Subclinical Hypothyroidism

In screening patients for thyroid disease, physicians often free thyroxine (T4) levels are increased in patients with non-subnormal TSH-stimulating hormone (TSH) levels, you can find. This state, called "subclinical hypothyroidism," an early stage of hypothyroidism, the most common. Resolve the situation remains unchanged, or in a few years in some patients, though, hypothyroidism significantly elevated TSH levels and low free T4 levels, as well as develops. This is a big possibility of TSH will be increased with the rise and detectable antithyroid antibodies. Sometimes subtle symptoms of hypothyroidism in patients with subclinical hypothyroidism and serum lipoprotein and mild abnormalities in cardiac function may be because the final and permanent thyroid therapy should be considered for patients with elevated serum TSH levels. Levothyroxine, a dose that protects TSH level within the normal range, the preferred method of treatment in these patients.
Hypothyroidism is very common in older people. In one study, mL (10 mU per L) per 1 to 10 μU thyrotropin-stimulating hormone (TSH) levels 7 percent of women living more active lives, and found the age group 60 to 89 years of age, 3 per cent of men (normal range: approximately 0.5 to 4.5 μU per mL [0.5 to 4.5 mU per L]).Such as fatigue and constipation, and other early signs, symptoms such as thyroid deficiency may be due to aging itself, because elderly patients with clinical suspicion of hypothyroidism may be delayed. The difficulty of making an early clinical diagnosis of thyroid failure and high prevalence of hypothyroidism in older people, especially a simple test, since the serum TSH level, is included in this group may be useful for the scan.
Advice on the thyroid scan, but has been inconsistent. Today, the organizations recommend routine universal screening. Is insufficient evidence of clinical benefit, for example, the U.S. Preventive Services Task kuvveti2 advised not screened asymptomatic adults. More recently, some authors3 women over 40 years of age and have recommended to test patients in geriatric facilities. Danese and co-workers4 prevented the progression of overt hypothyroidism because the TSH 35 years, starting with a screening every five years, cost-effective model with a decision that showed decreased serum cholesterol levels and the symptoms improved with early treatment of hypothyroidism.
In the absence of strict rules, some clinicians to perform routine screening with serum TSH measurement or continuous non-specific complaints, especially the women, the elderly and persons with risk factors for thyroid failure in patients with TSH measurement may prefer
