Hypotension is defined as low blood pressure. This condition occurs when the blood pressure reading is significantly lower than the normal range, which typically is around 120/80 mmHg for adults. Hypotension can lead to insufficient blood flow to organs, resulting in symptoms such as dizziness, fainting, and in severe cases, shock.

Understanding blood pressure readings is crucial. The top number, or systolic pressure, measures the pressure in the arteries when the heart beats, while the bottom number, or diastolic pressure, measures the pressure in the arteries when the heart rests between beats. A reading lower than 90/60 mmHg is generally considered indicative of hypotension.

Normal blood pressure indicates healthy cardiovascular function, and high blood pressure, known as hypertension, signifies a different range of health issues. Rapid heart rate alone does not define low blood pressure; it can occur under various conditions, including stress and anxiety, but does not correlate directly with hypotension.
