I hope you\u2019ve been intrigued by the Health Tips on Functional Medicine<\/a> we\u2019ve written in the past month. It\u2019s especially provocative that a growing number of physicians, as well as the Cleveland Clinic, are using functional medicine tests when challenged by a patient with longstanding, unexplained chronic symptoms whose conventional test results have been negative.<\/p>\n\n\n\n

What exactly is a Functional Medicine test and how does it differ from the ones you\u2019ve been getting all along from your family doctor?<\/p>\n\n\n\n

Just as the word itself conveys, a functional test of one of your body\u2019s systems (digestive, cardiac, hormonal, etc.) checks how efficiently that system is working. The single most common conventional test in gastroenterology checks your stools for the presence of blood. The result gives you exactly one piece of information: either you have some internal bleeding or you do not. It tells you absolutely nothing about how your GI system is functioning.<\/p>\n\n\n\n

Here\u2019s a simple comparison I hope will provide an \u201caha!\u201d moment leading to all of functional medicine becoming clear to you.<\/p>\n\n\n\n

Conventional medicine for GI symptoms
<\/strong>Let\u2019s say you have chronic indigestion: bloating, gas, diarrhea, and\/or constipation. Instead of feeling good and satisfied after eating, you feel crummy. You try eliminating certain foods and you\u2019re not sure it makes a difference.<\/p>\n\n\n\n

You go to your doctor, who prescribes Pepcid or Nexium (they\u2019re all the same), but nothing changes.<\/p>\n\n\n\n

She sends you to a gastroenterologist, who listens to your symptoms, says \u201cseems like irritable bowel syndrome,\u201d and instructs you to reduce stress and eat more fiber. You follow the guidelines and still nothing changes.<\/p>\n\n\n\n

A month later you\u2019re back again, and this time you get scheduled for a gastroscopy and colonoscopy. Both are singularly unpleasant experiences, and afterward your test results are completely normal. The gastroenterologist shrugs and stands by his diagnosis of IBS.<\/p>\n\n\n\n

A friend recommends you see a functional medicine doctor. (If she\u2019s a really good friend, she\u2019ll insist you go to WholeHealth Chicago.)<\/p>\n\n\n\n

Functional medicine for GI symptoms
<\/strong>After we listen carefully to you describe your symptoms and perform a physical examination, you\u2019ll have some blood drawn and will leave the office with three functional medicine kits, instructions for specimen collection, and some FedEx envelopes for sending your specimens directly to the lab.<\/p>\n\n\n\n

Likely you\u2019ll receive:<\/p>\n\n\n\n

Comprehensive Digestive Stool Analysis with screen for parasites and yeast (Candida)<\/u><\/a>
This is the granddaddy of functional tests, used by thousands of practitioners (MDs, chiropractic physicians, naturopaths, osteopathic physicians, and clinical nutritionists) for more than 30 years. It\u2019s not simply one test. Once you\u2019ve sent in the vials containing your stool sample (you\u2019re given a collection set to make it almost easy), the lab will perform up to 25 individual tests that will reveal how you\u2019re digesting and absorbing your food, whether or not you have a healthy balance of bacteria, and if you have an infection with a parasite or candida.<\/p>\n\n\n\n

If each test were run separately at a medical center like Northwestern, your bill would be well over $5,000 (I once calculated this), but using functional labs (like Genova, Doctor\u2019s Data, and Great Plains) the price of this series is less than $500, with health insurance frequently offsetting some of the expense.<\/p>\n\n\n\n

Test for hidden food sensitivities<\/u> \u00a0<\/strong>This is a blood test that determines if your immune system is treating any of 96 commonly eaten foods as the enemy and creating antibodies in defense.\u00a0<\/a> Unlike food allergies, which are immediate (lip swelling after eating strawberries, for example), sensitivity symptoms can occur one to three days after eating an offending food, usually manifesting as chronic indigestion. I urge you click the link above and spend a few minutes with the easy-to-understand report. At left the bars show foods to which the sample patient has no reaction. Bars extending to the right indicate foods that are causing an extremely high reaction. Look at the sample patient\u2019s response to chicken and duck eggs, which is extremely high. Wheat, dairy, and tomatoes are also triggers.<\/p>\n\n\n\n

Sometimes an irritating food will have already damaged your intestinal lining<\/u>, producing a condition called leaky gut (also known as intestinal hyperpermeability). The presence of a leak can be revealed via a urine test (Genova)<\/a> or a bloo<\/a>d test (Cyrex Labs)<\/a>. As you might guess, eliminating irritating foods and healing leaky gut is a far better approach than \u201cirritable bowel–reduce stress, eat fiber.\u201d<\/p>\n\n\n\n

If bloating is a major issue<\/u>, testing for small intestinal bacterial overgrowth (SIBO) is a quick and easy take-home functional test<\/a>. You begin by stimulating bacterial growth via drinking a pleasant-tasting liquid. Then every 30 minutes for three hours you blow into a balloon, snap on a vacuum tube, and send what looks like a box of empty tubes to the lab for gas analysis. Too much methane or hydrogen (or both) is likely responsible for your bloat. SIBO is surprisingly easy to treat with either antibiotics or more natural remedies.<\/p>\n\n\n\n

I hope you\u2019re now appreciating the difference between a single digestive test (like a stool culture or a colonoscopy) and a functional analysis of your entire gastrointestinal system.<\/p>\n\n\n\n

Over the years I\u2019ve taken care of numerous patients with chronic symptoms who underwent multiple (and completely normal) colonoscopies when all they needed was to take some digestive enzymes (as they learned from their Comprehensive Digestive Stool Analysis) or to eliminate dairy (as revealed by their food sensitivity profile).<\/p>\n\n\n\n

Future of functional testing
<\/strong>Functional testing has now expanded to check your hormones; the state of your nutrition (vitamins, minerals, amino acids, fatty acids, neurotransmitters); your risks for cancer, osteoporosis, and heart disease; how efficiently you eliminate toxins; and how you handle oxidative stress.<\/p>\n\n\n\n

One of the most exciting areas of functional medicine uses a quick scraping of the inside of your cheek (like 23andMe) to look at your genetic susceptibility to long-term health risks, what type of diet is best for you, what supplements are useful (and which you don\u2019t need), and even what physical activities will be most helpful to your body.<\/p>\n\n\n\n

In order to keep up with our patients\u2019 demand for functional medicine physicians, later this month WholeHealth Chicago will welcome to its staff Neeti Sharma, MD, a board-certified internist like me, but who also has postgrad training at the Institute of Functional Medicine. We\u2019re all looking forward to working with her.<\/p>\n\n\n\n

More later and\u2026<\/p>\n\n\n\n

Be well,
David Edelberg, MD<\/em><\/p>\n\n\n\n
