6. Low Sex Drive
Loss of libido, especially in women, has also been linked to thyroid problems. Hypothyroidism, in particular, is known to be responsible for a low sex drive. When the thyroid gland produces low levels of hormones, metabolism and other bodily functions are slowed down. The reproductive organs are slower in response, as are the adrenal glands, which produce the sex hormones. These changes may lead to a temporary disinterest in sexual activity; however, once thyroid hormone replacement begins, individuals can expect their libido to normalize. Patients with hyperthyroidism rarely exhibit loss of libido; in some cases, in fact, the sex drive may be enhanced.
