Hi All, I have just been diagnosed with type 1 diabetes. I am stunned and trying to figure out how best to manage this. I am worried about how to manage this at work and am keen to get safely back to exercise.
Hi Emma,
Nice to "meet" you!
This is a great place for the curious diabetic!....and it's free!
Keeping this as short as possible for you, here are just a few things I can think of that are worth keeping to the back your mind, which will hopefully be of help.
1. INSULIN TERMINOLOGY
"Basal" Insulin (e.g Levemir) and "Bolus" Insulin (e.g Novorapid).
Basal Insulin is often taken with an insulin pen, once (or twice) a day to keep background blood sugars ticking over steady. In theory, background blood sugar should be level (not rising or droppng) and the same 24hrs a day. The hospital will help you work this dose out.
Bolus Insulin is usually taken before each and every meal or snack to "use up" the carbs (and to an extent, proteins and fats too) from a meal. This is on a very individual need, again hospital (and you) will help you adjust this over time.
NOTE: By using a combination (trying to replicate the pancreas) of both basal insulin and bolus insulin each day, the aim is to keep blood sugars in range as much of the time as possible.
2. BLOOD SUGAR RANGE
"Ideally" blood sugar should remain between 4 and 10mmol each and every day. It's not always that easy, but will likely become easier to achieve with practice and time. The average of one's blood sugar is given by (typically) a 6 monthly or yearly blood test and is given as a HbA1c.
3. BLOOD SUGAR SPIKES
These can be a challenge to prevent and are best avoided if at all possible. These can often be avoided with careful timing of meal time (Bolus) insulin. Sometimes, particularly in the morning for me, I have to take my breakfast bolus insulin 20mins before I eat to avoid a spike up in blood sugar. Best to try and keep blood sugars in range.
4. INSULIN RATIOS AND INSULIN SENSITIVITY
Many T1's carb count and many diabetics find they are more insulin resistant upon waking. This usually means more insulin is needed for carbs in the morning than for carbs later in the day. For example, I will require more insulin for the same meal in the morning as I will for that same meal if eaten in the evening. My current ratios are 2 units of bolus insulin for every 10g worth of carbs upon waking (typically 8units for 40g of carbs at breakfast), 1.5 units of bolus insulin for every 10g of carbs at lunch and 1:10g for tea. Most ready made food has the carbs written on the label, harder to work out when eating out, but just practice and research.
5. DAWN PHENOMENON
Many diabetics get a rise in blood sugar upon waking (not every day; it can be random). I usually add in an extra unit of bolus insulin with my breakfast to help counteract this.
6. HYPO's
What some don't realise is, it can take more than one lot of glucose tablets or jelly babies to treat a hypo (low blood sugar (below 4mmol). One dose can usually work if the hypo has been brought on by sudden unplanned exercise, but if it's caused by too much insulin (over estimating bolus), it can take many more attempts to keep blood sugar within range. Generally, we are advised to wait 15mins after first intake of glucose before taking more glucose, need to check blood sugar regularly after a hypo.
7. EXERCISE
Heavy and moderate exercise usually affects insulin sensitivity. Insulin ratios and basal insulin doses can be affected for anything up to 48hrs, depending on the individuals response. Exercise and T1 need to be carefully managed, but nothing stops me from exercising, just got to take it slow and steady and build some experience using blood tests and adjustments.
8. FREESTYLE LIBRE
Absolutley fantastic. Finger prickless glucose monitor worn on the arm which gives 24hr readouts! Brilliant, fantastic, amazing, superb.
