Only diabetes I is inherited.

Change your diet away from added sugar towards more natural stuff and you can cure any pre-diabetes and even diabetes II. In particular stop the constant snagging of sweets and you should be fine. Also no sodas or shakes etc.

I was diagnosed with type 1 about 15 years ago (my sugar was over 1300 and in the hospital for almost a week). Was able to get off of insulin after several months and mostly stay off of it for a number of years keeping it under control with exercise and diet (but sometimes having to go back on insulin for a couple of months). One thing I noticed over the years is I have more problems in the winter months (Dec-March) than rest of the year, and the amount of exercise doesn't change much during the year (diet might with holidays, more people bringing donuts to work, etc). Throughout the years I would check typically 1/day to every other day when under control, but other times 3-5/day when trying to figure things out. Recently (not even a month ago) I switched to freestyle libre CGM for checking my sugar which makes it checking frequently very easy. It checks something like every 5 minutes, but you can check upto once a minute. It gives very useful plots, especially to see what impact exercise has, what different foods cause to spike or not change things much, how quickly or long it takes for sugar levels to start to rise or fall, etc... The cgm sensors costs a little more than taking insulin or other medicine, but I prefer to keep it under control by exercise and diet as long as I can. I already noticed sometimes I can feel hungry, and based on when I last eat I would expect my sugar levels to be more normal but they would be high... I don't eat the same things consistently, but I think I am going to start having eggs for breakfast more often and cereal less often (eggs don't even register, and cereal spikes a fair bit).

I probably abuse sugar though not as much as I did when I was younger. But since I never go see doctors (I hate doctors) I am good to go. If no doctor tells me that I have a condition then It's like I don't have a condition. So all those exams one is supposed to do in life are not for me. I'm not about to let some quack stick a finger up my ass to check my prostate, no sir, no thanks.
So about diabetes, I don't want to know if I have it or not. I assume I don't and I'm happy just assuming.

My grandfather was diabetic.

Basically you are saying:  Ignorance is bliss...  why live an extra 10 years if it means worrying about things, and hope to go out quick instead of living longer trying to keep a chronic condition under control that slowly destroys your body...  we are all going to die anyway, it's not worth trying to prolong it.  better to live to 50 and enjoy life then live to 60 but having to be extra careful with what you eat, etc....   (just hypothetical numbers)

I tend to be that way too, but my wife and family don't agree... and sometimes you have to think about those you would leave behind sooner by not knowing about a condition before you end up dead or in the hospital.

Y'all are going to regret thinking like this if you get prostate cancer and only finding out at 45 in the emergency room that you will have 1 month left to live with atrocious pain when you could just have it check before and get it fixed before it's too late. Getting checked isn't living in fear but NOT going is. It's not from being scared of facing the truth that you will suddenly not get really sick and die.

Also, not only is it really important if you are in a relationship, I think it's important to see if you have something going on or even just not let your partner and family down at a young age just cause you were scared.(idk maybe you have a family or a really long term relationship)

Type 1 sucks and it's not your fault if you have it and I really am sad about whoever get diagnosed with it so is type 2. But anyone complaining about type 2, you can easily turn it around so if you don't change your routine (which is obviously terrible for you if you have type 2 and would feel way better if you fuel your body with good stuff) then it's cause you are happy with having it.

Mine is type2. What worked best for me, is the complete annihilation of carbohydrates.

Doctors will tell you that you need to have them, but it's not true. If you don't carbohydrates you can be pretty dman healthy, especially if you're only pre-diabetic.

My blood sugar used to be 120 to 130, back when I listened to the doctors. But with my new diet, it has come down a lot. My sugar has decreased to around lower 80s, sometimes even less. And I eat plenty of fat, eggs, butter, meat. As long as you kill carbohydrates, it's fine.

This man gets it, cut out as much carbs as you can, eat non-processed foods rich in fat (this will now be your main energy source), eat vegetables, and very importantly exercise regularly, bingo! Diabetes under control or gone altogether..   

If your now using insulin due to your pancreas dying, unfortunately you will have to take some supplementary sugars   

If you have to use medication, first line should always be Metformans as they only reduce insulin resistance in your fat cells, once that doesn't work anymore a combination of Metformin and a Sulfonylurea is ok, but keep in mind Sulfonylureas will over-work your pancreas to produce more insulin, eventually killing it, before you get to that point and have to use insulin injections, go full hog on a very low carb diet (not low fat) and plenty of exercise      

Diabetes is a Western lifestyle disease, poor (carby) diet, and little exercise, we all have it in our control to avoid this disease (unless Type 1) 

If anyone doesn't know where to start on the exercise, first step (literally) is to walk everyday, get off your ass, the next step would be cycling, it's low impact, uses large muscle groups (great for burning up sugars and keeping your metabolism up for days), and enjoyable for most people, that's it
