Hypotension can affect people of all ages. However, people in certain age groups are more likely to have certain types of hypotension.
Older adults are more likely to have orthostatic and postprandial hypotension. Children and young adults are more likely to have neurally mediated hypotension.
People who take certain medicines—such as diuretics ("water pills") or other high blood pressure medicines—are at increased risk for hypotension. Certain conditions also increase the risk for hypotension. Examples include central nervous system disorders (such as Parkinson's disease) and some heart conditions.
Other risk factors for hypotension include being immobile (not being able to move around very much) for long periods, being out in the heat for a long time, and pregnancy. Hypotension during pregnancy is normal and usually goes away after birth.
