Signs and symptoms of hypothyroidism
Correct Answer: Face is pale, puffy, expressionless. Skin cold and dry. Hair brittle, hair loss. HR and
temperature lowered. Lethargy, fatigue, intolerance to cold. Mentation impaired.
1. Hypothyroidism results from decreased thyroid hormone production, slowing metabolic rate. Classic
findings: bradycardia, hypothermia, weight gain, constipation, delayed relaxation of deep tendon reflexes.
2. Severe hypothyroidism: myxedema (non-pitting edema, periorbital swelling, macroglossia). Myxedema
coma is life-threatening (hypothermia, altered mental status, hypoventilation).
3. Diagnosis: elevated TSH, low free T4. Levothyroxine is first-line therapy.
Signs and symptoms of hyperthyroidism
Correct Answer: Rapid HR (possible arrhythmia/angina). Nervousness, insomnia, rapid thought
flow, rapid speech. Skeletal muscle weakness/atrophy. Increased metabolic rate (heat production,
temp elevation, heat intolerance, warm/moist skin). Weight loss if caloric intake fails to match
increased metabolic rate.
1. Hyperthyroidism results from excess thyroid hormone, accelerating metabolism. Graves disease is
most common cause (autoimmune TSH receptor antibodies).
2. Other findings: lid lag, proptosis (exophthalmos), onycholysis (Plummer nails), pretibial myxedema
(Graves dermopathy), atrial fibrillation (especially in elderly).
3. Thionamides (methimazole, PTU), beta-blockers (symptom control), radioactive iodine, or
thyroidectomy are treatment options.
, Levothyroxine (Synthroid) therapeutic goal
Correct Answer: Resolution of signs/symptoms of hypothyroidism and restoration of normal lab
values for serum TSH and free thyroxine (T4).
1. Goal TSH range: 0.5-4.5 mIU/L (some guidelines 0.5-2.5 mIU/L for younger patients). In older adults
or those with cardiac disease, goal TSH 4-6 mIU/L to avoid subclinical hyperthyroidism (AFib,
osteoporosis).
2. Monitor TSH 6-8 weeks after dose change, then annually once stable. Pregnant women need more
frequent monitoring (target TSH <2.5 mIU/L first trimester).
3. Levothyroxine dosing: 1.6 mcg/kg/day; reduce dose in elderly and those with cardiac history. Take on
empty stomach 30-60 minutes before breakfast, separated from calcium/iron supplements by 4 hours.
Methimazole high risk patients
Correct Answer: Should be avoided in the first trimester of pregnancy (associated with aplasia
cutis, choanal atresia, esophageal atresia).
1. Methimazole is preferred for hyperthyroidism outside of pregnancy due to less toxicity than PTU.
However, PTU is preferred in first trimester when antithyroid drug needed.
2. Methimazole toxicity: agranulocytosis (sore throat, fever – monitor CBC with differential),
hepatotoxicity, lupus-like syndrome.
3. Monitoring: CBC with differential if signs of infection (sore throat, fever). LFTs if signs of liver
dysfunction (jaundice, dark urine, RUQ pain).
Ideal HbA1c goal for diabetic, non-pregnant adults
Correct Answer: Less than 7% (ADA recommendation for non-pregnant adults).
1. A1c target should be individualized: <6.5% in those with short duration, no CVD, and no hypoglycemia
(but risk of hypoglycemia increases).
2. Less stringent goal (A1c <8%) for those with: history of severe hypoglycemia, limited life expectancy,
advanced microvascular or macrovascular complications.
3. A1c measurement interval: every 3 months until <7%, then every 6 months if stable.
HbA1c value considered diagnostic of diabetes
Correct Answer: A value of 6.5% or greater (confirmed with repeat testing, unless symptomatic).
1. Other diagnostic criteria: fasting plasma glucose ≥126 mg/dL, 2-h OGTT ≥200 mg/dL, random glucose
≥200 mg/dL with classic symptoms of hyperglycemia.
2. Prediabetes: A1c 5.7-6.4%, fasting glucose 100-125 mg/dL, or 2-h OGTT 140-199 mg/dL.
3. A1c may be inaccurate in conditions affecting red blood cell turnover (anemia, hemoglobinopathies,
CKD).
