Hypothyroidism is a condition in which the thyroid gland does not produce a sufficient amount of the thyroid hormones thyroxine (T4) and triiodothyronine (T3). Thyroid hormone regulates metabolism—the way the body uses energy—and affects nearly every organ in the body. Without enough thyroid hormone, many of the body’s functions slow down. Mood disturbances ,easy fatigability ,tiredness , lethargyness ,weight gain , slowness of memory ,intellect and thoughts, dry and coarse skin ,menstrual irregularities ,constipation and generalized swelling are major clinical features of hypothyroidism. According to the principles of Ayurveda, we find that it is basically caused due to dysfunctioning of the Agni. Hypofunctioning of Jatharagni, which in turn, affects Dhatvagni, eventually, brings out pathological sequence & ultimately, the diseased condition is developed. Looking into its Doshika dominance, Kapha associated Pitta Dushti with vitiation of Vayu due to Margavarana and predominantly, Rasavaha , Annavaha and Medovaha Srotodushti can be considered as cause of the disease.
