Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation of 'low' as 'низкий' implying 'bad quality'. It's a medical measurement term. The direct translation 'низкое кровяное давление' is correct. Beware of false friends with 'pressure' (давление) which can also mean 'stress' in Russian, but here is purely physiological.
Common Mistakes
- Using 'low blood pressure' as a verb (e.g., 'I low blood pressured yesterday' - incorrect). Confusing it with 'low blood sugar'. Using 'hypo-' prefix incorrectly (it means 'under', not 'bad').

FAQ
Frequently Asked Questions
It can be if it causes symptoms like fainting, dizziness, or shock, or if it is a sign of an underlying serious condition. Chronic, asymptomatic low blood pressure is often not dangerous and may even be associated with longevity.
'Hypotension' is the formal, technical medical term. 'Low blood pressure' is the common, layperson's term. They refer to the same condition, but 'hypotension' is used in clinical settings.
Treatment depends on the cause. If it's due to medication or dehydration, it can often be reversed. Primary (essential) hypotension may be managed with lifestyle changes (more fluids, salt, compression stockings) but is often a chronic trait rather than a 'curable' disease.
While definitions vary, a sustained reading of less than 90 mmHg systolic or 60 mmHg diastolic is generally considered low blood pressure. However, a doctor's diagnosis is essential, as 'normal' varies per individual.
