I’m 25 years old and i have been diagnosed with type 2 diabetes 6
months ago.Until recently i had been able to maintain my blood glucose
to acceptable levels with diet and sports.But since 2 months my blood
glucose is higher and i find it very difficult to maintain it at
acceptable levels even if i do alot more physical activites and eat
well. I wonder if it’s possible that i have type 1 diabetes instead ?
I know that peoples with type 1 diabetes don’t produce any insulin and
need insulin injections.But does that “stop” of insulin production
happen immediately or is it over time ? i mean does one day your body
produces insulin normally and the next morning you wake up and your
body dosen’t make any insulin , or is it slowly decreasing over time
(1 year for example) ? And if it’s slowly decreasing , how much time
does it take on average ?

It is entirely possible that you are an adult-onset T1.

Adult-onset T1 are thought to outnumber juvenile-onset T1 by perhaps as much
as 2:1

An adult-onset T1 honeymoon  (period in which insulin injections are usually
not absolutely necessary) varies in length from person to person.   In
general,  younger folk like you can expect to see “stuff happen” in 6 months
or so.  Old F*rts like me can drag it out for a couple of years.

In general, it’s a slow and steady decrease in insulin production..
However, since most of an Adult-onset T1’s beta cells have already been
destroyed by the time anybody notices he’s diabetic,   a little bit more
destruction can have a strong effect on blood sugars.

“Non-obese” and “well-exercised” are two very strong indicators of
adult-onset T1 in a newly diagnosed diabetic.   If you fit that description,
you must be aware of a special danger which folks like you face:

You must never allow the simultaneous presence of

a.  High blood sugars, over 200 mg/dL and
b.  Ketones in your urine.

That’s a sign of Diabetic Ketoacidosis, a serious, life-threatening
condition which afflicts adult-onset T1 at the end of their honeymoon if
they don’t switch to insulin soon enough.  The “cure” is immediate injection
of insulin.

DKA is always a problem for all T1 but if you know you are T1 and have
insulin in your possession, it’s easy to treat.
