Now match the condition below with the description of the disorder.

Diabetes insipidus

Thyrotoxicosis

Myxoedema

Addison’s Disease

1. Disorder of carbohydrate metabolism in which sugars in the body are not oxidised to produce energy due to lack of the pancreatic hormone insulin

2. The production of large quantities of very dilute urine due to the failure of the pituitary gland to secrete ADH

3. Syndrome due to excessive amounts of thyroid hormones in the blood-steam, causing a rapid heartbeat, sweating, tremor, anxiety, increased appetite, loss of weight, and intolerance of heat

4. The clinical syndrome due to hypothyroidism in adult life, including coarsening of skin, intolerance to cold, weight gain, and mental dullness

5. A syndrome of dwarfism, mental retardation, and coarseness of the skin and facial features due to lack of thyroid hormone from birth

6. Abnormal growth causing excessive height, most commonly due to over-secretion during childhood of growth hormone by the pituitary gland

7. A deficiency of growth hormone due to a defect in the pituitary gland; they are well proportioned and show no mental retardation, but may be sexually underdeveloped

8. A syndrome, due to insufficient secretion of corticosteroid hormones by the adrenal glands. Symptoms include weakness, loss of energy, low blood pressure, and dark pigmentation of the skin

9. The condition resulting from excess amounts of corticosteroid hormones in the body. Symptoms include weight gain, reddening of the face and neck, excess growth of body and facial hair, raised blood pressure, loss of mineral from the bones, raised blood glucose levels, and sometimes, mental disturbances
