In the first years of disease, fainting is very rare, but in the later years, it can happen. This is usually the result of quick and excessive blood pressure drop after standing up from a chair or out of bed, or after a period of standing upright. Many patients already feel dizzy, but fainting can also occur quite suddenly. Fainting is not only annoying, but also dangerous because it can lead to fall or fall-related injuries. The cause is partly due to the disease itself, and partly to the medication that people use. Part of the approach to the problem is therefore a critical evaluation of the medication schedule by the treating physician.
