A health headline can introduce a term that sounds like a new diagnosis. “Type 3 diabetes” is one example. Before changing anything about your care, ask what the phrase means and whether it applies to the question you have.
A research phrase needs context
“Type 3 diabetes” is an unofficial term sometimes used in discussions of diabetes and Alzheimer’s disease. It is different from type 3c diabetes, which is caused by damage to the pancreas. Diabetes UK — Dementia and diabetes.
Research language should not be treated as a diagnosis you can make from a headline or a list of symptoms.
What should you do with a concern?
If you are worried about your memory or changes in everyday functioning, book a GP appointment. Diabetes UK recommends speaking with a GP about memory or concentration concerns. Diabetes UK — Dementia and diabetes.
Bring a few examples in your own words. You could note what has changed, when you first noticed it and what you want to ask. A support person can come with you if you would find that useful.
If you already receive diabetes care, take questions about your treatment to that team. Do not use this research term as a reason to start a new diet or supplement plan.
Keep everyday choices in perspective
Cooking a meal, spending time with someone or returning to a familiar hobby can still matter to you without being presented as an Alzheimer’s treatment.
