DIARRHEA IN ADULTS - INFECTIOUS

Prevention

  • General measures to prevent diarrheal diseases may include the following:
    • Washing of hands with soap
    • Drinking clean and safe water
    • Proper human waste and garbage disposal
    • Safe food processing and handling

Traveler’s Diarrhea

  • Traveler should avoid:
    • Undercooked food except peeled fruits or vegetables
    • Non-bottled beverages and unpasteurized dairy products

Water Purification

  • Travelers who are going to be living in rustic circumstances overseas will need to make arrangements for a safe water supply

Prophylactic Antibiotics 

  • Effective but cannot be recommended unless the complications of diarrhea in a traveler or severe dehydration in a person with an underlying medical condition
  • cause the benefits of antibiotic prophylaxis to outweigh the risks

Bismuth Preparations

  • May have protective efficacy over a 7-day period

Probiotics

  • May decrease the incidence of diarrhea in travelers
  • May have some value in the prevention of antibiotic-associated diarrhea

Cholera

  • V cholerae is spread through contaminated food and water
  • Prevention depends on interruption of fecal-oral transmission
  • Travelers to regions with cholera should follow precautions for the prevention of traveler’s diarrhea
  • Water can be treated with chlorine or iodine, by filtration, or by boiling 

Consultation or hospitalization is considered in the following cases:

  • Bloody stools
  • Frequent and large-volume diarrhea
  • Persistent fever and vomiting
  • Severe dehydration
  • Altered consciousness
  • Absence of improvement within 48 hours
  • No urine output in preceding 12 hours

During pregnancy, there is generalized relaxation of smooth muscle resulting in relaxa¬tion of the oesophageal sphincter, reduced gastric peristalsis, and delayed gastric emp¬tying. Small and large bowel transit times are increased. There is increased blood flow to the liver and increased production of fibrinogen, transferrin and many other binding proteins. Reference ranges for many liver function tests are altered. Gestation-specific alkaline phosphatase is increased, mainly from increased placental production, and aminotransferases and γ-glutamyltransferase are reduced.
