Diabetes Care
Interactive mockup of seven expandable cards, each describing one NBDC biochemical node in plain language with what drives it, what it costs, and what it feeds.
The framework
Network Based Diabetes Care
Seven biochemical pathways that decide where sugar goes, what it damages, and how quickly it can be brought under control. Tap any node to see what drives it.
1
The main road
Glucose consumption · GCN
The pathway that burns sugar for ordinary energy. When it backs up, everything downstream starts to fill.
What drives it
Every meal, and how fast it arrives in the bloodstream.
Every meal, and how fast it arrives in the bloodstream.
What it costs
Nothing, while it keeps up. Rising fasting sugars are the first sign it can't.

What it feeds
Overflow into the polyol and hexosamine routes.

2
The engine room
Citric acid cycle · TCA
Where fuel becomes usable energy. What this engine can handle sets the ceiling for everything else.
What drives it
Total fuel arriving — sugar and fat together, not sugar alone.
Total fuel arriving — sugar and fat together, not sugar alone.
What it costs
Fatigue that doesn't match the day. The engine is running rich and inefficient.

What it feeds
Backpressure onto quality control, which absorbs the strain.

3
The repair shop
Pentose phosphate · PPP
The supply line for antioxidant defense and rebuilding. High sugar drains it faster than it refills.
What drives it
Demand for repair — which rises the longer sugars stay high.

What it costs
Slow healing, frequent infections, damage that outpaces recovery.

What it feeds
Nothing directly. When it's empty, every other node loses its safety margin.

The overflow drain
Polyol pathway · POL
The route sugar takes when the main road is full. It runs through nerves, eyes, and kidneys.
What drives it
Sugar with nowhere else to go. It opens only when the main road is saturated.
Sugar with nowhere else to go. It opens only when the main road is saturated.
What it costs
Burning or numb feet, changing vision, early kidney findings — often before diagnosis.

What it feeds
It drains the repair shop, removing the defense that would have protected those tissues.

The tagging system
Hexosamine pathway · HBP
A labeling process that quietly changes how cells read insulin's signal.
What drives it
Sustained excess sugar, read by the cell as a signal that fuel is abundant.

What it costs
The same medication dose doing less than it did a year ago.

What it feeds
It turns up the switchboard, and makes the main road harder to reopen.

The switchboard
Protein kinase C · PKC
An amplifier for messages inside the cell. Overdriven, it turns a metabolic problem into a blood-vessel problem.
What drives it
Byproducts of a saturated main road, amplified by the tagging system.

What it costs
Rising blood pressure, stiffer vessels, protein appearing in the urine.

What it feeds
Pressure onto quality control, and more demand on the repair shop.
Pressure onto quality control, and more demand on the repair shop.

Quality control
Unfolded protein response · UPR
Catches damaged proteins before they accumulate. When demand outruns it, the cell shifts from managing stress to signaling distress.
What drives it
Strain arriving from every other node at once.

What it costs
Insulin-producing cells that stop keeping up — the point where the condition changes character.

What it feeds
Back into the main road. This is where the network closes into a loop.

No node fails alone. Pressure in one pushes into the next — which is why the order of intervention matters more than most people are told.
