Where Is Blood Pressure The Lowest?
Knowing facts about your blood pressure is vital in maintaining your health. For this post I will answer the question: Where is blood pressure the lowest?
The answer to this question will help you in managing your blood pressure because when not managed, you can become hypertensive.
But first, what is blood pressure (BP)?
What is Blood Pressure?
Blood pressure is the pressure exerted by blood as it flows into the blood vessels. The BP is measured using a sphygmomanometer and a stethoscope.
The normal blood pressure is 120/80, with the Upper Normal Limit as 140/90. The numerator (120) is called the systolic pressure, which results when the ventricles contract blood into the artery. On the other hand, the diastolic pressure is the denominator (80), when the blood vessels return to their normal sizes.
However, blood pressure varies depending on the person’s existing health condition. When you have high blood pressure (HBP) or hypertension (HTN), the blood pressure goes beyond 140/90. This can be caused by the listed conditions below.
- Sedentary life style
- Genetics (essential hypertension)
- Drugs for colds and those containing pseudoephedrine and decongestants
- Constant salty diet
- Any condition that can cause the vasoconstriction (tightening) of blood vessels
In contrast, blood pressure is decreased in hypotension. This is a condition when the blood pressure goes below 90/60. This can be caused by the listed conditions below:
- Heart diseases
- Loss of blood volume
- Severe anemia
- Over-dosage of anti-hypertensive drugs
- Any condition thatcan cause vasodilation (widening) of blood vessels
- Blurry vision
- Muscle weakness
- Stomach pain
- Chest pain
- Syncope or fainting
- Polydipsia (excessive thirst)

Now that you know some basic facts about your blood pressure, you would know what to look for when your blood pressure is abnormal.
Going back to the main question, here’s the answer.
Where is Blood Pressure the Lowest?
The heart is the primary source of blood; thus, the pressure starts the strongest from the portion right after the heart. The oxygenated blood that the heart pumps into the arteries has the highest pressure because blood comes directly from the heart.
As the blood continuous to travel along the arteries and into the capillaries, the blood pressure is reduced gradually.
This is because the blood vessel wall becomes smaller as it travels to the extremities of your body.
When this blood goes into the veins, the blood pressure becomes the lowest. Hence, it’s in the veins that the blood pressure is the lowest.
Afterwards, the veins bring back the blood to the heart, where the cycle begins again.
Obviously, you would not want to be hypotensive or hypertensive. Here are tips on how you can maintain a normal blood pressure.
How to Maintain a Normal Blood Pressure?
1. Avoid Salty and Preserved Foods
Salt can increase your blood pressure because of its role in water-electrolyte balance. Preserved foods contain lots of salt too.
2. Avoid Bad Fats
Bad fats include meat fat. But take note that not all fats are bad. There are also good fats that you can eat, such as vegetable and fish fat. Too much bad fat can result to atherosclerosis or hypertriglyceridemia.
3. Exercise Daily
Blood pressure can increase due to fat deposits in your blood vessels (atherosclerosis). These fat plaques can be flushed out when you exercise because blood circulation is enhanced.
4. Avoid Alcohol and Caffeine
Alcohol has the propensity to increase your blood pressure, so it will aggravate your condition, if you’re already hypertensive; while caffeine can cause palpitations that could worsen your HTN.
5. Avoid Drugs with Pseudoephedrine and Decongestants
Decongestants constrict blood vessels, which can result to hypertension.
I have answered the question: Where is blood pressure the lowest?
The answer is: The blood pressure is lowest in the veins.
Knowing this fact, you can utilize it to protect your body well. You would rather have a vein injured than an artery because blood would flow slower in the vein that in the artery. This is because the pressure of blood is lowest in the veins.
