Is Buttermilk Good for Diarrhea? Benefits & Risks

Summary

Buttermilk can be helpful during diarrhea recovery but is not recommended during active, watery diarrhea.

Plain buttermilk contains probiotics that support gut bacteria, but it also contains lactose, which the gut may temporarily struggle to digest during diarrhea.

Whether buttermilk helps or worsens symptoms depends on the stage of diarrhea, preparation, and individual tolerance.

Introduction

Buttermilk (chaas) is widely consumed in India for digestion and cooling the stomach.

Many people turn to buttermilk during stomach upset, believing it will settle loose motions.

However, during diarrhea, the gut behaves differently.

Understanding when buttermilk helps—and when it harms—can prevent prolonged symptoms.

Why Buttermilk May Help During Diarrhea

1) Contains Beneficial Bacteria

Buttermilk made from curd contains probiotics that may help restore gut bacteria after mild infections.

2) Lighter Than Milk

Buttermilk is diluted and fermented, making it easier to digest than plain milk for many people.

3) Supports Digestion During Recovery

Once stools start firming up, buttermilk may help normalise digestion.

Why Buttermilk Can Worsen Diarrhea

1) Temporary Lactose Intolerance

During active diarrhea, the gut may not digest lactose well—even in buttermilk—leading to more loose stools.

2) Added Spices and Salt

Traditional buttermilk often contains salt, ginger, curry leaves, or spices, which can irritate an inflamed gut.

3) Cold Temperature

Cold buttermilk can stimulate bowel movement and worsen cramps.

When Buttermilk Is Okay During Diarrhea

Diarrhea is mild or improving
No vomiting
You usually tolerate curd well
Buttermilk is plain and taken in small amounts

When Buttermilk Should Be Avoided

How to Take Buttermilk Safely During Diarrhea

Dilute well with water
Avoid spices, tempering, and excess salt
Drink at room temperature

Buttermilk vs ORS: Important Difference

Buttermilk supports gut bacteria but does not prevent dehydration.

ORS replaces water and electrolytes
Buttermilk does not meet hydration needs during diarrhea

Best approach: ORS first, buttermilk only during recovery if tolerated.

Better Alternatives Than Buttermilk During Active Diarrhea

ORS
Rice water
Plain water in small sips
Soft foods like rice or banana
