How Can You Instantly Raise Low Blood Pressure?

To raise blood pressure quickly, eat salty foods, drink lots of fluids and wear compression stockings, advises Mayo Clinic. Obtain a prescription for medication that raises blood pressure.

Salt in the diet can cause a dramatic raise in blood pressure, but it is important to get physician approval before increasing salt in the diet. Excess salt can lead to heart failure, notes Mayo Clinic. By increasing fluid intake, blood volume is increased, which helps to raise blood pressure. Compression stockings can reduce pooling of blood in the legs and bring up blood pressure numbers. Medications such as the drug fludrocortisone can help to boost blood volume, and thus, blood pressure.
