How does insulin work?


There are quite a few different types of insulin on the market and a whole bunch of brand new ones arriving soon.

The basic broad classification is long vs short acting. As their name implies they are long or short acting. What does that mean? When you require insulin you have both basal needs as well as prandial (meal time) needs. Your basic and ongoing metabolism needs glucose to go into the cells (all the cells in the whole body) on a minute to minute basis and hence a basal requirement of both glucose and insulin. Insulin is the key that gets the glucose in. When you eat carbohydrates you then require insulin to get the glucose load out of the blood circulation and into the cells where it can be used as fuel.

The long acting insulins cover basal requirements and act for a long time – 6 – 24 hours and some new long actings with a duration of about 48 hours.

The short acting insulins act for a short period of time, starting within about half an hour of injecting and then lasting for around 4 hours. There are brand new ultra short acting ones that are soon to arrive.

Insulin is a dangerous substance and the most acute danger is hypoglycaemia. In other words you inject too much insulin and the sugar plummets very low. At different levels for different people but generally below 2.5 mol/l you not only feel awful but can become unconscious and potentially no longer require a bucket list.

For this reason it is imperative that if you are injecting insulin you understand how it works, when it starts working, how long it works for, the shape of the curve of the action and also imperative to know what your number is – your blood glucose. Before injecting insulin you should ideally do a glucose test and factor this number into the equation.

It’s in the detail


Type 1 diabetes is a diagnosis that rocks most families and patients and affects the entire family dynamic for the rest of the patient’s life. It’s affect is minute to minute and second to second and quality of life is a very key thing that gets given a good shaking up – of all affected.

Have you ever had a drop in sugar? How did it make you feel? Can you imagine going from high to low like a rollercoaster most days? That is what some patient’s face. Hard for the patient, harder still for the parent/care-taker.

For some people the term “brittle” diabetes is a swear word and does not exist, for some people it is an excuse to run their sugars all over the show. For me the truth is somewhere inbetween.

Certainly in my experience there are definitley patients who are more sensitive to insulin and in tiny alliqots than other patients, especially children, women at different times of cycle/states of hormones etc. It becomes incredibly tricky to get the “dosing” right on 4 injections a day. The more sensitive one is to insulin the easier I find it to manage patients on an insulin pump. This will enable smaller doses, a 1/3 less of a total daily dose and easier titrations in these sensitive candidates.

Life after diagnosis is tricky and quality is key. Every minute and every second counts towards that. A roller coaster is no way to live. Rather a smoothie – nice even sugars, minimal variation and mostly at target makes for a happy patient.insulin pump

A 2 % drop in A1c with just one addition – I call it a “smoothie”


Recently I have started quite a few patients on dexcom and to my and their delight with this simple intervention we have achieved a 2 % drop in A1c – WITH obliteration of hypos over a 2w to one month period. Previously unheard of!

For a type 1 diabetic who has long battled with both low sugars and high averages – neither good in long or short term it is a great joy to see the “smoothing” out of a very detailed download (c/o dexcom).

Yipee Yay!!dexdowndex sensor

Mountain splendour splendour


For our 5th wedding anniversary we galavanted to Mountain Splendour – a wonderful place in the Drakensberg mountains where one can “glamp”. Glamping is a wonderful way to camp with children. Ours are 2 and 4. The tent is set up for you with all you need, including electric blankets ! What bliss and shear luxury.

The setting is arguably one of the most breathtaking in terms of mountain splendour. Surrounded by natural beauty with mountain biking/running trails to your heart’s content. For the children there is a playground that rivels the best of them full of wonderful swings, clambering things and even a caravan to play in. My children would have slept in the playground if we had let them. Possibly the only drawback being that they just wanted to be there all the time!

We had a wonderful time and will certainly be back.

Mountain splendour, splendour!

Mountain splendour, splendour!

Scrambled egg for breakfast


The pendulum doth swing from one end to the other. At the moment eggs are in. What is a good start to the day? Especially if you are not wanting to have a carb “excursion” it bodes well to have a protein start to the day. Breakfast is a very important meal, perhaps the most important and affects metabolism for the rest of the day. There are studies that link skipping breakfast to the development of type 2 diabetes. Other studies that link general good health to eating a good healthy breakfast.

There is so much rubbish out there for breakfast including just about all the cereals on the market though some are worse than others. They are jam-packed full of sugar.

Not everyone is happy to have eggs for breakfast – there are some other options : jogurt (no sugar added kind), fish (though if not keen on eggs less likely to be keen on fish I think) and then there is a whole range of future life breakfast that needs to be dosed in the correct portion and I would suggest the no sugar added one.

But back to scrambled eggs – easy to do, easy to flavour with just about anything from a touch of salt to cheese or even more adventurous toppings. If you are diabetic and you have protein for breakfast – it is “free” and does not require a dose of insulin. Bargain.scrambled eggs
