What is Diarrhoea and causes of diarrhoea?
causes of diarrhoea is medically defined as the passage of three or more loose or liquid stools per day. While often temporary (acute), it is fundamentally a disturbance in the large intestine’s ability to absorb water, leading to watery and frequent bowel movements.
Acute episodes of diarrhoea typically last only a few days and resolve on their own. However, persistent or chronic diarrhoea lasting longer than four weeks requires specialized investigation to uncover the underlying causes of diarrhoea, such as Irritable Bowel Syndrome (IBS), Inflammatory Bowel Disease (IBD), or food intolerances. Understanding whether you are dealing with acute temporary discomfort or a chronic issue is the first step toward effective treatment.
Common causes of diarrhoea
Identifying the underlying causes of diarrhoea is vital for appropriate treatment. Most cases of acute diarrhoea are infectious, but several other factors can contribute:
1. Infections (Gastroenteritis)
- Viruses: Rotavirus, norovirus, and adenoviruses are the most frequent causes of diarrhoea, often referred to as “stomach flu.” They are highly contagious and spread quickly.
- Bacteria: Food poisoning from contaminated food or water often leads to bacterial diarrhoea. Common culprits include Salmonella, E. coli, and Campylobacter. Recognizing the presence of bacterial causes of diarrhea is important as they may require specific antibiotic treatment.
- Parasites: Less common, but parasites like Giardia can cause persistent, watery causes of diarrhoea.
2. Diet and Medication
- Medications: Many prescription drugs, especially antibiotics, are common causes of diarrhoea. Antibiotics disrupt the natural balance of gut bacteria, which can lead to antibiotic-associated diarrhoea.
- Food Intolerances: Conditions like lactose intolerance (inability to digest milk sugar) or gluten sensitivity can trigger diarrhoea after consuming the trigger food.
- Sweeteners: Excessive intake of artificial sweeteners (like sorbitol and xylitol) is also a known trigger.
3. Chronic Conditions
Chronic diarrhoea may be a primary symptom of underlying long-term diseases, including IBD (Crohn’s Disease or Ulcerative Colitis) or Celiac Disease. If you experience persistent diarrhoea, the causes of diarrhoea are unlikely to be simple infection and warrant specialist evaluation.
Signs of Dehydration
The most serious complication of diarrhoea is dehydration, especially in infants, the elderly, and those with weakened immune systems. When experiencing watery diarrhoea, the body loses large amounts of essential fluids and electrolytes quickly. Recognizing the subtle and severe signs of dehydration from diarrhoea is critical for timely intervention.
Mild to Moderate Dehydration
- Increased thirst and a dry mouth.
- Decreased urination; urine may appear darker and more concentrated.
- Fatigue and weakness.
- Dizziness or lightheadedness, particularly when standing up.
Severe Dehydration: (A Medical Emergency)
- Extreme thirst and lethargy (unusual tiredness or lack of energy).
- Little or no urination for eight hours or more.
- Sunken eyes or skin that lacks elasticity (if pinched, it stays tented).
- Rapid or weak pulse.
- In infants, a sunken soft spot (fontanelle) on the head.
If you suspect severe dehydration from diarrhoea, immediate medical attention is necessary.
When to Seek Medical Help
While most cases of diarrhoea can be managed at home, there are specific “Red Flag” symptoms indicating that the infection is severe, the dehydration is advanced, or the causes of diarrhoea are serious:
- Duration: causes of diarrhoea that lasts longer than two days (48 hours) without improvement.
- Fever: A high fever (above $38.5^\circ C$ or $101.5^\circ F$).
- Severe Pain: Intense abdominal or rectal pain.
- Stool Appearance: The presence of blood or black, tarry stools, or pus in the stool.
- Dehydration Signs: Any signs of severe dehydration from diarrhoea (e.g., lethargy, severe dizziness, little or no urination).
- Recent Travel: If the diarrhoea started shortly after international travel (may indicate unique bacterial causes of diarrhea).
Seeking help early ensures you receive the correct diagnosis, especially if bacterial causes of diarrhea are suspected, which may require specific acute diarrhoea treatment.
Home Management Tips
For typical, non-severe bouts of diarrhoea, home care focuses on hydration and rest. Implementing effective diarrhoea home remedies can significantly speed recovery.
1. Prioritize Rehydration
This is the most critical step in acute diarrhoea treatment. Do not rely solely on water, as the body also needs electrolytes (sodium, potassium).
- Oral Rehydration Solutions (ORS): ORS powders mixed with water are the best option, as they contain the optimal balance of water, sugars, and salts needed to counteract dehydration from diarrhoea.
- Clear Liquids: Broths, diluted fruit juices (to restore potassium), and sports drinks (diluted 50:50 with water) are acceptable diarrhoea home remedies.
2. Adjust Your Diet
Follow the “BRAT” diet or similar bland foods:
- Bananas (potassium)
- Rice (white, plain)
- Applesauce (pectin helps firm stool)
- Toast (white bread)
- Avoid dairy, spicy foods, fatty foods, high-fiber foods, and caffeine until the diarrhoea subsides.
3. Over-the-Counter (OTC) Medication
- Loperamide (Imodium): This medication helps slow down the frequency of bowel movements. However, avoid using Loperamide if you suspect bacterial causes of diarrhea or if there is blood in the stool, as slowing down the gut can trap the bacteria or toxins inside, potentially worsening the condition.
- Probiotics: These can help restore the natural balance of beneficial bacteria in the gut, aiding in recovery.
These diarrhoea home remedies and diet adjustments are key components of non-prescription acute diarrhoea treatment.
FAQs
Are antibiotics always necessary for diarrhoea?
No. Most cases are caused by viruses and do not respond to antibiotics. Antibiotics are only prescribed when there are strong signs of specific bacterial causes of diarrhea, such as severe symptoms or positive stool culture results.
Can stress be one of the causes of diarrhoea?
Yes. While stress doesn’t cause infectious diarrhoea, psychological stress can dramatically affect the gut through the gut-brain axis, leading to symptoms, particularly in those with IBS.
What is the best way to prevent dehydration from diarrhoea in children?
The best prevention is immediate, continuous use of Oral Rehydration Solutions (ORS) immediately after each loose stool. Monitoring for signs of dehydration from diarrhoea is constant.
What are the risks of using Loperamide (Imodium) for acute diarrhoea treatment?
Loperamide is generally safe for mild diarrhoea in adults, but it should not be used in children under two without a doctor’s recommendation. Its main risk is masking symptoms of a serious infection or hindering the body’s natural ability to flush out bacterial causes of diarrhea.
How long should I wait before using diarrhoea home remedies before calling a doctor?
If symptoms are mild, you can typically manage with diarrhoea home remedies and ORS for 24 to 48 hours. If the diarrhoea worsens, if a high fever develops, or if there is no improvement after 48 hours, seek medical attention.
