Exophthalmos:
Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))
The obvious effect is a bulging eyeball, commonly with diplopia, if extraocular muscle edema causes misalignment. (See Recognizing exophthalmos.) A rim of the sclera may be visible below the upper lid as lid retraction occurs, and the patient may blink infrequently. Other symptoms depend on the cause: pain may accompany traumatic exophthalmos; a tumor may produce conjunctival hyperemia or chemosis; retraction of the upper lid predisposes to exposure keratitis. If exophthalmos is associated with cavernous sinus thrombosis, the patient may exhibit paresis of the muscles supplied by cranial nerves III, IV, and VI; limited ocular movement; and a septic-type (high) fever.

Hyperthyroidism:
Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))
The classic features of hyperthyroidism are an enlarged thyroid (goiter), nervousness, heat intolerance, weight loss despite increased appetite, sweating, diarrhea, tremor, and palpitations. Exophthalmos is considered most characteristic but is absent in many patients with hyperthyroidism. Many other symptoms are common because hyperthyroidism profoundly affects virtually every body system:
❑ Central nervous system: difficulty in concentrating because increased T4 secretion accelerates cerebral function; excitability or nervousness due to increased basal metabolic rate; fine tremor, shaky handwriting, and clumsiness from increased activity in the spinal cord area that controls muscle tone; emotional instability and mood swings, ranging from occasional outbursts to overt psychosis
❑ Skin, hair, and nails: smooth, warm, flushed skin (patient sleeps with minimal covers and little clothing); fine, soft hair; premature graying and increased hair loss in both sexes; friable nails and onycholysis (distal nail separated from the bed); pretibial myxedema (dermopathy), producing thickened skin, accentuated hair follicles, raised red patches of skin that are itchy and sometimes painful, with occasional nodule formation (Microscopic examination shows increased mucin deposits.)
❑ Cardiovascular system: tachycardia; full, bounding pulse; wide pulse pressure; cardiomegaly; increased cardiac output and blood volume; visible point of maximal impulse; paroxysmal supraventricular tachycardia and atrial fibrillation (especially in the elderly); and occasionally, systolic murmur at the left sternal border
❑ Respiratory system: dyspnea on exertion and at rest, possibly from cardiac decompensation and increased cellular oxygen utilization
❑ GI system: possible anorexia; nausea and vomiting due to increased GI mobility and peristalsis; increased defecation; soft stools or, with severe disease, diarrhea; and liver enlargement
❑ Musculoskeletal system: weakness, fatigue, and muscle atrophy; rare coexistence with myasthenia gravis; generalized or localized paralysis associated with hypokalemia may occur; and occasional acropachy — soft-tissue swelling, accompanied by underlying bone changes where new bone formation occurs
❑ Reproductive system: in females, oligomenorrhea or amenorrhea, decreased fertility, higher incidence of spontaneous abortions; in males, gynecomastia due to increased estrogen levels; in both sexes, diminished libido
❑ Eyes: exophthalmos (from the combined effects of accumulation of mucopolysaccharides and fluids in the retro-orbital tissues that force the eyeball outward, and of lid retraction that produces the characteristic staring gaze); occasional inflammation of conjunctivae, corneas, or eye muscles; diplopia; and increased tearing.
Alert When hyperthyroidism escalates to thyroid storm, these symptoms can be accompanied by extreme irritability, hypertension, tachycardia, vomiting, temperature up to 106° F (41.1° C), delirium, and coma.

Simple goiter:
Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))
Thyroid enlargement may range from a mildly enlarged gland to a massive, multinodular goiter. (See Massive goiter, page 840.) Because simple goiter doesn’t alter the patient’s metabolic state, clinical features arise solely from enlargement of the thyroid gland. The patient may complain of respiratory distress and dysphagia from compression of the trachea and esophagus, and swelling and distention of the neck. In addition, large goiters may obstruct venous return, produce venous engorgement and, in rare cases, induce development of collateral venous circulation in the chest. Obstruction may cause dizziness or syncope (Pemberton’s sign) when the patient raises her arms above her head.

Thyrotoxicosis:
Signs and symptoms
(Handbook of Diseases)
The classic features of Graves’ disease are an enlarged thyroid (goiter), nervousness, heat intolerance, weight loss despite increased appetite, sweating, frequent bowel movements, tremor, and palpitations. Exophthalmos is considered most characteristic but is absent in many patients with thyrotoxicosis.
Many other signs and symptoms are common because thyrotoxicosis profoundly affects virtually every body system:
❑ Central nervous system: difficulty in concentrating because increased thyroxine secretion accelerates cerebral function; excitability or nervousness due to increased basal metabolic rate; fine tremor, shaky handwriting, and clumsiness from increased activity in the spinal cord area that controls muscle tone; emotional instability and mood swings, ranging from occasional outbursts to overt psychosis
❑ Skin, hair, and nails: smooth, warm, flushed skin (patient sleeps with minimal covers and little clothing); fine, soft hair; premature graying and increased hair loss in both sexes; friable nails and onycholysis (distal nail separated from the bed); pretibial myxedema (dermopathy), producing thickened skin; and accentuated hair follicles, raised red patches of skin that are itchy and sometimes painful, with occasional nodule formation. Microscopic examination shows increased mucin deposits.
❑ Cardiovascular system: tachycardia; full, bounding pulse; wide pulse pressure; cardiomegaly; increased cardiac output and blood volume; visible point of maximal impulse; paroxysmal supraventricular tachycardia and atrial fibrillation (especially in elderly people); and, occasionally, a systolic murmur at the left sternal border
❑ Respiratory system: dyspnea on exertion and at rest, possibly from cardiac decompensation and increased cellular oxygen utilization
❑ GI system: excessive oral intake with weight loss; nausea and vomiting due to increased GI motility and peristalsis; increased defecation; soft stools or, with severe disease, diarrhea; and liver enlargement
❑ Musculoskeletal system: weakness (especially in proximal muscles), fatigue, and muscle atrophy; rare coexistence with myasthenia gravis; possibly generalized or localized paralysis associated with hypokalemia; and occasional acropachy (soft-tissue swelling, accompanied by underlying bone changes where new bone formation occurs)
❑ Reproductive system: in females, oligomenorrhea or amenorrhea, decreased fertility, higher incidence of spontaneous abortions; in males, gynecomastia due to increased estrogen levels; in both sexes, diminished libido
❑ Eyes: exophthalmos (produced by the combined effects of accumulation of mucopolysaccharides and fluids in the retroorbital tissues that force the eyeball outward, and of lid retraction that produces the characteristic staring gaze); occasional inflammation of conjunctivae, corneas, or eye muscles; diplopia; and increased tearing.
When thyrotoxicosis escalates to thyroid storm, these symptoms can be accompanied by extreme irritability, hypertension, tachycardia, vomiting, temperature up to 106° F (41.1° C), delirium, and coma.
Clinical tip Consider apathetic thyrotoxicosis in elderly patients who exhibit atrial fibrillation or depression.

Article Excerpts About Symptoms of Hyperthyroidism:
Hashimoto's Thyroiditis: NWHIC (Excerpt)
This is a condition that occurs from overproduction of thyroid hormones.
These symptoms include insomnia, irritability, weight loss without
dieting, heat sensitivity, increased perspiration, thinning of your skin,
fine or brittle hair, muscular weakness, eye changes, lighter menstrual
flow, rapid heart beat and hand tremors. (Source: excerpt from Hashimoto's Thyroiditis: NWHIC)
Thyroid Disease: NWHIC (Excerpt)
Symptoms may
include nervousness, irritability, shaky hands, increased perspiration,
warm skin, thinning hair, weight loss, decreased menstruation, eye
changes, and weak leg muscles. Grave's disease is the most common form of
hyperthyroidism. It is an autoimmune condition in which the body produces
antibodies that overstimulate the thyroid gland, so that it produces too
much thyroid hormone. (Source: excerpt from Thyroid Disease: NWHIC)
