Many people around the world live with high blood pressure, a condition that quietly increases the risk of serious health problems like heart attacks and strokes.
At the same time, another condition called diverticulosis affects the digestive system, especially in older adults. Although these two health issues may seem unrelated, new research suggests there could be a surprising connection between them.
Diverticulosis happens when small pouch-like bumps form in the wall of the intestine. The intestine is a long tube in the body that helps break down food and absorb nutrients.
These small pouches are usually harmless at first, but in some people, they can lead to pain, infection, or other complications. The condition becomes more common as people age, and it is often linked to changes in how the gut moves food along.
High blood pressure, also known as hypertension, is very common and affects millions of people worldwide. It often develops slowly and may not cause obvious symptoms, but over time it can damage the heart and blood vessels.
To manage this condition, doctors usually recommend healthy lifestyle changes, such as eating well and exercising, along with medications.
There are several types of medicines used to lower blood pressure. Among the most widely used are ACE inhibitors, beta-blockers, and calcium channel blockers.
These medicines work in different ways, but they all help relax blood vessels and reduce pressure on the heart. While these drugs have been used for many years and are generally safe, scientists are still learning about their full effects on the body.
A team of researchers from Imperial College London decided to study these medicines more closely. They wanted to understand not only how these drugs lower blood pressure, but also whether they might have other effects that are not yet fully understood.
To do this, they used a scientific approach called genetic analysis. This method involves studying DNA and other biological information to see how certain factors in the body are linked to health conditions.
The researchers first identified the specific proteins in the body that these blood pressure medicines act on. Proteins are important parts of cells that help carry out many functions in the body.
After identifying these targets, the scientists examined genetic data from around 750,000 people. This large amount of data allowed them to look for patterns and connections between these proteins and different health conditions.
They also used data from the UK Biobank, which is a large research project that collects health information from hundreds of thousands of people in the United Kingdom. By combining genetic data with health records, the researchers were able to explore possible links between blood pressure medicines and other diseases.
What they found was unexpected. One type of calcium channel blocker appeared to be linked to a higher risk of developing diverticulosis. This was surprising because these medicines are mainly designed to affect the heart and blood vessels, not the digestive system.
The researchers believe this link may be explained by how the medicine affects muscle movement in the gut. The intestine relies on smooth muscle contractions to move food through the digestive system.
If these muscles do not work as well, food may move more slowly, which could increase pressure inside the intestine and lead to the formation of small pouches.
Even though this finding is important, the researchers strongly emphasized that people should not stop taking their blood pressure medication because of it. Managing high blood pressure is very important, and the benefits of these medicines are well proven. The possible increased risk of diverticulosis does not outweigh the need to control blood pressure.
The scientists also noted that their results do not mean doctors need to change how they prescribe these medications at this time. Instead, the findings provide useful information that can guide future research. If patients have concerns, they should always speak with their doctor before making any changes to their treatment.
This study was led by Dr. Dipender Gill and was published in the journal Circulation. It adds to our understanding of how commonly used medicines can have effects beyond their main purpose. In the future, this knowledge may help doctors choose treatments that support both heart health and digestive health.
If you care about high blood pressure, please read studies that early time-restricted eating could help improve blood pressure, and natural coconut sugar could help reduce blood pressure and artery stiffness.
For more health information, please see recent studies about added sugar in your diet linked to higher blood pressure, and results showing vitamin D could improve blood pressure in people with diabetes.
