The goal of this trial is to learn whether wearable devices and hormone sampling can measure how the body changes during daily-life challenges in adults with endocrine or metabolic disorders. These disorders include conditions such as high blood pressure, adrenal disorders, diabetes, obesity, thyroid disorders, pituitary disorders, and other hormone-related conditions.
The main questions it aims to answer are:
Can wearable devices measure changes in blood pressure, heart rate, sleep, activity, temperature, and glucose during changes in salt intake, meals, fasting, and short exercise? Do these changes differ between people with different endocrine or metabolic disorders? Are wearable devices acceptable and practical for participants to use at home?
There is no comparison group in this study. Each participant will serve as their own comparison by completing different study phases.
Participants will wear study devices at home to measure blood pressure, heart rate, activity, sleep, temperature, and glucose, follow a low-salt diet for about 1 week and then a high-salt diet for about 1 week, using study instructions, complete meal, fasting, and short exercise tasks, give urine and saliva samples, and possibly blood samples, during the study. Optionally wear a hormone sampling device for about 27 hours, complete short questionnaires about symptoms, sleep, physical activity, and their experience using the devices.
The study will help researchers understand whether wearable monitoring can support future diagnosis and care for people with endocrine and metabolic disorders.
Inclusion Criteria:
Diagnosis or suspected diagnosis of at least one endocrine or metabolic disorder, including:
Exclusion Criteria:
Participants will complete a single-arm, within-participant home-monitoring protocol. All participants will first undergo baseline monitoring, followed by sequential low-sodium and high-sodium diet phases and clinic-based phase. During these phases, participants will wear study devices to measure blood pressure, heart rate, heart rate variability, activity, sleep, temperature, and glucose. Mixed-meal, fasting, postural, and short exercise modules will be included when appropriate. Optional dynamic hormone sampling will be performed in participants who provide separate consent.
