Differences between Diarrhea and Dysentery


However, both the terms and these clinical conditions have clear differences as follows:

S.N.

Character

Diarrhea

Dysentery

1.      DefinitionDiarrhea refers to a condition that involves the frequent passing of loose or watery stools (atleast 3 times a day).Dysentery is an intestinal inflammation, especially in the colon, that can lead to severe diarrhea with mucus or blood in the feces.
2.      Stool typeWatery stool with no blood and mucus.Mucoid stool that may be accompanied by blood.
3.      Affects The small bowel.Affects the colon.
4.      Target cellsDiarrheal infection targets only intestinal lumen and upper epithelial cells.Dysentery not only targets upper epithelial cells but colon ulceration also results.
5.      Cell deathThere is no cell death in diarrhea and the infection is only caused due to the release of toxins by an infecting agent.When a person gets dysentery, the upper epithelial cells are attacked and destroyed by the pathogen or disease causing agent.
6.      Type of Infectious Agent Involved

 

Diarrhea is mostly viral. Dysentery is mostly bacterial. 
7.      Causative agentsNorovirus, Rotavirus, Sapovirus, Escherichia coli (E.coli), Giardia lamblia etc.Shigella, especially S. flexneri and S. dysenteriae type I, Campylobacter jejuni, especially in infants, and, less frequently, Salmonella, Enteroinvasive Escherichia coli are closely related to Shigella and may cause severe dysentery. Entamoeba histolytica cause dysentery in older children and adults, but rarely in children less than 5 years of age.
8.      Suggestive ofMay be a condition in itself or a symptom of another condition.Dysentery is a condition in itself.
9.      Major Causes·       A viral infection

·       Alcohol abuse

·       Allergies to certain foods

·       Diabetes

·       Diseases of the intestines

·       Eating foods that upset the digestive system

·       Infection by bacteria or other organisms

·       Laxative abuse

·       Medications

·       Overactive thyroid (hyperthyroidism)

·       Radiation therapy

·       Running

·       Some cancers

·       Surgery on the digestive system

·       Trouble absorbing certain nutrients, also called “malabsorption”

·       Bacterial infection

·       Viral infection

·       Parasitic worms

·       Protozoa

10.   SymptomsWatery motions, weakness, dehydration, abdominal pain and cramping (may or may not).Motion with blood and mucous, abdominal pain, weakness, cramping, vomiting, dehydration.
11.   Cramps and PainThe symptoms may or may not be accompanied by cramps or pain.The patient usually complains of cramps and pain in the lower abdominal area.
12.   FeverFever is less common in diarrhea.Fever is more common in dysentery.
13.   EffectsThe effects of diarrhea are not that serious, apart from the risk of dehydration.Dysentery can cause a lot of complications, if left untreated.
14.   Severe Symptoms·       Weight loss

·       Fever

·       Nausea

·       Severe pain in the abdomen or rectum

·       Diarrhea after coming back from a foreign country

·       Dark urine

·       Smaller than usual amounts of urine or fewer wet diapers than usual in a child

·       Rapid heart rate

·       Headaches

·       Dry skin

·       Irritability

·       Confusion

·       Feeling weak

·       Nausea

·       Weightloss

·       Delirium

·       Convulsions

·       Coma

15.   Effect on Nutritional StatusLess harmfulMore harmful effect on nutritional status than acute watery diarrhea.
16.   Morbidity/ MortalityNo significant mortality or morbidity is associated with diarrhea alone. However, deaths result from excessive dehydration.Dysentery is an important cause of morbidity and mortality associated with diarrhea. About 15% of all diarrheal episodes in children under 5 years are dysenteric, but these cause up to 25% of all diarrheal deaths.
17.   TreatmentHome Remedies

Over the Counter medicine

Oral rehydration solution (ORS)

Antibiotics

Home Remedies if mild

Over the Counter medicine if mild

Oral rehydration solution (ORS)

Antibiotics

Amoebicidal drugs

18.   Antibiotic TreatmentDiarrhea does not need antibiotics. Oral rehydration solutions or intravenous fluid therapy may be used.Dysentery almost always requires antibiotic treatment. Intravenous antibiotics may be needed in severely ill children.
19.   Effectiveness of TreatmentThe antimicrobial that are used to treat diarrhea do not eradicate the toxin left behind.Treatment for dysentery can eradicate the pathogen that is causing the infection and stop the inflammation.
20.   In absence of treatmentIf not treated, ultimately the patient recovers within 2 or 3 days as the immune system work against the infection.Could be fatal.
21.   Measures to takeProper rehydration solutions, taking liquid diet, avoiding high- risk foods, unpasteurized milk, most importantly drinking clean and pure water. Antibiotics are given along with intravenous fluid, proper care and rest is required.
