8. Menstrual irregularities
Statistics show that women are more likely than men to have hypothiroidism. Even if the age of the highest incidence for women is over 60 years old, many women in their fertile years live with low thyroid hormone levels. If this is the case, they might experience menstrual alterations that are a result of their hypothyroidism.
Women with low thyroid hormone levels tend to have more irregular periods. The duration of the bleeding as well as the distance between the beginning of one period and the beginning of the next one might vary from month to month and even some periods might get skipped completely.
Another possible consequence of hypothyroidism in women is abundant bleeding, much heavier than normal. The main disadvantage of heavy periods is that they dehydrate the body and lower the erythrocyte count, increasing the likeability of having fatigue and anemia due to blood loss.
