Why do calcium channel blockers cause headaches?

If you’re currently struggling with headaches, despite being on medication for hypertension, then welcome to the club! Did you know that calcium channel blockers (CCBs) are a common culprit of throbbing and pulsating headaches? While some may find it surprising, there’s actually a pretty simple explanation behind why CCBs cause this discomfort. In this article, we’ll be breaking down just how CCBs function in our bodies and delve into their potential side effects. So buckle up and let’s get started!

The Basics: What Exactly Are Calcium Channel Blockers?

Before we dive into the nitty-gritty, let’s get acquainted with what exactly CCBs are. As the name suggests, these medications work by blocking certain channels called calcium channels in the body.

How Do They Function?

Calcium is vital for healthy muscle contraction – including your heart muscles – as well as nerve transmission throughout our bodies. However, too much can lead to increased blood pressure or irregular heartbeat (aka arrhythmia). This is where CCBs come in handy; they relaxes smooth muscles around arteries which limits the amount of calcium entering cells thereby reducing high blood pressure

As such,they’re commonly used to treat hypertension by relaxing muscles around your arteries which results in more space within them allowing proper blood flow–nifty right?

So if you have hypertension — or an abnormal heart rhythm condition — then you’ve probably been prescribed one of these meds at some point.

The Mystery Unveiled: The Link Between Calcium Channels And Headaches

For those taking these medications for extended periods, it’s not uncommon to suffer from recurring headaches that often differ from typical migraines.

Although it remains somewhat unclear why calcium-channel blockers can trigger headaches even after prolonged use,the most widely accepted theory suggest:

Blood Vessel Dilation

CCBs dilate blood vessels by relaxing smooth muscles, which results in more blood to flow smoothly. However, with increased dilation often comes decreased levels of pressure within your head cavity which may trigger a headache.

Chemical Imbalances

Another theory is that blocking calcium channels can cause imbalances within the production and utilization of neurotransmitters; chemicals used for nerve signaling. Any changes to these systems could be enough to induce headaches

Impact on Blood Flow Velocity

The final suggestion is that CCBs might affect the distribution of blood throughout our brains. Indeed, studies have shown noticeable alterations in cerebral-blood-flow velocity following administration/ingestion over prolonged periods–resulting in unwanted migraines.

Other Potential Side Effects Of Calcium Channel Blockers

It’s paramount we mention as well other possible side effects of taking such medication apart from headaches:

  • Dizziness: Given that CCBs relax muscle around arteries resulting to low BP –you may experience lightheadedness or dizziness post dosage ingestion.

  • Flushing: Your body metabolizes all meds differently – but it’s not entirely unheard of some people experiencing blushing or flushed skin after ingesting CCBs.

  • Constipation: Some people utilizing these blockers often grapple with constipation as food moves slowly along the digestive tract due to relaxed smooth mucus surrounding their intestines.

As mentioned earlier, each drug will come with its unique set of side-effects listed out on packaging when dispensed.prescription

So What Can You Do About It?

If you’re experiencing excruciating headaches while being medicated Onset [with] any or short-term use: one thing you should do naturally would be visiting your physician who will determine if it’s indeed caused by drug intake/will usually discuss switching medications/alter dosages/offer alternatives.

Furthermore,some individuals find it helpful adjusting their sleeping habits (longer hours & reduced stress) and consuming healthier, vitamin-rich meals. Additionally, drinking plenty of water throughout the day may also alleviate induced headaches?

Conclusion

In summary, while CCBS are a valuable medication for treating hypertension – indeed preventing more severe heart-related conditions- they may have potential side effects such as recurring headaches. Several theories have been suggested on why this happens , including blood vessel dilation or cerebral-blood-flow velocity.

Thank you for reading through our brief analysis piece! We hope it shed some light on just how much imbalances within calcium channels in our bodies can potentially impact us – even though they might help cure many ailments.
