POTS Constipation and Bloating: What to Log

Updated 29 Oct 2026

With POTS, gut symptoms can get less attention than dizziness and heart rate. Constipation and bloating can still shape a day, and they are easier to discuss when you have dates and details.

This guide covers what to log for constipation and bloating with POTS: bowel changes, bloating and tummy pain, fluids and fiber, movement and toilet routine, medicines, and when to see a GP.

Why gut symptoms are worth logging with POTS

POTS Journey (part of Health Journey Labs) reviewed the NHS guidance. The NHS lists problems with your stomach or digestion, such as feeling sick, being sick, diarrhea, constipation, bloating, and tummy pain, among the other symptoms you may get with PoTS (NHS PoTS guidance). It notes that PoTS affects everyone differently, that symptoms may be worse in the morning, and that they may change from day to day (NHS PoTS guidance).

The NHS lists not drinking enough fluids and resting too much among the things that can make PoTS symptoms worse (NHS PoTS guidance). Its constipation page lists not drinking enough fluids and not moving enough among the most common causes of constipation (NHS constipation guidance). So the same days can matter for both.

A dated log lets you see whether gut symptoms follow the low-fluid, low-movement days, or come on their own.

For sickness on upright days, see what to log on POTS nausea upright days.

In POTS Journey, the Daily check-in keeps gut symptoms on the same day as upright symptoms.

What to log about bowel changes

The NHS says it is likely to be constipation if you have not had a poo at least 3 times during the last week or you are pooing less often than usual; the poo is unusually large or small and is dry, hard, or lumpy; you are straining or in pain when you have a poo; or you feel like you have not fully emptied your bowels (NHS constipation guidance). It adds you may also have a stomach ache and feel bloated or sick (NHS constipation guidance).

Log each bowel movement with the date, a short note on how hard it was, and whether you strained or felt you had not finished. Note the days with none.

After a week, you can count how many times you went, which answers the first NHS question directly. Bring that count, not a guess.

In POTS Journey, the Daily Journal records bowel notes in your own words.

What to log about bloating and tummy pain

The NHS lists bloating and tummy pain among the digestion problems that can come with PoTS (NHS PoTS guidance), and its constipation page says you may feel bloated or sick with constipation (NHS constipation guidance). It also lists eating, especially carbohydrates like white bread, pasta, and rice, among the things that can make PoTS symptoms worse (NHS PoTS guidance).

Log when bloating or tummy pain started, how long it lasted, and what you had eaten in the hours before. Note whether it came with other PoTS symptoms, such as dizziness after the same meal.

Over a few weeks, the log can show whether bloating follows certain meals, comes with constipation, or arrives on its own.

For meal days, see what to log on POTS post-meal crash days.

In POTS Journey, the Food Tracker records meals beside how you felt afterwards.

What to log about fluids and fiber

The NHS suggests changes to make poo softer and easier to pass: eat a healthy balanced diet and include fruits that contain sorbitol, such as apples, apricots, grapes, raisins, raspberries, and strawberries; drink plenty of water and other fluids and avoid alcohol; gradually increase the fiber in your diet; and add some wheat bran, oats, or linseed (NHS constipation guidance).

Fluids also matter for PoTS itself, since the NHS lists not drinking enough fluids and drinking alcohol among the things that can make PoTS symptoms worse (NHS PoTS guidance).

Log drinks through the day and the fiber foods you had. Add fiber gradually, as the NHS says, and note any change in bloating as you do. The NHS notes you may see a difference within a few days, and sometimes it takes a few weeks (NHS, Constipation).

For fluid days, see what to log on POTS fluid and salt days.

In POTS Journey, Weekly Goals sets one small aim, such as one extra fiber food a day, and shows whether it held.

What to log about movement and toilet routine

The NHS lists not moving enough and spending long periods sitting or lying down, being less active, often ignoring the urge to go, and changing your diet or daily routine among the common causes of constipation (NHS constipation guidance).

It suggests keeping to a regular time and place and giving yourself plenty of time to use the toilet, not delaying when you feel the urge, resting your feet on a low stool and raising your knees above your hips if possible, and notes a daily walk or run can help you poo more regularly (NHS constipation guidance).

With PoTS, movement can be hard on some days, and the NHS lists both resting too much and exercise among things that can make symptoms worse (NHS PoTS guidance). So log what movement you managed and how upright symptoms felt, and plan any change with your team.

In POTS Journey, the Flare Tracker marks heavy days, so you can see whether low-movement weeks match gut changes.

What to log about medicines and when to see a GP

The NHS lists a side effect of medicine among causes of constipation, and says to speak to a pharmacist if diet and lifestyle changes are not helping, since they can suggest a laxative, adding that most laxatives work within 3 days and should only be used for a short time (NHS constipation guidance).

The NHS advises seeing a GP if you are constipated and treatment is not helping, are regularly constipated or bloated, have blood in your poo, have lost weight without trying, are constipated and feel tired all the time, are taking medicine that is causing constipation, notice sudden changes in your bowel habits, or have tummy pain (NHS constipation guidance). It also says to speak to the GP before you stop taking any prescribed medicine (NHS constipation guidance).

Log every medicine with its start date, including any laxative, so a change in your bowels can be lined up against it.

If a new medicine started in the same week as a bowel change, bring both dates to the GP or pharmacist and ask about it, and keep taking prescribed medicine unless they advise otherwise.

In POTS Journey, My Meds keeps each medicine with its start date.

How POTS Journey can help

A single uncomfortable day is easy to forget. The harder part is keeping bowel changes, bloating, fluids, meals, and upright days in one dated record, so your team can see how they connect.

POTS Journey is a personal POTS tracker from Health Journey Labs on the App Store and Google Play. It records symptoms, heart rate notes, medicines, and tests in one dated history. For a side-by-side look at POTS trackers, see the best POTS apps in 2026. 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 you can tell 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 you can line up cycle timing with upright symptoms or heat weeks.
• My Assessments — Structured check-ins that add 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.
