Subclinical hypothyroidism in patients with non specific symptoms.
J Med Sci Jan ;18(4):191-3.

Objectives: This study was conducted to find the frequency of sub clinical hypothyroidism in patients who presented with nonspecific symptoms. Material and Methods: This was a cross sectional observational study conducted on patients presenting in the outpatient department with nonspecific symptoms between January 2009 and December 2009. After evaluating patients for other medical conditions a thyroid function test was performed. A standardized questionnaire was filled with all the clinical details and results were tabulated. Results: Of the two hundred patients who were screened for thyroid status, 24 patients had an elevated TSH with a normal T4. Of these 16 were female. The frequency was highest in the 55 to 65 years age group. The most common symptom was weakness and lethargy. Conclusion: Subclinical hypothyroidism is a relatively common condition which is usually undiagnosed unless specifically looked for.
