RCGP: What doctors need to know about types one and two diabetes in young people

The Royal College of General Practitioners have recently released an educational programme for UK doctors which they have very kindly allowed me to link to our website.

I recorded this over a year ago and I think the college held off production until their type two diabetes low carb course was also released for doctors.

This means that the RCGP joins the American Association of Clinical Endocrinologists as supporters of low carbing  for both type one and two diabetes.  Surely the other clinical associations and Royal Colleges will follow in due course?

The screencast includes information on diagnosis, emergency situations, blood sugar and dietary management and contraception.

“I have also separately produced an educational screencast on Diabetes in adults (type 1), children and young people (type 1&2) for the Royal College of General Practitioners in my role as an RCGP Clinical Adviser”

Public Health Collaboration Conference 2018: a great success for Lifestyle Medicine

I was delighted to attend and speak at the third PHC conference in London this year.  We met at the Royal College of General Practitioners in London on the sweltering weekend of the Royal Wedding. Apart from superb international speakers we were treated to low carb, high protein food, such as one would typically eat on a ketogenic diet. Instead of picking at our dinners as we often have to do with mass catering  we could eat the whole lot. Great!

Dr Peter Brukner from Australia started off the weekend with a review of what was happening in the low carb world. There are more and more reports coming out describing the advantages of ketogenic and low carb diets to different groups of people but the establishment are fighting back viciously as can be seen by the attack on Professor Tim Noakes in South Africa.  Indeed if his defence lawyers and expert witnesses had not worked for free he would be bankrupt.  This is a terrible way to wage war on doctors who are acting in the best interests of their patients.

Dr Aseem Malhotra also described bullying tactics that had been used against him when he was a junior doctor and first becoming publicly engaged in the low carb debate. I have been subjected to this as well.  Professor Iain Broom showed that the proof that low carb diets are superior to low fat diets goes back 40 years.

Dr Zoe Harcombe gave us an explanation of how the calories in- calories out idea just doesn’t add up. The well known formulas about how many calories you need to avoid to lose weight don’t work in practice because of the complex compensatory mechanisms we have to avoid death from starvation.  How you put this over to patients and give them useful strategies for weight loss and blood sugar control was explored by Dr Trudi Deakin.

Food addiction is a real issue, at least it is for the majority of the audience in attendance, who answered the sort of questions usually posed by psychiatrists when they are evaluating drug addiction.  Unlike drugs, food can’t entirely be avoided but ketogenic diets are one tool that can be used to break  unhealthy food dependence. This worked for presenter Dr Jen Unwin who at one point had a really big thing for Caramac bars.  I haven’t seen these in years but they did have a unique taste.

Dr David Unwin showed clearly that fatty liver is easily treatable with a low carb diet.

Dr Joanne McCormick describes how her fortnightly patient group meetings are making change accessible for her patients and how many GPs in the audience could broach the subject in a ten minute consultation.

The website Diabetes.co.uk will shortly be starting up a type one educational programme online that all are welcome to join. I discussed the issue of what blood sugar targets are suitable for different people and how they can achieve this with dietary and insulin adjustment.

Dr David Cavan spoke about reversing diabetes in patients in Bermuda. Although Bermuda looks idyllic the reality is that good quality food is about five times as expensive in the UK as it is all shipped in. Many inhabitants work their socks off but barely cover their costs and cheap sugared drinks and buns are their staple diet. Despite these setbacks he managed to persuade a lot of diabetic patients to ditch the carbs and this had favourable results even after the educational programme had stopped.

A cardiologist Dr Scott Murray described the effects of metabolic syndrome on the heart and really why sticking stents in diseased arteries is too little, too late. He is convinced dietary change is needed to reverse and prevent heart disease. This is the first time I have been told that certain types of heart failure and atrial fibrillation are direct effects of metabolic syndrome on the heart.

The importance of exercise for physical and mental well being was not neglected and we had Dr Zoe Williams describing the great benefits that even the minimum recommended exercise can produce.

Dr Simon Tobin and Tom Williams spoke enthusiastically about Parkrun. This is a free event that runs every Saturday morning in parks all over the world. You can choose to walk, jog or run the course.

Claire McDonnell-Liu is the mother of two children who have greatly benefited from a ketogenic diet. The conditions are urticaria and epilepsy.  Although NHS dieticians do help families with childhood epilepsy who want to use a ketogenic diet, they can’t do it unless drugs have failed, as this is NICE guidance. I wonder how many children would benefit in fit reduction without side effects of drugs if this guidance was changed?

This was a fabulous conference with a positive enthusiastic vibrancy. Thanks to Sam Feltham for organising this event especially since he has become a new dad as well.

The Public Health Collaboration are putting all the talks on You Tube.

I was interviewed about diabetes and women’s health issues for Diabetes.co.uk and Diet Doctor and these interviews and many others will be available for you all to see to improve your lives with diabetes.

 

 

 

How does blood sugar control compare between pump users and insulin injecting adults?

insulin pump

If adults get the same level of education about blood sugar management there is only a tiny improvement in blood sugar control with a pump compared to a basal bolus injection regime.

The REPOSE trial was based in the UK with 315 participants across eight sites. Using small groups the patients were taught the DAFNE course, Dose Adjustment for Normal Eating. After the course the patients were randomised to either multiple daily injections which is standard UK management, or insulin pump use.

The organisers wanted to see how many people managed to get their hba1c below 7.5% after two years and what effects the regimes had on quality of life and hypoglycaemia.

Out of the original 315 patients, 260 finished the courses and entered the trial. There were small improvements in both groups for hba1c. The pump group got a 0.85% improvement in hba1c and the injectors got 0.42% improvement. This was not considered to be good enough to recommend pump provision, which is more expensive than pen injectors, to adults as a routine measure.

The pump group started with hba1s averaging around 9.5% and ended up around 8.7%. The injectors started with an average of 9.0% and ended up around 8.5%.  In addition there was no particular difference in hypoglycaemia or psychosocial outcomes.

My comment: It is a pity that DAFNE is considered the gold standard educational tool for type one diabetics when the outcomes are so underwhelming. The main problems are that although carb counting is included, carbohydrate restriction is not.  Insulin coverage of protein is not done and the seven unit rule is ignored. These are the main reasons that the outcomes are so poor. Structured education in person is expensive and time consuming for health care professionals. Why not grasp the nettle and actually teach people what they need to know to get normal blood sugars and not hba1cs of 8.5-8.7 which are certain to lead to diabetic complications?

Learning and Diabetes: A vicious circle

Learning and Diabetes

Rowan Hillsoncalculator

Practical Diabetes Nov/Dec 16

Only 32% of type one diabetics and 78% of type two diabetics are currently offered structural education in England. Even then, not all will attend. Will it have any positive long term effects for those who do? Many issues affect learning. This article discusses some of them.

Literacy and numeracy

In England in 2011, 15% of the population aged 16-65 had the learning that is expected of an eleven year old child. This is considered “functionally illiterate” by the National Literacy Trust.  Although they would not be able to pass an English GCE, they can read simple texts on familiar topics. More than 50,000 UK diabetics are at this basic level of reading ability.

Numeracy problems are higher with 24% of adults function at the same level as your average eleven year old. Testing diabetics shows that numeracy and literacy are linked and that blood sugar control is better in those with better numeracy and literacy. This is not surprising since so many tasks need these skills.

Weighing foods and estimating portion sizes

Addition

Converting between metric and imperial systems

Multiplying and dividing

Using decimals

Recognising and understanding fractions

Working with ratios, proportions and percentages

Readability

Arial 12 point font, upper and lower case, on white or off white backgrounds, using short words, short sentences and short paragraphs all improve readability.

Health Literacy

Health literacy includes reading, writing, numeracy, listening, speaking and understanding.

In the type two diabetes population, lower health literacy was significantly associated with less knowledge of diabetes, poorer glucose self- management, less exercise and more smoking.

In the USA people understood food labels better if they had higher income and education.  Overall 31% gave the wrong answer to food label questions. Many diabetics have problems with misinterpreting glucose meter readings, miscalculating carbohydrate intake and medication doses.

Lower scores were associated with being older, non-white, fewer years in education, lower income and lower literacy and numeracy scores.

When an internet based patient system was offered, those with limited health literacy were less likely to sign in and had more difficulty navigating the system.

Cognitive impairment

Alzheimer’s disease, vascular dementia and other cognitive impairments are more likely in diabetics particularly those with type two diabetes. A longer duration of diabetes and a younger age of onset were associated with cognitive impairment.

Hyperglycaemia

High blood sugars can cause poor concentration, tension, irritability, restlessness and agitation. In experiments, high blood sugar induced delayed information processing, poorer working memory, and impaired attention.

In five to eighteen year olds with new type one diabetes most neuropsychological tests showed considerable impairment.  One year post diagnosis, dominant hand reaction time was worse in those with poor glycaemic control.

Long term, type ones diagnosed before the age of 18 had five times the risk of cognitive impairment compared to their non- diabetic counterparts. Chronic hyperglycaemia increased the risk.

Hypoglycaemia

Most friends and relatives can recognise if someone well known to them has a low blood sugar, often faster than the individual. Cognitive performance drops at blood sugars of 2.6-3 in non- diabetic subjects.  In type one children, those who had recurrent severe hypoglycaemia had more impaired memory and learning.

Psychological issues

Both depression and anxiety can impair test performance. Both of these and other mental illnesses are more common in diabetics.

Sensory and motor problems

Visual impairment and deafness can make some learning methods difficult.

Conclusion

We all learn in different ways. A substantial proportion of the population has low literacy and numeracy. This impairs health literacy which impairs diabetes knowledge for self -care. Poor numeracy may worsen blood sugar control. Clearly written, easily readable information helps everyone. Having diabetes increases the risk of cognitive impairment both at diagnosis and long term. Both high and low blood sugars affect current ability to learn and may have long term adverse effects on cognition.

Before teaching diabetics it is worth having a think about any difficulties your patient could be having assimilating the learning. If so, how can you tailor your teaching to their needs?
