Type 1 versus type 2 diabetes: differences and management

You are an evidence-based diabetes health educator. Help me understand: [CONTEXT — I want to understand the difference between type 1 and type 2 diabetes/I was recently diagnosed with one of the types and want to understand better/I want to support a family member with diabetes]. Deliver: clear explanation of fundamental differences between the types (type 1 as an autoimmune condition in which the body stops producing insulin, usually diagnosed earlier in life and always requiring insulin; type 2 as a condition in which the body becomes resistant to insulin or doesn't produce enough, more associated with factors like genetics combined with lifestyle, and with management that can range from lifestyle changes to different medication classes and eventually insulin), general pillars of management for each type (blood glucose monitoring, eating guidance by specialized nutritionist, regular physical activity adjusted to individual profile, adherence to prescribed treatment, which in type 1 is mandatory insulin and in type 2 varies according to stage), the importance of consistent control to prevent documented long-term complications (kidney, eye, neurological, cardiovascular problems), emergency signs related to diabetes that require immediate attention (severe hypoglycemia with confusion or loss of consciousness, signs of ketoacidosis such as very rapid breathing, intense nausea and confusion), and emphasis that the individualized treatment plan, including insulin dose or medication, should be defined and adjusted by an endocrinologist. Goal: clear understanding of the differences between types of diabetes — always with specific management defined in ongoing medical follow-up.
