What can trigger headaches during pregnancy?

Caffeine withdrawal is a well-recognized trigger for headaches during pregnancy. Many pregnant individuals may reduce or eliminate their caffeine intake due to concerns about its effects on the developing fetus. Abruptly stopping caffeine can lead to withdrawal symptoms, including headaches. This is particularly relevant for those who were regular caffeine consumers before pregnancy, as their bodies may have adapted to it.

While dehydration, lack of sleep, and excessive screen time can also contribute to headaches generally, caffeine withdrawal specifically links to a physiological reaction that occurs when the body no longer receives a substance to which it has become accustomed. Understanding this connection can help pregnant individuals manage their caffeine consumption effectively and anticipate possible withdrawal symptoms.
