The first signs of lowered blood pressure is a bout of dizziness and nausea that can cause a person to lose consciousness. In such a situation, it becomes important to take up steps to raise their blood pressure quickly. The following are certain ways by which you can do that.
Drinking water. If possible, give her a sports drink. Sports drinks have several nutrients and minerals packed in her which replenish the lost nutrients and increase the lowered blood pressure.
Give her a snack that has a high content of salt in it. Salt is known to increase the volume of blood and thereby increase the blood pressure quickly.
Ask her to stand up and move around with the help of someone (if they're still feeling dizzy). Lying down for a long time or sitting in one position for a prolonged periods is known to lower blood pressure levels. Moving around will increase the blood circulation and thereby the blood pressure.
If you can procure compression stockings, make the patient wear these. These help to improve the circulation in the body and stop the pooling of blood in one area. Once the blood starts flowing freely, the blood pressure will increase automatically.
Feeding the patient herbs like rosemary, ginger, ginkgo biloba, ginseng and hawthorn, as well as Vitamin B and E supplements is known to increase the blood pressure quickly.
Alternating between hot and cold showers is known to help improve the blood circulation in the body.
