A common side effect in Parkinson's and in the medications used to treat your symptoms. Low blood pressure can cause dizziness, disorientation and in severe cases can cause you to collapse. Managing your blood pressure can have a significant effect on your falls risk. You should always discuss with your GP if blood pressure is an issue, as medical management may be able to improve this. If this is not possible some simple tips to reduce your risk include:

1. Drink plenty of water. Drinking fluids helps to maintain your blood volume, which keeps blood pressure at a suitable level. Try increasing your fluid intake, while avoiding dehydrating variations such as alcohol or excess coffee, to see if that helps.
2. Give yourself a second - changing positions from lying to sitting, and from sitting to standing makes your blood pressure drop slightly, so if your blood pressure is already low this can cause dizziness. When getting out of bed or from  chair, sit for a few seconds to let your head adjust before standing. Then give yourself a few seconds to let your body adjust to standing before beginning to watch.

Having reduced vision will affect your orientation, and if you have poor balance on top of that, can increase your risk of falling. If you feel you are not happy with your eyesight, consider an opticians review to see if your vision can be aided.
