Symptoms usually come on gradually, over weeks or months. Therefore, you may have hypothyroidism for a long time, even years, before you realize you are ill. If you are an older adult, it may be even harder to recognize you are ill because instead of getting the typical symptoms of hypothyroidism, you may just gain weight or feel tired. Symptoms vary with the severity of the hypothyroidism and the length of time your body has lacked the proper amount of thyroid hormone.
Enlargement of the thyroid gland, called goiter (this is not always present)
Fullness in the neck
Difficulty swallowing; this can happen if the goiter is very large
Diffuse swelling of the skin and tissue around the eyes
Slow heart rate
Hypothermia (low body temperature)
Shortness of breath during exertion or when lying flat
Lethargy and mental decline
You may have only one of these symptoms, but usually patients have a combination. Occasionally, patients with hypothyroidism have no symptoms at all, or the symptoms are so subtle they go unnoticed for a long period of time.
