Can thyroid meds hurt your liver?

A frequent treatment for hyperthyroidism is antithyroid medications, either Methimazole or Propylthiouracil. It is known that both medications, as well as hyperthyroidism itself, can affect the function of the liver, causing increases in blood levels of markers of liver function know as liver function tests.

What does thyroxine do to the liver?

Thyroxine and tri-iodothyronine are essential for normal organ growth, development and function. These hormones regulate the basal metabolic rate of all cells, including hepatocytes, and thereby modulate hepatic function; the liver in turn metabolizes the thyroid hormones and regulates their systemic endocrine effects.

How do you know if your taking too much levothyroxine?

What do elevated liver enzymes mean?

Elevated liver enzymes often indicate inflammation or damage to cells in the liver. Inflamed or injured liver cells leak higher than normal amounts of certain chemicals, including liver enzymes, into the bloodstream, elevating liver enzymes on blood tests.

Can hyperthyroidism cause fatty liver disease?

From Rotterdam Study, the prevalence of NAFLD was 21.5% in hyperthyroidism subjects, and a decreasing trend of NAFLD prevalence was found in different thyroid status from hypothyroidism, euthyroidism to hyperthyroidism [20]. NAFLD risk decreased gradually from hypothyroidism to hyperthyroidism.

What causes fatty liver?

Eating excess calories causes fat to build up in the liver. When the liver does not process and break down fats as it normally should, too much fat will accumulate. People tend to develop fatty liver if they have certain other conditions, such as obesity, diabetes or high triglycerides.
