Low Serum Potassium (Hypokalemia)
Hypokalemia is a condition in which the dog has low serum potassium. It is a metabolic cause of generalized muscle weakness.
The dog will experience weakness.
Loss of potassium occurs with severe vomiting. It also occurs with the long term use of diuretics that cause the kidneys to excrete potassium, such as Lasix (furosemide). Other causes of hypokalemia include bloat, diabetic ketoacidosis, and Cushing's syndrome.
The diagnosis is made by measuring serum potassium levels.
Weakness disappears as potassium is replaced and the underlying cause is corrected. Close veterinary supervision is required until normal levels are restored.
There is no prevention for this condition.
Please contact your veterinarian with questions regarding this condition.
