Dr_ Vouyiouklis: Sluggishness can be seen in patients with hypothyroidism (underactive thyroid). If the TSH is in the normal range of 0.4-4.5 (depending on the laboratory), it is less likely that your symptoms are a result of this.TSH is a very sensitive marker for thyroid function, so while a free T4 may be additional useful information, a TSH should be able to indicate if there is thyroid dysfunction.our TSH at 5.1 remains slightly elevated, so you should probably have your dose adjusted. Please note that the TSH range is wide. Also, it can take up to six weeks to three months to see changes in thyroid function, and it can sometimes take time to see a complete response to the medication.
