Hypothyroidism and Pregnancy

Hypothyroidism can occur during or after pregnancy can also affect a woman’s ability to become pregnant.

Unfortunately many of the symptoms of hypothyroidism are masked by symptoms of pregnancy such as fatigue, weight gain and abnormal menstruation, and as a result, the disease is diagnosed or treated. Furthermore, the risk of developing hypothyroidism increases with age, which is significant because more and more women are delaying pregnancy until they are older.

Hypothyroidism can affect pregnancy in several ways:

  • You can be the cause of infertility because it prevents the production of eggs, anovulation, and therefore, there can be no fertilization.
  • Irregularities in the menstrual cycle.
  • Increased prolactin, a hormone that normally stimulates milk production after calving. Excess prolactin in the absence of pregnancy can prevent ovulation.
  • Pregnant women with hypothyroidism have an increased risk of spontaneous abortion about four times higher than normal. It is therefore important to find a possible hypothyroidism before pregnancy or very early stage.
  • You can prevent the fertilized egg appears to thrive and early menstruation, which might actually be an abortion.
  • Untreated hypothyroid pregnant women are at risk of developing hypertension or preterm delivery.
  • Babies of untreated hypothyroid mothers may not reach full intellectual development.
