Oct 31, 2023

The realm of gut health often appears intricate and enigmatic. Amidst the buzz surrounding probiotics and their potential advantages for various health concerns, including digestion, questions may arise regarding whether these minuscule microorganisms can contribute to specific issues such as constipation.†

This article endeavors to unravel the essence of probiotics, investigate their association with constipation, and scrutinize potential side effects and safety measures.

What Are Probiotics?

Probiotics, comprising tiny living organisms like bacteria and yeasts, can positively impact our well-being when consumed. These beneficial microorganisms are commonly present in fermented foods like yogurt, kefir, sauerkraut, and kimchi. Alternatively, they are available in supplement form, providing convenient options to incorporate into your diet.

The Role of Probiotics in Digestion

How Probiotics Can Cause Constipation

Probiotics serve diverse roles in our digestion. Their primary function is to foster a thriving environment for beneficial bacteria. This microbial army aids the digestive process, ensuring smoother bowel movements and reduced symptoms like gas or bloating.


Constipation is a prevalent issue that can affect individuals of all ages. It leads to difficulties in regular bowel movements; medical experts typically define it as having fewer than three bowel movements per week. Additional constipation indicators encompass the strain during bowel movements and the passage of hard and dry stools. This condition may occur consistently or sporadically, with various underlying causes contributing to its occurrence.

Can Probiotics Cause Constipation?

Probiotic Effects

Despite their gut-friendly reputation, the intriguing paradox surrounding probiotics causing constipation stems from their initial usage. Studies have indicated that during the initial days of probiotic consumption, they can either directly trigger constipation or exacerbate existing conditions.†This phenomenon may occur when waste removal is slow, leading to constipation.

While probiotics are renowned for alleviating gas, bloating, and various digestive issues, the early stages of probiotic supplementation can sometimes pose challenges to gut health. The reassuring aspect is that most of these temporary adverse effects dissipate rapidly.

Causes of Constipation

Constipation can arise from a variety of factors, including:

  • Inadequate Fiber Intake
  • Insufficient Hydration
  • Sedentary Lifestyle
  • Stress
  • Medication Use
  • Underlying Medical Conditions, such as Hypothyroidism and Diabetes
  • Conditions like Irritable Bowel Syndrome (IBS)

Factors Influencing Probiotic Effects on Constipation

Probiotic Effects on Constipation

Various factors play a pivotal role in determining how probiotics impact constipation, including:

1. Types of Probiotics

The diverse spectrum of probiotic strains offers unique characteristics and health benefits. Lactobacillus and Bifidobacterium, two extensively studied strains, exhibit potential in alleviating constipation:

  • Lactobacillus: Certain Lactobacillus strains, such as Lactobacillus casei Shirota, commonly found in the gut and fermented foods with probiotics, may promote softer and more frequent stools.
  • Bifidobacterium: This prevalent probiotic strain may contribute to relieving constipation by increasing bowel movement frequency and addressing associated issues.

2. Individual Responses to Probiotics

The efficacy of probiotics can vary significantly from person to person. Genetics, gut health status, and dietary habits influence how a specific probiotic strain interacts with an individual’s body.

3. Effects on Various Constipation Types

Research has extensively explored probiotics’ impact on diverse constipation types, including:

  • Irritable Bowel Syndrome (IBS): Some probiotic strains have shown promise in alleviating constipation associated with IBS, leading to symptom reduction, improved bowel habits, and an enhanced overall quality of life.
  • Childhood Constipation: Constipation is not uncommon in children, driven by factors like diet, genetics, and psychological elements. Studies suggest positive outcomes when kids chewable probiotics are utilized to manage childhood constipation, resulting in increased stool frequency and improved stool consistency.
  • Pregnancy: Hormonal fluctuations and changes in physical activity levels during pregnancy can lead to constipation. Research indicates that womenís probiotics taken during pregnancy may facilitate regular bowel movements and alleviate constipation-related symptoms.
  • Medication-Induced Constipation: Certain medications, including opioids, iron supplements, and antidepressants, can induce constipation. Early research suggests that probiotics mitigate constipation triggered by specific drugs by promoting regular bowel movements and enhancing overall gut function.


Probiotics can be very helpful, but there are also some risks. It’s important to be aware of these risks to enjoy the benefits of probiotics safely.
