Hi Pamela Mae,
How are you? Absorbable sutures are made from materials that can dissolve gradually inside the body, such as catgut. These sutures are ideal for repairing muscles, because muscles require strong sutures when they are first healing yet they heal quickly. The body absorbs them usually within about 60 days. Nonabsorbable sutures like nylon, on the other hand, are not absorbed by the body. This is also true to foreign objects such as plastic, small splinters and even bone spurs. I hope this helps.
Take care and best regards.
