High blood pressure can burst or block arteries that supply blood and oxygen to the brain, causing a stroke. Brain cells die during a stroke because they do not get enough oxygen. Stroke can cause serious disabilities in speech, movement, and other basic activities, and a stroke can kill you.

If you have a low diastolic pressure, it means you have a low coronary artery pressure, and that means your heart is going to lack blood and oxygen. That is what we call ischemia, and that kind of chronic, low-level ischemia may weaken the heart over time and potentially lead to heart failure.

What happens when high blood pressure and poor circulation continue? This reduces much needed oxygen flow to the cells through the veins and capillaries, which regenerates and heals the cells. Many times the kidneys react to continue high blood pressure by causing the body to retain water and sodium.

The effects of low blood pressure are several and chronic hypotension may result in the blood being unable to transport enough oxygen to the brain or to other parts of the body causing numbness, and in severe cases, stroke, loss of consciousness, concussion, coma, shock or death.

Blood carries oxygen to the cells throughout your body to keep them healthy. Hypoxemia can cause mild problems such as headaches and shortness of breath. In severe cases, it can interfere with heart and brain function. Hypoxemia that causes low oxygen levels in your body's tissues is called hypoxia.

A blood oxygen level below 60 mm Hg is considered low and may require oxygen supplementation, depending on a doctor's decision and the individual case. When blood oxygen level is too low compared to the average level of a healthy person, it can be a sign of a condition known as hypoxemia.

Causes of hypotension If the measurement drops 30mmHg below the person's usual blood pressure, this is considered to be hypotension. Low blood pressure has many different causes including: Emotional stress, fear, insecurity or pain (the most common causes of fainting) Dehydration, which reduces blood volume.

Long-term high blood pressure can potentially lead to low pulse. High blood pressure can cause your heart's tissues to remodel. For example, the tissue may become thicker in an attempt to beat harder.

Hypoxemia occurs when levels of oxygen in the blood are lower than normal. If blood oxygen levels are too low, your body may not work properly. Blood carries oxygen to the cells throughout your body to keep them healthy. Hypoxemia can cause mild problems such as headaches and shortness of breath.

The inability to get enough oxygen into the lung raises the risk for developing hypoxia. Hypoxia is a condition where not enough oxygen makes it to the cells and tissues in the body. This can happen even though blood flow is normal. Hypoxia can lead to many serious, sometimes life-threatening complications.

Although low blood pressure is generally the cause of shock, blood pressure may not be low in the early stages of shock. Also, blood pressure can be low in people who do not have shock. The medical disorder of shock has nothing to do with the “shock” that people feel from a sudden emotional stress.

Among them? Pulmonary hypertension — or high blood pressure in the loop of vessels connecting the heart and lungs. Shortness of breath is a telltale sign of the condition.

Some heart conditions that can lead to low blood pressure include extremely low heart rate (bradycardia), heart valve problems, heart attack and heart failure. Endocrine problems.
