4. Hair Loss and Dry Skin
Thyroid hormones help maintain healthy skin and hair.
When levels become abnormal, people may notice:
Dry or rough skin
Thinned hair
Hair loss
Brittle nails
These symptoms are especially common in hypothyroidism.
5. Sensitivity to Cold or Heat
The thyroid regulates body temperature.
Symptoms may include:
Feeling unusually cold (hypothyroidism)
Heat intolerance and excessive sweating (hyperthyroidism)
These temperature sensitivities occur because metabolism is directly influenced by thyroid hormones.
6. Digestive Changes
Thyroid dysfunction can affect digestion and bowel movements.
Common signs include:
Constipation when metabolism slows
Diarrhea when metabolism speeds up
This happens because thyroid hormones influence intestinal activity.
7. Heart Rate Changes
Thyroid hormones help regulate the cardiovascular system.
Possible symptoms include:
Slow heart rate in hypothyroidism
Rapid heartbeat or palpitations in hyperthyroidism
These changes can affect overall cardiovascular health.
