The cause of splenomegaly needs to be investigated and the diet adjusted according to the cause of the disease. If it is caused by physiological reasons, there is generally no need to pay attention to the diet; if it is caused by pathology, the diet should pay attention to not eating spicy and stimulating foods or hard and indigestible foods. 1. Spicy and stimulating food: splenomegaly is the main manifestation of splenic diseases and is a very important pathological sign. Extra attention should be paid to eating less or no spicy and stimulating foods, such as chili peppers, green onions, ginger, alcohol, coffee, strong tea, etc., so as not to stimulate the gastrointestinal tract and cause abdominal distension or vomiting. 2. Hard and indigestible food: Hard and indigestible food such as melon seeds, walnuts, crispy bones, hard steamed bread slices and other food have the risk of scratching the esophagus, which can easily cause gastrointestinal bleeding. If there are signs of splenomegaly, the cause needs to be identified in time. Diet should be well-structured, light and easy to digest, eat more fresh vegetables and fruits, and pay attention to protein supplementation.
