Because your nervous system is overstimulated, you may notice you have a harder time falling asleep at night. Even if you feel tired, your metabolism is still running high and may prevent you from falling and staying asleep. You may also experience night sweats, restlessness, and leg tremors.
EYE IRRITATION OR PROBLEMS
This usually occurs in patients with Graves’ disease. Symptoms include feeling of irritation or grittiness in the eyes, redness or inflammation of the white part of the eyes, dry eyes, swelling of the eyelids, sensitivity to light, bulging of the eyes, and double vision.
SENSITIVITY TO HEAT
People with hyperthyroidism will become hot easily due to excess thyroid hormones. Your metabolism increases, leading to a rise in body temperature.
SYMPTOMS OF HYPOTHYROIDISM
If you feel exhausted all the time, even after getting adequate sleep, you might have hypothyroidism. Fatigue occurs because your body doesn’t produce enough thyroid hormone, which helps give you energy. Though fatigue can be a symptom of many different disorders, it’s worth getting checked out if you also have other symptoms on this list.
WEIGHT GAIN/INABILITY TO LOSE WEIGHT
According to the American Thyroid Association, people with hypothyroidism generally present with weight gain or a hard time losing weight. However, in most people, only 5-10 pounds of weight gain is attributable to the underactive thyroid. Most of the excess weight gained by people with hypothyroidism is due to the accumulation of water and salt.
People with this condition have a low BMR (basal metabolic rate), which makes it much easier to gain weight. Low energy levels lead to less calories burned by the body, meaning that even eating a small amount can result in weight gain. Also, since the metabolism is damaged, those with this condition will have a hard time losing weight as well.
