How many years can a person live if his stomach is completely removed?

The number of years a person can live after total gastrectomy should be related to the patient's primary disease. If total gastrectomy is performed for benign lesions, it will not affect the normal life span of the patient under normal circumstances. If total gastrectomy is performed for malignant lesions, the impact on the patient's life is different due to different degrees of malignancy of the lesion. Some patients may only survive for 1 to 2 years, while some patients can survive for more than 10 years. After total gastrectomy, it will affect the digestion and absorption of food. Patients should eat soft and digestible food, reasonably match food, ensure adequate intake of nutrients, and eat a small amount of meals, not smoke or drink, etc., and pay attention to it.
