In a recent study published in Circulation, researchers found that a type of blood pressure-lowering medication, called a calcium-channel blocker, may be linked to a higher risk of a type of bowel condition called diverticulosis.

This condition causes small bulges or pouches to appear in the lining of the intestine.

This gut problem particularly affects the elderly (as many as 65% of over 85s may be affected), and it can in some cases lead to a medical emergency if the pouches become infected or burst.

The research is from Imperial College London. One author is Dr. Dipender Gill.

In the study, the team examined the effectiveness and side effects of three common blood pressure medications: ACE-inhibitors, beta-blockers, and calcium channel blockers.

High blood pressure affects one in ten adults across the globe and increases the risk of heart attack and stroke.

The most common treatments for high blood pressure are lifestyle changes and medications.

However, despite the three main medications being taken by millions, testing their potential side effects (as well as studying their effectiveness for treating other diseases), can be difficult and often involves lengthy and expensive clinical trials.

To overcome this problem, the team used genetic analyses to study the effects of the drugs.

By checking versions of genes that mimic the effects of these drugs, the team was able to study the drugs’ effectiveness — and their potential side effects.

First, identified the proteins targeted by the drugs, and which help lower blood pressure.

Next, they analyzed genetic data from around 750,000 people and identified the so-called genetic variants that code for these proteins.

The team then studied whether these gene variants — which cause increased production of these proteins — were linked to an increased or decreased risk of other diseases.

The good news was that, as expected, these so-called genetic variants (which coded for proteins involved in lowering blood pressure) were linked to lower heart disease and stroke risk.

However, after assessing the risk of around 900 different diseases, the team found that the versions of genes related to the effects of a particular type of calcium channel blocker — the non-dihydropyridine class, were linked to an increased risk of a bowel condition called diverticulosis.

The team compared their findings with further genetic data and supported the potential link with an increased risk of the bowel condition.

This is the first time that this class of blood pressure drug has been linked to diverticulosis.

The team says it may relate to effects on the function of intestine muscles, which perform contractions to transport food through the gut.

This is nothing new, all these medications we take for various issues do their job for the most part, but all of the side effects are the problem. The bottom line is money, it's a domino effect, you take this pill for this problem, and then take this pill for this side effect, and take another pill for that side effect, and the Pharmaceutical Companies make millions and millions.

I just wonder if there's cures out there but they keep it under raps so they can continue to make billions on this meds that will curve your medical problem

I love it when they tell the story but give you absolutely no information. Like, what are the names of the drugs that were shown to cause the gut condition? Are there other choices we should talk to our doctor's about? What are the signs of the condition? Is the condition going to go away if you change meds?
