Hip replacement surgery is a major orthopedic procedure that demands careful preparation and recovery planning. While most patients focus heavily on physiotherapy and medication, nutrition is often the most overlooked factor in the entire recovery journey. What you eat before and after surgery can directly influence wound healing, bone strength, infection risk, and how quickly you regain mobility. This guide outlines everything patients need to know about nutritional considerations surrounding hip replacement surgery.
Research consistently shows that patients who are nutritionally deficient before surgery experience higher rates of postoperative complications, including slower wound healing, increased infection risk, longer hospital stays, and reduced implant stability. On the other hand, patients who are well-nourished before and after surgery recover faster, regain strength sooner, and report better overall outcomes.
Hip replacement surgery in particular places high demands on bone health, soft tissue repair, and cardiovascular function during recovery. Nutrition directly supports all three of these areas, making dietary planning an essential part of the surgical process.
Albumin and pre-albumin levels indicate overall protein stores in the body. Low levels are associated with poor wound healing and higher surgical risk. Hemoglobin and iron levels determine whether the patient is anemic, which can affect how well the body tolerates blood loss during surgery. Vitamin D and calcium levels are especially important for bone health, since the implant needs to integrate successfully with existing bone tissue.
If deficiencies are identified in the weeks before surgery, your doctor may recommend targeted supplementation or dietary changes to optimize your levels before the procedure takes place.
Good sources of protein include lean meats such as chicken and fish, eggs, dairy products like Greek yogurt and cottage cheese, legumes including lentils and chickpeas, and protein-rich plant foods such as tofu and quinoa. Patients who struggle to meet protein needs through food alone may benefit from a whey protein supplement, which is easily absorbed and well-tolerated.
Alcohol should be avoided for at least two weeks before surgery. It interferes with anesthetic drugs, impairs immune function, and negatively affects wound healing. Excessive sugar and processed foods promote systemic inflammation and provide empty calories without meaningful nutritional value. High-sodium foods can cause fluid retention and elevated blood pressure, which complicates anesthesia and increases surgical risk. Patients on blood thinners should be cautious about dramatically increasing vitamin K-rich foods like kale and spinach without consulting their surgeon, as this can interfere with medication effectiveness.
Why Nutrition Matters in Hip Replacement Surgery
The human body undergoes significant physiological stress during and after major surgery. Tissue is cut, bones are manipulated, and the immune system is triggered into a state of heightened activity. All of these processes require raw materials — protein, vitamins, minerals, and calories — to function properly.Research consistently shows that patients who are nutritionally deficient before surgery experience higher rates of postoperative complications, including slower wound healing, increased infection risk, longer hospital stays, and reduced implant stability. On the other hand, patients who are well-nourished before and after surgery recover faster, regain strength sooner, and report better overall outcomes.

Nutritional Assessment Before Surgery
Before undergoing hip replacement, your surgeon or care team may assess your nutritional status to identify any deficiencies that could complicate surgery or slow recovery. Common markers checked include:Albumin and pre-albumin levels indicate overall protein stores in the body. Low levels are associated with poor wound healing and higher surgical risk. Hemoglobin and iron levels determine whether the patient is anemic, which can affect how well the body tolerates blood loss during surgery. Vitamin D and calcium levels are especially important for bone health, since the implant needs to integrate successfully with existing bone tissue.

Pre-Surgery Nutrition: What to Eat in the Weeks Before
The goal of pre-surgery nutrition is to build up the body's reserves so it has adequate resources to cope with surgical stress. The following nutritional priorities apply in the four to six weeks leading up to hip replacement.Protein: The Foundation of Recovery
Protein is the single most important macronutrient for surgical patients. It provides the amino acids needed to repair damaged tissue, produce collagen for wound healing, and support immune function. In the weeks before surgery, aim to consume at least 1.2 to 1.5 grams of protein per kilogram of body weight daily.Good sources of protein include lean meats such as chicken and fish, eggs, dairy products like Greek yogurt and cottage cheese, legumes including lentils and chickpeas, and protein-rich plant foods such as tofu and quinoa. Patients who struggle to meet protein needs through food alone may benefit from a whey protein supplement, which is easily absorbed and well-tolerated.
Iron: Preparing for Blood Loss
Hip replacement surgery involves some degree of blood loss, and going into surgery with low iron stores increases the risk of requiring a blood transfusion. Iron-rich foods such as red meat, chicken liver, spinach, fortified cereals, and lentils should be increased in the pre-operative diet. Consuming vitamin C alongside iron-rich foods significantly improves absorption, so pairing spinach with lemon juice or red meat with bell peppers is a practical strategy.Calcium and Vitamin D: Bone Health Foundation
Calcium and vitamin D work together to maintain bone density and support the integration of the prosthetic implant with surrounding bone. Calcium-rich foods include dairy products, fortified plant milks, almonds, broccoli, and white beans. Vitamin D, which is essential for calcium absorption, is found in fatty fish like salmon and mackerel, egg yolks, and fortified foods. Since vitamin D deficiency is extremely common — particularly among patients who spend limited time outdoors — supplementation is often recommended in the range of 1,000 to 2,000 IU per day, but always under medical guidance.Antioxidants: Reducing Surgical Inflammation
Vitamins C and E are powerful antioxidants that help the body manage the inflammatory response triggered by surgery. Vitamin C is also essential for collagen synthesis, making it directly relevant to wound healing. Load up on colorful fruits and vegetables such as oranges, strawberries, kiwi, bell peppers, carrots, and leafy greens in the weeks before surgery. Nuts and seeds are excellent sources of vitamin E.Hydration
Adequate hydration supports blood pressure regulation, kidney function, and tissue health. Aim for at least eight to ten glasses of water daily in the weeks before surgery. Avoid excessive caffeine and alcohol, both of which contribute to dehydration and can negatively affect anesthesia and recovery.What to Avoid Before Surgery
Certain dietary habits should be actively reduced or eliminated in the lead-up to hip replacement surgery.Alcohol should be avoided for at least two weeks before surgery. It interferes with anesthetic drugs, impairs immune function, and negatively affects wound healing. Excessive sugar and processed foods promote systemic inflammation and provide empty calories without meaningful nutritional value. High-sodium foods can cause fluid retention and elevated blood pressure, which complicates anesthesia and increases surgical risk. Patients on blood thinners should be cautious about dramatically increasing vitamin K-rich foods like kale and spinach without consulting their surgeon, as this can interfere with medication effectiveness.
