AZ vaccine cause of Diabetes

Wondered if anyone has heard of any link between THE vaccine and causing either heightened symptoms (high blood sugars) and taking the AZ or other Covid vaccine or even causing Diabetes ? Someone I know, not a diabetic, had final jab 3 weeks ago and has had all the classic symptoms (excessive toilet visits, drinking heavily, fatigue etc) since. Did a BS with him and he was 24. Likely diagnosed with Type 2 and I hope not type 1. Seems too much of a coincidence!
 
Hi @MightyThor ! Of course the body's response to a vaccine is for the immune system to respond. The hope is that the body produces antibodies tailored to fight off the 'infection'. However the immune system can and may respond in other ways, depending on the person, which may include cytokines and inflammation. Could these processes lead to damage to the pancreas? Who knows.. but so far there is absolutely no data that suggests a causal link between COVID vaccines and diabetes.

Speaking for myself, I had my first AZ jab at the start of March and developed Type 1 a few weeks later.. but this is probably just co-incidence.

@MightyThor our bodies react to things like illness, drugs, vaccinations, .... by releasing glucose to fight them.
So, it is not uncommon for someone with diabetes whether undiagnosed or not to experience higher blood sugars after any vaccine. This does not mean the vaccine caused diabetes; it means the body's response to the vaccine caused the blood sugars to rise and the body was unable to respond to that rise.
I suspect (but I am not a doctor), your friend already had undiagnosed diabetes which reacted to the vaccine.

As for hoping it's not Type 1, why?
No type of diabetes is good but no type needs to be a death sentence.
And no type is worse than the other - Type 1 and type 2 both have their downsides and comparatively upsides.
For the sake of any newly diagnosed, scared people with confirmed Type 1, please take care not to suggest it is "The Worse Type".
 
I am not a big fan of vaccines for those that don't need them for this disease but type 1 often starts in response to some kind of viral infection so if it was type 1 then he could have got a nasty flu or pneumonia and just been unlucky in how his immune system handled it.
If type 2 then that doesn't develop overnight. Its been going on for 10-15 years as insulin levels get high, cause insulin resistance until the body cannot push out enough insulin to keep excess sugar out of the blood. A temporary spike may occur during any infection or triggering of immune response but a diagnosis would involve not just a one off blood test but a longer term average bg plus symptoms.
As I understand it some very frail people have not been able to handle the vaccine and there have been some incidents of blood clots (2 in 1000) though side effects are under reported so it is hard to know and still harder to link health events to the vaccine when they commonly occur in a population that's been so heavily vaccinated (no control group).
I've got type 1 so am not offended at all that you might hope it was not that one as it is a pain to deal with!

I have read several studies wondering whether covid can cause diabetes.
Can coronavirus cause diabetes, or make it worse? | Diabetes UK

As for the vaccine, it's not unusual for them to push blood sugars up temporarily, but I agree with @In Response 's theory that your friend was possibly already diabetic or even prediabetic, he just didn't know. And one high reading of 24 isn't enough to diagnose anyone with diabetes, though I agree it makes it a strong possibility.

Given the number of vaccines administered, it seems likely that there would have been some studies linking the vaccine to increased numbers of diabetes diagnoses if it was a causal thing, People don't like to believe in coincidences but they genuinely explain many many things. (eg if you have a room of 23 people then there is a 50% chance that two will share a birthday, counter intuitive to most people, but mathematically provable.) The fact is, lots of people get diagnosed with diabetes every year, and lots of people have been vaccinated. It's not at all strange that some people should have this happen 3 weeks apart. You just happen to know one of those people.
 
I would guess these cases were probably border line anyway !
 
Also some perspective here. 10% of the population has elevated blood sugar (and a much higher percentage of people over 40), be that diabetes or pre-diabetes. When 80% of the population have had at least one jab, there are going to be a significant number of people who are diagnosed with diabetes shortly after the vaccine. It would be more strange if that wasn't the case. Correlation isn't causation.

I was diagnosed the day after I had my second jab (and pretty much exactly three months after my first, fitting in nicely with the timing of the way A1C works). Coincidence? Absolutely.
 
Before the vaccine roll-out, 700 people a day were being diagnosed with diabetes in the UK. https://mrc.ukri.org/documents/pdf/diabetes-uk-facts-and-stats-june-2015/ That's nearly 15,000 people in the 3 weeks since your friend had the vaccine. The only way you can see if the vaccine has any effect is to look at large numbers of people who've had the vaccine to see if their diagnosis rate is greater than that which was occurring before the vaccine was introduced. It's very likely that some research group is doing this. We can't conclude anything from just one person's experience and always have to beware we don't fall prey to the post-hoc ergo propter hoc fallacy. https://en.wikipedia.org/wiki/Post_hoc_ergo_propter_hoc

Nicole, blood clots are more like 1 in 100,000 (depending on age)
COVID-19 vaccination and blood clotting - GOV.UK (www.gov.uk)

In any case, I have to be careful what I say because this is in danger of going off topic, which is whether anyone has heard of the vaccine causing diabetes and whether it's just a coincidence that the OP's friend has (probably) got diabetes soon after his vaccination. If anyone (including me) wants to start a new topic, they should create their own thread.
 

A random finger prick BS test reading of 24 doesn't always mean T1 or T2 diabetes.
Many things can spike BS for anything form minutes to a couple of weeks or more:
1.Immediately after eating tropical fruit or baked goods.
2. Stress
3. Lack of sleep
4. Injury
5. Lack of sleep
6. Medications including Statins and Steroids.

In the UK the gold standard test for diabetes is 2 x HbA1C test readings of 48 or higher 1 month apart.
