# How GLP-1 drugs like Ozempic work

> A process map exported from forks.world (https://forks.world). Author: Brian. Source: https://forks.world/p/cmv0kpw610009jv06gqejmo4h
> It describes who does what, in what order, and with which technology. Read the plain-language sections first; the JSON at the end is the exact, complete data.

## Summary

- 13 steps across 1 layer
- Persona: You, Stomach and gut, Pancreas, Brain
- Technology / systems: The medication

## Pain points

Where this process hurts, worst first:

- **Appetite and weight often return** (How GLP-1 drugs like Ozempic work; critical): Debated: many people regain much of the weight after stopping
- **The dose is raised slowly to help** (How GLP-1 drugs like Ozempic work; painful): Common: nausea and an upset stomach

## How to read this file

- A process is made of **layers**. The main layer is the top level; any step of kind `subprocess` opens a detail layer with its own lanes and steps.
- **Lanes** are either persona (people/roles) or technology (systems). Each step belongs to one lane; `using` lists tools a person uses for that step.
- Step kinds: `start`, `task`, `decision` (its arrows carry the answer as a label), `subprocess`, `end`.

## How GLP-1 drugs like Ozempic work

Lanes:
- You: person / role (id `you`)
- The medication: technology / system (id `drug`)
- Stomach and gut: person / role (id `gut`)
- Pancreas: person / role (id `pancreas`)
- Brain: person / role (id `brain`)

Steps, in the order they run:

1. **Inject once a week** [start; You; id `g1`]
   - then It mimics a natural hormone, GLP-1
2. **It mimics a natural hormone, GLP-1** [task; The medication; id `g2`]
   - then Insulin rises when blood sugar is high
3. **Insulin rises when blood sugar is high** [task; Pancreas; id `g3`]
   - then The stomach empties more slowly
4. **The stomach empties more slowly** [task; Stomach and gut; id `g4`]
   - then Appetite signals drop and cravings quiet down
5. **Appetite signals drop and cravings quiet down** [task; Brain; id `g5`]
   - then You eat less without feeling as deprived
6. **You eat less without feeling as deprived** [task; You; id `g6`]
   - then Weight and blood sugar fall over months
7. **Weight and blood sugar fall over months** [task; You; id `g7`]
   - then Any side effects?
8. **Any side effects?** [decision; You; id `g8`]
   - if "Nausea or other effects" go to The dose is raised slowly to help; if "Mild or none" go to Do you keep taking it?
9. **The dose is raised slowly to help** [task; You; id `g9`] ⚠ PAIN POINT (painful): Common: nausea and an upset stomach
   - then Do you keep taking it?
10. **Do you keep taking it?** [decision; You; id `g10`]
   - if "Yes" go to The benefits continue; if "No — you stop" go to Appetite and weight often return
11. **The benefits continue** [end; You; id `g11`]
12. **Appetite and weight often return** [task; You; id `g12`] ⚠ PAIN POINT (critical): Debated: many people regain much of the weight after stopping
   - then Long-term plans are discussed with a doctor
13. **Long-term plans are discussed with a doctor** [end; You; id `g13`]
