What Is Thyroid Disease in Elderly?
Thyroid problems are common in seniors and often go undiagnosed. Understanding thyroid disease helps seniors recognize symptoms and seek appropriate treatment.
Understanding Thyroid Function
The thyroid gland produces hormones regulating metabolism, energy, and body temperature. Thyroid hormones affect virtually every organ system. Proper thyroid function is essential for health.
Thyroid problems become more common with age. About 20 percent of women and 10 percent of men over 60 have some thyroid abnormality. Many cases go undetected.
Hypothyroidism in Seniors
Hypothyroidism, or underactive thyroid, means the thyroid produces insufficient hormones. It is more common than hyperthyroidism, especially in older women.
Symptoms include fatigue, weight gain, cold intolerance, constipation, dry skin, and cognitive slowing. These symptoms are often attributed to normal aging, delaying diagnosis.
Depression and cognitive impairment can result from hypothyroidism. Memory problems and mood changes may be the most noticeable symptoms. Testing thyroid function in depressed seniors is important.
Treatment with thyroid hormone replacement is straightforward and effective. Symptoms typically improve with proper dosing. Regular monitoring ensures optimal levels.
Hyperthyroidism in Seniors
Hyperthyroidism, or overactive thyroid, means excess thyroid hormone production. It is less common than hypothyroidism but has significant effects.
Classic symptoms include weight loss, rapid heartbeat, tremor, anxiety, and heat intolerance. However, older adults often have atypical presentations.
Atrial fibrillation may be caused by hyperthyroidism. Heart rhythm problems in seniors should prompt thyroid evaluation. Treating the thyroid may resolve the arrhythmia.
Apathetic hyperthyroidism occurs in some older adults. Instead of appearing hyperactive, they seem withdrawn and fatigued. This atypical presentation delays diagnosis.
Treatment options include medication, radioactive iodine, or surgery depending on the cause and patient factors.
Thyroid Nodules
Thyroid nodules become increasingly common with age. Most are benign but some are cancerous. Evaluation determines which nodules need treatment.
Ultrasound and biopsy help characterize concerning nodules. Not all nodules require biopsy. Guidelines help determine which warrant investigation.
Screening for Thyroid Disease
Routine thyroid screening in all seniors is controversial. However, testing is appropriate when symptoms suggest thyroid problems or as part of evaluation for depression, cognitive changes, or unexplained symptoms.
TSH blood test is the primary screening tool. Abnormal TSH leads to additional testing to characterize the problem.
