The Little-Known IBS Treatment which Actually Works - Hollywood Homestead
Two of the most common treatments for IBS are fiber supplements for constipation and antispasmodics for diarrhea.  As I talk about in this post about common IBS treatments,  neither of these treatments solve the underlying cause of IBS.  In a fact, they could make your IBS worse in the long run.

Both diarrhea and constipation result because of problems with motility.   Motility refers to the wave-like contractions of the muscles in the GI tract which move food and waste throughout it. There are two types of motility. The first is peristalsis and it moves food that you have eaten.


The second type of motility doesn’t get talked about as much, but it is very important for maintaining a healthy balance of gut bacteria. It is called the Migrating Motor Complex (MMC). You can help control your MMC — and thus treat your IBS — by using prokinetics.


The Migrating Motor Complex

Unlike peristalsis which is triggered when you eat, taste or thinking about food in order to start the digestion system, the MMC occurs after you haven’t eaten food in a while. Researchers believe that the MMC acts like a “housekeeping” function to keep our intestines clean.

Though medical researchers have known about the MMC for a long time now, there is a lot we don’t know about it and many doctors don’t even realize how important it is for gut health and preventing/treating GI diseases like IBS.

There are actually two different MMC. The first MMC starts in your stomach and travels through the small intestine. The second MMC starts duodenum and travels up to the ileocecal valve in the large intestine.

The wave-like movements push undigested food and waste out of our small intestines.   There are two main ways that the MMC helps us keep our gut bacteria balanced. The first is by removing waste from the intestines. When your small intestine is clear, then bacteria won’t be able to feed off of it and grow out of control.   The second way MMC helps is because its sweeping wave-like motions clean out excess bacteria.

During MMC, there are also increases in gastric, biliary, and pancreatic secretions.  These secretions probably also help clean out the small intestine of bacteria buildup.

Studies have shown that people with IBS have disrupted MMC. It is unclear how this happened. It could be that a bacterial infection disrupted the balance of the gut flora and then the gut flora wasn’t able to signal the MMC properly. Or maybe it was bad diet which damaged the nerves in the gut so MMC couldn’t function properly. Regardless of the cause, if your MMC isn’t working properly, you are going to end up with a buildup of bacteria in your gut. This bacteria buildup (SIBO) might be the real cause of your IBS.

To cure SIBO (if you are one of the 84% of IBS patients who test positive for it) or reset your gut bacteria (if your gut bacteria is unbalanced but not necessarily overgrown as is the case with SIBO), then you must stimulate the MMC to make sure waste is getting flushed out of the intestines. If you have diarrhea, the idea of stimulating your MMC might seem scary – you don’t want more movement happening!  But it is important to realize that the MMC doesn’t go past the large intestine.  It will not worsen your diarrhea.

UPDATE: Want to know if SIBO is the real cause of your IBS? The good news is that there is now a SIBO breath test (the gold standard lactulose one) that you can order directly without a doctor’s order! While I’m a HUGE fan of having a doctor’s guidance, I understand the need to know whether you have SIBO or not before you invest in a practitioner. You can order the test directly here and it will be sent to your home (in every state except New York). Hope that helps!

Cycles of the MMC

Peristalsis occurs when you eat food.  By contrast, the MMC only starts when you haven’t eaten food for a while.  Again, this has to do with the apparent role of the MMC as a housekeeper to get out all that undigested food which is why prokinetics before bed are a good idea.

Cycles of the MMC can vary a lot depending on the person.  However, research generally shows that the MMC starts about 1 ½ to 2 hours after not eating.  If you are the type of person who “grazes” on food throughout the day, you could be preventing your MMC from starting!  Registered Dietician Tamara Duker Freuman says that you should lay off snacking if you’ve got GI problems related to motility.

Once it begins, the MMC is divided into 4 phases:

  • A calm period lasting about 45 to 60 minutes
  • A period of peristaltic contractions which increase in frequency and last for about 30 minutes
  • A period of rapid, evenly-spaced peristaltic contractions lasting about 5 to 15 minutes
  • A short transition period until phase 1 starts again

One interesting thing to note is that there appears to be a link between MMC cycles and sleep cycles.   They appear in similar frequency, have cyclic patterns, and are disrupted by sensory stimuli (such as food with the MMC).  There are theories that they are linked, which makes one wonder if lack of sleep could be related to IBS in this way.


Wait At Least 4-5 Hours Between Meals

Do the math: It takes about 1 ½ to 2 hours for the MMC to begin.  Then it takes about 1 hour 45 minutes for the MMC to go through all its phases.  If you eat during this time, then the MMC will stop.  To make sure the MMC is able to do its housekeeping job, you’ve really got to wait at least 3 hours 45 minutes between meals, without grazing or snacking.

Dr. Pimental, who is a leading expert on IBS, originally said in his book A New IBS Solution that you should wait 3-5 hours between meals.  Then he changed his recommendation to 4-5 hours.  Everyone’s MMC seems to be a bit different.  To play it safe, I’d wait for at least 5 hours between meals.   That means no snacks, coffee, tea, or anything except water.


Can’t I Just Take a Laxative for IBS?

The problem with laxatives is that they do not trigger the MMC.  Some types of laxatives act as stimulants which do trigger peristalsis, so food is moved throughout the GI tract faster – but it won’t help clean out any leftover undigested particles which linger about, nor any excess bacteria.  Laxatives also don’t trigger gastric, biliary, or pancreatic secretions like the MMC does to clean out bacteria.

Other types of laxatives are not stimulants, but rather “stool softeners.”  They work by drawing water from the intestines and into stool, so your constipation essentially turns to diarrhea.  Aside from dehydrating you, these laxatives are made from fiber which could be fermentable – which is a major no-no for IBS and SIBO!

Of course, if constipation is a big issue for you, the occasional use of glycerine suppositories is absolutely fine but just know this won’t do a thing for your MMC.


Using Prokinetics to Stimulate the MMC

I used prokinetics along with the elemental diet to reset my gut bacteria, but note that my IBS was really SIBO. What worked for me might not work for you, or even for someone else who had IBS misdiagnosed as SIBO. Check with your doctor to see which prokinetic is right for you.

The prokinetics I used in my treatment were Motilpro, Iberogast, and Erithromycin.

Three prokinetics which have shown promise in treating IBS are Tegaserod, Cisapride, and Renzapride. Unfortunately, there have only been limited studies on these and even then in just constipation-dominant and mixed IBS.
