Can lithium affect your thyroid?

Lithium use is associated with an increased risk of hypothyroidism. Many drugs can affect thyroid function. One in particular, Lithium, has been associated with developing goiter, hypothyroidism and hyperthyroidism.

Why does lithium affect the thyroid?

Lithium is concentrated by the thyroid and inhibits thyroidal iodine uptake. It also inhibits iodotyrosine coupling, alters thyroglobulin structure, and inhibits thyroid hormone secretion. The latter effect is critical to the development of hypothyroidism and goiter.

Can lithium induced hypothyroidism be reversed?

Although lithium-induced hypothyroidism is usually reversible upon cessation of lithium, the development of hypothyroidism is not a contraindication to continuing lithium, and most experts advocate thyroid augmentation therapy.

Does lithium increase TSH?

The inhibition of thyroid hormone secretion that occurs during lithium treatment results in decreased serum T4 and T3 concentrations, a compensatory increase in pituitary secretion of TSH and, in a new steady state, secretion of a normal amount of thyroid hormone by an enlarged thyroid gland [2].

Can lithium cause thyroiditis?

Lithium has long been known to affect thyroid function. Lithium decreases production of T4 and T3 and commonly causes hypothyroidism. More rarely, lithium causes hyperthyroidism due to thyroiditis. The patient’s history of low TSH for several years was not consistent with lithium-induced thyroiditis.

Can thyroid problems cause bipolar?

In conclusion, even though both hyperthyroidism and hypothyroidism are associated with changes in mood, overt bipolar disorder is uncommon in thyroid dysfunction.

How do you manage lithium induced hypothyroidism?

Does lithium affect your eyes?

Lithium, one of the oldest mood stabilizers, has been reported to cause eye irritation during the first few weeks of treatment. A potential etiology may be an increased sodium concentration in lacrimal secretion due to lithium’s effects on sodium-chloride cotransport proteins.

Why does lithium cause weight gain?

Reduced thyroid function, or hypothyroidism,4 is a well-known potential complication of long-term lithium treatment. This condition leads to a reduced metabolic rate, which in turn leads to weight gain.

What are the long term side effects of taking lithium?

The most concerning side effects of long term lithium use are hypothyroidism and kidney problems. According to a 2015 review article , these side effects are most likely to affect women below the age of 60 years. They are also more common among people with higher-than-average concentrations of lithium in the blood.

Can you take iodine with lithium?

These observations suggest that lithium and iodine can act synergistically to produce hypothyroidism and that the combined use of these agents should be avoided.

Can lithium cause thyroid nodules?

Lithium treatment has not been associated with thyroid tumours, apart from nodular goitre. In our cohort with at least 6 years of lithium treatment, ultrasound revealed nodules in 47% of women and 24% of men [8]. Similar prevalence rates have been found in the Sardinian general population (to be published).

Does lithium cause high calcium?

Long-term use of lithium is a known risk factor for hypercalcemia often due to involvement of the parathyroid gland. Because of this, lithium-induced hypercalcemia typically occurs simultaneously with abnormal parathyroid hormone concentrations.
