4. THINNING OF YOUR HAIR
An overactive or underactive thyroid affects your hair growth cycle. Whereas most of your hair grows, a small part of it rests, thereby making your hair appear thinner.
5. SWEATING AT RANDOM TIMES
Unusual excessive sweating is a sign of a hyperactive thyroid. Abnormally high hormone levels can accelerate your metabolism, thereby making you feel overly warm.
6. A SURPRISING WEIGHT GAIN
Inexplicable weight gain is normally a manifestation of an underactive thyroid. Lack of hormones lowers metabolism and calorie burning.
