Decubitus ulcers are mostly seen in patients with paralyzed lower extremities who are bedridden for long periods of time. Foods high in protein, vitamins and easy to digest are generally recommended, as vitamins and proteins keep the skin and mucous membranes healthy and also repair epidermal tissue. High protein foods such as eggs, milk, fish, etc.; high vitamin foods are most typically fresh vegetables and fruits, such as bananas, apples, cabbage, celery, etc. Since the patient himself is restricted in his activities, he will not consume much energy and his digestive ability is weak. It is recommended to avoid eating cold, stimulating, greasy and indigestible foods, and not to overeat, drink, or eat partially, so as not to increase the burden on the stomach and intestines. In addition to diet, patients with decubitus ulcers should also strengthen their daily care, keep local skin clean and dry, turn over regularly, and change positions every 2 hours for those who are bedridden for a long time to avoid long-term pressure on local skin. Some patients are prone to depression, pessimism and other negative emotions due to long-term bed rest and restricted activities.
