Recenti Prog Med. Feb;(2) doi: / [ Relationship between hypothyroidism and cholesterol out of the records of patients]. Studies were carried out on cholesterol metabolism in 11 nonobese patients and 16 obese patients with hypothyroidism and 13 with hyperthyroidism. An over- or underactive thyroid can affect your cholesterol levels. Speak with your doctor if you have symptoms of hyper- or hypothyroidism.

The main lipoprotein bundles are: HDL is so-called because there is a high cholesterol to protein ratio. It is also known as "good" cholesterol because it helps the body get rid of cholesterol from the blood.

Thyroid problems and cholesterol: What's the link?

LDL features a low cholesterol to protein ratio. It is also known as "bad" cholesterol. Higher LDL rates indicate a higher risk of heart disease. Although dietary causes in those predisposed to it may cause a buildup of bad cholesterol in the blood, it may also arise from some medical conditions, including thyroid disorders.

Understanding the link between the thyroid and cholesterol The link between the thyroid and cholesterol can result in conditions affecting each of them: Can an underactive thyroid cause high cholesterol?

Thyroid hormones, especially T3, play an essential role in helping the liver process and remove any excess cholesterol from the body. When the body does not produce enough thyroid hormones, the liver cannot process as much cholesterol as it should. An underactive thyroid means that the body removes less "bad" cholesterol from the blood than it should, which often leads to high levels of "bad" and total cholesterol. According to research, up to 13 percent of people with high blood cholesterol also have an underactive thyroid.

Thyroid/cholesterol

The same research notes that societies, such as the American Association of Clinical Endocrinologists and the American Thyroid Association, recommend that people newly-diagnosed with high cholesterol get tested for an underactive thyroid. The research also suggests that a person's cholesterol levels may improve once they have received treatment for an underactive thyroid, even if they do not require cholesterol-lowering medications.

Even mildly low thyroid hormone levels subclinical hypothyroidism can lead to high cholesterol. A high normal TSH level is associated with an atherogenic lipid profile in euthyroid non-smokers with newly diagnosed asymptomatic coronary heart disease.

Lipids Health Dis ; Wang F et al. Thyroid-stimulating hormone levels within the reference range are associated with serum lipid profiles independent of thyroid hormones. J Clin Endocrinol Metab ; Epub June 22, The study by Wanjia and colleagues looked at patients recently diagnosed with heart disease, while the study by Wang and colleagues looked at patients who were seen for a routine medical visit.

Cholesterol metabolism in hypothyroidism and hyperthyroidism in man.

Both studies consisted only of patients who were not taking any medications nor had health problems that could impact the TSH, thyroid hormone or cholesterol tests. Both studies reported that patients with TSH levels at the upper limit of the normal range thus with normal thyroid hormone levels were more likely to have higher cholesterol levels as compared with those with lower TSH levels.

It was previously known that thyroid hormone levels affect cholesterol levels.
