Orthostatic intolerance describes difficulty with being upright; POTS is a particular syndrome assessed using symptoms and clinical measurements. Dysautonomia is a broader term. Do not treat the words as interchangeable diagnoses.
Separate a description from a diagnosis
Johns Hopkins describes POTS as a form of orthostatic intolerance involving an abnormal heart-rate response to standing with relevant symptoms. Its clinical information also places POTS within disorders of autonomic function. These relationships do not mean everyone who feels unwell standing has POTS.
The NHS explains that assessment can include heart rate and blood pressure before and after standing, with further investigations as needed. A watch graph or one home reading is not the complete assessment. Other explanations need consideration by a healthcare professional.
Read the wording in your record carefully
A letter may say “symptoms of orthostatic intolerance,” “possible POTS” or a confirmed diagnosis. Preserve qualifiers such as possible, suspected or under investigation. Removing them when copying a record can change its meaning.
If different letters use different terms, ask whether they refer to the same observation, a provisional assessment or an updated conclusion. Do not resolve the discrepancy by selecting the more specific-sounding label.
| Term | Question to ask |
|---|---|
| Orthostatic intolerance | What does this describe in my case? |
| POTS | Has this been diagnosed or is it being considered? |
| Dysautonomia | Which autonomic problem does the letter mean? |
| Investigation result | What did the test establish, and what remains uncertain? |
| Next step | What follow-up or instructions apply to me? |
Bring ordinary observations without provoking symptoms
Describe activities during which symptoms happened naturally, such as standing in a queue, and what you noticed. Include measurements only when they were obtained appropriately under your care instructions. Do not perform repeated standing challenges or push through faintness to prove a pattern.
If you have fainted or developed new or concerning symptoms, seek appropriate medical assessment. For emergency symptoms such as chest pain or severe breathing difficulty, use emergency services rather than working through a terminology guide.
Illustrative appointment question: “My letter says orthostatic intolerance, while an earlier note says possible POTS. Could you explain what is confirmed, what is still being investigated and what information you want from me?” This keeps the record’s uncertainty intact.
Leave with an explanation you can repeat
Ask the clinician to explain the diagnosis or working assessment in ordinary language. Note which symptoms or tests informed it and what the follow-up plan is. You can ask for a correction if a report contains a factual error, such as an incorrect date or medicine list.
Our appointment notes PDF can hold these questions. The context-record guide explains a practical diary. Ballast records observations; it does not establish POTS or determine a salt, fluid or exercise prescription. Follow your own clinical plan rather than a plan inferred from a label.
