Even with modern pain management, some terminal conditions involve suffering, physical or psychological, that palliative care doesn't fully resolve, which advocates argue is central to the case for this option. Even the best palliative care can leave some patients with symptoms like severe nausea, breathing difficulty, or loss of dignity and autonomy that medication alone doesn't fully resolve. Advocates argue these cases, while a minority, deserve a legal option beyond continued suffering. Advocates argue that dismissing this minority of cases ignores real, documented suffering that current care can't always resolve.
