Postpartum hypothyroidism is a common condition concerning females immediately after having a baby that's brought on by an autoimmune disorder referred to as lymphocytic thyroiditis. It affects around 5% of females after childbirth and is thought to be the main reason for postpartum depression.
In lymphocytic thyroiditis, the thyroid glands becomes swollen because of the infiltration of a white blood cell called lymphocyte. It is thought to be a consequence of the modification of the immune system necessary for pregnancy. It has an initial hyperthyroid period wherein the thyroid glands releases abnormal amounts of thyroid hormones, leading to a serious increase in the metabolism rate. This will result in diarrhea, rapid pulse, feeling overheated, rapid weight loss, difficulty in sleeping, and anxiety.
After the initial hyperthyroid phase, the thyroid either reverts to its regular state or it goes into hypothyroid stage. In this status, the thyroid glands become underactive, making not enough thyroid hormones that triggers an irregular decrease in the metabolism rate. It results in weakness among new mothers, wherein they will be slumbering a minimum of 14 hours and awaken unrefreshed. This also makes the new mother acquire more pounds even though she's following a thorough diet and workout strategy. This is because her body cannot correctly process the excessive calories because of the alterations in metabolic rate. These symptoms can seriously impact the psyche of the new mother, possibly causing a postpartum depressed state indicated by feelings of sadness, anxiety, feelings of guilt and worthlessness, a sense of hopelessness, disturbance in appetite, mood swings and lack of interest in the baby.
Pregnant women who tested positive for antithyroid antibodies have between 33% to 50% odds of obtaining lymphocytic thyroiditis after giving birth to the baby. Furthermore, several researchers have discovered that the existence of these antibodies makes a pregnant woman three times more prone to obtain postpartum depression. This thyroid condition following pregnancy may be temporary, lasting for up to 6 months to a year. However, roughly one in five of women will develop long term hypothyroidism that requires life long hormone therapy. The reason being the thyroid glands were too impaired because of the hormonal imbalance or because the pregnancy set off an underlying condition of autoimmune disease.
