Low blood pressure, or hypotension, is generally not a concern and requires no treatment in healthy people, according to WebMD. Low blood pressure can signify a more ominous underlying health problem, particularly in the elderly, since it can cause inadequate flow of blood to the vital organs and brain.
Treatment of hypotension may require treatment of an underlying condition, such as diabetes, heart failure, hypothyroidism or dehydration. In some cases, hypotension is brought on by medication, and alteration of dosage can sometimes remedy the problem. Wearing compression stockings, increasing sodium intake under a physician's observation, and increasing water intake can all raise blood pressure, according to Mayo Clinic. There are also some medications that restrict the expansion capacity of the blood vessels to cause an artificial rise in blood pressure.
