Dr Briffa's Blog - A Good Look at Good Health
A health-focused blog that makes sense of science, and offers accurate, trustworthy and practical advice about all aspects of healthy living.
Cardiovascular diseases (such as heart disease and cerebrovascular disease which can give rise to heart attack and stroke respectively) represent the most common cause of death in Western countries. Not surprisingly, health agencies and the medical profession focus on them a lot. In recent years, there has been a vogue for assessing cardiovascular disease risk [...]
Epidemiology is a branch of research which analyses data to look for associations between things. This brand of research will very often throw up ‘facts’ like ‘red wine lowers risk of heart disease’, because of evidence that red wine drinkers are at reduced risk of heart disease. However, epidemiological evidence can never tell us if [...]
Previous research has found a link between lower levels of vitamin D and higher body weight, causing some to speculate that vitamin D deficiency may be a factor in obesity. The problem with this sort of evidence is that while it can show a link between vitamin D deficiency and, say, obesity, we can’t tell [...]
Diverticular disease is a condition characterised by the presence of small out-pocketings in the wall of the large bowel. The condition is common in the western World, and is usually symptomless. However, if one or more of the pockets becomes inflamed or infected, symptoms such as diarrhoea, pain, abdominal bloating and the passing of blood [...]
Reading the British Medical Journal today I saw an item in the ‘news’ section which caught my eye. Entitled ‘Too frequent use of painkillers can cause rather than cure headaches’, it relays information coming from the National Institute of Health and Clinical Excellence (NICE) in the UK. It seems that in some cases, painkilling medication [...]
A lot of conventional medicine is about symptom suppression. For example, with someone with ‘cramping’ in the gut we may give a drug to reduce the cramping. A better (I think) though more alternative approach would be to attempt to find out what’s causing the cramping and sort that out. As an aside, cramping in [...]
Back in June I dedicated a post to the effectiveness of blood pressure medication. It was triggered by the fact that there’s abundant data to suggest that cholesterol-lowering ‘statin’ medication is really very ineffective. And by that I mean that the vast majority of people who take statins will not benefit. I wondered whether the [...]
The British Heart Foundation (BHF) is the UK’s largest and best-known ‘heart’ charity and, on the surface at least, appears devoted to doing what it can to reduce the burden of ‘cardiovascular’ issues such as heart attacks and strokes. The BHF website offers a number of stories of people which appear to highlight pertinent issues [...]
Why do doctors insist of checking cholesterol levels and blood pressure in their patients? At least part of the rationale is that these measurements will help identify individuals at heightened risk of things like heart disease and death, and appropriate steps might then be taken to reduce their risk. The value of ‘traditional risk factors’ [...]
Some of you may have noticed that I have, more than once, written about just how ineffective cholesterol-reducing drugs (including statins) are for preventing heart attacks and stroke and saving lives. Taken over several years, the data show that the vast majority of people who take them will simply not benefit from them (and have [...]
