The Portuguese population is one of the oldest in Europe, therefore medical services, namely, primary health care, attend many people with multimorbidity and polypharmacy. Communication with these patients within medical consultation is an essential tool to achieve positive results. However, talking about food diets (just like reducing the use of salt and carbohydrates) and discuss the medication plans can be a difficult process. Although in the case of food, there is a layman’s knowledge about what is healthy food; regarding medicines, there is an appreciation of their administration as a guarantee of protection against the disease, and a sense of risk in their withdrawal (even when it is not needed or prejudicial). In any case, the concepts and words used in the physician’s dialogue with patients may have different meanings and values for clinicians and elderly patients. Physicians should be informed of the paradoxical feelings, ideas, and images that words and expressions such as dieting, not taking medication, being careful, and others, arouse in elderly patients who use a grammar of memories, experiences, and interpretations about health and disease shaped by culture, gender, and age. In this regard, language assumes itself as a central mediating element in the clinical relationship.
