The vast majority of patients, who spend their days in bed with reduced exercise, have their original rhythm of life disrupted and often have a decreased appetite and do not want to eat. Older patients, those with weaker constitution or poor mental capacity are more prone to this, and it is especially obvious in the short period after surgery. The diet should be nutritious, with good color, aroma and taste, which can stimulate the appetite. Eat more vitamin C-rich vegetables such as tomatoes, amaranth, bok choy, cabbage and radish as appropriate to promote bone scab growth and wound healing. According to the latest research, patients may need to supplement trace elements such as zinc, iron and manganese after surgery. Animal liver, seafood, soybeans, sunflower seeds and mushrooms contain more zinc; animal liver, eggs, beans, green leafy vegetables, wheat and bread contain more iron; cereals, mustard, egg yolk and cheese contain more manganese. In the early stage, there is often constipation, which is more common in bedridden patients; it is advisable to eat more vegetables containing more fiber, and eat some bananas, honey and other foods that promote defecation. If necessary, take laxative drugs, such as marijuana pills 6 grams to 9 grams, once or twice a day. Bedridden patients are prone to urinary tract infections and urinary tract stones, so it is appropriate to drink more water for diuresis. Postoperative patients do not need to “avoid”, there are no special restrictions on diet, but do not smoke. Smoking affects the wound healing ability and fracture healing.
