## What You Can Ask

The AI assistant is designed for health-related conversations. Examples of things you can ask:

**Medications**
- "What is metformin used for?"
- "Can I take ibuprofen with my blood pressure medication?"
- "I missed my morning dose -- what should I do?"

**Vitals and Lab Results**
- "My blood pressure today was 145/90 -- is that high?"
- "My HbA1c went up to 8.2 -- what does that mean?"

**Lifestyle**
- "What can I eat at a hawker centre that is low in sugar?"
- "How much exercise should I do with my condition?"

**Appointments**
- "What should I prepare for my appointment next Tuesday?"
- "Can you summarise what happened at my last visit?"

## Health Insights

Beyond chat, the app surfaces proactive **AI Insights** on the Home screen:

- **Biometric alerts** -- "Your blood pressure has been above 140 for 3 consecutive days."
- **Adherence nudges** -- "You missed 2 doses this week. Would you like a reminder?"
- **Lifestyle tips** -- "High-sodium meals have been common this week. Here are lower-sodium alternatives."

These insights are generated by the Nudge Agent (A3) and Lifestyle Agent (A4) based on your logged data.

## Pre-Visit Summaries

Before a scheduled appointment, the AI generates a **Pre-Visit Summary** visible on the Appointments screen. It includes:

- A plain-language briefing of your health since the last visit
- Medications to discuss
- Questions to consider raising with your doctor

---

## Safety and Limitations

```{warning}
The AI assistant provides **health information and support only**. It does not replace professional medical advice, diagnosis, or treatment. Always consult your doctor or pharmacist for clinical decisions.
```

The AI is protected by the **SEA-LION Guard** safety system, which:

- Blocks harmful or misleading content
- Flags responses that require clinician review
- Escalates urgent health concerns to your care team automatically

If you receive an "Escalated to care team" message, your care team has been alerted and will follow up with you.
