Keep taking your BP tablets

Many people only take blood pressure medication when they’re under stress and worry about side effects, risking their long-term health.

If you’ve been prescribed medication to lower your blood pressure, do you take it every day? You’re not alone if you don’t, say researchers from King’s College London who analysed data from 53 different studies relating to patients’ adherence to treatment for raised blood pressure. Study participants had uncomplicated hypertension – those with diabetes or cardiovascular disease were not included.

Their evidence suggests that most people have no real understanding of their health problems and implies that doctors need to explain the causes and symptoms and actively discuss side effects so that any fears can be allayed.

A doctor may know why and how a certain medication will help prevent disease or symptoms but unless a patient fully understands what they’re prescribed they’re far less likely to stick to the treatment. And when they don’t take their medication correctly, the risk of adverse effects or disease rises.

GPs usually advise patients on lifestyle changes they can make to lower their blood pressure and often prescribe medication such as an ACE-inhibitor as well.


Yet the researchers found that patients’ understanding of what causes hypertension was often woolly and sometimes incorrect, which led them to make bad choices when it came to taking their medication.

Participants reported assessing their own blood pressure levels based on how stressed they felt or on symptoms they associated with hypertension. While stress can be a factor for hypertension it hasn’t been found to be an important element. Some patients also avoided taking pills because they were worried about potential adverse side effects or because they wanted to avoid becoming addicted to the medication.

Soft drinks and long term health

Sugary drinks can cause weight gain and long-term health problems if drunk regularly for as little as a month, according to scientists.

Too much fizzy pop or sweetened fruit juice alters the body’s metabolism, so that the muscles use sugar for energy, instead of burning fat, a study found.

The effect is long-term, making the pounds harder to shift and raising blood sugar levels, which increases the risk of conditions such as type 2 diabetes, it was claimed.

Dr Hans-Peter Kubis, who led the research at Bangor University, said: “Our results give a stark warning against regularly drinking sugar-sweetened drinks.”

He added: “Not only can regular sugar intake acutely change our body metabolism; in fact it seems that our muscles are able to sense the sugars and make our metabolism more inefficient, not only in the present but in the future as well.

“This will lead a reduced ability to burn fat and to fat gain. Moreover, it will make it more difficult for our body to cope with rises in blood sugar.”

Dr Kubis said that, when in need of refreshment, people should drink water instead.

His researchers found that the muscle cells of volunteers both identified and responded to a sugary diet, switching how they used the fuel. This created an inefficient metabolism in lightly active men and women who drank fizzy beverages on a regular basis for four weeks.

Dr Kubis added: “What is clear is our body adjusts to regular soft drink consumption and prepares itself for the future diet by changing muscle metabolism via altered gene activity, encouraging unhealthy adaptations similar to those seen in people with obesity problems and type 2 diabetes.”


In the study, 11 people in their twenties supplemented their diets with sugary soft drinks for a month. Before and after the study they had their blood and muscle tissue, as well as their whole body metabolism and composition, tested.

Genes and proteins important for fat and sugar metabolism were analysed and blood sugar and fats assessed.

Dr Kubis said: “What we found is that it is not the sugar in itself that puts on weight but the way it gets the body to store more.

“This would relate to all kinds of soft drinks with a high sugar content, including fruit juices.

“It was a small study because it is difficult to find young people who have not previously been exposed to a lot of soft drinks and who are willing to undergo muscle biopsies.

“But we are now hoping to carry out a bigger study with more participants over a longer period of time.”

Dr Kubis has been campaigning for the Government to take action to encourage the public to cut down on sugary drinks.

He added: “Clearly taxation on sugary drinks is overdue. This money could be invested in the NHS where it is urgently needed to treat people with obesity problems and diabetes.”
