What is a seaweed abortion?

Laminaria, a type of seaweed, is a common tool used in certain types of abortions to help prepare the cervix for the procedure.


When inserted into the cervix, the laminaria absorbs moisture and begins to expand. This gradual expansion helps to open the cervix, making it easier to perform a surgical abortion or to insert an abortion-inducing medication, such as mifepristone, into the uterus.

One of the main advantages of using laminaria is that it allows for a more gradual dilation of the cervix, which can be less uncomfortable for the patient and may reduce the risk of complications. It also allows for more time for the patient to prepare for the abortion procedure and for the provider to ensure that the patient is fully informed about the procedure.

Laminaria is also sometimes used in second-trimester abortions, specifically dilation and evacuation (D&E) procedures. D&E procedures are more complex than first-trimester abortions and require a wider opening of the cervix, which can be achieved by using laminaria before the procedure.

It's important to note that laminaria is not the only option for cervical dilation. Other methods include using medication or mechanical dilators. The choice of method depends on the abortion provider's preference, the stage of pregnancy and the patient's health status.

Overall, laminaria is a safe and effective tool that can make the abortion procedure more comfortable for the patient and reduce the risk of complications. However, it is important to have an open and honest conversation with your healthcare provider about all the options available, and to make the best decision for your individual needs and circumstances.
