Hypoparathyroidism can be caused when the parathyroid glands are damaged or ischemic, mostly due to thyroid surgery mishap or due to some autoimmune disease. When a large amount of blood calcium enters the bones causing hypocalcemic convulsions, it can be temporary or untreated for months and years. Due to increased neuromuscular stress, the most obvious manifestation is hand-foot tics. Due to increased neuromuscular stress, the most obvious manifestation is hand-foot tics, which will return to normal when the primary disease is treated along with good calcium supplementation. In the early stage of the disease, there are only abnormal sensation, tingling and numbness in the limbs, hand and foot spasms and stiffness. When the blood calcium decreases to a certain level, twitchy symptoms often appear, and the fingers of both hands are flexed inward to form an eagle’s claw shape, after which the feet also show tonic extension. In severe cases, the skeletal muscles and smooth muscles of the whole body may also be in spasm, and laryngospasm and bronchospasm may occur, resulting in asthma, laryngeal tinnitus, asphyxia, apnea and other critical signs. The main method of treatment for parathyroid disease is to supplement calcium and vitamin D. A diet high in calcium and low in phosphorus is recommended, and not more dairy products, egg yolks, cauliflower and other foods. If the seizure is mild, 2-3 grams of calcium lactate should be taken orally every day. Severe patients should go to the hospital in order to differentiate from neurosis, epilepsy and idiopathic somatic easy spasms to avoid getting the symptoms wrong. It is important to enhance the body’s resistance to avoid upper respiratory tract infections and pharyngitis to prevent the occurrence of this disease, subacute thyroiditis is a self-limiting disease can be self-remitting, but a significant number of patients need treatment because of the obvious symptoms.
