Bioimpedance Spectroscopy: The Bioelectric Health Map in Tomorrow’s Medicine
The accelerated social changes of recent decades (urbanization, digitalization, transformation of dietary patterns, increased sedentary behavior, and chronic stress) have profoundly reconfigured the health profile of populations. Today, we face not only infectious or deficiency diseases, but a silent epidemic of non-communicable diseases (NCDs): obesity, type 2 diabetes, sarcopenia, osteoporosis, hidden malnutrition, and functional frailty1. […]
Menopause and body composition: contributions of bioimpedance
The physiological transition of menopause Menopause is a period in women’s lives characterized by a significant number of physiological changes, the main cause of which is the progressive decrease in hormone secretion by the ovaries, particularly estrogens¹. It generally lasts 4 to 5 years at a median age of 51 years²,³ and is characterized mainly […]
Phase Angle: A Marker to Monitor Athletes’ Fitness Status
Training Load and Physical Fitness The benefits of physical activity and chronic physical exercise on health are well known, with numerous musculoskeletal, cardiovascular, metabolic, and cerebral adaptations. Paradoxically, acute exercise induces significant physiological stress: increased acidity or mechanical constraints on the muscular and skeletal systems that are objectively detrimental to the body. However, it is […]
The Phase Angle: What Is It and Why Is It Becoming Necessary?
Definition of Phase Angle In bioelectrical impedance analysis (BIA), the phase angle is a raw bioelectrical parameter obtained in two ways: The calculation of this parameter suggests that the phase angle would not be associated with biological functions or structures; however, the interest in it in the scientific literature and its clinical use has strongly […]
Early detection of malnutrition in the elderly: a clinical proposal based on multifrequency bioimpedance
Introduction Aging represents a growing challenge in public health, including the early detection of malnutrition in older adults. This condition, frequently underdiagnosed, negatively impacts functionality, quality of life, and clinical prognosis. Traditional methods of nutritional assessment, focused on body mass index (BMI), medical history and anthropometry, are insufficient to identify metabolic and cellular alterations in […]
Pre- and Post-operative Management in Bariatric Surgery with Spectroscopic Bioimpedance: Why and How to Monitor What Really Matters?
Bariatric surgery doesn’t end when the patient leaves the operating room. Nor does it start at the moment of anesthesia. Its true beginning is weeks before, in metabolic preparation, and its long-term success is defined in the following months, with a follow-up that goes far beyond the weight on the scale. Today, as professionals who […]
