Prompt: Potassium Restriction Dietary Guidance Letter

Potassium Restriction Dietary Guidance Letter

Use this prompt to draft a practical dietary guidance letter for a patient with CKD who has been advised to reduce their potassium intake. This letter bridges the gap while waiting for a dietitian appointment.

Draft a dietary guidance letter about potassium restriction for a 
patient aged [[patient_age — e.g. "60"]] with CKD and raised 
potassium levels (hyperkalaemia).

The letter should:
- Explain in plain English why potassium levels need to be managed 
  in kidney disease (kidneys clear less potassium; excess affects 
  heart rhythm)
- Describe the main categories of high-potassium foods to approach 
  with caution — not a comprehensive list, but the key categories: 
  many fruits (especially bananas, oranges, dried fruit), root 
  and leafy vegetables, nuts and seeds, chocolate, potatoes
- Explain that cooking vegetables by peeling, boiling in a large 
  amount of water, and discarding the cooking water can reduce 
  potassium content
- Acknowledge the difficulty of this if the patient has been told 
  to eat plenty of fruit and vegetables for other health reasons — 
  explain this is a specific kidney-related need
- Note that a dietitian will provide more specific individual advice
- Tell the patient not to make major dietary changes without 
  discussing them at the next appointment

Do not give specific quantity limits. Tone: practical and non-alarmist. 
Maximum 400 words.

Why this works

Explaining the cardiac safety reason for potassium restriction — not just "your kidneys need it" — helps patients understand why this is not an optional recommendation. The acknowledgement of the conflict with general dietary advice (eat more fruit and vegetables) addresses one of the most common sources of patient confusion about CKD dietary guidance.

How to tweak it

• For a patient who is vegetarian or vegan, add: "Note that this patient has a plant-based diet. Acknowledge this and suggest they discuss with the dietitian how to manage potassium restriction while maintaining nutritional adequacy on a plant-based diet."
• For a patient on dialysis, add: "This patient is on haemodialysis. Note that potassium management on dialysis is different from pre-dialysis, and that the dialysis team will provide specific guidance on timing of dietary potassium intake around sessions."

Remember: AI is a helpful assistant, not a clinician. You make the call.
