6. Infertility
Hypothyroidism disrupts the ovulation cycles of females, affecting fertility by disrupting regular cycles. Furthermore, hormonal imbalances can cause women to experience heavier than usual or irregular menstrual cycles.
7. Goiter
The thyroid gland is a butterfly-shaped gland at the front of the neck. The neck area is where a goiter can form in cases of iodine deficiency. A goiter is one of the earliest signs of hypothyroidism because the thyroid gland swells in response to constant stimulation to produce more hormones. The body also tries to enlarge the thyroid gland so it will be able to absorb more iodine. Typically, a goiter is not a problem, but if it becomes too enlarged it can cause breathing and swallowing difficulties.
8. Heart complications
A typical symptom of hypothyroidism is a slow heart rate. Thyroid hormones directly affect body temperature and heart rate regulation. If thyroid levels are lacking, the body can't regulate the heart rate effectively. A slow heart rate, or bradycardia, can cause symptoms such as dizziness, nausea and fainting. Chronic hypothyroidism can lead to high levels of LDL (bad) cholesterol. High cholesterol increases one's risk of heart attacks, heart disease and heart failure.
9. Hair, skin and nail problems
Thyroid hormones support the growth of hair, skin and nails. The lack of these hormones commonly causes the skin to become dry, pale and itchy. The nails and hair can become dry, thin and brittle. A decrease in metabolism further hinders skin, hair and nail health as the amount of nutrient-rich blood delivered to the body is insufficient.
