These terms are often used interchangeably, but in medicine they have different meanings.
If you’ve ever had surgery or even a minor cut, you may have heard both terms. A clinician might say you need stitches, and a surgeon might mention sutures. To most of us, they sound like two ways of saying the same thing. Let’s break it down.
What Is a Suture?
A suture is the material used to close tissue.
Think of it as the thread. Surgeons use sutures to hold skin, muscle, or internal organs together while the body heals. Sutures come in many forms; some dissolve on their own over time, and others need to be removed once healing has begun.
They also vary in strength, thickness, and composition, depending on where they’re placed and the amount of support the tissue requires. Sutures are made from both natural materials and synthetics. Some are designed to remain in the body permanently, while others are varieties that gradually absorb.
Choosing the right suture is part of the surgical plan that depends on the type of surgery, the tissue involved, and how long support is needed.
What Is a Stitch?
A stitch is the action itself—the individual loop or pass of the suture through tissue. In other words, the suture is the thread and the stitch is how that thread is placed.
So when someone says they “got stitches,” what they usually mean is that sutures were used and multiple stitches were made to close a wound. It’s a small distinction, but an important one in the scheme of things.
A Practical Case for Semantics
Understanding the difference can help us better understand and follow post-procedure instructions. For example, you might be told things like “Your sutures will dissolve on their own” or “Your stitches need to be removed in 7-10 days.”
Those directions depend on the type of suture material used and the placement of the stitches. And while closing a wound may look simple from the outside, suturing is a precise skill that takes years to master. Surgeons consider tension, blood supply, tissue type, and cosmetic outcome with every stitch. The goal isn’t just closure, but the most effective means for healing.
Whether it’s a few stitches after a minor procedure or complex suturing deep inside the body during major surgery, these tiny threads hold tissues together, protect healing structures, help prevent infection, and give your body the support it needs to repair itself.
So the next time you hear both terms, you’ll know they’re connected, but not quite the same.
