大家好，我是Java1234_小锋老师，分享一套锋哥原创的LLM大模型 AI智能微信小程序个人健康管理系统(FastAPI+Vue3) 。

项目介绍

随着移动互联网与人工智能技术的快速发展，个人健康管理正由传统的医院诊疗模式逐步转向日常化、数字化和智能化。大学生及年轻群体普遍存在作息不规律、饮食结构不合理、运动不足等问题，但现有健康应用往往功能分散、使用门槛较高，难以与即时通讯场景深度融合。针对上述问题，本文设计并实现了一套AI智能微信小程序个人健康管理系统。

系统采用前后端分离与多端协同架构：服务端基于Python语言与FastAPI框架构建RESTful接口，使用SQLAlchemy操作MySQL数据库db_health；用户端基于微信小程序实现健康数据的随身记录与AI咨询；管理端基于Vue3、Vite、Element Plus和ECharts实现业务数据管理与可视化统计。系统涵盖用户注册登录、个人资料与密码管理、健康指标监测、饮食与运动记录、健康计划、健康资讯以及AI智能客服等功能。其中AI客服对接OpenAI兼容接口，结合健康领域系统提示词，为用户提供饮食、运动、血压血糖等常识性建议，并明确提示不可替代专业诊疗。

本文完成了需求分析、总体设计、数据库E-R设计、接口设计、功能实现与测试验证。测试结果表明，系统功能完整、界面简洁、数据统计直观，能够为个人日常健康管理提供可行的信息化方案，对同类微信小程序与Python Web应用的开发具有一定参考价值。
