70/66 blood pressure: Everything you need to know
A blood pressure of 70/66 is considered
low blood pressure.
Low blood pressure, also known as hypotension, occurs when the systolic number is less than 90 or the diastolic number is less than 60. Hypotension generally isn't considered a medical issue unless it causes symptoms (such as dizziness, light-headedness, or fainting) or unless it drops suddenly.

Symptoms associated with a 70/66 blood pressure
Because this blood pressure is considered low, you might experience the following symptoms:
- Dizziness or lightheadedness
- Blurred or fading vision
- Lack of concentration
However, many people have what looks like low blood pressure but have no symptoms at all. For example, elite athletes or endurance runners may have extremely low blood pressure due to their intense physical training and overall cardiovascular health. It's also possible to just have low blood pressure naturally.
If you have any of the symptoms above or just have questions about your blood pressure, make an appointment to speak to your doctor.
Lifestyle changes for a blood pressure of 70/66
Because this blood pressure reading indicates low blood pressure, you may want to ask your doctor about lifestyle changes that increase your blood pressure. Here are a few ways you can increase your blood pressure to a more normal range without medication:
- Eat more salt: While the majority of people need to lower their salt intake, people with low blood pressure can sometimes increase their salt intake to raise their blood pressure to healthy levels.
- Drink more water: Drinking water increases blood volume and helps prevent dehydration, both of which can help raise your blood pressure.
- Wear compression stockings: Compression stockings can reduce the pooling of blood in your legs and therefore raise your blood pressure.
Medications for a blood pressure of 70/66
If you haven't been successful raising low blood pressure with the lifestyle modifications listed above, you may want to ask your doctor if there are any medications that can help. The following medications are commonly prescribed for low blood pressure:
- Fludrocortisone: Fludrocortisone is a corticosteroid often prescribed to treat low blood pressure that occurs when you go from a sitting or lying position to standing position. It works by increasing blood volume.
- Midodrine: Midodrine, also known as Orvaten, raises standing blood pressure in people with chronic orthostatic blood pressure. It prevents blood vessels from expanding, which raises blood pressure.
