OVERVIEW

It takes more than just prescription drugs to continually lose and maintain weight.

Henry Meds is committed to making healthcare more accessible—one of its key product helps individuals struggling with weight management with the support of GLP-1 medications.


However, prescription drugs alone aren't enough to sustain long-term weight loss. Many users cited “treatment unsuccessful” or “results too slow” as one of the primary reasons for leaving the program. While weight-loss medications affect everyone differently, success stories showed that healthy habits—like consistent hydration, regular physical activity, and mindful eating—can significantly support progress.


As the lead designer on this project, I uncovered insights through user surveys and feedback. I led the cross-functional initiative to test the hypothesis that weight-loss journey through personalized weight tracking paired with education could help patients stay motivated toward their goals, guide healthier habits and have more informed conversations with their providers.

Business Value

Key Findings

I gathered initial information and data from our recent user research from Maze and from the consumer insights team.


What we learned from the consumer retention analysis:

  • Patients who use a weight tracker are more likely to lose weight.

  • Interacting with a weight tracker even once would help retain patients.


and from user research (Maze):

  • Patients wanted a plan adjusted based on their progress and setback.

  • They also value education and access to professionals.


To better understand what patients need from providers during their visits, I facilitated a brainstorm session with the Clinical team.


Some friction points I learned were:

  • Patients sometimes estimated how much their weight fluctuated. This made it harder for providers to fully guide them at points when they might need it most.

  • Often times, patients are unsure how to start their weight-loss journey (including water intake, side effects, and more).


This provided a base to move forward with building a weight tracker that's educational and supportive of a behavioral change during the patient's weight-loss journey toward healthy long-term habits.


In 4 weeks, we launched a personalized weight tracker in the Patient Portal and saw an increase in engagement with 76% of users recording their weight weekly. In addition, I saw an opportunity to work with the EHR team to integrate the weight data into EHR for providers to see how the patients were progressing.

Early design & consideration

Build quickly to test if the feature would be used by patients.

To kick things off, I partnered with product and engineering to align on requirements, constraints, and timeline. Our goal was to launch an MVP to test whether this would be a good fit for our patients, then iterate based on feedback.


I conducted a competitive analysis to identify common patterns and key components found across similar tools. From there, I sketched out early concepts, referenced our design system and noted where we might need to create new components in collaboration with engineering. I quickly prototyped ideas to share with the team and presented early directions to leadership for alignment.


For the MVP, I focused on the essentials: showing users' measurements (starting, current, and goal weight) that synced to patient's intake forms. I then added a weight tracker that allowed patients to record and view progress over time. Finally, I worked with marketing to craft and personalize helpful tips based on each patient’s journey.


In addition, I worked with our compliance team to ensure the experience met HIPAA standards for handling patient data. One key consideration was around historical weights: we needed to preserve patient-recorded data. Based on this, we allowed patients to log their weight multiple times a day, displayed the most recent entry on the graph, and kept a secure history of all previous entries—unaltered and accessible for provider review.

mvp launch & learnings

Support tickets blew up. What happened?

After releasing the MVP version of the weight tracker, we started getting feedback from the customer care team—support tickets were piling up from patients asking to update their historical weight entries. Most of the time, it came down to simple human error, like typos during intake.


In the interest of moving quickly, we had initially relied on the accuracy of the intake form data and allowed patients to log their weight multiple times a day to ensure recency. But we didn’t give them a way to edit those entries. As a result, any corrections had to go through support, creating an inefficient and inconsistent workflow—not to mention adding extra burden to the team.

survey

What we learned about patients' interaction with the weight tracker.

I worked with the consumer insight analyst to craft a survey to our weight management patients to gauge patients' interactions and feedback about using the weight tracker.


What I learned:

  • 78% of patients are motivated by seeing their progress over time

  • 38% would use Henry Meds weight tracker if they were sent notifications/reminders

  • 45% wanted to see personalized health tips based on their progress


These survey feedback were valuable in shaping the iteration.

Iteration

Improving the experience to make weight tracker more useful for patients.

After launch, we gathered feedback through user surveys and direct support conversations. I partnered closely with the product manager and engineering team to prioritize iteration work, focusing on three main areas:


  1. Giving patients more control over their weight entries

  2. Making progress feel more visible and encouraging

  3. Encouraging consistent engagement through reminders


1. Solving for weight typos
One of the biggest friction points was patients needing to correct mistakes in their logged weight data. To reduce reliance on support and give patients more autonomy, I designed a weight history view. This let users see a full log of their entries, and take action on individual records (edit or delete), while still respecting compliance constraints.


2. Making progress feel real
We learned from feedback that the original graph didn’t feel motivating—some patients missed the small hints we included, and many didn’t feel like they were making progress at all. To fix this, I designed a personalized journey card that highlighted how far patients had come—offering encouragement when things plateaued and celebrating small wins along the way.


3. Supporting consistent engagement
From research, we knew long-term success hinged on regular tracking, so I started designing reminder settings that let patients choose if and when they wanted to be notified. At the same time, I collaborated with the email marketing team on automated reminder emails. Leadership initially pushed to send reminders to every patient weekly, but we quickly rolled this back after hearing that some patients found it discouraging or even triggering. In the end, we implemented the original vision: giving patients control over their reminder preferences, creating a more empathetic and effective experience.

EHR platform for patient weight tracking.

integrating with ehr

Allowing for a more comprehensive patient and provider encounter.

Providers were excited for weight tracker.


Early on, providers highlighted that patients sometimes estimated their weight which made it hard to guide them clearly. I saw the opportunity to discuss integrating weight data to the patients' chart with the internal apps team. This benefitted providers greatly in two ways:


  1. It was especially helpful for providers to review patient information and evaluate their prescription during async appointments

  2. It allowed for a comprehensive chat between providers and patients during a provider visit.


I worked with the designer on the internal tools EHR team to build the tracker with the core data point to the patient chart.

Throughout this project, I learned a few key lessons that has shaped how I approach projects today. 


Use available research and data to guide MVP

I was able to sketch out early wireframes by leveraging user surveys (Maze) and consumer insights to help me frame what the minimum viable product for weight tracker to be able to deliver value to Henry Meds patients.


Opportunity to align feature work with cross-functional team

It's important to listen to the other side. Early on, through conversations with providers, I learned that patients often estimate their weight during provider visits, making it hard for providers to have a clear view into patient's progression with their medication. This helped me advocate to add this feature with the internal apps team once validated with my team.

Outcomes & Impact

Launched the weight tracker in the Patient Portal.

The weight tracker was released and iterated on the weight tracker in the Patient Portal in 4 weeks, going through discovery, initial launch, feedback and iteration, and QA testing. Here's what we saw:


  • A majority of patients recorded their weight at least once per week, indicating that weight progression is how they track their weight management journey.

  • About 20% of patients clicked on the educational link to learn more.

  • Patients have said that they "only track through Henry Meds"

  • With the updated weight edit, support tickets decreased significantly.

  • Providers reviewed patients' charts prior to meeting patients and have a more informed conversations with patients on titration, dosage, and next steps.
