The correct option is
C Cretinism and myxoedema
- Diabetes mellitus occurs when there is increased levels of sugar in blood and this condition is called hyperglycaemia. This disorder is caused due to deficiency or low secretion of insulin hormone.
- Cretinism is the retarded physical and mental development due to hyposecretion of thyroid hormones.
- Myxoedema, also known as Gull's disease, occurs in adults due to hyposecretion of thyroid hormones after the physical and mental development is complete. This results in low metabolic rate of the body.
- Diabetes insipidus is a disorder in which there is less secretion of ADH due to which there is less water reabsorption in kidneys.
Hence, hypothyroidism causes cretinism and myxoedema.
So, the correct answer is 'Cretinism and myxoedema'.
