Treatment Options for Unexplained Fainting

Fainting (Unexplained)

Medication, or even simple lifestyle changes, can often prevent fainting. If your doctor suspects a more serious, heart-related cause, monitoring your heart’s rhythm over time may help your doctor determine the right treatment for you.

Lifestyle Changes

Lifestyle changes may include:

  • Avoiding potential triggers like hot environments, prolonged standing, dehydration, and certain medications.
  • Consuming adequate fluid.
  • Wearing support garments or compression socks to improve your circulation.
  • Standing up slowly when changing positions from sitting to standing.
  • Making changes to your diet, such as eating small, more frequent meals; increasing salt, fluid and potassium intake; and avoiding caffeine and alcohol.
  • Elevating the head of your bed while sleeping by using extra pillows or placing risers under the legs of the head of the bed.

Treatment With Medication

If you continue to have fainting spells after making some simple lifestyle changes, your doctor may prescribe a medication. It is helpful to determine the cause of the fainting in order to recommend the most appropriate medicine for your condition.

Treatment if Fainting Is Heart-Related

If your doctor suspects that your fainting is from a heart-related cause such as an abnormal heart rhythm, your doctor may prescribe additional testing or heart monitoring to help determine the cause. An insertable cardiac monitor (ICM) may help your doctor determine if an abnormal heart rhythm is the cause of your fainting. This option may be more applicable if you have had more than one fainting spell, and they seem to occur infrequently or over long periods of time. Once the cause of the fainting has been determined, treatment options may include a lifestyle change, medication, an implantable device (such as a pacemaker or implantable defibrillator) or other options. Your doctor will decide on the best treatment based on your diagnosis.
