Why Diarrhea Happens

Diarrhea occurs when your digestive system moves waste through your bowels too quickly. Your body doesn’t absorb enough water from the stool, which creates watery stools or loose watery bowel movements.

Several factors trigger sudden diarrhea:

• Viral infections: Common stomach bugs spread easily and cause temporary digestive upset
• Bacterial infections: Food poisoning from contaminated food or water leads to severe symptoms
• Food intolerance: Lactose intolerance or sensitivity to artificial sweeteners causes digestive problems
• Medications: Antibiotics disrupt healthy gut bacteria and trigger loose stools
• Travel: Changes in food, water, or routine during travel affect your digestive system
• Irritable bowel syndrome: This chronic condition causes recurring digestive symptoms, including diarrhea

Diarrhea leads to dehydration because your body loses fluids and electrolytes rapidly. Understanding the cause helps you choose the right treatment approach.

What Stops Diarrhea Fast Naturally

Natural remedies can stop diarrhea quickly when you address hydration, diet, and gut health together. Here are the most effective strategies.

Rehydrate & Replace Electrolytes

Drinking plenty of fluids is your priority when treating diarrhea. Your body loses water and essential minerals with every loose bowel movement.

What to drink:

• Plain water (sip slowly throughout the day)
• Oral rehydration sachets from your local chemist
• Clear broths (chicken or vegetable)
• Coconut water (natural source of electrolytes)
• Sports drinks (dilute with water to reduce sugar)

What to avoid:

• Caffeine (coffee and strong tea increase fluid loss)
• Alcohol (worsens dehydration)
• Sugary soft drinks can worsen diarrhea. 
• Full-cream milk if you have lactose intolerance

Aim to drink small amounts frequently rather than large quantities at once. This helps your body absorb fluids better and prevents nausea.

Gentle, Binding Diet to Firm Stool

The BRAT diet helps firm up watery stools by providing easy-to-digest, bland foods. This short-term eating plan gives your gut time to recover.

The BRAT diet includes:

• Bananas: Rich in potassium and gentle on your stomach
• Rice: Plain boiled white rice absorbs excess water in your gut
• Applesauce: Provides pectin, which firms stool consistency
• Toast: Plain white toast without butter settles your digestive system

Other helpful foods:

• Plain crackers (saltines work well)
• Boiled potatoes without skin
• Plain pasta or noodles
• Steamed chicken (no seasoning or oil)

Foods to avoid:

• Greasy takeaway food (delays recovery)
• High-fibre foods (bran, whole grains increase bowel movement.)
• Spicy foods (irritate your digestive tract)
• Dairy products, if you suspect lactose intolerance
• Raw vegetables and fruits (except bananas)
• Artificial sweeteners (sorbitol and xylitol worsen diarrhea.)

Stick to small, frequent meals rather than three large meals. This approach is easier on your digestive system.

Probiotics & Gut Flora Support

Probiotics are beneficial bacteria that restore balance to your gut. They help stop diarrhea caused by antibiotics or disrupted gut flora.

Natural probiotic sources:

• Plain, unsweetened yoghurt (check label for live cultures)
• Kefir (fermented milk drink)
• Sauerkraut (fermented cabbage)
• Miso soup (fermented soybean paste)

Probiotic supplements:

Available at your chemist, these supplements contain specific bacterial strains. Look for products with Lactobacillus or Saccharomyces boulardii strains. These strains show the strongest evidence for treating diarrhea.

If you have a weakened immune system or take immunosuppressant medications, speak to your GP before using probiotic supplements. Some people need medical guidance for safe use.

Natural Soothing Remedies & Lifestyle Tips

Simple home remedies can calm your digestive system and reduce symptoms.

Helpful herbal teas:

• Ginger tea (reduces nausea and inflammation)
• Chamomile tea (soothes stomach cramps)
• Peppermint tea (relaxes digestive muscles)

Important lifestyle measures:

• Rest your body (allows energy for healing)
• Wash hands frequently (prevents spread of bacterial infections)
• Avoid food preparation for others until recovered
• Stay home from work if possible (prevents transmission)

Travel-related diarrhea prevention:

If you travel frequently or work FIFO, drink only bottled water in unfamiliar locations. Avoid ice cubes, raw salads, and street food in high-risk areas.

If symptoms persist after trying these remedies, speak to an Australian-registered doctor online for professional assessment.

When to See a Doctor or Online GP

Most diarrhea cases resolve naturally, but some situations need medical attention. Watch for these warning signs.

See a doctor immediately if you experience:

• Blood or mucus in your stool
• Black, tar-like bowel movements
• High fever above 38.5°C
• Severe abdominal pain or cramping
• Diarrhea lasting more than 48-72 hours
• Signs of severe dehydration (dizziness, dark urine, dry mouth, rapid heartbeat)
• Recent travel to high-risk countries
• Symptoms in infants, the elderly, or immunocompromised individuals

Chronic diarrhea concerns:

If you experience recurring episodes over several weeks, this may indicate irritable bowel syndrome, inflammatory bowel disease, or food intolerance. A GP can arrange proper testing and diagnosis.

FAQ’s

How fast does diarrhea usually clear up?

Most acute diarrhea cases resolve within 24 to 48 hours with proper hydration and rest. Viral gastroenteritis may last 2 to 3 days. If symptoms persist beyond 72 hours, consult a GP for assessment.

Can I stop diarrhea in 24 hours naturally?

Natural remedies can significantly improve symptoms within 24 hours. Focus on rehydration, the BRAT diet, and rest. However, complete resolution depends on the underlying cause. Bacterial infections may need antibiotics.

Is the BRAT diet still recommended in 2025?

Yes, the BRAT diet remains a useful short-term strategy for firming stools. However, doctors now recommend returning to a normal diet as soon as tolerated. Don’t restrict food for more than 24-48 hours.

Are probiotics safe if I’m on other medications?

Probiotics are generally safe for most people. However, if you take immunosuppressants, chemotherapy, or have a central line, consult your GP first. Probiotic supplements can interact with certain medical conditions.

Can children use these natural remedies?

Children can safely use most natural remedies with age-appropriate modifications. Oral rehydration solutions are essential for kids with diarrhea. The BRAT diet works well for children over 12 months. Always consult a GP if your child shows signs of dehydration or has bloody stools.

What’s the difference between diarrhea and food poisoning?

Food poisoning is a type of diarrhea caused by eating contaminated food. Symptoms often include vomiting, fever, and stomach cramps alongside watery stools. Food poisoning symptoms typically start 1-6 hours after eating the contaminated food.

Should I take Pepto Bismol or similar products?

Bismuth subsalicylate (Pepto Bismol) can help reduce diarrhea symptoms. However, it’s not suitable for everyone. Avoid this medication if you’re allergic to aspirin, take blood thinners, or have kidney problems. Natural remedies are often safer as a first approach.

When should I worry about dehydration?

Watch for dark yellow urine, decreased urination, dry mouth, dizziness when standing, and fatigue. Severe dehydration causes confusion, rapid heartbeat, and sunken eyes. Seek immediate medical help if you notice these severe symptoms.

Start Your Recovery Today

Diarrhea is uncomfortable, but most cases respond well to natural treatment. Start by rehydrating with oral rehydration solutions and water. Follow the BRAT diet for 24-48 hours. Add probiotics to support your gut health. These simple steps help your body recover naturally.

Monitor your symptoms closely. If diarrhea persists beyond 48 hours, contains blood, or causes severe dehydration, don’t wait. A professional medical assessment ensures you receive appropriate treatment.
