From the Guidelines

Diarrhea among homeless individuals should be treated promptly with oral loperamide as the first line of treatment, given its effectiveness in relieving symptoms and safety in otherwise healthy adults. According to the guidelines for adults on self-medication for the treatment of acute diarrhoea 1, oral loperamide is the treatment of choice for acute uncomplicated diarrhoea. The study published in the Alimentary Pharmacology and Therapeutics journal in 2001 found that self-medication in otherwise healthy adults is safe and that oral loperamide is effective in relieving symptoms without prolonging the illness.

When considering the treatment of diarrhea among homeless individuals, it is essential to prioritize their unique circumstances, including limited access to sanitation and healthcare. Key considerations include:

  • The importance of maintaining fluid intake to prevent dehydration
  • The need for prompt medical intervention if symptoms persist or worsen, such as dehydration, abdominal distension, or the onset of dysentery
  • The role of oral rehydration solutions in preventing dehydration, although they may not relieve diarrhoea directly
  • The potential for antimicrobial drugs to be necessary in cases of persistent or severe diarrhea, particularly if there is evidence of infection

Given the guidelines and the context of treating diarrhea among homeless individuals, oral loperamide (Imodium) 4mg initially followed by 2mg after each loose stool (maximum 8mg/day) can help reduce symptoms, as supported by the study 1. Additionally, preventive measures such as using hand sanitizer, seeking clean drinking water sources, avoiding sharing personal items, and utilizing homeless shelter services that provide meals prepared with proper food safety standards are crucial in reducing the incidence of diarrhea in this population. Outreach workers should also distribute hygiene kits containing hand sanitizer, clean water, and OTC anti-diarrheal medication to support these efforts.

From the Research

Diarrhea in Homeless Populations

  • Diarrhea and consequent dehydration are common health issues affecting homeless infants and children, and if left untreated, can quickly become a medical emergency 2.
  • Education is a fundamental tool in the prevention of disease, and an educated parent may mean the difference between life and death for homeless children sick with diarrhea 2.

Oral Rehydration Solutions

  • The use of oral rehydration solution (ORS) has revolutionized the management of acute diarrhea, resulting in decreased mortality associated with acute diarrheal illnesses in children 3.
  • ORS has been used to decrease intravenous (IV) fluid requirements in patients with short bowel syndrome (SBS) who require parenteral nutrition (PN) 3.
  • A study found that administration of loperamide plus ORT for the management of traveler's diarrhea offered no benefit over administration of loperamide alone 4.

Homelessness and Health

  • On a single night in 2023, more than 653,000 people experienced homelessness in the United States, and health system efforts to address homelessness have included interventions such as screening for social needs and medical respite programs 5.
  • Initiatives using the Housing First approach to permanent supportive housing have a strong track record of success, and health care financing innovations using Medicaid Section 1115 waivers offer promising new approaches to improving health and housing for people experiencing homelessness 5.

Treatment of Diarrhea in Children

  • Oral rehydration solution (ORS) is the mainstay of treatment of acute watery diarrhoea, but it is underutilized in many hospitals, resulting in children with moderate degrees of dehydration being unnecessarily hospitalized and receiving intravenous fluids 6.
  • A study found that an ORS tolerance test can be used to assess the effectiveness of ORS in children with acute diarrhoea and moderate dehydration, and that children who tolerated ORS well were able to be successfully managed at home 6.
