Understanding mmHg in Compression Socks

Let’s delve into the details of mmHg and how it plays a pivotal role in medical hosiery.

The Meaning of mmHg in Medical Hosiery

The term ‘mmHg’ stands for millimeters of mercury, a measure of pressure. In the context of compression socks, mmHg points to the degree of pressure or tightness the sock applies to your leg.
Think of it in terms of atmospheric pressure. Just like mercury barometers measure atmospheric pressure, the mmHg indicates the pressure on your legs exerted by compression socks. The higher the mmHg number, the tighter the sock.

How Compression Levels are Classified

Compression levels, measured in mmHg, are classified into four main categories, ranging from mild to extra firm. Observing these categories eliminates guesswork and ensures you select compression socks that offer precise pressure levels for your needs.

  • Mild Compression (8-15 mmHg): This level offers light pressure to alleviate leg fatigue resulting from minimal physical ailments or extended periods of standing. Ideal for routine wear and travel, these socks improve blood circulation, counteracting swelling in the ankles and feet.
  • Moderate Compression (15-20 mmHg): Deemed perfect for everyday wear, moderate compression socks act as a remedy for minor to moderate ankle and leg swelling, varicose veins, and during pregnancy.
  • Firm Compression (20-30 mmHg): These socks target medical issues like moderate to severe varicose veins, post-surgical recovery, edema, and lymphatic edema.
  • Extra Firm Compression (30-40 mmHg): The most intense level, these socks are primarily recommended for individuals with serious medical conditions such as severe lymphedema, venous ulcers, and deep vein thrombosis.

Remember, the appropriate compression level depends on your specific condition or reason for wearing the socks. Consulting your healthcare provider ensures you make an informed decision tailored to your individual needs.

Assessing Your Needs for Compression Socks

In order to select the best pair of compression socks for your needs, consider your lifestyle and any symptoms or medical conditions you may have. These elements hold the key to determining the specific mmHg rating necessary for optimal benefits.
