For a lot of Type II diabetics, the oral meds (pills) only get you so far, and then you have to add insulin. Type II diabetes, which typically develops later in life as teens or adults, and is associated with being overweight and with metabolic diseases, happens when the insulin-secreting cells in the pancreas “poop out” and don’t produce enough natural insulin to control blood glucose levels. Sometimes DM II can be controlled or even reversed by major (major, major) diet and exercise changes, but sometimes it just needs life-long medications.
For Type I diabetics, including those with juvenile-onset diabetes, later-developing autoimmune diabetes, steroid-induced diabetes, and those who had their pancreas removed, or their pancreas stopped producing insulin, the oral meds would never have worked, because the Islets of Langerhans in their pancreases don’t produce insulin at all, or because their pancreases have been removed (pancreatic cancer; chronic pancreatitis), so they’ve been on insulin injections from the get-go. This often happens with those who had liver problems, as the pancreas is sort of a next-door neighbor and can be damaged downstream from problems with the liver.
All this is a big reason why treatments that might work for one person with diabetes might not do diddly-squat for another.
Anyway, hope you guys can find treatments that work for you and that also work with you.
