Heavy Periods Are One Of Many Thyroid Symptoms
Abnormal thyroid hormone levels cause menstrual irregularities in women, and when levels are too low, the heavy periods a woman experiences may be indicative of hypothyroidism.
Talk to your doctor
In hypothyroidism, ovulation does not occur. Without ovulation, the endometrium sheds and causes excessive bleeding. Women often report heavy flow as one of their thyroid symptoms.
If you are suffering from heavy periods, it is a good idea to get your thyroid checked.
