How long a nasal feeding patient can live depends on the patient’s own age, underlying diseases and whether sufficient nutrients are given at the time of nasal feeding. For example, if the patient is about 60 years old, if there are no other serious underlying diseases, like heart disease, cerebral infarction, cerebral hemorrhage, lung cancer, etc., and normal nutrients are given by nasal feeding, the patient can basically live to an average life expectancy of 80-90 years. If the patient is given insufficient nutrition by nasal feeding, hypoproteinemia and electrolyte disorders will easily occur, which may lead to systemic edema and easy infection, and hypokalemia will also induce cardiac arrhythmia, which may lead to fatal heart disease, and this situation will seriously affect the life expectancy, and the patient may only last 1-2 months after nasal feeding before dying, so it is very important to give regular nutritional support.
