For sure, if the surgical option is chosen to treat hyperthyroidism (Graves' disease), an overly aggressive thyroid ablation will lead to accidentally removing too many of the (usually) six parathyroid glands embedded within the thyroid tissue. Am currently researching the role of the pituitary feedback loop in generating hypocalcemia in the untreated hyperthyroid state (other than the incredibly rare event of a TSH-secreting pituitary adenoma).

actually hyperthyroidism causes weight loss while hypothyroidism causes weight gain. This is due to the hormones produced by the thyroid which regulate the storage of energy as fat in the body.
Hyperthyroidism (overactive thyroid) is a condition in which your thyroid glandproduces too much of the hormone thyroxine. Hyperthyroidism can accelerate your body's metabolism significantly. It causes what is called Grave's Disease.
Hypocalcemia
Hyperthyroidism.
Hypocalcemia can cause depression
The prognosis for correcting hypocalcemia is excellent. However, the eye damage that may result from chronic hypocalcemia cannot be reversed.
Citrate in blood binds to calcium ions, forming complexes that are not available for biological functions. This decreases the amount of free calcium in the blood, leading to hypocalcemia. Additionally, citrate can chelate calcium in the blood, further reducing the level of ionized calcium available for use in blood clotting and nerve function.
Graves disease, hyperthyroidism
Calcium supplements are useful primarily to treat hypocalcemia. This is a nutritional issue that typically arises around pregnancy. In dogs, pregnancy hypocalcemia tends to be pre-parturient (before birth) and causes a tonic paralysis (rigid paralysis). In dairy cattle, hypocalcemia tends to be post-paturient (after birth) and causes a flaccid paralysis (floppy or loose paralysis). In both cases, careful administration of intravenous calcium can reverse the paralysis in a matter of hours.
There are several different conditions that can cause calcium deposits in the eye. These include hypocalcemia, gout, renal failure, and chronic inflammation.
Hyperthyroidism is when the thyroid gland in the body is overactive. The symptoms this causes can range from palpitations and sweating, tremor in the hands, feeling anxious and tense a lot, losing weight even when eating normally.
