Diarrhea

Diarrhea is a condition characterized by frequent loose or watery stools. Generally, it is defined as having three or more loose stools in one day. Even a single stool containing mucus or blood qualifies as diarrhea. Symptoms usually appear suddenly and last for a short period, typically no more than two to three days (known as acute diarrhea), and often resolve on their own. However, if symptoms persist for more than 2-4 weeks (chronic diarrhea), it may indicate an underlying health issue.
A serious complication of diarrhea is dehydration and electrolyte imbalance, as the body loses water and minerals quickly through diarrhea and vomiting. This can be life-threatening, especially in young children and elderly people whose bodies are weaker.

Advice when experiencing diarrhea

Do not take anti-diarrheal medication as it may prevent the body from expelling harmful pathogens. It is recommended to sip oral rehydration salts (ORS) frequently to replace lost fluids and electrolytes. Eat soft, easily digestible foods and avoid spicy foods, dairy products, raw or undercooked foods, and fermented foods.
Symptoms usually improve within 24-48 hours. However, if symptoms persist or worsen, seek medical attention immediately. Avoid self-medicating, as this may worsen the condition.
