Symptoms of low sodium levels in the body include abdominal pain or cramping, bloating, body aches, mood changes, dizziness and headaches. Additional symptoms are difficulty with memory or thinking, impaired balance, lethargy, muscle spasms and nausea. The medical term for this condition is hyponatremia, explains Healthgrades.
Additionally, there are serious symptoms associated with hyponatremia, which may be life threatening. These symptoms include changes in personality or behavior, chest pain or pressure, confusion or a loss of consciousness, and dizziness or vertigo. Muscle twitching or seizures, vomiting, gradual difficulty with walking and talking, memory loss, and weakness in the extremities are other symptoms that may be life threatening. If an individual experiences or observes any of these symptoms, he should seek immediate medical attention by calling 911, directs Healthgrades.
Common causes of hyponatremia include diarrhea, excessive sweating and vomiting. Certain medical conditions, such as adrenal gland disease, burns, scarring of the liver, dehydration and extreme exercise, may also cause hyponatremia, according to Healthgrades. Risk factors that are associated with the development of hyponatremia include aging, hot climate, kidney disease, liver failure and side effects from medications. Staying properly hydrated and drinking liquids that contain electrolytes are ways to lower the risk for low blood sodium.
