to the nervous system and causes meningitis.

Pseudomembranous enterocolitis.Pseudomembranous enterocolitis is a potentially life-threatening disorder that commonly follows antibiotic administration. It produces copious watery, green, foul-smelling, bloody diarrhea that rapidly precipitates signs of shock. Other signs and symptoms include colicky abdominal pain, distention, a fever, and dehydration.

Fecal incontinence: Medical causes
(Nursing: Interpreting Signs and Symptoms)

Dementia.Any chronic degenerative brain disease can produce fecal as well as urinary incontinence. Associated signs and symptoms include impaired judgment and abstract thinking, amnesia, emotional lability, hyperactive deep tendon reflexes, aphasia or dysarthria and, possibly, diffuse choreoathetoid movements.

Head trauma.Disruption of the neurologic pathways that control defecation can cause fecal incontinence. Additional findings depend on the location and severity of the injury and may include a decreased level of consciousness, seizures, vomiting, and a wide range of motor and sensory impairments.

Inflammatory bowel disease.Nocturnal fecal incontinence occurs occasionally with diarrhea in inflammatory bowel disease. Related findings include abdominal pain, anorexia, weight loss, blood in the stools, and hyperactive bowel sounds.

Rectovaginal fistula.With a rectovaginal fistula, fecal incontinence occurs in tandem with uninhibited passage of flatus.

Spinal cord lesions.Any lesion that causes compression or transsection of sensorimotor spinal tracts can lead to fecal incontinence. Incontinence may be permanent, especially with severe lesions of the sacral segments. Other signs and symptoms reflect motor and sensory disturbances below the level of the lesion, such as urinary incontinence, weakness or paralysis, paresthesia, analgesia, and thermanesthesia.

Other causes

Drugs.Chronic laxative abuse may cause insensitivity to a fecal mass or loss of the colonic defecation reflex.

Surgery.Pelvic, prostate, or rectal surgery occasionally produces temporary fecal incontinence. Colostomy or ileostomy causes permanent or temporary fecal incontinence.

Chronic Diarrhea: Chronic Diarrhea - pathophysiology
(The 5-Minute Pediatric Consult)

The major categories are osmotic and secretory. Inflammatory and motility disorders are smaller but important subcategories to consider.

• Osmotic diarrhea occurs when unabsorbable solute accumulates in the lumen of the small intestine and colon:
  • This increases the intraluminal osmotic pressure and results in excessive fluid and electrolyte losses in stool.
  • Osmotic diarrhea will improve with fasting.
  • Osmotic diarrhea is usually related to malabsorption of dietary products or to the presence of congenital or acquired disaccharidase deficiency or glucose-galactose defects.
• Secretory diarrhea occurs when the net secretion of fluid and electrolyte is in excess of absorption in the intestine:
  • The intestinal mucosa is normally very active in both of these processes.
  • The diarrhea occurs independently of the osmotic load in the intestinal lumen and does not improve with fasting.
  • The mechanisms for secretory diarrhea include the activation of intracellular mediators such as cAMP, cGMP, and calcium-dependent channels.
  • These mediators stimulate active chloride secretion from the crypt cells and inhibit the neutral coupled sodium chloride absorption.
• Inflammation in the intestine can cause an alteration in mucosal integrity resulting in exudative loss of mucus, blood, and/or protein. Increased permeability and altered mucosal surface area may affect absorption and result in diarrhea owing to a malabsorptive process.
• Motility disorders will affect the intestinal transit time. Hypomotility states such as stasis from bacterial overgrowth can lead to diarrhea.
