Implications of low TSH levels

When the thyroid-stimulating hormone is low, this signifies hyperactivity of the thyroid gland, referred to as hyperthyroidism. In hyperthyroidism, the thyroid gland excessively produces thyroid hormones which will constantly send negative feedback to reduce TSH release from the pituitary gland.Many common conditions cause the thyroid gland to become overactive like Grave’s disease, inflammation of the gland itself, multimodal Goiter, or an adenoma growing. Sometimes it happens when hypothyroidism treatment is too harsh, requiring a dose reduction to be resolved. In less common cases, the excess of thyroid hormones is secondary to a tumor in the thyroid gland.Low TSH symptoms comprise weight loss, anxiety, tremors, tachycardia, bulging of the eyes, poor sleeping hygiene, hirsutism, menstruation disturbances, more frequent bowel activity, and enlarged thyroid gland upon palpation.If left untreated for a long time, hypothyroidism may cause heart problems like arrhythmias and atrial fibrillations which can have detrimental effects on health. It may also lead to osteoporosis, loss of vision, or even a thyrotoxic crisis which is a life-threatening emergency.
