The Causes of Diarrhea and How to Find Lasting Relief

Summary

Diarrhea isn’t always just a temporary issue; it can be a sign that something deeper is going on. It’s important to understand the causes, whether it’s due to gut infections, poor absorption, stress, or an imbalance in gut bacteria. While acute diarrhea is usually short-lived, chronic diarrhea could indicate more serious digestive issues.

Rather than relying on over-the-counter meds that only mask the issue, focusing on the root causes can lead to lasting relief. Ayurveda suggests balancing digestion by addressing absorption and strengthening the gut’s rhythm, not just stopping diarrhea. Mool Health offers a holistic approach, targeting the cause with personalized plans to heal the gut from within.

Introduction

Diarrhea is more than a temporary digestive issue; it is often your body’s way of warning you that something is off. The causes of diarrhea can range from a one-time reaction to contaminated food to more complex conditions, including long-term gut imbalance, hyperactive gut mobility, disruption of the gut-brain axis, or damage to the gut lining.

By understanding these reasons for diarrhea**,** you can determine whether it is a temporary condition or a recurring issue that requires more comprehensive care. Keep reading this blog to know more.

When Diarrhea is Normal vs. When it's Not?

Not every case of loose stool is a cause for concern. It can often be linked to something as simple as eating out, a mild stomach bug, or even stress. Depending on how severe it is, it typically falls into two categories:

• Acute diarrhea: It is a loose, watery diarrhea that lasts one to three days, typically associated with food, water, or a short-term infection.

• Chronic diarrhea: It occurs weekly or monthly, indicating deeper digestive or systemic issues.

You should be concerned if diarrhea happens more than three times a week, even when you're eating light, balanced meals, or if your stools remain consistently loose, unpredictable, or urgent. When these patterns occur, it’s a sign that it might be time to dig a little deeper and move beyond just surface-level solutions.

Top 5 Root Causes of Repeated Diarrhea

Here are the top five causes of diarrhea**:**

• Gut Infections (Acute)

Gut infections are one of the most common causes of sudden diarrhea. You can catch them from contaminated food, water, or close contact with an infected person. Viral infections such as norovirus, rotavirus, adenovirus, astrovirus, and bacterial infections like E. coli or Salmonella can cause severe loose motions, often accompanied by fever, nausea, and dehydration.

Antimobility tablets may reduce the intensity of issues, but the gut may still take weeks to recover fully.

• Weak Absorption/Gut Lining Damage

Damaged or inflamed gut lining is one of the major causes of loose motion**.** When the gut lining becomes inflamed or damaged, it cannot absorb water and nutrients properly. This leads to watery stools and contributes to the loose motion. Triggers may include acidity, excessive spicy food, prolonged stress, or even a past untreated infection.

While medications can temporarily reduce frequency, true recovery requires repairing the gut lining itself.

• Hyperactive Motility

Sometimes food moves too quickly through the intestines, leaving little time for absorption. Stress, caffeine, raw foods, or irritable bowel syndrome often trigger this. A classic example is stress diarrhea, where you need to use the toilet within 30 minutes of eating.

While antispasmodic medicines can slow the urgency, they do not correct the underlying motility imbalance.

• Imbalanced Gut Bacteria (Dysbiosis)

Your gut relies on a balance between good and bad bacteria for proper digestion. When you get diarrhea after eating antibiotics, junk food, or high sugar, it is because these items disrupt the balance of good and bad bacteria, thus resulting in bloating, indigestion, vomiting, and more.

To aid the gut flora recover, it is better to rely on probiotics, prebiotics, and dietary changes, as over-the-counter tablets may not be that effective.

• Gut-Brain Axis Disruption (Stress-Induced Diarrhea)

Stress and anxiety play a powerful role in digestion. Work or school deadlines, emotional strain, or frequent travel can send distress signals from the nervous system to the gut, triggering urgency and loose stools. This gut-brain imbalance is one of the most common causes of diarrhea, especially in conditions like IBS (Irritable Bowel Syndrome), which leads to frequent stomach pain and changes in bowel habits. The mind and gut are closely connected, and when stress is high, it can disrupt normal digestion and exacerbate issues.

Ayurvedic Perspective on Diarrhea

In Ayurveda, diarrhea is known as Atisaar and is classified into Pitta, Vata, or Ama types depending on its nature:

• Pitta-type: Characterized by a burning sensation, urgency, and yellowish stool. The common mistake here is focusing only on cooling foods to ease issues, without addressing the root issue of healing the gut lining.

• Vata-type: Involves watery stools, frequent urgency, and noisy digestion. Many people tend to rely solely on binding foods to manage issues, instead of addressing the underlying motility imbalance.

• Ama-type: Often involves foul-smelling stools with undigested food. Over-the-counter remedies may temporarily mask issues but don’t improve overall digestion or address the deeper digestive issues.

Ayurveda focuses on restoring digestive balance rather than simply stopping diarrhea. The approach aims to correct absorption, improve the gut’s rhythm, and strengthen the digestive fire (Agni). By addressing these core issues, Ayurveda seeks to promote overall digestive health and prevent future imbalances, rather than just offering temporary relief.

Why Market Tablets Offer Only Temporary Relief?

Over-the-counter anti-diarrheal tablets may provide quick relief, but they rarely address the root cause. By simply slowing gut movements, they mask the problem without healing your digestive system. If you rely on these repeatedly, the underlying reasons for diarrhea remain unresolved, leading to cycles of discomfort.

For example, Loperamide (Imodium) slows gut movement, which can ease problems, but if diarrhea is due to a microbial infection, it may trap harmful bacteria, worsening the condition. Norflox-TZ, an antibiotic, kills harmful bacteria but also destroys beneficial gut microbes, potentially leading to long-term dysbiosis and recurrent loose motions.

Oral rehydration solutions (ORS) help replace lost fluids and electrolytes, preventing dehydration, yet they do not restore gut balance or fix the underlying cause. These examples highlight why issue-focused approach alone is insufficient for lasting gut health.
