Hyperaldosteronism is one of the most common adrenal gland disorders in cats, yet it is frequently underdiagnosed, often masked by corresponding kidney disease (Kooistra, 2015). Sodium passively moves across the capillary membrane, and its concentration rapidly equilibrates between the interstitial and plasma fluid compartments. The most common cause of hypercalcemia is idiopathic (IHC), which means no underlying cause can be found. He is a pure bred persian about 3 years oldish. It is the role of the kidneys to remove excess potassium from the blood via the urine if they are no longer functioning as efficiently potassium levels can build up. Regulatory mechanism abnormalities leading to this life-threatening complication include inadequate ADH production or release from the neurohypophysis or posterior pituitary (central diabetes insipidus), failure of the renal collecting duct cell to recognize and respond to ADH (nephrogenic diabetes insipidus), or a combination of both. However, dietary sodium restriction may still be warranted to help reduce oxidative stress and sodium retention in feline kidney patients. is decreased urinary excretion due to kidney failure, urinary tract blockages, ruptured bladder, Addison’s disease and diabetic ketoacidosis which causes potassium to move from the cells and into the blood circulation. New York, McGraw-Hill. Hypoparathyroidism, milk fever, chronic kidney failure, hypoalbuminemia, phosphate enemas, vitamin D deficiency and antifreeze poisoning, acute pancreatitis and diet. ACTIONS:Acidosis is a result of an elevated concentration of hydrogen ions in the body fluids, which can result from three conditions. Hypernatremia in cats is defined as an elevation in blood sodium levels above normal values (>155 mEq/L). Causes: It commonly occurs as a result of decreased urinary excretion, which may be due to kidney disease, urinary blockages, ruptured bladder, Addison’s disease and reperfusion injury. Chloride works closely with sodium and potassium and helps to keep fluid levels in the body balanced. Reduced baroreceptor stretch caused by hypo­volemia and hypotension also results in stimulating the thirst center. This can cause many symptoms such as lethargy and weakness. Nonetheless, high sodium levels are used to enhance water intake and urine volume, with … Healthy kidneys perform many important functions, most notably filtering the blood and making urine, so problems with kidney function can result in a variety of health problems for a cat. Excess ingestion of salt can also cause hypernatremia. The most common cause of hyperkalemia is decreased urinary excretion due to kidney failure, urinary tract blockages, ruptured bladder, Addison’s disease and diabetic ketoacidosis which causes potassium to move from the cells and into the blood circulation. BUN, however, is freely permeable across all membranes. As a result, excess sodium can manifest as a number of seemingly unrelated symptoms, such as: Excessive thirst Lethargy Poor appetite Weakness Seizures Behavior changes Internal bleeding Ventral neck flexion (inability to raise the head due to muscle weakness), Magnesium is a cation (positive charged ion), 60% of the magnesium in the body is found in bone, while the rest is in muscles, soft tissues (39%), only 1% is located in the extracellular fluid. Phosphorus In general, most kitties with CKD need to be eating low phosphorus type of food. I have 5 cats. Water is lost continuously through evaporation from the respiratory tract and cellular metabolism (called sensible water loss) and in normal production of body fluids (e.g., urine, feces, mucus). A high sodium level in the blood is most commonly caused by fluid losses through sweating, diarrhea or excessive urination, according to the Cleveland Clinic. It is responsible for many essential functions. This page was last edited on 10 September 2010, at 00:23. Few reports pertain to symptomatic hypernatremia in cats. Three of the cats were humanely euthanized because of continued neurologic deterioration, and one recovered after 10 weeks of supportive care. Phosphate is an anion (negatively charged ion) combines with calcium to form the hard structure of the bones and teeth. This condition is rare in cats and can occur when extracellular phosphate is redistributed into the intracellular fluid.
