Maintaining Body Composition in HIV Disease

by Margaret Davis, Rd, CNSD

Have you had your body composition tested recently? Do you weigh yourself regularly? These are important factors in monitoring your overall progress the longer you have been living with HIV. Weighing yourself is an easy way to see if you are maintaining your weight in a range that is normal for you. Unfortunately, the scale only tells you what your total weight is and not what it is composed of - water, muscle, fat, bones and other structural tissues.

With HIV, we can see unusual pattrns of change in these body components - loss of muscle tissue, fat accumulation in the stomach or chest, and loss of fat in the face, arms, and/or legs. Loss of muscle mass is often the least obvious to the naked eye and can be the most serious if it is not corrected. Muscles, both internally and externally, are the metabolic engines that run most of the body's functions. Loss of muscle can affect how you digest and process your food, how efficiently your heart pumps, and how much general strength you have to move around.

Anyone who has been infected with HIV for a while has probably heard the term "wasting." YOu may have even known someone who got very thin and looked like they were starving even though it seemed like they were eating enough. THey were probably losingmuscle mass and could not function normally. This is more common among HIV+ men, but also happens in women. Losing as little as 5% of your normal weight can inrease your risk of health problems due to AIDS.

It is possible to detect and treat wasting early if you have your body composition tested regularly. Many health care workers use a simple method called bioelectrical impedance

Manteniendo la compasicion corporal

por Margaret Davis, RD, CNSD

¿Se ha hecho un análisis de composición corporal ultimanamente? ¿Se pesa rutinariamente? Estos son factores importantes para controlar el progreso de la enfermedad del VIH, sobre todo si hace mucho tiempo que es VIH positivo. Pesarse es una buena manera de saber si esta manteniendo su peso dentro de los parámetros normales. Lamentablemente, la balanza o la pesa solo le informa su peso total y no su composición de agua, músculo, grasa, hueso y otros tejidos estructurales.

En personas VIH positivas, suelen ocurrir una serie de cambios en los componentes del cuerpo: perdida de tejido muscular, acumulación de grasa en el estomago y en el pecho y perdida de grasa en la cara, brazos y piernas. La pérdida de músculo es el cambio menos obvio a simple vista y puede llegar a ser el mas serio si o se corrige. Los músculos, internos y externos son los motores metabólicos que hacen fucionar al cuerpo. La pérdida de musculo puede afectar la manera de digerir y procesar los alimentos, la manera en que el corazón bombea sangre y la energia que usted tien para moverse.

Aquellos que han estado infectados con el VIH desde hace un largo tiempo seguaramente han oido el término "desgaste progresivo" o "wasting". Es posible que haya concido a alguien que adegazó much y se veia como si pasara hambre a pesar de que comiera lo suficiente. Seguaramente esta persona estaba perdiendo musculo y su cuerpo no funcionaba normalmente. Estos es más común en hombres VIH+ pero tambien le ocurre a las mujeres. La péerdida de tan solo el 5% del peso corporal puede aumentar el riesgo de padecer problemas relacionados al SIDA.

Es posible detectar el desgaste progresivo si se hace un analisis de la composición corporal rutinariamente. Muchos proveedores de salud utilizan un método simple llamado análisis de impedacia bio electria (BIA en inglés). Los análisis BIA ayudan a determinar cuánto músculo, grasa, esqueleto, agua y otros tejidos forman el cuerpo. Estos resultados son comparados a los "normales" al igual que se hace con el peso corporal. Dependiendo de los
