Hypothyroidism - Symptoms of underactive thyroid
NHS Choices Medical Reference
Symptoms of hypothyroidism tend to come on slowly, and you may not notice them for several years.
Possible early symptoms
- being sensitive to cold,
- slowness in body and mind,
- muscle aches and weakness,
- muscle cramps,
- dry and scaly skin,
- brittle hair and nails,
- heavy or irregular periods, and
- weight gain.
The elderly may develop memory problems and/or depression. Children may have restricted growth.
Late symptoms (if left untreated)

Later symptoms include:
- a low-pitched and hoarse voice,
- dull facial expressions and a puffy-looking face,
- thinned (or partly missing) eyebrows,
- a slow heart rate,
- deafness, and
