G52.2: Disorders of vagus nerve
The vagus nerve runs on both sides of the brain through the neck and through the chest to the abdomen. The vagus nerve is important for relaxation phases. For example, it can stimulate the digestion, make the heart beat more slowly, and decrease blood pressure. The vagus nerve is also important for some movements involved in swallowing and speaking. The vagus nerve also transfers various items of information, for example from the digestive organs, to the brain.
Damage to the vagus nerve can produce a range of different symptoms. For example, your voice may sound hoarse. You may have problems when swallowing. Damage of the vagus nerve on both sides can result in the person having great difficulty breathing.
