Cyclospora: What Most Doctors Won't Tell You About Chronic Diarrhea

Could Your Diarrhea Really Be Cyclospora?🦠

Cyclospora is all over the news right now. If you've suddenly developed diarrhea, stomach cramps, bloating, nausea, or fatigue, you may be wondering, "Could I have Cyclospora?"

The answer is yes. There is a significant outbreak happening right now, and many people are being infected through contaminated food. If you have diarrhea, you should get tested, and we ALWAYS do that.

But here's what almost nobody is talking about. What if your diarrhea isn't caused by Cyclospora? What else should you be doing? You still deserve to know what's causing it, and I’ll tell you exactly how we do that.

Why We Look Beyond the Diagnosis 👨‍⚕️

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

First off, I don’t care if you have IBS or not. Diagnosing IBS is not what we do. Finding the cause and solving diarrhea is what we do. So I hope that you won’t get hung up on whether or not you have IBS, because it’s pretty much a useless diagnosis anyway.

Second, we've learned that diarrhea has many, many different causes, and we help people find them—all of them.

There Are Many Possible Causes of Diarrhea 🔍

Sometimes it's Cyclospora. We’ve been testing for Cyclospora in every patient for over 20 years, so we don’t miss it.

But sometimes it's Giardia. Sometimes it's Cryptosporidium. Sometimes it's one of many other parasites. Sometimes it's a bacterial infection. Sometimes it's an inflammatory condition and we need to find the cause. Sometimes it's food reactions. Sometimes it's something completely different.

The problem is that almost no one is ever thoroughly evaluated for ALL of the causes, even by a gastroenterologist. And even when you’ve had lots of tests done, they rarely are as thorough as you think they are.

A lot of doctors don't even order stool testing. Others order a limited panel that looks for only a handful of things.

Our Approach to Testing 🧪

We take a very different approach.

If parasites are a possibility, we don't just look for Cyclospora. We test for Cyclospora, along with a very broad range of other parasites, bacteria, and other potential causes of chronic diarrhea. In fact, we test for everything that can possibly be tested for.

Because honestly, if you're going to test, why stop after looking for just one organism?

What If Your Cyclospora Test Is Negative? 🤔

And here's something that's just as important.

Let's say your Cyclospora test comes back negative. Does that mean you're fine? Of course not. It simply means Cyclospora wasn't the answer.

The real question is: What IS causing your diarrhea?

That's the question we've been helping patients answer for decades.

We Don't Stop Looking Until We Find Answers 🌿

Many of our patients have already seen multiple doctors. Many have already been told they have IBS. Many have had normal colonoscopies. Many have been told to "just live with it."

We don't accept that. We keep looking until we find answers.

Our goal is always the same: Figure out why you're sick. We won’t stop until we do. And then we help you get well.

Don't Stop at One Test 💙

If you've developed diarrhea during this Cyclospora outbreak, you absolutely should be evaluated. And if it turns out not to be Cyclospora, don't stop there.

There are many, many other causes. And I guarantee you that there is ALWAYS a cause. You just need someone to help you find it.

If you've been suffering with diarrhea—whether it started recently or ten years ago—we'd be happy to help. We've been treating patients via telemedicine since 2005, so we can work with people almost anywhere. We even back our treatment program with a money back guarantee.

So if you have diarrhea, give us a call at 206-264-1111, and we’ll not only test you for everything, including Cyclospora, but we’ll help you get your life back.

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