Causes of Electrolyte Imbalance in Cats: Common Reasons and Treatment Methods
Causes of Electrolyte Imbalance in Cats: Common Reasons and Treatment Methods
Electrolytes are compounds that conduct electricity when dissolved in water or in a molten state. They play a crucial role in a cat's body. When electrolyte levels are too high or too low, it can lead to a range of health problems. Cats absorb electrolytes through their food, which are then absorbed by the intestines and stored in different parts of the body (bones, soft tissues), divided into two components: intracellular fluid (ICF) and extracellular fluid (ECF).
Intracellular fluid is the fluid inside the cells. Extracellular fluid (ECF) is all the fluid outside the cells, consisting of plasma, interstitial fluid, and transcellular fluid. The main electrolytes include: sodium, potassium, magnesium, calcium, phosphate, chloride, and bicarbonate. When electrolyte levels rise or fall below safe levels, imbalances occur.
I. Sodium (Na), Normal Range: 147–156mEq/l
Most of the sodium in cats is found in the blood and the fluid surrounding the cells. Sodium is a positively charged ion (cation) that combines with chloride ions (negatively charged anions) to form sodium chloride. It primarily maintains the volume and balance of fluid inside and around the cells (osmosis), as well as maintaining muscle and nerve function.
Hypernatremia (high sodium levels): It is usually a complication of critically ill cats, who may not be drinking enough water or may have fluid loss due to vomiting and diarrhea. Excessive salt intake can also lead to hypernatremia. High blood sodium levels can lead to the movement of water from inside the cells, causing fluid to accumulate around the brain.
Symptoms: Increased thirst, confusion and disorientation, vomiting, diarrhea, hypothermia, slow capillary refill time, seizures, coma.
Hyponatremia (low sodium levels): Caused by water retention or fluid loss, such as vomiting, diarrhea, Addison's disease, and kidney failure, as the kidneys cannot eliminate excess fluid from the body.
Symptoms: Lethargy, weakness, nausea, vomiting.
II. Potassium (K), Normal Range: 4.0–4.5 mEq/l
Potassium is a cation (positively charged ion), with over 90% located inside the cells and the rest in the extracellular fluid of the blood. The kidneys excrete excess potassium through urine.
Function: Regulates nerve conduction, skeletal and smooth muscle contraction, maintains cell volume, regulates heartbeat, and helps maintain blood pressure and cell volume.
Hyperkalemia (high potassium levels): The kidneys are responsible for excreting excess potassium from the blood through urine. If they are no longer functioning efficiently, potassium levels can build up. The most common causes of hyperkalemia are reduced urine excretion due to kidney failure, urinary obstruction, bladder rupture, Addison's disease, and diabetic ketoacidosis, leading to potassium moving from cells into the bloodstream.
Symptoms: Arrhythmias, seizures, lethargy, muscle weakness, gastrointestinal disturbances, depression
Hypokalemia (low potassium levels): Can be caused by insufficient potassium intake, increased potassium excretion, or potassium moving from extracellular fluid into intracellular fluid. The most common causes are hypomagnesemia (reduced intracellular magnesium due to magnesium deficiency, releasing magnesium-mediated ROMK channel inhibition and increasing potassium secretion), increased potassium excretion due to vomiting or cats with chronic kidney disease or diabetes. Cats with chronic anorexia (lack of appetite) may have reduced food intake. Sodium bicarbonate, insulin, and glucose can push potassium from extracellular fluid into intracellular fluid.
Symptoms: Lethargy (decreased activity), weakness, muscle pain, stiff posture and gait, unwillingness to move, ventroflexion of the neck (inability to lift the head due to muscle weakness), increased thirst and urination (due to decreased kidney function), thinness, muscle atrophy, unkempt hair.
III. Magnesium (Mg), Normal Range: 1.9-2.8 mg/dL
Magnesium is a cation (positively charged ion) with 60% of the body's magnesium stored in the bones, the rest in muscles and soft tissues (39%), and only 1% in the extracellular fluid. It is the second most abundant intracellular cation (ion) after potassium.
Participates in the reactions of 300 enzymes in the body, including:
Maintaining normal nerve and muscle function
Maintaining a stable heartbeat, when calcium enters heart muscle cells, it stimulates muscle fiber contraction, magnesium counteracts this effect, helping these cells relax
Helping bone growth
Regulating blood sugar levels and blood pressure
Synthesis of fat, protein, nucleic acid and coenzyme
Magnesium is essential for the production and release of parathyroid hormone
Adenosine triphosphate (ATP) is the main energy source within cells and must be combined with magnesium ions to be biologically active
Clinically manifested in two forms:
Hypermagnesemia (high magnesium levels): This is rare in cats and is usually associated with kidney failure when the kidneys lose the ability to excrete excess magnesium from the body.
Symptoms: Nausea, vomiting, weakness, bradycardia (slow heart rate), depression, paralysis, obtundation, decreased respiration, hypotension, coma.
Hypomagnesemia (low magnesium levels): The most common causes of hypomagnesemia include malnutrition, poor diet quality, increased renal (kidney) excretion due to kidney disease, hyperthyroidism, diabetes, and diuretics.
Symptoms: Poor growth in kittens, irritability, anorexia, soft tissue calcium deposition, seizures.
IV. Calcium (Ca), Normal Range: 7.5–10.8 mg/dl
Calcium is a cation (positively charged ion) and is the most abundant mineral in the body. It is responsible for many essential functions. 99% of calcium is stored in the bones, the remaining 1% is stored in the blood.
Its functions:
Heart contraction function
Muscle contraction
Nerve impulses
Blood clotting function
Stabilize the permeability of cell membranes to sodium
Cell growth
Provide strength for teeth and bones
Several key factors such as parathyroid glands, vitamin D, calcitonin (a hormone), kidneys, and bones (store excess calcium) are responsible for regulating and maintaining calcium levels. Any problem with any of these factors can lead to either high or low calcium levels.
The two most common clinical symptoms:
Hypocalcemia (low calcium): Hypoparathyroidism, milk fever, chronic kidney failure, hypoproteinemia, phosphate enemas, vitamin D deficiency and antifreeze poisoning, acute pancreatitis, and diet.
Symptoms: Neuromuscular hyperexcitability (twitching, whisker twitching, facial rubbing, involuntary muscle contractions), lethargy, stiff gait, panting, increased respiratory rate, anorexia, fever, seizures
Hypercalcemia (high calcium): The most common cause of hypercalcemia is idiopathic (IHC), meaning no underlying cause is found. Most hypercalcemia is due to increased gastrointestinal intake from food or excessive mobilization of calcium stored in bones. Other causes include cancer, primary hyperparathyroidism, Addison's disease, ingestion of certain houseplants or rat poison, and vitamin A toxicity.
Symptoms: Anorexia, polydipsia and polyuria, weight loss, weakness, neuromuscular disease, gastrointestinal disturbances, seizures, convulsions; calcification of tissues, especially the heart and kidneys.
V. Phosphate (PO4), Normal Range: 3.3–7.5 mg/dl
Phosphate is an anion (negatively charged ion) that combines with calcium to form the hard structure of bones and teeth. 85% of phosphate is stored in the bones, the rest is located in the cells and extracellular fluid.
Calcium and phosphate levels are similar and are controlled by several mechanisms, including parathyroid glands, vitamin D, kidneys, and calcitonin hormone. The kidneys excrete excess phosphate from the body through urine and feces.
Its main functions:
Combining with calcium to form and repair bones and teeth
Phosphate is a component of important cell substances, including cell energy, cell membranes, and DNA (deoxyribonucleic acid)
Plays a role in regulating protein, fat, and carbohydrate metabolism
Involved in nerve function
Involved in vitamin D activation and calcium homeostasis
Clinical manifestations:
Hypophosphatemia (low phosphorus): This is rare in cats and occurs when extracellular phosphate is redistributed to intracellular fluid.
Symptoms: Lethargy, irritability, joint stiffness, weakness.
Hyperphosphatemia (high phosphorus): The most common cause of hyperphosphatemia is kidney disease, as the kidneys' ability to clear excess phosphate decreases. Phosphate enemas can also lead to elevated blood levels. When levels increase, phosphate binds to calcium, leading to a decrease in calcium levels.
Symptoms: Neuromuscular hyperexcitability (twitching, whisker twitching, facial rubbing, involuntary muscle contractions), lethargy, stiff gait, panting, increased respiratory rate, anorexia, fever, seizures.
VI. Chloride (Cl), Normal Range: 111–125 mEq/l
Chloride is an anion (negatively charged ion) that is usually combined with sodium in the form of salt and is the most abundant anion in the extracellular fluid. Chloride is closely related to sodium and potassium, helping to maintain fluid balance in the body.
Its main functions are to maintain blood pressure and produce gastric acid.
Hypochloremia (low chloride levels): The most common cause of hypochloremia is prolonged vomiting and diarrhea.
Symptoms: Dehydration, tachycardia (fast heart rate), lethargy.
Hyperchloremia (high chloride levels): Hyperchloremia can be caused by fluid loss, such as prolonged vomiting and diarrhea, high blood sodium levels, kidney failure, and some medications (corticosteroids and diuretics).
Symptoms: Hypertension, muscle weakness, irregular heartbeat, seizures.
Diagnosis of Electrolyte Imbalance in Cats
Trying to diagnose or treat electrolyte imbalances in cats at home is unwise, as there are many causes and types of electrolyte imbalances. A cat may have an underlying condition and electrolyte imbalance is just a symptom. In this case, the electrolyte disturbance will not be fully resolved until the underlying condition is addressed. Therefore, a veterinarian needs to perform laboratory diagnostics to confirm the underlying cause:
Physical Examination: First, check the pet's heart rate, respiratory rate, skin, fur, eyes, and reflexes to rule out other diagnoses or determine the severity of the cat's condition.
Blood Biochemical and Blood Gas Tests: The cat will need a complete blood biochemistry and blood gas test to determine which electrolytes are out of balance. Blood samples are drawn to detect potential kidney disease or anemia causing electrolyte imbalances.
Urine Analysis: Urine samples can also be collected and analyzed for their electrolyte content.
Imaging Studies (X-rays and Ultrasound): Depending on the cat's symptoms and laboratory results, ultrasound, radiographs, or X-rays may be performed to determine if any underlying conditions are causing the electrolyte imbalance.
Treatment of Electrolyte Imbalance in Cats
First, correct electrolyte imbalances: Depending on the severity of the cat's electrolyte imbalance, hospitalization may be required. In a hospital setting, fluids or intravenous fluids and electrolyte supplementation can be administered easily and painlessly to your cat. Once your cat is stable, a maintenance dose may be required to prevent recurrence of electrolyte imbalances.
Second, determine the cause of the electrolyte imbalance in your cat and take further steps to treat any underlying conditions in your cat. For example, if your cat has kidney disease, it may need medication or dialysis. If your veterinarian determines that your cat has diabetes, treatment may be required to lower blood sugar levels.
Finally, if your cat has a simple electrolyte imbalance that is not caused by an underlying health condition, corrective treatment and education on how to prevent another event may be something to keep in mind. Recovery for these cats is often quick, and management is a matter of observing and encouraging (or preventing) water intake and urine output. Cats seem to make a full recovery after veterinary treatment, but it is very important to respect all follow-up checkups and appointments. For more complex electrolyte imbalance cases, such as diabetes or kidney disease, recovery and treatment will depend on a range of other factors.
Summary of Experiences
Electrolyte imbalance in cats is a complex health problem that requires professional veterinary diagnosis and treatment. If your cat exhibits any of the following symptoms, please contact your veterinarian immediately:
Vomiting or diarrhea
Lethargy or weakness
Loss of appetite
Increased thirst or urination
Muscle weakness or tremors
Difficulty breathing
Early detection and treatment of electrolyte imbalances in cats can prevent the development of serious complications and ensure the cat's health.
