Why Is Diabetes Genetic?

The Genetics Of Diabetes

Why me? How did I deserve this? Am I to blame? These are questions that many people ask when diagnosed with a serious condition or disease. Unfortunately, there’s no clear-cut answer when it comes to diabetes. Unlike some traits, diabetes doesn’t seem to be inherited in a simple pattern, and there is a lot of misinformation out there about its causes. (Have you ever had to explain that diabetes doesn’t happen because someone ate too much sugar?) It’s apparent, though, that some people are born more likely to develop diabetes than others. We know that type 1 and type 2 diabetes have different causes, but genetics plays an important role in both types. People with diabetes inherit a predisposition to the disease, then something in their environment triggers it. Identical twins are proof that genes alone are not enough, however. Identical twins have identical genes; therefore, they should have the same genetic risk for a disease—right? Not necessarily. Research has found that if one identical twin has type 1 diabetes, the other twin will get the disease about 50 percent of the time. For type 2 diabetes, that risk rises to as much as 4 in 5. In both type 1 and type 2, identic Continue reading >>

    Hello r/diabetes!
    I'm a 30 year old type 1, I've been diabetic since age 8. I've kept a good A1C and overall have a great handle on things. My doctor has me currently on humalog and lantus, and since it's been working so well we have never discussed switching to another type of insulin. I use the Humalog on a sliding scale, and over the years I've gotten so used to it that I can basically hit my dosage on the head every time based on my blood sugar levels and what I eat. I'm not on any specific diet plan or anything, I just get my humalog whenever I eat or my sugar rises (I check my sugar A LOT lol).
    I recieved a letter this weekend from my insurance company (Blue Cross/Blue Shield of NC) stating that they were taking Humalog off of their "preferred tier" of copay. I called and found out it's going all the way to the maximum copay amount (based on my research it will cost roughly $100 per month vs my current $35). The only fast acting insulin remaining on the preferred list is Novolog.
    Scheduling an appointment to see my doctor between now and Jan 1 (when the new pricing begins) is next to impossible, though I am trying. I know I can get a prescription for Novolog without actually seeing him, and I know that the two are roughly equivalent.
    So I was hoping some of the fine folks here might be able to tell me their experience with switching from one insulin to the other. Similarities, differences, etc. Based on what I've read they are essentially interchangeable, but I know that things are rarely that simple.
    And a bit more info just in case: I won't consider a pump at this time. I cant switch insurance because I get it through work.
    EDIT: Thanks for all of the replies! Definitely eased my mind a bit. I was actually able to get an appointment to see my doctor on Dec 1 for a quick consultation and to get everything switched over.

    I have switched a couple times over my thirty three years as a Type I and the last thirteen with a pump, usually for the same reason that you're being forced to switch. I've never had a problem with the switch, the same dosage worked perfectly and I never even know I'd switched. Obviously, YMMV, but I wouldn't worry too awful much about it.

    Thanks! The dosage was my main concern. I am so used to Humalog I would probably struggle at first if the dosages were different.
