Diarrhea describes loose, watery, and frequent bowel movements. It is a very common problem that usually resolves on its own within a few days, but it can sometimes indicate a more serious underlying issue.
⏱️ Types of Diarrhea
Acute Diarrhea:
Lasts for a short time (usually 1 to 2 days).
Usually caused by a viral or bacterial infection (often called "stomach flu" or food poisoning).
Persistent Diarrhea:
Lasts between 2 and 4 weeks.
Chronic Diarrhea:
Lasts for at least 4 weeks.
Usually a symptom of a chronic disease like IBS (Irritable Bowel Syndrome), IBD (Crohn's or Colitis), or Celiac disease.
🦠 Common Causes
Viruses: The most common cause. Examples include Norovirus, Rotavirus (common in children), and Adenovirus.
Bacteria and Parasites: Usually ingested through contaminated food or water. Common culprits are E. coli, Salmonella, and Giardia.
Medications: Many drugs, especially antibiotics, can disturb the natural balance of bacteria in your intestines.
Food Intolerances:
Lactose Intolerance: Inability to digest the sugar in milk.
Artificial Sweeteners: Sorbitol and mannitol (found in chewing gum) can cause issues.
Digestive Disorders: IBS, Crohn's disease, Ulcerative Colitis, or Celiac disease.
⚠️ Symptoms
Aside from loose stools, diarrhea is often accompanied by:
Stomach cramps and pain
Bloating
Nausea or vomiting
Urgency (sudden need to go to the toilet)
Fever (if there is an infection)
The Major Risk: Dehydration 💧
Diarrhea causes your body to lose fluids and electrolytes quickly. Dehydration is the biggest danger, especially for young children and older adults.
Signs of Dehydration:
Excessive thirst
Dry mouth or skin
Little or no urination
Dark yellow urine
Weakness, dizziness, or lightheadedness
🛡️ Prevention
Hand Washing: Wash hands frequently with soap and water, especially after using the toilet and before eating.
Food Safety: thoroughly cook meat and eggs. Wash fruits and vegetables.
Travel Care: When traveling to developing countries, drink bottled water and avoid raw foods or street vendors (to prevent "Traveler's Diarrhea").
