A health disorder that results from the deficiency of thyroxine in adults and is characterised by (i) a low metabolic rate, (ii) increase in body weight and (iii) tendency to retain water in tissues is
A Cretinism
B Hypothyroidism
C Simple goitre
D Myxoedema

Detailed Solution

Deficiency of thyroid hormones is called hypothyroidism in general; its specific forms have separate names.
In adults, deficiency of thyroxine causes myxoedema: low basal metabolic rate, gain in body weight, puffy appearance due to retention of water (accumulation of mucopolysaccharides under the skin), lethargy and low body temperature.
Cretinism is the result of thyroid hormone deficiency in infants and children: stunted growth, mental retardation, low intelligence quotient and abnormal skin.
Simple goitre is the enlargement of the thyroid gland due to deficiency of iodine in the diet.
Since the question specifies adults and these three symptoms, the disorder is myxoedema.
