Constipation is a common problem that many people experience at some point in their lives. It can happen when a person does not eat enough fiber, does not drink enough water, or does not move their body regularly.
For many people, the first step to solve constipation is to change their diet or lifestyle. However, when these simple changes do not work, people often turn to medicines called laxatives. These products are easy to find in pharmacies and are widely used around the world.
While laxatives can be helpful in the short term, a new study suggests that using them regularly over a long period of time may be linked to a higher risk of developing dementia.
Dementia is a condition that affects memory, thinking, and daily functioning, and it becomes more common as people age. Because dementia has no cure and can greatly affect quality of life, scientists are very interested in understanding its possible causes and risk factors.
The research was carried out by scientists from the Chinese Academy of Sciences and was published using data from the UK Biobank, one of the largest health databases in the world.
The UK Biobank has collected health information from more than 500,000 people in the United Kingdom. This includes details about their lifestyle, medical history, and long-term health outcomes. Such a large dataset allows researchers to look for patterns that might not be obvious in smaller studies.
In this study, the researchers focused on 502,229 people who did not have dementia at the beginning of the research. Among these participants, about 3.6 percent reported that they used over-the-counter laxatives regularly. This means they took these medicines on most days during the month before they joined the study.
The researchers followed these people for about 10 years. During this time, they recorded how many participants developed dementia. They found that 1.3 percent of people who used laxatives regularly were later diagnosed with dementia.
In comparison, only 0.4 percent of people who did not use laxatives regularly developed the condition. After taking into account other factors such as age, overall health, and lifestyle, the researchers found that regular users of laxatives had a 51 percent higher risk of developing dementia.
The study also looked at different types of laxatives. One type, called osmotic laxatives, showed the strongest link. These laxatives work by drawing water into the bowel to make stool softer and easier to pass. Although all types of laxatives were included in the study, osmotic ones appeared to be more strongly connected to the increased risk.
It is very important to understand that this study does not prove that laxatives cause dementia. It only shows that there is a connection between the two. There may be other reasons why people who use laxatives often have a higher risk.
For example, people who need laxatives regularly might already have other health problems that affect both their gut and their brain. Scientists call this type of finding an “association,” not a direct cause.
Even so, the results are strong enough to raise questions and encourage further research. The researchers believe that one possible explanation involves the close relationship between the gut and the brain.
This connection is sometimes called the “gut-brain axis.” Inside our intestines live trillions of tiny organisms, known as the gut microbiome. These bacteria help digest food, support the immune system, and may even influence how the brain works.
Using laxatives often could disturb this delicate system. It may reduce the variety of helpful bacteria in the gut or change how signals are sent between the gut and the brain. Over time, these changes might affect memory and thinking abilities. However, more studies are needed to fully understand how this process works.
Because dementia develops slowly over many years, it is important to take steps early to protect brain health. Simple habits can make a difference. Staying mentally active by reading, learning new skills, or talking with others can help keep the brain engaged.
Regular physical activity improves blood flow and supports overall health. Eating a balanced diet with fruits, vegetables, whole grains, and healthy fats can also benefit both the gut and the brain.
Good sleep is another key factor, as the brain needs time to rest and recover. Managing long-term conditions such as diabetes and high blood pressure is also important. Avoiding smoking and limiting alcohol can further reduce risk. Managing stress is helpful too, since long-term stress can affect both the body and the mind.
This study offers an important reminder that even common medicines may have effects that are not fully understood. While laxatives are useful when needed, using them regularly without medical advice may not be the best approach.
People who often rely on these products should consider speaking with a doctor to find safer and more lasting solutions for constipation.
In the end, taking care of both gut health and brain health is important for long-term well-being. Small daily choices, such as eating well, staying active, and using medicines wisely, can help support a healthier future.
