Subclinical hypothyroidism

Subclinical hypothyroidism is a condition where only the serum level of thyroid-stimulating hormone from the front of the pituitary gland is a little bit above normal. The thyroid hormones produced by the thyroid gland are still within the laboratory’s normal range. Subclinical hypothyroidism is an early, mild form of hypothyroidism, a condition in which the body doesn’t produce enough thyroid hormones. Thyroid hormones help support heart, brain, and metabolic functions. When thyroid hormones aren’t working properly, this affects the body. According to published research, In one study, The pituitary gland, located at the base of the brain, secretes multiple hormones, including a substance called thyroid-stimulating hormone (TSH). TSH triggers the thyroid, a butterfly-shaped gland at the front of the neck, to make the hormones T3 and T4. Subclinical hypothyroidism occurs when TSH levels are slightly elevated but T3 and T4 are normal. Subclinical • a family history of autoimmune thyroid disease, such as • injury to the thyroid (for example, having some abnormal thyroid tissue removed during head and neck surgery) • the use of radioactive iodine therapy, a treatment for • taking medications that contain lithium or iodine A variety of things, most of which are outside of your control, increase the chances of developing subclinical hypothyroidism. These include: • Gender. A study published in the journal • Age. TSH tends to rise as you age, making subclinical hypothyroidism mor...

Subclinical hypothyroidism involves high levels of thyroid-stimulating hormone and typical thyroxine levels in the blood. This may be due to an autoimmune disease, a medication, or thyroid surgery. People with this condition may not experience symptoms. While thyroid hormone levels in a person’s blood will be within the acceptable range, they Treatment for subclinical hypothyroidism may include the thyroid hormone replacement medication This article explores subclinical hypothyroidism, including the causes, symptoms, diagnosis, and treatments. Share on Pinterest mixetto/Getty Images Subclinical hypothyroidism is an early, mild form of A person’s pituitary gland produces TSH, which, in turn, stimulates the thyroid gland, a butterfly-shaped organ at the base of the neck. The TSH causes the thyroid to produce thyroid hormones called triiodothyronine (T3) and thyroxine (T4). Thyroid hormones regulate metabolic processes in the body, including heart rate, digestive function, and brain development. Subclinical hypothyroidism Healthcare experts call it subclinical hypothyroidism because the free thyroid hormone levels are still normal. Some people do not experience symptoms; however, others can have the same symptoms that overt hypothyroidism would cause. If the thyroid is not producing enough T4 to meet the body’s needs, TSH levels will spike to overwork the thyroid.

Subclinical hypothyroidism is a state of contradiction, with an elevated thyroid-stimulating hormone (TSH) level suggesting hypothyroidism but a normal free thyroxine level. Symptoms that suggest hypothyroidism may or may not be present. Treatment of subclinical hypothyroidism has long been controversial because of normal increases in TSH with age, variability between TSH measurements, and concerns for harm from treatment. Previous guidelines suggested that levothyroxine treatment may be appropriate with hypothyroid symptoms or a TSH level exceeding 10 mIU per L based on limited evidence. A recent large trial in older adults suggests that treatment shows no benefit in many areas and possible harm. The BMJ/MAGIC Group sought to determine whether treatment of subclinical hypothyroidism increases quality of life measures, improves symptoms, or induces harm. Studies of subclinical hypothyroidism primarily include older people. Substantial evidence demonstrates that levothyroxine is not beneficial for patients 65 years and older. Symptoms suggesting hypothyroidism, such as fatigue and depression, are not improved with supplementation more than with placebo. Quality of life and body mass index are unchanged. Muscle strength and cognitive function are not enhanced. Harms such as cardiovascular events and mortality are not more frequent, although data suggest that larger studies may demonstrate these risks. With no benefit and concern for harm, the group recommends against treatme...
