Does Lactobacillus Gasseri Benefit For Constipation

Does Lactobacillus Gasseri Benefit for Constipation?

Constipation is a common digestive problem affecting people of all ages, causing discomfort and impacting life quality. Some studies suggest that Lactobacillus Gasseri, a natural bacterium, helps alleviate constipation.

This article will explore scientific research on the benefits of Lactobacillus Gasseri for constipation and how to use it safely to improve effectiveness.


Key Takeaways

  • Lactobacillus Gasseri offers several benefits to digestive and gut health, such as preventing stomach ulcers, improving diarrhea conditions, increasing the amount of Bifidobacteria in the gut microbiota, and promoting a balance of microflora.
  • Lactobacillus Gasseri benefits constipation by reducing harmful bacteria (Prevotella), enhancing beneficial bacteria, decreasing colon pH, and stimulating colonic motility.
  • Lactobacillus Gasseri can be supplemented through fermented foods like yogurt, sauerkraut, kimchi, or dietary supplements. It's advisable not to use L. Gasseri simultaneously with antibiotics.
  • Pregnant women, nursing mothers, recent organ transplant patients, and those allergic to dairy should consider carefully before supplementing with L. gasseri products.
  • Maintaining a fiber-rich diet, drinking plenty of water, regular bowel movements, and frequent exercise can help alleviate constipation.

Understanding Constipation

Constipation is a health issue related to bowel movements, where a person cannot defecate regularly (less than three times a week) or struggles during defecation.

Constipation remains a common digestive issue, with over 2.5 million doctor visits annually and about 4 million people in the United States experiencing frequent constipation.

What Causes of Constipation

the cause of constipation

First, let's explore the mechanism behind the formation of feces in the body. As food moves through the colon, the colon absorbs water from it. Subsequently, muscle contractions push the stool toward the rectum.

By the time it reaches the rectum, most of the water has been absorbed, making the stool dry, hard and difficult to pass.

This mechanism points to several causes of constipation, such as a lack of fiber, inadequate water intake, unhealthy eating habits and lifestyle, and lack of exercise.

Additionally, changes in living conditions (like pregnancy, travel, and aging) or the effects of medications, especially the misuse of laxatives, can lead to constipation.

Symptoms of Constipation

Constipation sufferers often experience symptoms such as defecating less than three times per week, hard, dry, lumpy stool, difficulty passing stools, and pain during bowel movements.

They may also feel bloated and nauseous, suffer from abdominal pain and cramps, and have a sensation that not all stool has been passed after going to the toilet.

What are the Benefits of Lactobacillus Gasseri for Digestive Health and Gut Health

Lactobacillus Gasseri Benefits For Constipation

Lactobacillus Gasseri is a probiotic bacterium belonging to the Lactobacillus family.

It's naturally found in the digestive and urinary tracts, inhibiting harmful bacteria, breaking down food, and absorbing nutrients. These bacteria can be found in fermented dairy foods or supplements.

Lactobacillus Gasseri offers significant health benefits, particularly for digestive and gut health.

It has been shown to prevent stomach ulcers by reducing Helicobacter pylori infections and improving diarrhea conditions [1].

Additionally, L. gasseri benefits patients with irritable bowel syndrome (IBS), helping control ulcerative colitis inflammatory bowel disease (IBD) [2] and significantly increasing the amount of Bifidobacteria in the gut microbiota, a well-known beneficial bacterium that improves bowel movement, supports immune health, and promotes regular defecation [3].

Although individual research evidence on L. gasseri is limited, its ability to modulate the gut microbiota cannot be denied.

Several studies also indicate that Gasseri regulates the balance of gut microbiota, controlling the risk of being overweight [4].

The Science Behind Lactobacillus Gasseri and Constipation

In a study conducted by supplementing probiotic-fermented yogurt containing Lactobacillus Gasseri to Kunming mice with constipation [5], it improved the secretion of GI-regulating peptides in serum and neurotransmitter substances, increased the expression of c-kit and SCF proteins, meanwhile adjusting the structure of gut microbiota and SCFA levels.

Additionally, L. Gasseri facilitated bowel movements, reduced the presence of harmful bacteria, Prevotella, and increased the abundance of beneficial bacteria such as Lactobacillus, Oscillospira, Ruminococcus, Coprococcus, and Akkermansia.

Gasseri could contribute to developing functional foods to improve human gut health.

A study was conducted to ensure the use of probiotics, including L. gasseri, to manage constipation.

It demonstrated its effectiveness in reducing the transit time through the colon, decreasing intestinal pH, and thereby enhancing colonic movement, which is beneficial for patients with constipation [6].

How to Use Lactobacillus Gasseri for Constipation

way to use lactobacillus gasseri to reduce constipation

As discussed above, Lactobacillus Gasseri is a beneficial bacterium found in the gut, known for improving digestion and reducing constipation. How, then, should Lactobacillus Gasseri be used to treat constipation?

Currently, L. gasseri is widely available in various functional foods. Depending on the specific product, you can supplement L. gasseri in capsules, tablets, or powder with the recommended dosage. However, the human body requires 1 to 10 billion colony-forming units (CFU) daily.

Also, remember to include yogurt in your diet. Yogurt is a fermented milk product with microorganisms containing Lactobacillus Gasseri, suitable for daily consumption.

Other fermented foods like sauerkraut, kimchi, tempeh, or whole grains, fruits, and vegetables also provide a good source of Lactobacillus Gasseri while also supplying prebiotics - a type of fiber that feeds beneficial bacteria in the gut.

Dosage and Recommendations You Need to Know about Lactobacillus Gasseri for Constipation

There is no specific recommended dosage for Lactobacillus Gasseri. The strength of Lactobacillus supplements is often expressed in colony-forming units (CFU), an indicator identifying the number of living organisms per capsule or tablet.

The human body requires 1 to 10 billion colony-forming units to maintain and stabilize the gut microbiota balance.

Carefully read the ingredients list of each supplement product, or consult a doctor or healthcare professional to determine the appropriate consumption method and dosage.

Note that antibiotics can reduce the effectiveness of probiotic supplements.

Therefore, avoid using them simultaneously or space probiotic doses about 2 hours apart from antibiotics to achieve the best effect [7].

Potential Side Effects and Precautions When Taking Lactobacillus Gasseri

things need to know when using lactobacillus gasseri

No specific study has proven the short-term or potential side effects of Lactobacillus Gasseri supplements.

In some cases, L. gasseri could cause bloating and abdominal distention. However, most occur mildly and result from the body's adaptation mechanism.

Though not potentially harmful in side effects, when supplementing with Lactobacillus Gasseri, consider a few issues to prevent undesirable consequences:

  • There's no definitive confirmation about the absolute safety of L. gasseri during pregnancy or lactation. Consult a doctor or gynecological expert to fully understand the benefits and risks before using probiotics during this stage.
  • Probiotic products are generally not recommended for individuals with compromised immune systems, HIV infections, those who have undergone organ transplantation, or those undergoing cancer treatment with immunosuppressive drugs.
  • Some L. gasseri supplement products may contain traces of milk protein, so those with milk allergies should take caution.
  • L. gasseri bacteria could overgrow if the immune system is compromised, potentially causing heart and heart valve infections, so consult a healthcare professional before using probiotics.

Other Natural Remedies for Constipation

Lifestyle, activities, and diet greatly influence constipation.

To prevent constipation, besides supplementing with beneficial bacteria like Lactobacillus Gasseri, maintain a diet rich in fiber from vegetables, fruits, whole grains, or legumes. Fiber retains water in the stool, facilitating more effortless bowel movement.

Additionally, drink at least 2 liters of water daily, exercise regularly, limit alcohol, caffeine, and laxatives, eat complete meals, allocate time for defecation, and apply massage therapies to support the digestive system.


Constipation not only causes discomfort to the body but also affects daily life and activities.
