You have IBS. You don’t know why this is happening to you; you want some answers and you want solutions that will actually make a difference in your quality of life. You have tried changing your diet, you take a probiotic but it has not made a much difference. Maybe you have been to your gastroenterologist, but you still don’t have any solutions.

What do you do now?

IBS is a “functional disorder” of the digestive tract. You don’t diagnose it with a colonoscopy or endoscopy…your digestive tract looks normal. You don’t diagnose it with a blood test…your tests will be normal. A functional bowel problem like IBS requires a “functional solution”…you need a functional medicine doctor. With their help, you can discover what is preventing your gut from functioning properly. There is not a single cause for IBS and your personal root cause will not be the same as someone else with IBS. Below are listed some of the most common causes of IBS.

Most Common Causes

  • Hormonal imbalances
  • Neurotransmitter imbalance (especially serotonin and dopamine)
  • Food sensitivities or food allergies
  • Overgrowth of bacteria or yeast in the gut
  • Parasitic infection
  • Nutrient deficiencies
  • Immune system imbalances

These are the most common causes contributing to your IBS and there is a very good chance you have more than one of the problems listed above. Only a functional medicine doctor will know how to identify these problems and understand how they are related to IBS. An IBS solution requires an understanding of it’s various causes.

How these cause IBS?

Remember that IBS is a “functional disorder.” The causative factors listed above are preventing your digestive tract from working properly. Consider the following:

  • Women tend to suffer with IBS more than men, so doesn’t it make sense that hormones play a role?
  • Many who suffer with IBS also have anxiety or depression, doesn’t it make sense that chemicals like serotonin and dopamine could be a cause?
  • Most of your immune system is located in and around the digestive tract, so doesn’t it make sense that food allergies or immune system problems could be a cause?
  • Your gut if full of bacteria and yeast, doesn’t it make sense that an imbalance in these could be a factor in your IBS?

Who is going to consider these when treating you for IBS? Nobody. Unless they understand the functional aspects of the digestive tract.

Your gut does not function in isolation; other systems of your body have a profound effect on how it works. These other causes need to be evaluated and treated if you want to get down to the root cause of your IBS. If you have a functional problem, you need functional answers. Where do you get functional healthcare answers? From a functional medicine doctor or an integrative medicine doctor. You must look for the causes behind IBS; the effect of these causes is obvious…the causes are not.

Functional problems require Functional Solutions.

I wish you health, happiness and a better quality of life!
