The Hidden Danger of Over-hydration

Over-hydrationMost people realize the serious dangers that come with dehydration, but few understand the risks associated with drinking too much water. To protect yourself and your children, learn the little-known dangers of over-hydration.
An important electrolyte that’s key to human survival, sodium helps regulate the amount of water inside and around cells. When you consume too much water, you can dilute the amount of sodium in your body, resulting in a condition known as hyponatremia. When this occurs, your body’s water levels may rise, causing swelling in and within the body. This swelling can cause mild or life-threatening health problems, including swelling of the brain, coma or death.
Hyponatremia symptoms can include:
• Confusion
• Headache
• Seizures
• Serious fatigue
• Nausea and vomiting
• Irritability or restlessness
• Muscle spasms, weakness, or cramps
• Coma
How Much Water is Too Much?
Contrary to popular opinions, there are no formal guidelines for how much water a person should drink every day. A number of factors can influence an individual’s water needs, including body weight, diet, activity level, and weather. According to the Institute of Medicine, “adequate” water intake spans from three cups per day for infants to 16 cups for lactating women.
Typical signs of adequate hydration include pale or straw-colored urine, along with active sweating when appropriate. If you are well-hydrated, your skin should rebound right away after being pinched. Your skin should also take no more than two seconds to return to its normal color after blanching via pressure.
When to See a Doctor
Obviously, you should drink plenty of water when you are thirsty; however, if you notice that you are excessively thirsty for no apparent reason, visit your doctor, since this could be a sign of a serious underlying condition.
You should also see your doctor if you have a medical condition that increases your risk of hyponatremia, or if you show symptoms after participating in high-intensity activities, which increase the risk of hyponatremia. You can also reduce your risk of hyponatremia during strenuous activity by consuming sports drinks instead of – or in addition to – water.

"The overall care I received was excellent! I also appreciate your affiliation with Yale New Haven Hospital."

Derby, CT

"Throughout the visit I felt like the staff really cared. The Doctor took his time talking with me about my symptoms, and I felt like he listened to all my concerns and took that into consideration when recommending the right treatment. Thank you!"

Hamden, CT

"I had to take my son in for an ear infection following a sudden change in temperament at daycare. He was inconsolable the entire car ride but when we got there and by the time we left this care facility he was back to his normal happy go lucky little two year old boy. I highly recommend PhysicianOne Urgent Care."

Westwood, MA

"I wanted to take a moment to thank you for the attention you gave me last week. My son was started on antibiotics and ear drops. Within 24 hours he began to feel better. The poor kid had been going to school in tears because he was afraid of missing any more days, but feeling (and looking) just awful! He's not been able to even think about lacrosse practice, but thanks to starting him on antibiotics, he was thrilled to return to practice today."
