Hyperthyroidism
๐T4 level (if elevated)
โ Elevated T4 indicates the thyroid is overactive, producing excessive thyroid hormones.
โ Increased T4 leads to a hypermetabolic state, increasing heart rate and energy expenditure.
โ Can result in weight loss despite increased appetite.
โ May cause heat intolerance and sweating due to increased metabolism.
โ Can contribute to nervousness, tremors, and anxiety.
๐Neck assessment (goiter/enlargement)
โ Goiter can result from thyroid hyperplasia due to excessive stimulation of TSH receptors.
โ Enlargement may indicate Gravesโ disease, a common cause of hyperthyroidism.
โ Can cause difficulty swallowing or pressure symptoms if the gland is significantly enlarged.
โ May be associated with exophthalmos in Gravesโ disease.
โ Often soft and diffuse rather than firm nodular (depending on etiology).
Hypothyroidism
๐level (if elevated)
โ Elevated TSH is a primary indicator of hypothyroidism, showing the pituitary is compensating for low thyroid hormone levels.
โ Reflects negative feedback response: low T4 โ pituitary releases more TSH.
โ Prolonged elevation can lead to thyroid enlargement (goiter) in some cases.
โ Can indicate early hypothyroidism before clinical symptoms fully develop.
โ Helps guide thyroid hormone replacement therapy.
๐T4 level (if low)
โ Low T4 confirms reduced thyroid hormone production, causing a decreased metabolic rate.
โ Leads to fatigue, lethargy, and decreased energy.
โ May cause weight gain despite reduced appetite.
โ Can result in cold intolerance and dry, coarse skin.
โ Often correlates with constipation and bradycardia.
๐Clientโs weight
โ Weight gain occurs due to slowed metabolism in hypothyroidism.
โ Can contribute to fluid retention and puffiness (myxedema).
โ Often gradual and associated with reduced energy expenditure.
โ May worsen cardiovascular strain if left untreated.
โ Weight monitoring is important for assessing treatment effectiveness.
๐Skin assessment
โ Dry, coarse, and pale skin is characteristic of hypothyroidism.
โ Decreased sweating and oil production contribute to dryness and scaling.
โ May be accompanied by hair thinning and brittle nails.
โ Edema in extremities or periorbital area can occur (myxedema).
โ Skin changes are gradual and can reflect chronic hormone deficiency.
๐Energy level
โ Fatigue and extreme sleepiness are hallmark signs of hypothyroidism.
โ Reduced T4 levels slow metabolic processes, leading to lethargy.
โ Can impair physical activity and daily functioning.
โ Often accompanied by mental slowing, depression, and poor concentration.
โ Improvement in energy is a key indicator of effective thyroid hormone replacement therapy.
๐Temperature tolerance
โ Cold intolerance is due to decreased basal metabolic rate.
โ Low heat production leads to sensitivity to cold environments.
โ Can contribute to chronic fatigue and reduced activity.
โ May cause peripheral vasoconstriction and pale extremities.
โ Monitoring temperature perception is part of assessing symptom control in hypothyroidism.
๐Neck assessment (goiter/enlargement)
โ Enlargement may occur due to compensatory TSH elevation.
โ Can lead to pressure symptoms like dysphagia or dyspnea.
โ Often firm or nodular if longstanding iodine deficiency.
โ Goiter in hypothyroidism may coexist with dry skin and hair changes.
โ Neck assessment helps track progression or improvement with therapy.
