Electrolyte imbalances occur when minerals like sodium, potassium, calcium, or magnesium in the blood become too high or too low, often affecting kidney function. Dr. Leena Joshi, a board-certified nephrologist serving Daly City and San Mateo County, evaluates electrolyte disorders through comprehensive blood work and kidney function tests. Dr. Joshi develops individualized treatment plans that may include dietary modifications, medication adjustments, and management of underlying kidney conditions to restore healthy electrolyte levels.
What is electrolyte imbalance?
Electrolytes are minerals in your blood and body fluids that carry an electric charge. These minerals include sodium, potassium, calcium, magnesium, chloride, and phosphate. Your body needs the right balance of these minerals to keep your heart beating, your muscles working, and your nerves sending signals. Your kidneys play a major role in keeping electrolytes balanced by filtering your blood and removing extra minerals through urine. When electrolyte levels become too high or too low, it can cause serious health problems. Many things can upset this balance, including kidney disease, certain medications, dehydration, or other medical conditions. Dr. Joshi helps patients in Daly City and throughout San Mateo County understand and manage these important mineral imbalances.
