The main function of the gastrointestinal tract is to digest and absorb nutrients from our food that the body can use to support the function of our organs. If something disrupts this normal process, then we may not be able to absorb all, or some, of the specific nutrients we need. This disruption can arise from problems in the stomach, small intestine, liver and biliary system, or the pancreas gland. After a thorough discussion, if we suspect you have this, we will organise the correct tests to diagnose this.
