Laxatives can have a harmful impact on gut bacteria, with research showing that they can cause long-lasting changes to the gut microbiome.
Laxatives are fast-acting remedies for constipation, with several different types available, including osmotic, bulk-forming, and lubricant laxatives. While they can provide short-term relief, they may also have long-term consequences for overall health.
Recent studies have shown that laxatives can negatively impact the microbiome, which is the balance of bacteria in the body. The microbiome plays a vital role in digestion, elimination, and other essential functions. When this balance is disrupted, it can lead to a range of issues, including mental disorders and adrenal fatigue syndrome.
Research on mice has found that laxatives can cause certain microbes to flourish while hindering the growth of others that are essential for good health. Specifically, a microbial family known as S24-7 was nearly driven to extinction, and the overall diversity of gut bacteria was reduced. Additionally, laxatives were found to have an impact on the immune system, causing a thinning of the mucus that protects the gut lining.
Similar results have been observed in humans, with changes in the microbiota persisting for a month after a pre-colonoscopy enema. Laxative abuse is particularly common among individuals with eating disorders and can lead to serious health complications, including organ failure, prolapse, and even death.
Overall, while laxatives can provide temporary relief from constipation, they can also have detrimental effects on gut bacteria and overall health. It is important to consider these potential negative consequences before resorting to laxatives as a solution for irregular bowel movements.

Laxatives can cause a loss of beneficial gut bacteria, leading to dysbiosis and gastrointestinal issues
Laxatives can have a detrimental impact on gut bacteria, leading to dysbiosis and gastrointestinal issues. Dysbiosis refers to an imbalance in the gut microbiome, which can have far-reaching consequences for health.
The gut microbiome is a complex ecosystem comprising billions of bacteria that play crucial roles in digestion, elimination, and other bodily functions. A healthy balance of gut bacteria is essential for maintaining overall health and well-being. However, the use of laxatives can disrupt this delicate balance.
Research has shown that laxatives can cause a loss of beneficial gut bacteria, leading to dysbiosis. This imbalance can result in a range of gastrointestinal issues, including constipation, diarrhoea, and irritable bowel syndrome. Laxatives can also increase intestinal permeability, allowing more substances to move from the gut into the bloodstream, potentially leading to inflammation and other health issues.
One study found that the use of laxatives in mice led to a significant decrease in the microbial family S24-7, which is involved in carbohydrate fermentation. This depletion of beneficial bacteria can have long-lasting effects on gut health and diversity. Additionally, laxatives have been shown to thin the mucus layer that protects the gut lining, potentially compromising the immune system and triggering an immune response.
The impact of laxatives on the gut microbiome is not limited to the short term. Studies have found that changes in the gut microbiome persisted for up to a month after laxative use, indicating the potential for long-term consequences. It is important to note that the severity of these changes was influenced by the dose and duration of laxative use.
Furthermore, laxative abuse, particularly in individuals with eating disorders, can lead to severe health complications. Laxatives are often misused as a method of weight control, despite being ineffective for this purpose. The abuse of laxatives can result in dehydration, electrolyte imbalances, and a loss of beneficial gut bacteria, increasing the risk of gastrointestinal issues and chronic diseases.
To mitigate the negative impacts of laxatives on the gut microbiome, it is essential to prioritise gentler and more natural solutions for constipation. Probiotics containing Lactobacilli cultures can help restore the natural balance of gut bacteria. Additionally, incorporating gut-healthy foods, such as oily fish, whole grains, fruits, vegetables, and pulses, can promote a diverse and healthy gut microbiome. Adequate water intake and regular exercise can also help improve bowel movements without resorting to laxatives.

Laxatives can deplete the body of essential electrolytes and minerals, including potassium, sodium, magnesium and phosphorus
Laxatives are intended to provide relief from constipation. However, their overuse can lead to severe health issues, including the depletion of essential electrolytes and minerals such as potassium, sodium, magnesium, and phosphorus. This is because laxatives can cause the body to lose water, leading to dehydration, which in turn can cause electrolyte imbalances. Electrolytes are essential minerals that play a crucial role in nerve and muscle function, including the heart.
When an individual takes laxatives, their body loses water, which can lead to dehydration. Dehydration can cause a range of health issues, including tremors, fainting, weakness, and blurred vision. It can also lead to severe organ damage and even death.
Laxatives can also disrupt the balance of electrolytes in the body. Electrolytes such as potassium, sodium, and calcium are essential for regulating nerve and muscle function, including the heartbeat, blood pressure, and muscle movements. Over time, electrolyte imbalances can negatively affect the kidneys and heart. In some cases, electrolyte loss can lead to fatal complications such as coma, seizures, and cardiac arrest.
In addition to the risk of dehydration and electrolyte imbalances, laxative abuse can also contribute to gastrointestinal discomfort, gas, loose stool, and diarrhoea. It can also cause rectal irritation and increase the risk of infection and bleeding during bowel movements.
Furthermore, laxatives can deplete the body of essential minerals such as magnesium and phosphorus. Magnesium plays a crucial role in nerve and muscle function, energy production, and the maintenance of bone health. Phosphorus is also important for bone health and is a component of DNA and RNA, the body's genetic material.
Overall, while laxatives can provide short-term relief from constipation, their overuse can lead to severe health complications, including the depletion of essential electrolytes and minerals such as potassium, sodium, magnesium, and phosphorus. It is important to use laxatives sparingly and only as directed by a healthcare professional.

Laxative abuse can lead to laxative dependency, where higher doses are required to stimulate bowel movements
Laxative abuse can lead to laxative dependency, where the body relies on these agents for regular bowel movements. Over time, the colon may stop reacting to the usual laxative dose, requiring larger doses to produce bowel movements. This can create a cycle of misuse.
Laxative abuse is often associated with people who have body dysmorphia or eating disorders such as anorexia nervosa and bulimia nervosa. Laxative use is not only related to vanity but can become a progressively unhealthy way of dealing with feelings of shame, depression, the need for acceptance, the need for control, or anxiety.
Laxative abuse can also lead to serious negative health consequences, including death. The chronic use of laxatives can cause severe dehydration, a reduction in electrolytes, and a disturbance in mineral balance, such as magnesium, sodium, potassium, and phosphates. This can impair the function of vital organs and cause irreversible damage.
Other symptoms of laxative dependence include muscle spasms and cramps, urinary tract infections, intestinal paralysis, and an increased risk of colon cancer.

Laxatives can cause a thinning of the mucus that protects the gut lining, compromising the intestinal barrier
Laxatives can have a detrimental impact on the mucus that protects the gut lining, causing it to thin and compromising the intestinal barrier. This was observed in a study by researchers at Stanford University School of Medicine in California, who administered the laxative polyethylene glycol to mice for six days. The laxative caused short-term diarrhoea, but it also had long-term effects on the composition of the microbiome.
The mucus barrier was compromised during the study and became more permeable, though it did recover after the diarrhoea had passed. Parallel to this increased permeability, the mice experienced an increased immune response. This indicates that the immune system was activated in response to the laxatives.
It is well known that increased intestinal permeability can lead to low-grade chronic inflammation, a condition associated with inflammatory bowel disease, among other diseases. As such, long-term laxative abuse is likely to cause intestinal permeability and inflammation.
The thinning of the mucus that protects the gut lining is a serious concern, as it can lead to a compromised intestinal barrier, allowing unwanted substances to pass through. This can have far-reaching implications for gut health and overall well-being.
Furthermore, the study found that certain microbes flourished while the growth of others was hampered. A microbial family known as S24-7, which is exclusive to warm-blooded animals and helps to ferment carbohydrates, nearly became extinct. These microbes did not recover after the treatment period, though they could be reintroduced into the system. The mice were found to have less diverse gut bacteria overall, which is a problem because gut microbiome diversity is essential to bowel health. Reduced diversity can lead to issues like Crohn's disease.

Laxative abuse can increase the risk of developing colon cancer
A study on the association between laxative use and colorectal cancer risk found that individuals who reported using non-fiber-based laxatives regularly were at a significantly increased risk for colorectal cancer compared to those who reported no laxative use. The risk of colorectal cancer increased with non-fiber-based laxative use, while fiber-based laxative use was not associated with a significant change in risk.
Another study found that people who used non-fiber laxatives more than five times a year had a 43% increased risk of colon cancer compared to those who used them less than once a year. In contrast, people who used fiber-based laxatives at least four days a week for four years had a 56% lower chance of getting colon cancer than those who didn't use them.
The World Health Organization (WHO) has published monographs on the safety, efficacy, and quality control of some plants used in laxatives, recommending that products containing anthraquinone glycosides should not be used for longer than 1-2 weeks due to the possible incidence of serious adverse events, such as electrolyte imbalance. The European Medicines Agency (EMA) and the Federal Institute for Medicines and Medical Devices in Germany have also recommended not using anthraquinone laxatives for more than two weeks.
While the findings suggest an association between laxative use and colorectal cancer risk, more research is needed to determine the specific types of laxatives and their long-term use that may be associated with higher cancer risk.
