Does your belly determine what you can do today?

We are Jeroen and Roelie,
With specialized research we will provide insight into the source of the IBD and the complaints you experience. With that information you’ll learn how to restore your health!

Does Crohn’s disease or Ulcerative Colitis determine your life?

Do you regularly feel pain and discomfort in your stomach? Do you react violently to certain foods? Do you suffer from gas formation and a bloated stomach? Do you have irregular bowel movements, constipation or continuous diarrhea? Are you tired quickly and have little energy?

Many people with Crohn’s disease or Ulcerative Colitis (IBD) experience these types of complaints, just like you. These types of complaints have a lot of influence on your life. Be honest, this is not what you want!

Do you remember what your life was like before your complaints arrived? When you could do what you wanted without worry. When you were not “chronically ill”. We cannot turn back the time. We can, however, make the complaints of the past.

Jeroen le Duc is the founder of Crohnproof and has personal experience with Crohn’s disease. Together with his team, he guides people like you to a life without complaints. With us you will learn how to regain control of your life!
