01 – My diagnosis with diabetes-1 changed my lifestyle

In this blog I will take you to the specific period of my life being diagnosed with diabetes at the age of 15. Today, after approximately 35 years, I still vividly remember certain details. Funny enough, one of the first things is that the tennis tournament at Roland Garros’ was ongoing and that I was watching the finals from the hospital bed: Mats Wilander, the Swede, beat Guillermo Vilas, the Argentinian predecessor of the Spanish Rafael Nadal. Vilas’ dedication – he trained 6 hours per day on average, and it was fascinating to observe that, being a lefty, his left arm was twice as thick as his right one.

I don’t know if this is a tell of how the lifestyle change has been communicated to me, but apparently, I have digested the diagnosis and proceeded with the important things in life – likely, tennis was one of these at my age of 15.

What were the indicators of diabetes?

Going back in time I can actually experience the taste of bitter lemon, the soda. Thirst and the urgency to go to the loo. At the same time. And a lot and often. Like most 15-year olds, I lived with my parent, together with brothers and sister. We had a lavatory that I frequented on the ground floor, next to the storage closet with bottles of soda. At night, and sometimes several times, I would jump out of bed, go down to get a bottle of bitter lemon. I would sit down on the loo and urinate, while drinking from the bottle. Hell was I thirsty!

Second signal: “what about some more exercise?” well-intended remarks from parents and brothers looking at my body that, despite a reasonably sporty life, looked kind of skinny. My elder brothers were already using some kind of fitness instruments, like hand and chest muscle exercisers, and I was given an arm-force-controller to strengthen my muscles.
Still, I kept losing weight which dropped to around 59 kg, which is not a lot for a 15-year-old with a height of 6’4. The so-called body-mass-index (BMI) of 15.7 (weight divided by (height times height) in kg/sq meter indeed suggested underweight.
A visit to the general practitioner was quickly made, and a blood test revealed an elevated level of glucose in my blood. An appointment was made with a befriended internist and from that moment on I was officially announced diabetic.
I was hospitalized for a week, receiving lots of information. Practicing injecting, using syringes on oranges, blood sampling for all kind of tests, and of course fingerpricks to measure blood glucose; these were the eighties and at that time still triangulated lancets were used, which were actually cutting your skin and hurt really badly. To the eye doctor, to the dietician, and to other doctors I do no longer see to remember. Every time I was told the same story, that the absence of insulin not only prevented the uptake of sugar by the cells of the body (and consequently the generation of energy for proper functioning of cells and the body), it would in the long run have all kind of nasty effects on the heart and vascular system. Nice to hear. Not! Especially not for my parents. As a 15-year-old I did not care much. An adolescent, having arrived at puberty, typically does not look ahead much further than a few hours. All the attention, initially, was not all too bad.

But then you also get a lot of attention that, as an adolescent, you really could do without. Everyone seems to know someone diabetes. My teacher French said that she had an uncle who lived with diabetes to become 90: “so you can grow old having this disease”. As if I had any concerns about old age at that time. Or horror stories about amputations, caused by poor blood vessels. Or my first visit to the Dutch Society Diabetes (DVN): I am sure well-intended advice has been given, but I remember coming home that I said that every was wearing glasses, with thick glasses like jam jars.
Me, I thought it was all very simple: same life as before, just stay away from sweets, count your carbs, and inject the missing protein (insulin). Other than that, keep doing like before, in and outside of school. To my environment I was undergoing an enormous lifestyle change. For me, I was not really aware and continued to be a happy adolescent having reached puberty.

Change-management plan

In my professional life I have been subject to and have organised several changes, for instance to improve processes, to replace certain internal positions by external ones, to start using new procedures, and so on. Beforehand, a detailed communication and implementation plan is made. The reason for the change and the implications for the organisation and the individual. The latter can be a hot topic for those affected by the change, and the supervisor can take away some of the tension by saying it is okay to be afraid of the upcoming change. That the change beside advantages can potentially have some negative aspects as well. Or provide examples of how other companies or persons have dealt with similar changes.

I doubt it, that at my diabetes diagnosis a detailed change management plan was in place.
I find it interesting now, in hindsight, to think about it; about the advantages and disadvantages of the disease, for instance. The major disadvantage, of course, that the body is no longer capable of producing insulin and that, in case your cells and organs want to keep on functioning, you need to daily self-inject the protein. With 35 years’ diabetes experience I also see the advantages that coincide with this lifestyle change: a focus on healthy living, having my blood glucose values as reminders: regular and proper food low in sugar and fat, regular exercise.

I will tell you more about this in my next blog.




“you only know that you miss it when it’s gone” is an appropriate saying considering diabetes, missing insulin. In case your body does not produce insulin, your diabetes is called diabetes (mellitus) type 1; in case your cells have become insensitive to the insulin your body produces then your diabetes is called diabetes type 2.
Insulin is a hormone produced by the pancreas and secreted into the blood (by a group of cells belonging to the pancreas (islets of Langerhans)). Hormones are signal compounds/proteins that reach the target cells in the body via the bloodstream.
Your cells need to take up sugar as fuel. Without it no energy is produced, and cells will fail to grow or function. Normally insulin is being secreted in case of a rise in blood glucose levels – this because of mono-saccharides (glucose) that have entered the blood for example after drinking soda; a sandwich contains poly-saccharides (carbohydrates) that are being degraded into mono-saccharides first before entering the bloodstream and giving rise in blood glucose level. When the pancreas secretes insulin into the blood it stimulates the uptake of sugar (glucose) by the cells from the blood and inhibits the breakdown of fat and polysaccharides.
When you are not diabetic then your glucose levels are stable around 5 mmnl/l or 90 mg/ml. In case insulin is not around the glucose levels in the blood go up, the cells in your body will no longer take up glucose to produce energy, breakdown of fat and glycogen is no longer inhibited. You will get tired as a consequence; also, you will drink more and secrete more urine, because of the kidneys’ efforts to get rid of the surplus of glucose from the blood. Your body cries out for energy and start burning what is available, starting with fat, with muscle mass next. You will start losing weight.

Of all countries I have lived in the glucose levels are expressed in mmol/l in the Netherlands and Eastern-Germany; the unit mg/ml is used in the USA, Western-Germany and Austria. Glucose is a mono-saccharide consisting of 6 carbon atoms, 12 hydrogen and 6 oxygen atoms (C6H12O6). 1 mol glucose has a weight of 180 grams, with a mol being a huge number often used to indicate the quantity of a compound; in analogy to a dozen (being 12 pieces) a mol indicates 6,022 14 × 1023 particles/molecules. A millimole, mmol, is one thousandth of a mol (10−3 mol).
It may suffice to remember that 1 mmol/l glucose equals 18 mg/ml glucose; the norm value of 5 mmol/l therefore equals 90 mg/ml.
