Swallowing function will gradually deteriorate with age, especially if the elderly have stroke, cognitive impairment and other diseases, plus missing teeth and other phenomena, which will make swallowing more difficult. Older people who choke easily when drinking water, or who cannot chew food easily, or who have recurrent pneumonia, are likely to have swallowing disorders. The elderly have a weak coughing ability and cannot easily expel foreign bodies by coughing. After swallowing disorder occurs, although they can barely eat, a small amount of residue or nasal and oral secretions may still enter the trachea, thus causing lung infection, which is known as aspiration pneumonia; in severe cases, food clumps may accidentally enter the airway and cause asphyxia or even death. Therefore, the elderly in the meal, must reduce the interference of the surrounding environment, attention, do not speak when the food or liquid in the mouth, if coughing phlegm, before eating should try to drain the phlegm before eating; maintain the correct eating posture, try to use the vertical sitting position, jaw slightly inward; food selection to uniform density, viscosity appropriate, not easy to loose, through the pharynx and esophagus easy to deform the food, such as paste food If an elderly person chokes on water, add some thickening agent to the water, and try to use a cup with a narrow bottom and wide mouth; when eating, take smaller bites, chew more slowly, and drink liquid food slowly; swallow each mouthful of food twice to make sure the food in the mouth is swallowed clean before eating the next bite; maintain a vertical sitting position for 30 minutes after a meal, and pat the back appropriately. Swallowing training is an important part of dysphagia treatment. For seniors with dysphagia caused purely by degeneration, we suggest the following adjustments that can be made to help seniors swallow food more safely Adjust breathing, try to use abdominal breathing and perform daily swallowing gymnastics training. Adjust swallowing style: change the flow of food through different postures. Swallowing with the head down can protect the tracheal passage and prevent food or liquid from flowing into the throat too quickly, making eating safer. For people who are bedridden for a long time, they need to shake the head of the bed at least 30 degrees and tilt the head forward 15 degrees before eating. Adjust the speed and volume of eating: swallowing in small bites can reduce the amount of food left in the throat. Swallow several times per bite and clear your throat after swallowing to ensure a clean swallow and avoid food or medication residue. If it is easy to choke with a straw, switch to a spoon or slanted cup to control the amount of food eaten. Adjust the texture of food: increase the consistency of liquids by adding thickening agents or thickening water or soup to make it thicker and reduce the flow rate of liquids to avoid flowing into the respiratory tract too quickly. Do not eat foods that are too hard to avoid getting stuck in the throat.
