The pituitary stalk interruption syndrome (PSIS) treatment market will be able to see huge growth from 2025 to 2035 owing to the increased congenital hormone deficiency cases and progress in endocrinology treatments. The market is anticipated to be approximately USD 121.1 million in 2025 and is expected to grow as high as USD 168.2 million by 2035 at a compound annual growth rate (CAGR) of 3.3% throughout the forecasting period.
There are several reasons why market dynamics have altered. There is a growing diagnosis of PSIS among children and adolescents, which is one of the strongest reasons and, in turn, increases the requirement for hormone replacement therapy.
Growth hormone therapy is the central dependence of PSIS patients to manage retardation of growth and other endocrine diseases. Low awareness and late diagnosis issues still prevail. These challenges compel the medical experts to develop more efficient diagnostic methods and specialized treatment forms, offering early treatment and better patient outcomes.
