What you should know about fatigue and Lyme disease

By Dr. Sharon Stills, NMD

There’s a lot of concerning news out there about tick-borne diseases like Lyme disease that cause fatigue, muscle pain, and fever. If they aren’t treated promptly, they can sometimes cause serious, chronic health issues. So if you are suffering from fatigue and you don’t know why, it’s worth considering whether the culprit could be Lyme disease.

What causes Lyme disease?

Black-legged ticks, also known as “deer ticks,” are the prime culprits of carrying Lyme disease, and the infection is most common in the northeastern and north central U.S.

The bacterium that causes Lyme disease, Borrelia burgdorferi, is so widespread in parts of the country that healthcare providers will now test for it — and the other, lesser-known tick-borne diseases, some of which have similar symptoms — in patients complaining of fatigue with no other obvious causes.

How do you know if you have Lyme disease?

The first thing many practitioners recommend — a blood test for Lyme disease — is controversial. That’s because blood tests for Lyme disease don’t actually look for the bacteria that causes Lyme disease, Borrelia burgdorferi. Instead, they look for antibodies to the bacteria. There are problems with this:

  • If you’re tested right away, you may not yet have developed enough antibodies for the test to detect.
  • Many people who had a Lyme infection in the past carry antibodies for years afterward. Yet they have no active infection.

You need to be cautious because there are a lot of false negatives happen through this standard testing. If you're told that you don't have Lyme disease but intuitively you feel that it's an issue for you and you're having symptoms that are unexplained -- maybe you're having neurological issues or memory issues, or you're having lots of unexplained joint pain and fatigue -- you really need to seek a naturopathic physician who works with a lab that provides more specific testing that looks at the cofactors and other ways of evaluating if Lyme actually is an issue for you. 

Diagnosis with a tick bite and Lyme disease symptoms

Some practitioners, knowing that testing isn’t accurate, will diagnose Lyme disease if you have a tick bite and symptoms consistent with Lyme disease. Unfortunately, there are problems with this approach as well:

  • The classic “bulls-eye rash” that most people associate with Lyme disease only occurs in 1 in 5 people. And 30% have no rash at all.
  • The initial infection may not produce serious (or any) symptoms early on. But a wide range of often debilitating symptoms may develop weeks, months or even years after the tick bite.
  • Even when systemic symptoms develop quickly, often they’re so vague and nonspecific that they may get blamed on something else. Especially if no rash appeared after the initial bite.
  • The ticks that carry Lyme disease also carry other bacteria that cause diseases with similar symptoms. Some people get multiple infections from the same tick bite.

As you can see, diagnosing Lyme can be very difficult. It definitely pays to be aware of all the questions and issues so you can get the best care possible.

How is Lyme disease treated?

If you’ve had a tick bite and have obvious symptoms, like a rash, you’ll likely be given antibiotics (usually amoxicillin) for up to 21 days. But there are important things to consider when it comes to antibiotic treatment:

  • A number of studies show that antibiotic therapy successfully treats localized (early) Lyme if initiated within 2 to 3 weeks after the initial infection. But for those with disseminated (late) Lyme disease, who don’t develop symptoms for weeks to months later — including the 30% who don’t have a rash — antibiotics often don’t workas well.
  • Three weeks of antibiotics has a very serious impact on the body, particularly the gut flora. And there’s no guarantee it will cure the infection. Studies have shown that anywhere from 16% to 48% — almost half! — of patients experience continued or recurrent Lyme symptoms after finishing their treatment.
  • There’s also the problem of coinfections. For example, black-legged ticks also carry other infectious bacteria, some of which don’t respond as well to amoxicillin. So even if the Lyme is cured, the patient might still have symptoms related to anaplasmosis or babesiosis nonetheless. And think she still has Lyme!

And then there’s chronic Lyme disease…

Chronic Lyme: the disease that “doesn’t exist”

Until recently, the Centers for Disease Control and Prevention (CDC) flatly dismissed the idea of “chronic Lyme disease.” Despite many patients reporting debilitating long-term symptoms after being treated for Lyme disease.

Fortunately, recent studies have verified the existence of post-treatment Lyme disease syndrome. In fact, the CDC now includes information about it on their website.

But many practitioners haven’t gotten the word that there really is a chronic condition related to Lyme infection. Patients with ongoing symptoms of fatigue, joint pain or fuzzy thinking may find themselves facing a skeptical healthcare provider who doesn’t recognize the symptoms’ relationship to Lyme disease.

We still don’t know a lot about Lyme disease or why post-treatment Lyme syndrome occurs. And there is no consensus at all about how to treat it. Retreatment with IV antibiotics isn’t particularly effective and may be harmful.

This leaves many people with chronic symptoms related to Lyme disease in a difficult place. There’s no question that they’re suffering from debilitating symptoms. And they deserve a practitioner who takes their concerns seriously. So do you! If your doctor isn’t open to your questions, I encourage you to find someone who is.
