This article on phentermine and headaches is one of the more balanced overviews I’ve come across on the topic. It explains that although not everyone will get headaches, certain physiological changes triggered by appetite suppression can make them more likely for some users. I liked that it walks through how factors like hydration and nutrition interact with this effect. The language is practical and easy to follow, even if you’re not familiar with medical jargon. Definitely worth checking out if you’re curious about common experiences with this medication.
