Most problems arise because something either prevents the body from functioning properly or there is lack of cofactors needed for the particular biochemical processes. In the first case, an excess of simple carbohydrates and trans fats, intolerant foods, different toxins, overloading with heavy metals, viruses, parasites and other pathogens can become interfering agents. The second common cause is a deficiency of vitamins, micro- and macronutrients needed for the optimal performance of our body.

This can be caused by consumption of nutritionally depleted foods, monotonous diet, dietary restrictions or difficulties in absorbing nutrients. The challenge is to find the cause of the adverse symptom and eliminate it, thus giving the body an opportunity to restore its natural function. If the problem has been neglected for too long and non-medical methods alone are insufficient, appropriate functional medicine doctor shall be appointed.
