The following complications are common in patients who are bedridden for a long time: 1. Lung infection. Patients who are bedridden for a long time will experience a decrease in resistance due to long-term inactivity, and the gas and phlegm in the lungs cannot be easily expelled, which may form inflammation when they accumulate in the lungs for a long time. 2. The production of stones. Patients who are bedridden for a long time consume things that are not easily digested, which can easily form urinary tract infections and stones. Families should encourage patients who are bedridden to drink more water and change their position frequently to prevent the formation of stones. 3. Bed sores. If the patient is bedridden for a long time and does not pay attention to hygiene, bed sores may occur.
