[eli5] what are the different types of diabetes and the causes of each?
gpt
\-Type 1 diabetes - body thinks cells that make insulin are bad, kills them (autoimmune not diet) Oopsies part of your pancreas is dead now you take insulin for life 24/7/365. Used to be called juvenile diabetes, can happen at any age, nothing to do with diet/lifestyle.

\-Type 2 diabetes - a few sub types but basically the body makes too much insulin and doesn't know what to do with it (metabolic syndrome-depends on subtype you can treat it with a lifestyle change, oral meds or insulin in people who are super resistant to it or have had it for years and oral meds/diet isn't helping) 
*Edit for clarity (thanks to an RN in this thread): The resistance is not the result of insulin overload. The resistance is due to the fat surrounding muscle cell, insulin can’t work, glucose builds up in bloodstream and down the road, insulin builds up. 

\-Gestational diabetes - in pregnancy, sometimes the placenta goes brrr and there is a hormonal imbalance. It resolves (clears up) after pregnancy in most cases

\-Maturity onset diabetes of the young (MODY) - a genetic disorder with different subtypes. Some are treated with type 1 treatments, some are treated with type 2 treatments. Shows up in young people who aren't type 1 or type 2 and you need a genetic test for this

\-Neonatal diabetes - poor babies because it hsows up before 6 months of age :( and can stay with you for life or show up randomly throughout your life. Super rare, really super rare.

\-Wolfram Syndrome - everyone who has this rare syndrome will get diabetes that is treated the same as type 1. So it's like a bonus for having this syndrome and then you get T1 on top of it

\-Alström Syndrome - see above but this syndrome will cause type 2.

\- Latent Autoimmune diabetes in Adults (LADA) - not a disease on its own but put here for people to understand type 1 can happen at any age.  LADA (1.5) is just a slower developing type 1. So let's say you're 10, you get T1, you get DKA you're in hospital fighting for your life and this happens very quickly. You can be an adult with the same thing but it happens slower. So 1.5 is T1, just the onset is slower.

\- Type 3c diabetes - owie to pancreas. Accident, disease, surgery and part of your pancreas goes bye bye. Congratulations--you are treated the same as type 1

\-Steroid-induced diabetes - can be permanent, can be temporary. Steroids make your blood glucose go super high. Can be steroids from cancer treatment, can be steroids from people who don't know better and take steroids for fun, etc etc.

\-Cystic fibrosis diabetes - cystic fibrosis doesn't like some organs. It attacked them too. Pancreas attacked with sticky mucous, and you can get either type 1 or type 2, depends on how your CF develops.
