Type 2 diabetes feedback loops

This causal loop diagram summarises a feedback pattern often used to explain progression in type 2 diabetes. Insulin resistance can raise blood glucose, which raises the demand placed on beta cells. Sustained stress can reduce insulin secretion over time, allowing glucose to rise further. Glucotoxicity is included as another route by which elevated glucose may worsen beta-cell stress. The signed arrows help learners check whether each link moves in the same or opposite direction. This is a simplified teaching model: real disease progression also involves genetics, body composition, medicines and many other factors. It should not be used to diagnose a person or to choose treatment. Add variables only when their causal direction can be explained clearly.

“Create a causal loop diagram for type 2 diabetes with insulin resistance, blood glucose, insulin demand, beta-cell stress, insulin secretion and glucotoxicity. Show a reinforcing loop in which high glucose increases beta-cell stress and reduced insulin secretion raises glucose.”

Qué hay en este dibujo

Lee las decisiones que hay detrás.

01Variables

Use measurable physiological states.

02Polarity

Mark secretion as lowering glucose.

03Delay

Show the gradual beta-cell response.

04Loop

Name the glucose-stress feedback.

Use as a teaching overview, not for individual diagnosis or treatment.

Preguntas frecuentes

Preguntas habituales

Why is this a reinforcing loop?

Higher glucose can contribute to processes that reduce insulin secretion, which can then increase glucose further.

Why is there a delay?

Beta-cell stress and functional decline generally develop over time rather than immediately.

Is this a treatment plan?

No. It is a simplified teaching diagram and not clinical advice.
