Czy poranna kawa może nasilać rwę kulszową? Lekarz wyjaśnia

Can morning coffee worsen sciatica and back pain? Claims are increasingly appearing online that caffeine raises cortisol, disrupts adrenal function, increases inflammation, and may worsen sciatica symptoms. It's also said that by blocking adenosine, coffee overstimulates the nervous system. In this article, I explain: – whether coffee actually affects cortisol and the hypothalamic-pituitary-adrenal axis, – what adenosine is and why caffeine blocks its receptors, – whether blocking adenosine can increase heart rate and nerve excitability, – whether caffeine can exacerbate inflammation and radicular pain, – whether coffee causes dehydration of intervertebral discs, – whether tightness in the piriformis muscle is related to caffeine. Adenosine is the body's natural "brake"—it affects the nervous system and the heart. In medical practice, we even use it to terminate paroxysmal supraventricular tachycardia. Therefore, it's important to understand how caffeine works before we start fearing it. As a physician who has been treating pain and sciatica for many years, I've been separating facts from myths. No scaremongering. No sensationalism. Just physiology, clinical research, and practice. If you struggle with low back pain, disc herniation, or sciatica, this material will help you understand whether you really need to give up coffee. Remember: a frightened person is easily manipulated. Make decisions based on knowledge, not fear.
