Secondary hyperparathyroidism typically occurs due to vitamin D deficiency, chronic kidney disease, or other causes of low blood calcium. [1] The diagnosis of primary hyperparathyroidism is made by finding elevated calcium and PTH in the blood. [2] Primary hyperparathyroidism may only be cured by removing the adenoma or overactive parathyroid ...
Hyperparathyroidism was first described in 1925 and the symptoms have collectively become known as "moans, groans, stones, and bones." By far, the most common symptom is fatigue, but depression, memory loss, and bone aches are also very common. Primary hyperparathyroidism is relatively more common in postmenopausal women.
Primary hyperparathyroidism (or PHPT) is a medical condition where the parathyroid gland (or a benign tumor within it) produce excess amounts of parathyroid hormone (PTH). The symptoms of the condition relate to the resulting elevated serum calcium ( hypercalcemia ), which can cause digestive symptoms, kidney stones , psychiatric abnormalities ...
Diplopia (double vision) is common. [4] Limitation of eye movement (due to impairment of eye muscle function). Periorbital and conjunctival edema (accumulation of fluid beneath the skin around the eyes). In severe cases, the optic nerve may be compressed and acuity of vision impaired. [24] Occasionally loss of vision.
Blurred vision is an ocular symptom where vision becomes less precise and there is added difficulty to resolve fine details. Temporary blurred vision may involve dry eyes, eye infections, alcohol poisoning , hypoglycemia , or low blood pressure .
Tertiary hyperparathyroidism is a condition involving the overproduction of the hormone, parathyroid hormone, produced by the parathyroid glands. [1] The parathyroid glands are involved in monitoring and regulating blood calcium levels and respond by either producing or ceasing to produce parathyroid hormone.
Secondary hyperparathyroidism can also result from malabsorption (chronic pancreatitis, small bowel disease, malabsorption-dependent bariatric surgery) in that the fat-soluble vitamin D can not get reabsorbed. This leads to hypocalcemia and a subsequent increase in parathyroid hormone secretion in an attempt to increase the serum calcium levels.
In mild disease, patients present with eyelid retraction. In fact, upper eyelid retraction is the most common ocular sign of Graves' orbitopathy. This finding is associated with lid lag on infraduction (Von Graefe's sign), eye globe lag on supraduction (Kocher's sign), a widened palpebral fissure during fixation (Dalrymple's sign) and an incapacity of closing the eyelids completely ...
