Benign thyroid nodules can trigger atrial fibrillation or osteoporosis in older people. That's why experts recommend having a laboratory test or an ultrasound scan from the age of 65.
In around five percent of people over 65, thyroid nodules trigger a mild overactive thyroid, a so-called latent hyperthyroidism. Even if a slight hyperfunction often does not cause any noticeable symptoms, it can have serious effects on the cardiovascular system and bone metabolism, says Dr. Detlef Moka, Chairman of the Professional Association of German Nuclear Medicine Doctors (BDN). The risk of vertebral body fractures is more than twice as high as for neck fractures in people aged 65 and older. If nodules larger than one centimeter are present, scintigraphy is recommended to identify the nodules and treat the problem. If you have a mild hyperfunction, you should see your doctor as soon as you turn 65.
