Does Vomiting Cause Blood Pressure to Rise?


Vomiting itself can cause a temporary increase in blood pressure. During vomiting, there is a forceful contraction of abdominal muscles and the diaphragm, which can lead to a transient rise in blood pressure. This increase is usually short-lived and is part of the body’s response to the physical exertion associated with vomiting.

However, if vomiting is severe, persistent, or accompanied by other symptoms, it can lead to complications that may affect blood pressure. For example, dehydration due to fluid loss during vomiting can cause a drop in blood volume, leading to a potential decrease in blood pressure.

It’s essential to note that individual responses can vary, and factors such as the underlying cause of vomiting, overall health, and hydration status can influence the impact on blood pressure. If you are experiencing persistent or severe vomiting, it’s important to seek medical attention to address the underlying cause and manage any potential complications. Persistent changes in blood pressure should be evaluated by a healthcare professional to determine the appropriate course of action.
