What is the mechanism that causes Diabetic Fatigue?

I'm afraid I can't answer your question entirely but glucose control is one of the reasons for tiredness in diabetes.

If your sugar is high it affects the red blood cells ability to carry oxygen so you feel more tired.
If your blood sugar is low then it makes you tired as you have less fuel available to your body for the things it needs to do.
See http://www.diabetes.co.uk/tiredness-and-diabetes.html

I definitely feel more tired when my blood sugar is high or low. However I accept this isn't perhaps the only reason so I hope someone else on here has more info.

You've put that even people with diabetes for many years and good control have got complications. Have you considered that this is due to targets being too high and not tight enough control ?
Dr Richard Bernstein argues that diabetics are entitled to the same sugar levels as non-diabetics which avoids complications. However few of us are achieving tight enough control and are often being told our sugars are fine when they are not. For example my Hba1c has always been acceptable (not perfect but not worrying) yet I was getting huge swings in it (high and low readings all over the place) which was making me tired.

Like I said I hope someone else has more info for you as I'm very interested in the reasons behind tiredness too!

Hi .

Just an 'extra' thought to chime in here with .

Hypothyroidism can cause fatigue as it affects and slows down the bodies metabolism .
Energy source and drive is much slower with this condition .

Plus a few Diabetics can suffer with this condition as it is known to be linked .

I have it - and it does impact on your energy drive and levels .
Making them poor in supply - hence the need for thyroxine medication .

So diabetes 'plus' hypothyroidism can be a real reason or factor for low/poor energy levels .

Hope this can help .

It seems that there are a number of reasons but one of the problems is definition. This from Fatigue in Patients with Diabetes: A Review
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2905388/

*******************************
Results
Diabetes presents many potential pathways for fatigue, but focused studies on this symptom are rare. Furthermore, research on diabetes-related fatigue is limited by fatigue's non-specific symptoms and because fatigue researchers have yet to agree on standardized definition, measurement or diagnostic criteria. Additionally, few diabetes randomized clinical trials included measurement of patient-reported outcomes, such as symptoms or health-related quality of life in their study designs, though one that did provided some the meaningful finding that symptom-focused education improved self-management practices, HbA1c levels, quality of life and symptom distress.

Conclusion
There is a need to standardized definition, measurement and diagnostic criteria of fatigue in diabetes. We present a model that can guide focused studies on fatigue in diabetes. The model capitalizes on the multidimensional phenomena (physiological, psychological, and lifestyle) associated with fatigue in diabetes.

*******************************

One of the problems is that the fatigue may caused by things like lack of exercise, which also contributes to the onset of diabetes. Fatigue is a result of several physiological and psychological conditions, so there probably isn't a single answer but you should find the section Fatigue in Diabetes of interest.

Hi All .

Severe illness can also be the trigger to onset of Diabetes .

We have a very interesting thread that throws this up .
Will add it in here - when have tracked it down .
Here it is - viewtopic.php?f=19&t=34555
Fatigue symptoms are frequently mentioned in many of the posts in this thread .

No-one suffering or getting over severe illnesses is going to hit the gym and exercise - are they?
Fatigue can affect both body and the mind/spirit/focus .

I got diabetes immediately after pneumonia then battled off a septis infection.
Was told originally I was Type2 - till I pushed/insisted for further investigation into things .
They have told me since that I am more Latent - slow onset Type1 diabetic .

I am still learning more about this 'currently'
There is so much to learn and discover :eh:

Diabetes is a very complex and often confusing condition/disease .

Hope this can help .

I have mitochondria diabetes which is also known as maternally inherited diabetes and deafness (MIDD). It accounts for 1% of diabetics and is often mis-diagnosed as type 2 or even type 1.

Exhaustion, fatigue, and low energy, are all classic symptoms. You won't necessarily be deaf but you may notice some loss of hearing or none at all.

As the name suggests it is inherited through the maternal line. It is generally progressive.

I just looked at your profile and see you are marked down as type 1 - is this definitely the case i.e. were anti-bodies found in your pancreas? If so then you have type 1 but if not and you inherited your diabetes from maternal line you may wish to investigate whether you have mitochondrial diabetes.

Co-enzyme Q-10 and b vitamins may help with dealing with the symptoms such as fatigue if you have mito diabetes.

The fact that Diabetes is an autoimmune condition gives the clue , I was diagnosed in 1960 and had 20 yrs trouble free Diabetes
using Bovine Insulin . But in 1980 was converted to "Human" Insulin which within a month I was ill and is the cause of my 33yrs
of continually declining health , the diabetes networks are dedicated to Novo , they have the controlling interest in everything
diabetes (google "relationship with NHS and Novo Nordisk and up pops Oxford University with 7 Novo contact phone numbers ) .
I had to battle with NHS who were totally in denial of any problem , yet in 2006 it all came to a head ,my GP specialising in Diabetes refused me a 2nd opinion on the NHS , and after a 20 min stand up argument had to pay £150 to find out I had suffered
Poly Glandular Auto immune damage to 5 glands , the Chronic Fatigue was Thyroid destruction , the Pernicious Aneamia (GP said
blood tests showed I was perfectly well ) yet my Dentist got me a referral to Maxillio Facial which said it was serious , and most
important the cause of the 229 insulin coma`s destruction of digestive part of my Pancreas ,my Adrenal gland did recover after a year . Yes G/M Insulin does cause irreversable damage to certain patients , ( I was given a Derby news paper asking if you were having problems with the insulin would you be prepared to fill out a questionaire to assist 2 patients who had legal aid to fight a case , I did and was shocked hear I was 1303 to do so ,on asking how my symptoms compared she said you are all exactly the same , so its just you no longer stood up .

I get tired too. but my blood glucose is NEVER above about 7. In my case I put it down to age. However my mum, who has the same diabetes gene as I do and who is 95 said she felt especially tired, so I checked her blood glucose and it was 14.? So high sugars inhibiting oxygen transport could be the case.

I think the deterioration of the pancreas progresses to more and more fatigue as time goes on. While it is true that I asked my dr. to glyclazide diabetes drug, the fatigue is still there though a bit less than last year. I am vigilant about eating much less in case I have less fatigue because I would rather have fatigue with eating a bit more that getting hypoglycemia, which gives me heart pain and all the other nasty side effects which can last more than a day.
