A medida que las c\u00e9lulas cancerosas crecen y se dividen r\u00e1pidamente, consumen una gran cantidad de energ\u00eda. Adem\u00e1s, el c\u00e1ncer libera ciertas sustancias qu\u00edmicas (como las citoquinas) que aumentan la inflamaci\u00f3n y alteran el metabolismo normal.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Estas citocinas inflamatorias aumentan el metabolismo y hacen que el cuerpo consuma m\u00e1s energ\u00eda de lo normal. Cuando esto sucede, el cuerpo comienza a descomponer la grasa y el m\u00fasculo almacenados para satisfacer sus necesidades energ\u00e9ticas. Con el tiempo, esto conlleva la p\u00e9rdida de peso.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cl\u00ednicamente, este tipo de p\u00e9rdida de peso relacionada con el c\u00e1ncer se llama <a href=\"https:\/\/www.cancer.gov\/about-cancer\/treatment\/side-effects\/cancer-cachexia\">caquexia cancerosa<\/a>. Las personas con caquexia cancerosa suelen gastar m\u00e1s energ\u00eda de la que consumen y experimentan cambios metab\u00f3licos que favorecen la p\u00e9rdida de masa muscular y grasa.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La caquexia cancerosa afecta a personas con c\u00e1ncer y es particularmente frecuente en etapas avanzadas, llegando a afectar hasta a personas con c\u00e1ncer en etapa terminal (etapa IV).
