           (b)       acute illness including cerebrovascular accident, gastrointestinal bleed, myocardial infarction and pulmonary embolism;
           (c)        acute iodine load including iodine-containing drugs;
           (d)       drugs including sedatives, opioids, antipsychotics, selective serotonin reuptake inhibitors, phenytoin, beta blockers, diuretics and chemotherapeutic agents;

                                     being obese means having a Body Mass Index (BMI) of 30 or greater.
Note: BMI is also defined in the Schedule 1 - Dictionary.

(a)          an average intake of more than 1,100 micrograms of iodine per day for adults, or more than 900 micrograms per day for those aged 18 years and under, for a continuous period of at least 3 months; or
(b)           having a urinary iodine concentration of greater than 300 micrograms per litre, or greater than 500 micrograms per litre for pregnant women.
                                     MRCA means the Military Rehabilitation and Compensation Act 2004.
                                     myxoedema coma means a constellation of severe and life-threatening symptoms of rapid onset in a patient with biochemical evidence of decreased thyroxine level.  Characteristic symptoms and signs are decreased mental status and hypothermia, and hypotension, bradycardia, hyponatremia, hypoglycaemia and hypoventilation are typically present.
Note 1: Myxoedema coma is also known as decompensated hypothyroidism.
         Note 2: Myxoedema coma may be the first presentation of undiagnosed Hashimoto thyroiditis, or may complicate existing Hashimoto thyroiditis.
                                     one pack-year means the amount of tobacco consumed in smoking 20 cigarettes per day for a period of 1 year, or an equivalent amount of tobacco products.
         Note 1: An equivalent amount of tobacco products is 7,300 grams of smoking tobacco by weight, either in cigarettes, pipe tobacco or cigars, or a combination of same. For pipe tobacco, cigars or combinations of multiple tobacco types, 1 gram of tobacco is considered to be equal to one cigarette.
         Note 2: Pack-years are calculated by dividing the number of cigarettes smoked per day by 20 and multiplying this number by the number of years the person has smoked. For example, smoking 10 cigarettes per day for 10 years is equal to 5 pack-years, and smoking 40 cigarettes per day for 10 years is equal to 20 pack-years.
                                     regular smoking habit as specified means having smoked at least 3 pack-years of tobacco products, within a continuous 3 year period.
