Risk factors

By Mayo Clinic staff

Low blood pressure (hypotension) can occur in anyone, though certain types of low blood pressure are more common depending on your age or other factors:

  • Age. Drops in blood pressure on standing or after eating occur primarily in adults older than 65. Orthostatic hypotension happens after standing up, while postprandial hypotension happens after eating a meal. Neurally mediated hypotension happens as a result of a miscommunication between the brain and heart. It primarily affects children and younger adults.
  • Medications. People who take certain medications, such as high blood pressure medications like alpha blockers, have a greater risk of low blood pressure. This is especially true for adults over age 80.
  • Certain diseases. Parkinson's disease, diabetes and some heart conditions put you at a greater risk of developing low blood pressure.
