Overactive thyroid in young age
linked to stroke risk--study
Having overactive thyroids, a condition medically known as hyperthyroidism, at a younger age may raise early stroke risk, warns a novel research.
Until now, the condition has been shown to elevate the stroke risk only in elderly but this study is the first one to probe its potential role in causing strokes in younger people.
"Strokes of undetermined cause account for between one-third and one-fourth of all ischemic strokes in young people," said Herng-Ching Lin, Ph.D., senior author of the study and professor at the School of Health Care Administration, College of Medicine, Taipei Medical University in Taipei, Taiwan. "To the best of our knowledge, hyperthyroidism has never been considered as a potential risk factor for stroke in the 18 to 44 age group."
Then the team compared these patients with 25,408 young adults who did not have the condition and followed their medical condition for five years. The average age of all the participants was 32 years.
As many as 198 people, including 31 of the hyperthyroidism patients and 167 patients of the comparison group, had ischemic stroke--strokes caused by blocked arteries--during the five year study period.
Results of the study
The researchers recommended that the young adults with overactive thyroid should be very particular about their lifestyle habits and maintain a healthy weight, remain active, and avoid smoking to reduce their modifiable risk factors for heart attack and stroke.
They should also undergo regular thyroid checkups to avoid any serious consequences.
The study appears in Stroke: Journal of the American Heart Association.
Hyperthyroidism and symptoms
Sometimes the condition is asymptomatic, but once diagnosed, it can be easily treated.
However, without treatment, hyperthyroidism can lead to serious heart problems, bone problems, and a dangerous condition called thyroid storm, according to WebMD.
