How to Track POTS Symptoms

Updated 29 Oct 2026

POTS can change from morning to evening and from one week to the next. Between appointments, the details that explain a hard stretch, such as a hot day, a skipped drink, or a long wait in line, are easy to lose.

This guide explains how to track POTS symptoms in a short, repeatable format: what to record each day, how to log heart rate and upright symptoms, how to note fluids, salt, meals, and heat, how to keep tests and medicines in order, and how to bring the pattern to a visit.

What POTS symptom tracking is and what it covers

POTS symptom tracking means recording symptoms, upright time, triggers, and treatments in the same short, dated format every day. Standing tolerance changes with heat, fluids, and sleep. A short daily entry lets you compare a heat wave, a new medicine, or more fluids with your steadier weeks.

The NHS describes POTS as a heart rate increase after getting up from sitting or lying down, often with dizziness or lightheadedness. Symptoms on standing can include palpitations, chest pain, shortness of breath, shaking and sweating, and fainting or nearly fainting. Other symptoms include stomach problems, headaches, blurred or tunnel vision, fatigue, poor sleep, and brain fog (NHS). NINDS notes that POTS symptoms may come and go over time (NINDS).

The NHS notes that it can take time to be diagnosed, because symptoms are similar to other conditions (NHS). A dated record helps your clinicians see the whole picture. If you are new to logging, see how to start tracking POTS symptoms.

In POTS Journey, the Daily check-in records dizziness, heart rate spikes, salt intake, dehydration, and fog in the same guided fields each time, so weeks logged months apart can be compared.

What to record each day with POTS

A daily entry works best when it is short enough to finish on a bad day. The NHS notes symptoms may be worse in the morning (NHS), so note the time of day next to scores, and fill in the main entry at about the same time each evening.

The daily log below, from POTS Journey (part of Health Journey Labs), lists the core fields and why each one helps.

In POTS Journey, the Daily check-in holds these fields in one guided pass, so most of this table takes a minute or two.

How to track POTS heart rate and upright symptoms

NINDS describes a fast heartbeat as the classic symptom of POTS. It notes that heart rate may increase by more than 30 beats per minute or exceed 120 beats per minute within 10 minutes of standing, and usually improves on lying down again (NINDS). A consistent routine makes home readings more useful to your clinician.

For heart rate and upright symptoms, note:

• heart rate lying down and after standing, taken the same way each time;
• time of day and what you had been doing;
• dizziness, palpitations, and vision changes on standing;
• any faint or near-faint, with what came before it;
• how long it took to settle after sitting or lying down.

Tip: keep the measuring routine the same, such as the same device, position, and time. The NHS notes a GP may check blood pressure and heart rate before and after you stand, so steady home notes are easier to compare with clinic readings.

With POTS Journey, the heart-rate tracker records resting and standing heart rate (bpm) with your position and minutes standing, and the Flare Tracker marks a near-faint or clearly worse day. A few weeks of entries make it clear which situations, such as heat or long standing, come before larger spikes.

How to log fluids, meals, heat, and other POTS triggers

The NHS lists several things that can make symptoms worse: getting too hot, standing or sitting upright for long periods, eating, especially carbohydrates, not drinking enough fluids, drinking alcohol, resting too much, exercise, and being on your period (NHS). NINDS notes some people report more episodes right before their periods (NINDS). Logging these next to scores shows which matter most for you.

The trigger checklist below uses factors named by the NHS and NINDS.

For heat in more detail, see why heat makes POTS days harder. With POTS Journey, the Food Tracker holds meals, caffeine, alcohol, and fluid timing, and the Period Tracker keeps cycle dates.

How to track activity, rest, sleep, and brain fog with POTS

The NHS suggests gentle exercise such as walking, pilates, and swimming, while being careful and stopping if symptoms start, and lists resting too much and exercise among things that can worsen symptoms (NHS). NINDS notes that physical activity that slowly builds in intensity can improve tolerance to standing, while some people have exercise intolerance, so this approach suits only some people (NINDS).

For activity, sleep, and fog, record:

• activity type, position, such as lying or seated, and duration;
• how you felt during, after, and the next day;
• sleep hours and quality on a 0–10 scale;
• brain fog on a 0–10 scale, with one example;
• whether you raised the head of your bed or used other advice from your team.

Discuss any exercise plan with your clinicians before starting. Tip: log next-day recovery, not only the session, since a delayed crash is easy to miss in same-day notes.

With POTS Journey, Weekly Goals can hold one pacing aim, and the Daily Journal records how you felt after each session, including by voice recording on foggy days. Over a few weeks you can see whether a slow build-up came before better standing tolerance.

How to track POTS tests, medicines, and compression

The NHS describes an active stand test, blood tests, an ECG, and specialist tests such as a tilt table test and heart rate monitoring. It notes that treatment may start with lifestyle changes such as more fluids, smaller meals with fewer carbohydrates, and compression clothing, and that medicines may include fludrocortisone or beta blockers, sometimes trying several (NHS). NINDS notes some medicines may cause or worsen POTS symptoms, and advises consulting a provider before starting or stopping any (NINDS).

For each test and treatment, record:

• test dates, results, and what your clinician said;
• each medicine, dose, start date, and who prescribed it;
• missed doses, with the reason;
• side effects and when they began;
• compression use and fluid or salt plans your clinician set.

Write down any concern about side effects with its date, and raise it with your prescriber before making changes. For test dates in more detail, see how to track POTS labs next to heart rate and standing weeks.

With POTS Journey, My Meds keeps medicines with timing, the Daily check-in marks salt intake and dehydration, and My Labs holds test dates.

How to bring a POTS log to an appointment

NINDS notes that diagnosing POTS can be challenging and may involve seeing specialists such as cardiologists or neurologists (NINDS). With several clinicians, a clear summary helps each one catch up quickly. NINDS also notes that anxiety, depression, and sleep problems can come with ongoing POTS, so mood and sleep belong in the summary too (NINDS).

A short summary for the visit can include:

• average dizziness, fatigue, and fog scores per week;
• heart rate notes lying and standing, with dates;
• faints or near-faints, and what came before them;
• the triggers that showed up most often;
• current medicines with start dates and side effects;
• your top three questions, in order.

Tip: add one line on daily function, such as standing tolerance, work hours, or chores managed. The NHS notes POTS can have a big impact on everyday life for some people, and a function line makes that impact concrete.

With POTS Journey, My Care Team stores each clinician and visit notes. The Doctor Report gives you two things: the Appointment Planning Report, a list of questions to prepare before the visit, and Generate Report, a dated summary of your recent progress to show a doctor saved in My Care Team.

How POTS Journey can help

A notebook can hold daily entries. The harder step is relating them over weeks: seeing whether symptoms follow heat, meals, or short nights, whether fluids change upright days, or whether a new medicine is reducing hard days. For a comparison of options, see the best POTS apps in 2026.

POTS Journey is a personal POTS tracker from Health Journey Labs on the App Store and Google Play. It records upright symptoms, heart rate, fatigue, fog, and flares together with fluids, meals, heat, sleep, tests, and medicines. Its insights show which habits and treatments come before easier or harder weeks. Learn explains the condition in plain words, and the AI companions, such as Clara, answer questions when a new symptom or result is hard to read. Below is what you can use and how each part helps:

• My Meds — Medicine names and timing, such as beta blockers, midodrine, or fludrocortisone, so you can see how a start date lines up with standing tolerance.
• Daily check-in — A short guided pass across symptoms, mood, nutrition, sleep, exercise, meds, and external factors, including dizziness, heart rate spikes, salt intake, dehydration, heat, and fog.
• Flare Tracker — Mark a day clearly worse than your usual hard week, with a category, intensity, and duration, so insights can separate a one-off spike from a pattern.
• Daily Journal — Freer notes, including voice when fog or fatigue makes typing hard, such as how you felt after exercise or notes after a visit.
• Weekly Goals — Set one small aim, such as a glass of water before getting up or a short recumbent workout three times a week, and see whether it held.
• Food Tracker — Meal or drink lines when meals, caffeine, alcohol, or salt and fluid timing come with worse upright or fog days.
• AI companions — Clara and specialist companions already see your logged history, which helps with visit wording or pacing ideas.
• Doctor Report — Two views: the Appointment Planning Report, a list of questions to prepare before a visit, and Generate Report, a dated summary of your recent progress to show a doctor saved in My Care Team.
• My Labs — Result dates for tilt-table notes, blood counts, iron, thyroid, or other tests, so each result sits next to how you felt that month.
• My Care Team — A profile for each clinician, plus visit notes used before, during, and after appointments.
• Learn — Short education topics on standing tolerance, exercise done lying or sitting down (recumbent exercise), pacing, and visit preparation.
• Weight Tracker — Weight entries when weight or fluid shifts are part of what you and your clinician are watching.
• Period Tracker — Cycle dates and flow, so insights can relate cycle timing to upright symptoms or heat weeks.
• My Assessments — Structured check-ins that give insights more context about you across weeks.

Everything you log builds one history. Guided forms include the key questions, and you can add custom symptoms when you need your own labels. POTS Journey is free to download.
