Dr. Patricia Mamani Flores

Dr. Patricia Mamani Flores is a distinguished internist and one of Bolivia's leading specialists in High Altitude Medicine, practicing at Hospital Obrero in La Paz. Situated at 3,640 meters above sea level — among the highest major cities on Earth — La Paz presents a uniquely demanding medical environment in which virtually every organ system is influenced by chronic hypobaric hypoxia. Dr. Mamani Flores has devoted her career to understanding, teaching, and treating the full spectrum of altitude-related medical conditions, from acute mountain sickness in visitors to the complex chronic syndromes that affect long-term Andean residents.

Hospital Obrero, operated by the Bolivian Social Insurance (Caja Nacional de Salud), serves a large population of workers and insured citizens across La Paz and the surrounding department. Within this institution, Dr. Mamani Flores practices broad Internal Medicine while maintaining a specialized clinic for altitude-related disorders — providing a service that is deeply valued by both local patients and the growing number of international trekkers, mountaineers, and researchers who pass through La Paz en route to higher destinations such as the Bolivian Altiplano and Sajama volcano.

Born and raised in the Bolivian highlands, Dr. Mamani Flores brings both scientific training and lived cultural understanding to her work. She speaks Aymara and Quechua in addition to Spanish and English, enabling her to communicate directly and sensitively with indigenous community members who may present with altitude-related illness after migration to or from highland areas. This linguistic and cultural competence is an essential dimension of her practice in a region where indigenous populations remain underserved by specialist medicine.

Dr. Mamani Flores is a nationally recognized advocate for altitude medicine education and has contributed to training programs for emergency and rural health workers in Bolivia on the recognition and initial management of altitude emergencies.

Dr. Mamani Flores completed her MD at a Bolivian university with a longstanding tradition in highland medicine, before undertaking an Internal Medicine residency at Hospital Obrero in La Paz — an environment that immersed her from the outset in the physiological complexities of altitude practice. Recognizing the unmet need for specialist altitude medicine expertise in Bolivia, she pursued additional training in High Altitude Medicine, including coursework through the International Society for Mountain Medicine (ISMM) and collaborations with altitude physiology research groups in Peru and Chile.

She obtained certification in High Altitude Medicine and has developed advanced skills in interpreting altitude-modified laboratory values (including hematocrit, arterial oxygen saturation, and red blood cell mass), managing hypoxia-driven polycythemia, and applying standardized protocols for acute altitude illness — including the Lake Louise criteria and the Lake Louise Score update — in both clinical and field settings.

Dr. Mamani Flores regularly participates in mountain medicine symposia and has completed wilderness medicine and pre-hospital altitude emergency training, reflecting the importance of field-level triage in Bolivia's geographical context where patients may need management hours before reaching a tertiary facility.

Dr. Mamani Flores's clinical expertise is built around two complementary pillars: general Internal Medicine and specialized High Altitude Medicine. In her general internal medicine practice, she manages hypertension, diabetes, respiratory disease, infectious conditions, and complex multi-system presentations in patients whose underlying physiology is shaped by altitude exposure. She is expert at interpreting laboratory results in the context of altitude-adapted normal ranges, avoiding misdiagnosis that can arise when sea-level reference values are uncritically applied to highlanders.

In altitude medicine, she manages the full spectrum of altitude-related illness. For acute presentations — AMS, HACE, and HAPE — she applies rapid assessment tools, supplemental oxygen therapy, descent protocols, and pharmacological management with acetazolamide, dexamethasone, and nifedipine. For chronic conditions, particularly Monge disease (chronic mountain sickness), she designs individualized management plans that may include therapeutic phlebotomy to reduce pathological polycythemia, phosphodiesterase-5 inhibitors for associated pulmonary hypertension, and in refractory cases, coordinated descent to lower altitudes.

She also advises visiting mountaineers and trekkers on acclimatization strategies, pre-travel medication protocols, and risk stratification for ascent to Bolivia's high-altitude destinations, and provides post-altitude evaluation for individuals experiencing delayed symptom resolution.

Dr. Mamani Flores is a productive contributor to altitude medicine research, with particular interest in the epidemiology of chronic mountain sickness in Bolivian mining and highland agricultural communities, where the condition imposes substantial disability and reduced life expectancy. She has collaborated with research teams in Peru and Chile — countries with overlapping Andean altitude medicine challenges — on studies examining hematological thresholds, cognitive impairment in excessive erythrocytosis, and the cardiovascular burden of altitude polycythemia.

Her research on the management of HAPE at very high altitude (above 4,000m), including the practical limitations of rapid descent in remote Bolivian terrain, has contributed to national-level emergency protocol development. She has also published clinical observations on altitude physiology adaptation differences between indigenous Aymara people with generations of highland ancestry and more recently migrated lowland populations — a distinction with significant clinical management implications.

Dr. Mamani Flores is one of the most sought-after medical consultants in La Paz for international visitors experiencing altitude-related symptoms. Mountaineers, trekkers, researchers, and travelers who become unwell at altitude frequently seek her expertise, and she provides both acute clinical management and structured acclimatization counseling. She consults in Spanish and English, and her multilingual capacity in Aymara and Quechua further broadens her accessibility.

For international patients requiring complex altitude medicine evaluation — including assessment for altitude fitness prior to planned high-altitude expeditions or work assignments — Dr. Mamani Flores offers comprehensive pre-travel consultations at Hospital Obrero. Video consultations are available for follow-up after acute altitude illness events or for remote pre-travel advice for patients planning visits to Bolivia's highland regions.

Dr. Mamani Flores is a member of the International Society for Mountain Medicine (ISMM), the Sociedad Boliviana de Medicina Interna, and the Sociedad Latinoamericana de Medicina de Montaña. She has been recognized by Hospital Obrero for her contributions to internal medicine education and for establishing the institution's altitude medicine consultation service. She has received acknowledgment from the Bolivian Ministry of Health for her work in training rural health workers in the recognition and management of altitude emergencies. She is regularly invited to present at altitude medicine symposia in Bolivia, Peru, and Chile.
