Understanding panic attacks
In nephrology practice, moments of acute physiological instability are familiar terrain. A sudden drop in blood pressure, a shift in electrolytes, an unexpected arrhythmia—these are events we are trained to anticipate and manage with precision. Yet there is another kind of acute episode that unfolds just as rapidly, often in the dialysis chair or clinic room, and can feel equally overwhelming to the person experiencing it: the panic attack.
For patients living with chronic kidney disease, the body is already a site of vigilance. Sensations are monitored closely—fluid shifts, fatigue, breathlessness, palpitations. This heightened bodily awareness, while adaptive in some contexts, can also create fertile ground for anxiety to escalate. A minor fluctuation in heart rate or a moment of dizziness during dialysis can be misinterpreted as catastrophic, setting off a cascade that culminates in panic.
A panic attack is not simply “anxiety.” It is a full-bodied experience: rapid heartbeat, chest tightness, shortness of breath, sweating, trembling, dizziness, and often a powerful sense that something is going terribly wrong, a sense of doom. Patients may fear they are dying, suffocating, or losing control. Importantly, these experiences are real at the level of physiology, even if they are not indicative of immediate medical danger.
In the clinical setting, the task is not only to reassure but to help patients develop a different relationship with these episodes—one that restores a sense of agency without dismissing the intensity of what they feel.
A useful starting point is helping patients recognize what is happening. Naming the experience as a panic response can itself be stabilizing. Without this recognition, the mind searches for explanations, often landing on the most threatening possibilities. In patients with kidney disease, this can easily default to fears of cardiac events or treatment complications. Gentle psychoeducation—explaining how the autonomic nervous system can produce these symptoms—can interrupt this spiral. The goal is not to convince patients that “nothing is wrong,” but to widen the interpretive frame: something is happening, but it may not mean what it initially seems to mean.
Once recognized, the next step involves working with the body rather than against it. Panic often brings a sense of urgency—the impulse to escape, to fight the sensations, or to call for immediate intervention. Paradoxically, this resistance can amplify the physiological arousal. Guiding patients toward slower, more deliberate breathing can be particularly helpful. Lengthening the exhalation, even slightly, engages parasympathetic pathways that counterbalance the surge of adrenaline. In the dialysis setting, where patients are physically constrained, this internal shift becomes especially valuable: it offers a form of movement without leaving the chair.
Equally important is anchoring attention. During panic, awareness narrows and becomes fixated on internal sensations. Encouraging patients to gently redirect their focus outward—to the rhythm of the dialysis machine, the feeling of their feet on the floor, or even the ambient sounds in the room—can help broaden this constricted field. This is not a form of avoidance, but of recalibration. It reminds the nervous system that the environment, in the present moment, is not inherently dangerous.
There is also a cognitive dimension to this work. Panic thrives on catastrophic interpretation: “This will get worse,” “Something terrible is happening,” “I will die.” These thoughts often arise automatically and feel convincing. Rather than attempting to suppress them, patients can be supported in noticing them as mental events rather than facts. A subtle shift—from “I am in danger” to “I am having the thought that I am in danger”—can create a small but meaningful distance. In that space, the intensity of the experience may begin to lessen.
Over time, as patients practice these responses, a different pattern can emerge. The panic attack, once an overwhelming and mysterious event, becomes more familiar and, crucially, more tolerable. The fear of the fear itself begins to diminish. This is particularly significant in chronic illness, where unpredictability is already a central burden. Reducing one domain of uncertainty can have ripple effects on overall psychological well-being.
For clinicians, there is also an important relational aspect. How we respond in these moments matters. Recognizing and managing our own aroused anxieties is paramount. Rapid escalation to medical interventions, while sometimes necessary, can inadvertently reinforce the patient’s belief that the episode is dangerous. Conversely, a calm, attuned presence—acknowledging the distress while conveying confidence in the patient’s capacity to endure it—can be profoundly regulating. The ability to contain our anxieties will lead to not just better support for the patients’ own, but will enhance their ability to do this for themselves.
It is worth noting that panic does not arise in a vacuum. In patients with kidney disease, it may be linked to broader themes: loss of control, dependence on treatment, fear of deterioration, or prior traumatic medical experiences. Addressing panic, therefore, is not only about managing acute episodes but also about engaging with these underlying narratives. Psychodynamic and supportive therapies can help patients articulate and metabolize these concerns, reducing the likelihood that they will surface somatically in moments of stress.
Ultimately, integrating panic management into nephrology care reflects a broader shift: recognizing that physiological and psychological processes are not separate domains but deeply intertwined systems. Just as we titrate ultrafiltration rates or adjust medications, we can also help patients modulate their internal responses to distress.
In doing so, we offer more than symptom control. We offer patients a way to remain present in their bodies—even when those bodies feel unpredictable—without being overtaken by fear.
