This article presents a personal viewpoint proposing the application of the Iceberg Theory to the medical history. In this way, the medical history becomes a "minimalist narrative" where the physician possesses a deep and comprehensive understanding of the patient (biography, genogram, context), but records only the key elements that, due to their weight and precision, suggest the full complexity of the case without overloading the document with irrelevant information. Applying the iceberg principle is vital because it transforms the medical history from a list of symptoms into a map of meanings. It avoids the "hole" of ignorance: It forces the physician to investigate the background (genogram, biography) so that what they write is substantiated. If you don't know the background, the diagnosis is superficial and the intervention fails. It allows recording only the essential (the tip) without losing the complexity of the patient. A good clinician "says a lot with a little." It reveals the root cause: By knowing the submerged mass (e.g., unresolved grief), you understand why the physical symptom (e.g., insomnia) persists. What is unseen underpinning what is seen. Treat the patient as a human being with a history, not as a generic clinical case. The "power" of the medical history comes from that emotional and social subtext. When the physician understands the underlying structure, they can propose treatments that the patient will actually adhere to, because they respect their biography and identity.

 “I always try to write on the principle of the iceberg. There is seven-eighths of it underwater for every part that shows. Anything you know you can eliminate and it only strengthens your iceberg. it is the part doesn't show. if the writer omits something because he does not know it, then is a hole in the story.” (Ernest Hemingway. American writer and journalist, one of the leading novelists and short story writers of the 20th century) (1)

Creating the medical record is the only mandatory writing exercise that physicians perform, both during their clinical rotations as students and throughout their professional practice. It involves recording the aspects they consider relevant from what the patient (or those around them) has told them—the part corresponding to the anamnesis—and includes data obtained from observation and examinations. This information is used for the analysis that leads to diagnosis, treatment, and subsequent follow-up.

If patient-centered medicine is to become a widespread reality in academic medical centers, and emphasize the relationship between the individual and the community and between individual health and public health, educational initiatives must include reforming the medical record. The medical record is part of the hidden or informal curriculum of medical school and residency, defining for students and residents the essential ingredients of competent medical care.

Whatever its merits, the conventional, problem-oriented medical record is a pathology-oriented record that helps perpetuate a disease-centered model of biomedical practice. Patient-centered medicine requires a patient-centered medical record, one that addresses the person and the patient's perspective with the same competence with which it addresses the patient's illness (2, 3).

The general practitioner (GP) shares their life with many other lives, some with laughter, some with tears. Almost all patients seem to find it rewarding, often even a relief, to have a doctor who wants to know more about them, beyond their symptoms. The stories—the way characters, real or imagined, live and recount the events of their lives—are always fascinating and intriguing: wanting to know more about what patients do, where they come from, and what kind of family they have. Almost everyone harbors a desire to be known and finds satisfaction in meeting someone who wants to know them.

Storytelling in medicine is crucial because it helps healthcare professionals better understand their patients, strengthen the doctor-patient relationship, and improve medical care. In addition, it fosters empathy, personal and professional reflection, and can help prevent burnout among physicians. Storytelling, biography, genogram and context are suitable for any medical specialty (4).

The medical record aims to record a single episode or a series of episodes in a person's life. However, little is known about how to effectively carry out this narrative exercise, both in form and substance, in general practice. A patient's story transcends the mere anecdote of symptoms, encompassing their life contexts, which are generally absent from a typical medical history. The anecdote, on the other hand, is merely a reference point upon which the physician typically focuses their inquiry. These are the circumstances in which a patient's medical history truly reflects the history of an illness (5).

In this context, we present a form of medical record in general medicine, based on the iceberg principle, which strengthens it and transforms it from a list of symptoms into a map of meanings.

This article, which is a personal viewpoint, aims to reflect on, conceptualize, and propose, based on a selected narrative review and the author's experience, a model of a meaningful medical history for the physician who constructs it, for other colleagues who consult it, and for the patient.

To create a medical record, we must apply Ernest Hemingway's Iceberg Principle (1): the GP must know all the details in order to later omit some. If details are omitted because they are unknown, the medical history fails; it is not useful as a tool to aid diagnosis and treatment.

The quote at the beginning of this text from Hemingway (1) perfectly summarizes the "Iceberg Theory" (or theory of omission), which posits that the subtext and emotional depth of a story (the submerged seven-eighths) are stronger when the writer omits details they deeply understand. Superficial details are eliminated to focus on the essential action, forcing the reader to become involved and feel what remains unsaid.

The idea is that the “dignity of an iceberg’s movement”—a metaphor also attributed to Ernest Hemingway that describes the elegance and confidence of a text (or action) where only 10% is shown (the surface), while the remaining 90% (the structure, the research, the hidden truth) firmly supports that visibility—is due to the fact that only one-eighth is above water. If a writer omits things they know well, the reader will feel the emotional force and the background of what is left unsaid. But if the author omits something simply because they don’t know it, the story feels empty or “holey.” That is, the omission must be a conscious decision, not a lack of research or knowledge.

The key aspects of the iceberg theory are:

1. Intentional omission: If a writer knows all the background information, they can omit details, thus reinforcing the nuances of the story.

2. The "hole" in the story: Omitting details out of ignorance, rather than artistic choice, creates a narrative gap that weakens the story.

3. Reader participation: By offering only the "tip" of the iceberg (the visible eighth), the reader is trusted to fill in the subtext, making the experience more immersive.

4. Subtext over explanation: Instead of describing the emotion, the writer shows it through action, dialogue, and silence. Hemingway argued that this method allows for a "dignity in movement," mimicking how real life works, where actions often speak louder and with more mystery than a straightforward explanation (6).

Applying Hemingway's Iceberg Theory to clinical practice (primarily to the biopsychosocial elements: Storytelling, Biography, Genogram and Context) transforms the medical history from a simple record of symptoms into a profound therapeutic tool. The key is that the general practitioner (GP) must be aware of the entire biopsychosocial background (the submerged part), but only record the essential elements that give meaning and weight to the diagnosis (the visible tip).

Thus, applying the Iceberg Theory to the biopsychosocial tools of the medical history would be:

1. The Genogram as the submerged structure: What is omitted but known. The genogram is not just a family tree; it is a map of the "eight-ninths" that are not visible at first glance. The physician uses the genogram to understand multigenerational transmission patterns, unresolved traumas, family alliances, or conflicts; this may be omitted when writing the medical history, but it is known. By understanding these dynamics (even if they are not exhaustively detailed in each progress note), the GP interprets the patient's current symptom with an emotional "seriousness" that would otherwise be ignored. If the physician ignores this background, there is a "gap" in their understanding of the case (7-9).

2. The Patient's Biography: The Weight of Subtext. Integrating short biographies allows the medical team to see the person behind the patient (4, 10). Sharing a brief biography establishes a stronger connection and improves care without needing to over-explain every detail of the subject's life. The biographical account should be honest and based on clear observation. What the patient chooses not to say, or what the physician chooses not to record but is aware of, gives the diagnosis a solid foundation and avoids dehumanization (5).

3. Medical Storytelling: Narrating from the "Tip." Storytelling in medicine seeks to connect symptoms with the patient's life context (11). Scientific studies have shown that storytelling affects hormone levels, trust, and behavior. It has also been demonstrated that storytelling increases oxytocin and decreases cortisol and pain perception in hospitalized pediatric patients. The neural responses to hearing a story are similar in most people regardless of race, origin, or cultural background (12).

A well-written medical history based on this theory should avoid unnecessary embellishments and focus on the facts that reveal the truth of the illness (TABLE 1). 

Table 1: Clinical Application of The Iceberg Medical Record

The "gap" must be avoided: If the GP omits a key social or emotional detail (such as recent bereavement or a work conflict) because they did not take the time to inquire about it, the medical history remains incomplete. But if they are aware of it and decide to summarize it in a powerful sentence that evokes its full weight, the medical narrative is strengthened (13).

The Iceberg Theory is applied by treating the medical history as a “minimalist narrative” where the physician possesses a deep and comprehensive understanding of the patient (biography, genogram, context), but records only the key elements that, due to their weight and precision, suggest the full complexity of the case without overloading the document with irrelevant information.

To apply this theory, we compare a conventional medical note (full of “gaps” due to a lack of context) with an Iceberg-style note (where brevity suggests depth). Let's imagine a scenario of a patient with chronic abdominal pain without a clear organic cause.

1. The Clinical Note with “Gaps” (Superficial): “45-year-old patient presents with recurrent epigastric pain of 3 months. It does not improve with antacids. Normal physical examination. Endoscopy requested to rule out ulcer. Plan: Omeprazole 20mg.” The flaw lies in the fact that the physician omits the context because they are unaware of it. There is no subtext, only an isolated symptom. It is an incomplete history.

2. The Clinical Note "Iceberg" (What is written vs. what is known). Here are some facts the doctor knows (The submerged base):

• Genogram: The patient lost his father to colon cancer 4 months ago (close bond, pathological grief).
• Biography: He is the breadwinner for a large family; he fears getting sick and having to stop working.
• Storytelling: The pain always appears on Sunday nights (anticipation of work on Monday).

What the doctor writes (The visible tip): "45-year-old patient with epigastric pain of 3 months' duration, coinciding with recent paternal bereavement and role overload as sole provider. The symptom presents a somatized anxiety component linked to the work environment. Unremarkable physical examination. Plan: Biopsychosocial approach; symptom diary and emotional follow-up initiated."

This second clinical note works because: It eliminates the irrelevant: It doesn't detail every conversation about the father, but it mentions "grief" and the "provider role"; There's a weighty suggestion: By mentioning grief, the medical reader understands that there's an immense emotional burden beneath that stomach ache; There are no "gaps": The doctor doesn't omit the real cause (stress/grief) out of ignorance, but rather synthesizes it so that the diagnosis has dignity and strength.

For a narrative genogram, the goal is not to draw a complete or perfect family tree, but to write two or three lines that reveal the entire "mass" of the family dynamics without having to describe it branch by branch. For example, this might appear in a clinical history as follows:

Clinical Case: Patient with chronic anxiety

The "Iceberg" (what is written): "Genogram: Third generation of paternal abandonment. Patient assumes the role of 'universal caregiver' in an enmeshed family constellation. Rigid alliance with a depressed mother."

What's "under the water" (what the doctor knows but summarizes): 1) Abandonment: The grandfather left, the father left, and the patient's current partner is absent. There is a pattern of repetition; 2) Universal caregiver: She has no life of her own; she pays her siblings' debts and takes care of her nephews and nieces; 3) Rigid alliance: She cannot make decisions without her mother's approval, which generates suffocating guilt.

The Iceberg Principle strengthens the medical history because: 1) It avoids the "hole": It doesn't say "family problems" (which says nothing). It says "rigid alliance," which is a precise technical term that carries the full weight of the relationship; and 2) It uses economy of words: Instead of a 5-page biography, you use concepts like "enmeshed constellation." Any colleague who reads that understands that the family lacks healthy boundaries.

The biography in a medical history is often a "black hole": either it doesn't exist (there are only identifying details like age and occupation) or it's a chaotic collection of anecdotes. Applying the Iceberg Theory, the biography should be an "impact biography": a few words that reveal the patient's identity and resilience. It doesn't write their life story, but rather the meaning of their life. For example. In a patient diagnosed with a chronic illness (Diabetes, hypertension, COPD, etc.): 1. The "gap" biography (The usual approach): "Retired patient, lives with his wife. Worked in construction. Enjoys walking." The problem is the lack of emotional depth. It doesn't explain why the patient is resisting treatment or what motivates him.

2. The "iceberg" biography (What the doctor writes): "Former construction foreman; identity forged through physical effort and autonomy. Currently grieving the loss of his role as provider. His garden is his last remaining space of competence and control."

What Lies "Under the Water" (What the doctor knows but summarizes):

1. Identity: The patient is not "a retiree," he is someone who was in charge and a builder. The illness makes him feel weak; 2. Resistance: If the medical treatment prevents him from working in his garden, he will not comply, because the garden is the only thing that remains of his former identity; 3. Conflict: His "stubbornness" is not a lack of intelligence, it is an attempt to not lose his dignity as a "strong man."

Rules for an "Iceberg" Biography: Identify the "Vital Verb": What defines this person? (To care? To create? To command? To explore?); Replace adjectives with facts: Instead of "resilient patient," write: "Survivor of economic crisis; prioritizes family stability over self-care"; The current conflict: Describe how the illness clashes with this biography.

An Iceberg-type medical history is different for several reasons. Table 2 presents an example: 1) With just four lines, any colleague reading the note understands that the headache is not solely due to stress, but rather to a specific life structure; 2) You eliminate the unnecessary details: The parents' entire life story isn't recounted, only their "supportive role"; 3) You strengthen the diagnosis: The note has "dignity of movement" because the weight of the patient's responsibility behind the symptom is palpable.

Table 2: "Iceberg style" medical record template. It is designed so that you gather a lot of information in the interview (the submerged base), but only record the keywords that support the case (the visible tip).

In short, applying the iceberg principle is vital because it transforms the medical history from a list of symptoms into a map of meanings (Figure 1).

It avoids the "hole" of ignorance: It compels the physician to investigate the background (genogram, biography) so that what they write is substantiated. If you don't know the background, the diagnosis is superficial and the intervention fails. It allows you to record only the essentials (the tip) without losing the patient's complexity. A good clinician "says a lot with a little." It reveals the root cause: By understanding the underlying structure (e.g., unresolved grief), you understand why the physical symptom (e.g., insomnia) persists. What is unseen sustaining what is seen. Narrative dignity: Treat the patient as a human being with a history, not as a generic clinical case. The "power" of the medical note comes from this emotional and social subtext. Therapeutic efficacy: When the physician understands the underlying structure, they can propose treatments that the patient will actually adhere to because they respect their life story and identity.
