All medications have side effects- read the side effects of aspirin.(Scary). Part of the problem being that the chemicals that work in things like plants is the only thing extracted, but God has formulated plants to have that which also combats the side effects contained within. Yes, you can take white birch instead of an aspirin but we have come so far away from using it that we don't know how much to take, etc. anymore. We have dumbed down in ways, advanced in other ways. We are not as advanced as we think. But I am glad for the modern meds there are and hopefully we won't kill off the things put here to help us before they are uncovered.

Why do heart medications sometimes cause symptoms similar to heart disease?

It's not just you—this is a really valid observation! Many heart medications work by changing how your heart and blood vessels function, which can sometimes create side effects that feel similar to heart symptoms.

For example, blood pressure medications like losartan work by relaxing blood vessels and reducing the workload on your heart. When blood vessels relax too much or blood pressure drops, you might feel dizzy when standing up. This isn't your heart disease getting worse—it's actually the medication doing its job, sometimes a bit too well.

Similarly, medications that slow your heart rate or reduce blood pressure can cause fatigue because your body is adjusting to working differently. These side effects often improve as your body adapts to the medication. Why might you be prescribed medication when your tests look normal?

Doctors sometimes prescribe heart medications preventively, especially if you have risk factors like high blood pressure, high cholesterol, or diabetes—even if you haven't had a heart attack or stroke yet. The goal is to protect your heart and blood vessels before damage occurs.

That said, if your monitoring shows everything is consistently normal and you're concerned about whether you still need the medication, that's absolutely worth discussing with your doctor. They can review your current risk factors and whether the medication is still necessary for your specific situation.

It's great that you're tracking your health so carefully—that data can really help guide these conversations!
