How common are dehydration headaches?

Nearly everyone gets a headache from time to time. Headaches are the most common type of pain. They result from many different conditions, disorders and diseases, including dehydration.

Healthcare providers aren’t sure how many people get dehydration headaches. In the United States, most people don’t get enough fluids, either from their food or by drinking water. Lack of fluids can lead to dehydration, which causes headaches. Babies, young children and older adults have a higher risk of dehydration. People with certain health conditions (such as diabetes) also have an increased risk.
