Your Cyclospora Test Was Negative... So Why Do You Still Have Diarrhea? 🤔

Your Cyclospora test came back negative.

Great!

...except you're still having diarrhea.

So now what?

If you're like a lot of people, you're relieved that you don't have Cyclospora, but you're also frustrated because you still don't know why you're sick. And that's exactly what I want to talk about today.

A Negative Test Doesn't Mean Nothing Is Wrong 👨‍⚕️

I'm Dr. Stephen Wangen. I've been treating digestive disorders for over 25 years and founded the IBS Treatment Center in 2005, where we've helped more than 10,000 patients recover from chronic digestive problems.

Now you might think that if you don’t have IBS, then this doesn’t apply to you. But I don’t care if you have IBS. It’s a basically useless diagnosis anyway. What I care about is helping you solve diarrhea, and that’s what I’m going to talk about.

One of the biggest mistakes people make is assuming that a negative test means there's nothing wrong. It doesn't. It simply means you don't have that particular condition.

Think of It Like Your Car 🚗

Imagine taking your car to a mechanic because it won't start. The mechanic checks the battery. The battery is fine. Does that mean there's nothing wrong with the car? Of course not. It simply means the battery isn't the problem.

Medicine works the same way. Actually, it doesn’t. But it should work that way, right? And at my clinic, that’s exactly how it does work.

A negative Cyclospora test only tells you that Cyclospora isn't causing your symptoms. It doesn't tell you what is causing them.

There Are Many Possible Causes 🔍

There are many, many other things that can cause diarrhea. There are other parasites, bacterial infections, viruses, inflammatory diseases, food reactions, and digestive disorders that have nothing to do with an infection at all.

The real question isn't, "Do I have Cyclospora?" The real question is, "Why do I have diarrhea?" and, "How do I get my life back?" Those are the questions that we've been helping patients answer for decades.

We Keep Looking Until We Find the Answer 🧪

A lot of people come to us after they've already had a lot of testing. Often they've even had a colonoscopy and have been told everything looks normal. But they're still sick.

Our job is to keep looking until we find the reason, and we certainly don't stop with Cyclospora. We’ve tested every single patient for Cyclospora for over twenty years, so we know what to do when you don’t have Cyclospora. We test for ALL parasites, bacteria, viruses, and other gastrointestinal infections.

But we also recognize that many people with chronic diarrhea don't have an infection at all. They have something else that's been overlooked. That's why we don't focus on just one diagnosis. We focus on solving the problem.

Our Goal Is Simple 💙

Because at the end of the day, you don't really care whether your diagnosis is Cyclospora, Giardia, or whatever. You just want the diarrhea to stop, and you want your life back. And that’s what we want for you too.

So if your Cyclospora test was negative but you're still dealing with diarrhea, don't assume you've reached the end of the road. You are simply at the beginning of finding the real answer.

If you'd like our help, we've been treating patients via telemedicine since 2005, so we can work with you regardless of where you live. We even have a money back guarantee.

So if you have diarrhea and want to get your life back, give us a call at 206-264-1111. We’ll help you figure out the cause.

As always, take good care of your body. It's the only place you have to live. 🌱
