Introduction

Our gut, often referred to as our second brain, is a marvel of biological engineering.

Beyond its primary role in digestion, it holds the keys to our overall health, affecting everything from our immune system to our mood.

With modern science diving deeper into the intricate world of gut microbiota, the spotlight has increasingly shifted toward three key players: prebiotics, probiotics, and synbiotics.

These elements have shown tremendous promise in addressing one of the most common, yet overlooked, health challenges we face today: constipation.

This article endeavors to unravel the potent capabilities of these microbial wonders, highlighting their significance in promoting optimal gut health and battling the discomforts and complications of chronic constipation.

Join us as we delve into the fascinating intersection of biology, nutrition, and health, exploring the power these compounds wield in unlocking a healthier, more balanced digestive system.

Decoding the Gut's Response: Prebiotics, Probiotics, and Synbiotics in Constipation

Prebiotics, probiotics, and synbiotics have been researched for their effects on chronic constipation (CC).

Let's delve into how they possibly work:

Prebiotics

These mainly fuel the growth of good bacteria in the gut, such as Lactobacillus and Bifidobacteria.

This process results in the production of short-chain fatty acids (SCFAs), like butyrate. Increased SCFAs can enhance gut motility and reduce symptoms of constipation.

However, the overall effect of prebiotics on SCFA levels remains debated, as different prebiotic types have varied effects and SCFAs can be quickly absorbed, making measurements challenging .

Probiotics and Synbiotics

These can have even broader effects on the gut microbiota than prebiotics alone.

SCFAs produced by these compounds can stop the growth of harmful bacteria .

For instance, L. plantarum ZS2058 was found to thwart the growth of Salmonella by elevating propionic acid in mice.

Additionally, SCFAs influence anti-inflammatory actions in the gut by regulating cell behavior and suppressing inflammation.

Specific probiotic strains can further shift the immune response from a pro-inflammatory to an anti-inflammatory state, aiding bowel movements .

SCFAs also increase substances like peptide YY (PYY) and glucagon-like peptide-1 (GLP-1), which promote bowel movements .

Interestingly, high SCFA levels have been linked to obesity concerns.

Enhancing Intestinal Health

Probiotics can boost mucus secretion, assisting in stool passage and providing a protective barrier against pathogens .

They also fortify the gut barrier, reducing the chances of harmful bacteria attaching to the intestinal walls.

If harmful bacteria are detected, probiotics can prompt the production of antimicrobial peptides (AMPs) that act against these pathogens, as demonstrated by L. acidophilus and L. fermentum's ability to inhibit certain harmful strains.

Furthermore, probiotics can potentially reduce inflammation associated with constipation, as some constipated individuals exhibit inflammatory responses.

They also encourage the release of immunoglobulin A (IgA), which combats bacterial toxins in the gut.

Synbiotics

As a combination of prebiotics and probiotics, synbiotics harness the benefits of both.

They could promote SCFA production, improve the integrity of the intestinal barrier, and balance gut microbiota.

However, compared to prebiotics and probiotics, our understanding of synbiotics is still in its infancy.

In summary, prebiotics, probiotics, and synbiotics play crucial roles in regulating gut health.

While their precise mechanisms of action need further research, their potential benefits in addressing constipation and overall gut health are promising.

The Link Between Probiotics, Genetics, and Constipation

Serotonin (5-HT) plays a vital role in regulating bowel movements.

The serotonin-selective reuptake transporter (SERT) controls its levels by recycling 5-HT.

However, genetic variations, called polymorphisms, in the SERT gene can affect how it functions.

These polymorphisms lead to two versions: insertion (L) and deletion (S).

Studies found that certain combinations, like S/S, might reduce 5-HT reuptake, leading to increased 5-HT levels, which has been linked to constipation .

Specifically, the research found that patients with cancer or irritable bowel syndrome (IBS) carrying this S/S gene variation have higher constipation risks. This polymorphism can lower the serotonergic effect, causing constipation.

Interestingly, certain probiotics, like L. acidophilus and B. longum, have been observed to increase SERT expression in intestinal tissues.

An RCT by Riezzo highlighted that patients with the S version of the 5-HTTLPR in the SERT gene experienced reduced 5-HT levels after taking Lactobacillus reuteri (LR) DSM 17938.

This suggests that such patients might benefit from this probiotic supplementation.

In essence, while there's potential in understanding how probiotics can help certain genetic profiles combat constipation via 5-HT pathways, more research is needed to fully unravel these connections.

Research increasingly shows that probiotics may play a role in treating constipation.

Notably, the B. lactis strain seems to enhance defecation regularity and stool consistency, but results across studies have been varied and sometimes contradictory .

This inconsistency arises because different studies use different methods, dosages, and treatment durations.

Moreover, many studies don't account for key factors influencing constipation, such as age, gender, diet changes, physical activity, and alcohol consumption.

These elements significantly affect gut health and should be considered when analyzing the effects of probiotics.

A recurring issue in research is the grouping of various types of constipation.

In examining 26 human studies, six failed to specify the kind of constipation in participants, and the remaining only considered functional constipation, without diving into its subtypes.

Grouping different constipation types might obscure the true impact of probiotics and lead to varied results.

Despite these complexities, many healthcare professionals are starting to see the value of probiotics in treating constipation.

A global survey of over 1,000 healthcare professionals revealed that 79% had suggested probiotics to their patients, and in a separate survey, 18% of primary care professionals recommended them specifically for constipation .

Among the various strains, B. lactis primarily aids defecation regularity, while L. casei Shirota probiotics address multiple constipation symptoms.

Although the best strain and dosage aren't definitive yet, starting with a daily dose of 10⁹ CFU seems promising, with individual monitoring for adjustments.

However, solely relying on probiotics without addressing lifestyle and diet isn't recommended, as these also influence gut health and constipation severity.

Probiotic supplements should be complemented with dietary guidelines and physical activity suggestions.
