Studies indicate that COPD patients often experience reduced appetite and limited dietary diversity due to these taste changes. Pulmonary rehabilitation has emerged as a potential solution, as it has shown promising results in enhancing taste sensitivity for salty, sweet, and bitter tastes. The use of High-Flow Nasal Cannula (HFNC) treatment and long-term oxygen therapy in COPD patients may also play a role in influencing taste and smell perception, with HFNC possibly leading to improvements. However, the impact of smoking on taste perception remains variable. Altered taste perception may lead to reduced appetite, resulting in inadequate nutrient intake and aversions to specific food groups, further compromising dietary quality. While zinc supplementation has been effective in addressing taste and smell dysfunctions, there is a lack of specific evidence regarding its use for COPD patients with taste and smell impairments. Although pulmonary rehabilitation shows promise in improving taste sensitivity, more research is required to explore additional interventions for COPD patients&#39; taste perception alterations. Addressing these taste changes and their effects on dietary intake is crucial to enhance the nutritional status and overall health of COPD patients, particularly among older individuals with the condition.</span></span></span></span><br> &nbsp; Chronic Obstructive, Pulmonary Disease, Taste perception. 96 103 http://intjmi.com/browse.php?a_code=A-10-1-557&slc_lang=fa&sid=1 Nazanin Zahra Valizadeh 10031947532846006298 0009-0006-2474-935X Yes Associate Professor of Emergency Medicine, Faculty of medicine, Mashhad University of Medical Sciences, Mashhad, Iran Elham Pishbeen 10031947532846006299 10031947532846006299 No Associate Professor of Emergency Medicine, Faculty of medicine, Mashhad University of Medical Sciences, Mashhad, Iran Mansour Deylami 10031947532846006300 10031947532846006300 No Assistant Professor of Anesthesiology, 5 Azar Hospital, Golestan University of Medical Sciences, Gorgan, Iran Ehsan Rahmanian Kooshkaki 10031947532846006301 10031947532846006301 No Department of Pediatrics, Jahrom University of Medical Sciences, Jahrom, Iran.
