Drugs for Treatment of Diarrhea-Predominant IBS01:17

Drugs for Treatment of Diarrhea-Predominant IBS

641
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Drugs for Treatment of Constipation-Predominant IBS

750
Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...

Chronic Pharyngitis01:23

Chronic Pharyngitis

11.3K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Chronic Pancreatitis I: Introduction

682
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

755
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Summary

Evaluating chronic diarrhea in older adults requires considering age-specific conditions and atypical presentations. A stepwise diagnostic approach is practical and effective for identifying causes in the elderly.

Area of Science:

  • Gastroenterology
  • Geriatrics
  • Internal Medicine

Background:

  • Chronic diarrhea presents diagnostic challenges, particularly in elderly individuals.
  • Older adults may have increased risk for certain structural disorders and atypical disease presentations.

Purpose of the Study:

  • To review the evaluation of chronic diarrhea in older individuals.
  • To highlight conditions more frequent in the elderly and valuable diagnostic tests.
  • To present a practical and affordable approach to diagnosis.

Main Methods:

  • Review of existing literature on chronic diarrhea in the elderly.
  • Discussion of differential diagnoses and diagnostic strategies.
  • Analysis of the utility of diagnostic tests in this population.

Main Results:

  • Distinguishing functional diarrhea from irritable bowel syndrome with diarrhea (IBS-D) may have limited value in older adults.
  • Older individuals may have higher risks for structural disorders and atypical presentations.
  • Conventional diagnostic algorithms are generally effective, but validation in the elderly is needed.

Conclusions:

  • A thoughtful analysis of potential causes and a stepwise approach are crucial for managing chronic diarrhea in the elderly.
  • While specific validation is lacking, established diagnostic methods can lead to accurate diagnoses.
  • Further research is needed to quantify disease likelihood and test performance in older patients.
