Hyper - higher than normal Hypo - lower than normal
"Hypo" in biology usually refers to something that is below normal or beneath a certain threshold. For example, hypoglycemia refers to low blood sugar levels, while hypotension refers to low blood pressure.
The prefixes "sub-" and "hypo-" can indicate slowness, such as in words like "subside" and "hypotension."
when a person is hyper it means high so it is another meaning of high blood pressure This is actually incorrect. Hypertension means high blood pressure. You are asking about hypotension (different word). The "hypo-" prefix means "low" or "under" (as a hypodermic needle goes under the skin). Hypotension is low blood pressure, the opposite of high.
Low blood pressure.
The prefix hypo generally means below or under. It is commonly used in anatomy and medicine. Some examples of such words are- hypodermic, hypotension, hypotensive, hypothyroidism and hyposulphate.Hypothermia is under temperature.
Dehydration.
Abnormally low Blood Pressure is called "Hypotension"(Hypo-= Below, beneath, under, less than normal, deficient, in the lowest state of; Tension= to strain or stretch.)Blood pressure is the force(strain) on the blood vessels' walls. Thus, Hypotension is the less than normal strain on the walls of the blood vessels.
regular/ often/ constant high blood pressure
This low level can be a cause of hypotension.
The prefix "hypo-" means below, beneath, or deficient, often used to indicate a lower quantity or intensity.
The Greek prefix "hypo-" has several meanings: under, below, less than, smaller, etc.
In the context of hypotension, orthostatic hypotension is the same as postural hypotension.
