Many people around the world take medicine every day to control high blood pressure. This condition is very common and can lead to serious problems like heart attacks and strokes if not treated properly.
To manage it, people often eat healthier, exercise more, and take medications. These medicines help lower blood pressure and protect the heart.
At the same time, there is another condition called diverticulosis that affects the digestive system. This happens when small pouch-like bumps form in the lining of the intestine, which is the long tube that helps us digest food. These bumps are usually harmless, but sometimes they can cause pain, infection, or other issues—especially in older adults.
Recently, scientists from Imperial College London wanted to know if there was a link between these two common health problems. They studied how medicines for high blood pressure might affect the gut.
In particular, they looked at three popular types of blood pressure drugs: ACE inhibitors, beta-blockers, and calcium channel blockers. These medications have been used for many years, and millions of people take them safely. But the researchers wanted to know if they had any hidden effects on other parts of the body, like the gut.
To do this, the team used a method called genetic analysis. This means they looked at the DNA of about 750,000 people to understand how the proteins targeted by these drugs might be connected to other health problems.
They first identified which proteins the blood pressure drugs affect. Then they searched the genetic data to see if those proteins might also play a role in conditions like diverticulosis.
What they found was surprising. One type of calcium channel blocker—which helps relax blood vessels to lower blood pressure—was linked to a slightly higher risk of developing diverticulosis. The scientists think this might happen because calcium channel blockers could also relax the muscles in the gut.
These muscles are important because they help move food through the digestive system. If the muscles become too relaxed, it may slow down the movement of food and allow the small pouches of diverticulosis to form.
But there’s no need to panic. The researchers made it very clear that people should not stop taking their medication. Dr. Dipender Gill, who led the study, said that the benefits of blood pressure medicine are still much greater than any small risk of gut problems. These drugs save lives by preventing heart attacks and strokes.
This research, published in the journal Circulation, is part of a larger effort to better understand how common drugs affect our whole body. The goal isn’t to scare people, but to help doctors make even better choices in the future.
One day, this type of research could lead to more personalized treatment plans that give each patient the best results with the fewest side effects.
For now, the advice remains simple and important: keep taking your prescribed medicine unless your doctor tells you otherwise. High blood pressure is dangerous if left untreated, and these medications play a key role in keeping people healthy.
As science moves forward, discoveries like this will help improve how we treat diseases—not just in one part of the body, but everywhere. That means better health and longer lives for all of us.
