Most of the time subclinical hypothyroidism is asymptomatic; however, some may exhibit mild symptoms typically of hypothyroidism. According to research, approximately 2–5% of individuals with subclinical hypothyroidism progress to overt hypothyroidism each year. From an Ayurvedic perspective, this condition can be correlated with Rasapradoshaja Vikara, where there is vitiation of Kapha dosha and impairment of Rasavaha srotas, often manifesting as Agnimandya(~Weak digestion), tandra(~Drowsiness), and gourava(~Heaviness). Based on this understanding, a treatment protocol addressing Rasapradoshaja Vikara—including Langhana (~Lightening theraphy), Deepana (~Appetizer)-Pachana (~Carminative), and selective Shodhana—was adopted. The results were found to be positive, with improvements in subjective symptoms as well as in the thyroid function test.
