Hyponatremia
Definitions
Description
A condition that occurs when the level of sodium in the blood is too low.
Overview
Sodium helps regulate the amount of water that's in and around cells. In hyponatremia, the level of sodium in the blood is too low. This causes the body's water level to rise, and cells begin to swell. This swelling can cause many health problems, from mild to life-threatening conditions.
Symptoms
Symptoms include nausea, headache, confusion and fatigue. In serious cases, seizures can occur.
Treatments
Treatment is aimed at addressing the underlying cause, if possible. Limiting fluid intake and medicines to treat nausea and headaches can help. In more-serious cases, hospitalization for treatment to slowly raise the sodium levels in the blood may be needed.
