Can Drinking Too Much Water To Get Hydrated For A
Question: can drinking too much water to get hydrated for a blood test lower your sodium blood levels
Brief Answer:
Drinking plenty of water may reduce sodium levels in blood
Detailed Answer:
Hello and welcome at "Ask a Doctor" service,
Drinking too much water can cause reduced sodium levels in blood. If you had tests done and sodium level was lower than the normal value for the lab, this may be due to the fact that you have been drinking a lot of water.
On the other hand there are other causes for low sodium as well like due to some medications or certain medical conditions. To make sure of the cause of low sodium it might be advisable to repeat the test (avoiding drinking plenty before the test).
I hope this answers your query. Let me know if I can assist you further.
