What is the outlook for people with dehydration headaches?

Most dehydration headaches get better after drinking water and taking it easy for a while. If headaches keep happening, you may have chronic (long-term) dehydration. Chronic dehydration can lead to serious medical problems, including kidney stones and urinary tract infections (UTIs). People who aren’t hydrated have a higher risk of heat exhaustion and other heat illness.

Dehydration can trigger (cause) a migraine headache. If you get migraines, it’s essential to drink plenty of water. Staying hydrated may help you prevent a migraine attack.
