The main symptoms of hypothyroidism are fatigue and weight gain, as stated by Mayo Clinic. Many patients mistake this for getting older or not eating a proper diet, and hypothyroidism goes overlooked for quite some time.
Hypothyroidism is when the thyroid of a person is not working to its full capability and doesn't excrete the amount of hormones it should. Some of the other symptoms of hypothyroidism include a slower than normal heart rate, pain and stiffness in the joints, a swollen face, dry skin and an increased sensitivity to the cold. Hypothyroidism is also known to cause depression and loss of memory in some patients, according to Mayo Clinic.
