Even if small amounts are ingested over long periods of time, the prolonged high levels of calcium ions have large negative effects on the animals. [30] The issues these animals experience are muscle weakness, and calcification of blood vessels, heart valves, liver, kidneys, and other soft tissues, which eventually can lead to death. [30]
Muscle weakness; Metastatic calcification of the soft tissues; Insomnia; Symptoms of vitamin D toxicity appear several months after excessive doses of vitamin D are administered. In almost every case, a low-calcium diet combined with corticosteroid drugs will allow for a full recovery within a month.
Muscle pains, weakness, vomiting, confusion, tea-colored urine, irregular heartbeat [3] [4] Complications: Kidney failure, high blood potassium, low blood calcium, disseminated intravascular coagulation, compartment syndrome [3] Causes: Crush injury, strenuous exercise, medications, substance use, certain infections [3] Diagnostic method
People often have few or no symptoms. [1] They may get occasional muscular weakness, muscle spasms, tingling sensations, or excessive urination. [1] High blood pressure, manifestations of muscle cramps (due to hyperexcitability of neurons secondary to low blood calcium), muscle weakness (due to hypoexcitability of skeletal muscles secondary to hypokalemia), and headaches (due to low blood ...
Its causes are many and can be divided into conditions that have either true or perceived muscle weakness. True muscle weakness is a primary symptom of a variety of skeletal muscle diseases, including muscular dystrophy and inflammatory myopathy. It occurs in neuromuscular junction disorders, such as myasthenia gravis. Muscle weakness can also ...
Spastic hypertonia involves uncontrollable muscle spasms, stiffening or straightening out of muscles, shock-like contractions of all or part of a group of muscles, and abnormal muscle tone. It is seen in disorders such as cerebral palsy, stroke, and spinal cord injury. Rigidity is a severe state of hypertonia where muscle resistance occurs ...
Corticosteroids often cause muscle weakness to some degree in patients. Symptoms are usually weakness of the proximal muscles, neck flexor, and in extreme cases, respiratory muscle weakness can also occur. [1] Corticosteroids have not only been found to cause some degree of muscle atrophy, but also a local or diffuse cell death.
Hyperkalemia is an elevated level of potassium (K +) in the blood. [1] Normal potassium levels are between 3.5 and 5.0 mmol/L (3.5 and 5.0 mEq/L) with levels above 5.5 mmol/L defined as hyperkalemia. [3] [4] Typically hyperkalemia does not cause symptoms. [1] Occasionally when severe it can cause palpitations, muscle pain, muscle weakness, or ...
