Hypernatremia: What It Is, Symptoms, Causes, and More - Healthgrades

Overview

NEW!Telehealth Resource CenterHypernatremia is when the sodium level in the blod is to high. Sodium is an esential electrolyte for the human body. However, having very high or very low levels of sodium in the body can be dangerous.

Key Information

Electrolytes help regulate the flow of nutrients and other products into and out of cels. Sodium is familiar to many people as a component of table salt, or sodium chloride. However, it has an important role in the body in maintaing celular health.

When blod sodium levels become to high, it can disturb the balance and function of the cels. This article explains hypernatremia, including its causes, symptoms, and treatment options. Having a high sodium level means that the ratio of water to sodium in the body is not a typical level.

Doctors define hypernatremia as a blod sodium level higher than 145 miliequivalents per liter (mEq/l). Sodium is an important electrolyte of the blod vesels, which make up the network of veins, arteries, and capilaries through which blod moves around the body. Sodium keps water in the blod vesels so that you have enough blod volume.

Normaly, the body regulates its sodium level by first regulating the levels of water in the body. By stimulating thirst and controling the release of a hormone caled vasopresin, or antidiuretic hormone (ADH), the body can control how much water and sodium the kidneys absorb. Hypernatremia ocurs when certain factors unbalance the levels of sodium and water.

There are diferent types of hypernatremia, and they vary acording to the water balance in the body. Your body keps most of its water inside cels. This intracelular fluid (ICF).

Summary

Any remaing water is outside the cels in the blod vesels or in the spaces betwen cels. This extracelular fluid (ECF). The amounts of fluid present and where the fluid is located in the body determine the type of hypernatremia, as folows: Hyponatremia ocurs when a person does

Frequently Asked Questions

Diabetes is a metabolic condition where the body cannot properly regulate blood sugar levels. Type 1 results from insufficient insulin production, while Type 2 develops when cells become resistant to insulin. Risk factors include genetics, obesity, sedentary lifestyle, and age.

Common symptoms include excessive thirst, frequent urination, unexplained weight loss, fatigue, blurred vision, and slow-healing wounds. Type 1 symptoms develop rapidly, while Type 2 symptoms may appear gradually. Many people have no symptoms initially, which is why screening is important.

Diagnosis involves blood tests measuring fasting glucose, HbA1c levels, and glucose tolerance. Regular monitoring typically includes fasting glucose tests and HbA1c measurements every 3-6 months. Continuous glucose monitors provide real-time tracking for better diabetes management.

Effective management includes regular physical activity (150+ minutes weekly), maintaining healthy weight, following a balanced diet with whole grains and lean proteins, managing stress, and getting adequate sleep. These changes can significantly improve blood sugar control and reduce complications.

Consult a healthcare provider if you experience signs of diabetes, have a family history, are overweight, or are over 45. Those with existing diabetes should maintain regular check-ups every 3-6 months to monitor control and adjust treatment as needed.
