We know that malnutrition is resulting from a poor diet or a lack of food. It is happening when the intake of nutrients or energy is too high or too low or poorly balanced. The under-nutrition can lead to delayed growth or wasting while a diet which has too much food but it is not well balanced can lead to obesity. The malnutrition is involving a dietary deficiency. The poor diet can lead to a lack of vitamins, minerals and other essential nutrients.
The signs and symptoms of malnutrition in elderly include reduced sex drive and problems with fertility; depression; higher risk of complications after surgery; longer healing time for wounds; higher risk of getting sick and taking longer to heal; loss of fat, muscle mass and body tissue; always feeling cold; inability to concentrate; tiredness and ability; lack of appetite or interest in food or drink. In more severe cases, symptoms of malnutrition can include hair becomes dry and sparse, falling out easily; the cheeks appear hollow and the eyes sunken, as fat disappears from the face; skin may become thin, dry, inelastic, pale and cold; breathing becomes difficult.
There can be many different causes for malnutrition in elderly, such as depression and dementia; lack of interest in cooking; trouble chewing due to sore gums or poor dental health; living alone and eating for one; lack of mobility – unable to get to the store; changing taste buds; restricted diets, such as low sodium or low fat diets; limited income to buy nutritious food; trouble swallowing.
