Diarrhoea

Origine

​

Introduction

Diarrhoea is a common disorder of the digestive system, manifested by frequent liquid stools. Although often benign, it can become serious, particularly in children and the elderly, due to the risk of dehydration. Understanding the origin, mechanism, types and treatments of diarrhoea is essential if it is to be managed effectively.

Origine of diarrhoea

• The causes of diarrhea are numerous and can be classified into several categories:

Infectious :

• Bacterial: Salmonella, Escherichia coli, Shigella.

• Virales : Rotavirus, Norovirus.

• Parasitaires : Giardia lamblia, Entamoeba histolytica.

Non-infectious :

• Food : Lactose intolerance, food allergies.

• Médicamenteuses : Antibiotiques, laxatifs.

• Inflammatory :Inflammatory bowel diseases (IBD) such as Crohn's disease and ulcerative colitis.

• Functional: Irritable bowel syndrome (IBS).

Mechanism of Diarrhea

• Diarrhea occurs when the balance between water absorption and secretion in the intestine is disturbed. Main mechanisms include:

• Osmotic diarrhea :

       Occurs when unabsorbed substances                 draw water into the intestine. Examples                 include sorbitol ingestion or lactose

       malabsorption.

• Secretory diarrhea :

       Results from excessive secretion of water             and electrolytes in the intestine. Bacterial             infections, such as cholera, are a frequent           cause.

• Inflammatory diarrhea:

       Due to inflammation of the intestinal                     mucosa, often caused by inflammatory               diseases or invasive infections.

• Motor diarrhea :

       Caused by increased intestinal motility,               often due to functional disorders such as             IBS.

Types of Diarrhea

Diarrhea can be classified into several types according to its duration and characteristics:

• Acute diarrhea :

       Lasts less than two weeks. It is often caused         by infection or food poisoning.

• Persistent diarrhea :

       Lasts two to four weeks. It may be caused           by persistent infections or underlying                   digestive disorders.

• Chronic diarrhea :

       Lasts more than four weeks. Causes                     include inflammatory diseases,

       malabsorption disorders and certain

       cancers.

Treatment of Diarrhea

Treatment of diarrhea depends on its cause and severity:

• Rehydration :

       Essential for preventing and treating

       dehydration. Oral rehydration solutions

       (ORS) containing electrolytes are

       recommended.

• Food and water :

       In the event of acute diarrhoea, it is                       advisable to continue eating light, easily

       digestible foods. The BRAT diet (bananas,

       rice, applesauce, toast) is often

       recommended.

• Medicines :

       Antidiarrhoeals: such as loperamide, to                 reduce intestinal motility.

• Antibiotics : Prescribed in cases of confirmed bacterial infection.

• Probiotics : To restore intestinal flora, particularly after infectious or antibiotic-related diarrhoea.

• Treatment of the underlying cause :

       Identification and management of specific         causes such as food intolerances,                         inflammatory diseases or parasitic                       infections.

Prevention

To prevent diarrhea, it is crucial to maintain good hygiene:

• Wash your hands regularly.

• Eat well-cooked food and drink clean water.

• Avoid potentially contaminated food and drink, especially when traveling.

Conclusion

Diarrhea, although common, can have a variety of causes, some of them serious. A thorough understanding of its origins, mechanisms, types and treatments enables effective management and prevention of complications. Rehydration and hygiene are the cornerstones of prevention and initial treatment, while specific management depends on identifying the underlying cause.

Lagamid is a good diarrhea medication. It is fast-acting and effective. Widely used for travelers' diarrhea, it helps regulate the intestinal tract. But bear in mind that diarrhea, which is a symptomatic reaction to digestion, always (or almost always) has a cause, with various origins, some of which may be infectious.
