The prognosis for idiopathic conditions can vary greatly. Some conditions like idiopathic constipation are often manageable with lifestyle changes and may improve over time. Others, like idiopathic juvenile arthritis, may require long-term management but can often be controlled with appropriate treatments. Idiopathic scoliosis may need ongoing monitoring and, in some cases, surgical intervention. Each child's prognosis will depend on the specific condition, its severity, and how well it responds to treatment.
