mmHg Explained: Find Your Ideal Support Level for Hernia and Stoma Management

Choosing the Right Level of Support Garment Using mmHg

CUI International Limited is part of the Medalin Group of Companies which has many years’ experience producing compression hosiery products for the NHS. All our compression hosiery is measured in mmHg (millimetres of mercury). At CUI, Our Hernia and Stoma support garments have always been designed to precise levels of compression. Using the expertise we have garnered from the manufacture of compression hosiery and in order to help you choose the right support garment, we are now including the compression level in mmHg alongside the support level for each garment.

Why mmHg?

Compression garments are measured in mmHg because this unit quantifies pressure, which is exactly what these garments are designed to apply to the body. mmHg is the recognised international medical standard for pressure and is the same unit used to measure blood pressure, making it a familiar and standardised way to describe how much pressure a garment exerts on the body. This is especially important for support garments where precise pressure levels are critical.

Why it Matters to You

For those living with a stoma or managing a hernia, the right support garment can make all the difference. Our commitment to measuring compression in mmHg means you can choose a garment that provides the optimum level of support and comfort you need. This helps to secure your appliance, reduce the risk of a hernia, and offer a feeling of confidence and security throughout your day.

This commitment extends to our Level 4 Bespoke Support, which is available for those with complex or advanced needs.

Frequently Asked Questions About CUI Wear Compression Levels

What level of compression is CUI Wear Level 1 Light Support?

Our Level 1 Light Support provides 4–6 mmHg of gentle compression. This is ideal for post-surgery comfort, all-day reassurance, and can even be worn while sleeping to give gentle support.

What are CUI Wear Level 2 Moderate Support garments used for, and is this recommended for hernia prevention?

Level 2 Moderate Support provides 6–14 mmHg of compression. This is highly recommended for everyday wear, light activities, and is the key level for hernia prevention in stoma patients, including those with an ileostomy, colostomy, or urostomy.

When should I choose CUI Wear Level 3 Firm Support?

Choose Level 3 Firm Support (up to 14–24 mmHg) if you have an existing hernia that requires strong support, or if you engage in strenuous activities, heavy lifting, or a manual job role. This stronger level of compression helps manage and contain the hernia during activity.

Do you offer Bespoke compression garments for complex stoma or hernia cases?

Yes, our Level 4 Bespoke Support provides 24–40 mmHg of highly customised compression. This service is specifically designed for complex or advanced medical requirements. Please contact our team for a consultation to discuss your specific needs.

What level of support is recommended following stoma surgery (ileostomy, colostomy, urostomy)?

Immediately post-surgery, Level 1 (4–6 mmHg) is recommended for comfort and gentle support. After the initial healing phase and consulting with your nurse, most patients transition to Level 2 (6–14 mmHg) for long-term support and hernia prevention.

How do I choose the compression level between a CUI Wear Girdle and an Adjustable Stoma Belt?

CUI Wear Girdles (and support tops) are classified by Levels 1–4, providing an exact, consistent compression (4–40 mmHg). Our Adjustable Belts offer flexible, targeted support. The level of compression applied by a belt is determined by how tightly you secure it, allowing you to customise the pressure where you need it most.
