Hypernatremia is when there is too much sodium in the body. It may be serious and requires care from your doctor.
Hypernatremia happens when there is an imbalance in the amount of water and sodium in the body—too little water, too much sodium.
The main cause of hypernatremia is having more water leave your body than enter it. This causes dehydration. A person can become dehydrated in different ways, such as:
- Drinking too little fluids
- Excessive sweating
