In "Macbeth," why does the doctor tell the Gentlewoman who attends Lady Macbeth to "remove from her the means of all annoyance"?

At this point in the play, Lady Macbeth has lost her sanity. The doctor wants her to rest and may also be concerned that she is suicidal. "To remove all means of annoyance" means to take away anything that would cause her to be disturbed or stressed. It also implies that the gentlewoman should take away anything that she can use to do harm to herself
