Relationship Between Rhinitis, Nasal Obstruction and Hypothyroidism: A Follow Up Study with Pre-post Treatment with Levothyroxine.

Abstract

Hypothyroidism is the most common form of thyroid disorder in India, while, Rhinitis and Nasal obstruction are frequent complaints treated on regular basis in ENT OPD. Studies show that there is relationship between Rhinitis and Nasal obstruction with hypothyroidism. To assess the improvement in symptoms associated with Rhinitis and nasal obstruction in patients with hypothyroidism after treating with levothyroxine. 50 patients presenting in ENT OPD with rhinitis and nasal obstruction and diagnosed with hypothyroidism were selected. Complete history was taken and clinical examination was performed, Nasal Obstruction Symptom Evaluation Score, (NOSE) and Peak nasal inspiratory flow rate (PNIF) were noted. Biochemically proven hypothyroid patients were treated with adequate dosage of Levothyroxine. The patients were followed up and the above-mentioned tests were repeated at regular intervals (1month and 3month), Changes in these readings were recorded and maintained. Significant difference was found in TSH level, NOSE questionnaire, and PNIF reading in patients with hypothyroidism after treatment with levothyroxine (P value < 0.001). This was most commonly noted to occur in young and middle-aged population of age 15years to 50years (88%). In our study - An attempt was made to correlate the symptomatology with hypothyroidism. Treatment with levothyroxine in patients with rhinitis, nasal obstruction and biochemically proven hypothyroidism was found to be effective in improvement of symptoms. It was found that there is significant association between hypothyroid status and rhinitis with nasal obstruction.
