Eating healthy is the key to staying fit and healthy. Any disease takes a huge toll on the body, especially kidney failure. Kidney failure is treated with dialysis, medication and proper nutrition till the patient can undergo a transplant. With a new kidney, the patient is able to overcome most of the metabolic constraints faced by them. This means they can eat without the stringent restrictions, limitations that had to be followed during treatments. Food has a major role to play in the recovery and health of the individual post-transplant. It is important to eat well to overcome the deficiencies due to the disease process and maintain optimum health and prevent relapse. To understand the dos and don’ts post-transplant, we will break up the journey into two parts. One immediately post-surgery and one for the long term.Also Read: World Kidney Day: 7 Foods To Eat For A Healthy KidneyDiet Post Transplant Surgery:Immediately after surgery, the patient may need to be on a liquid diet progressing to soft foods and then a normal diet. Each hospital has a set protocol. The need for good nutrition is to assist in wound healing, prevent infections and keep the electrolyte balance steady. Once solid food can be started, the following are addressed.HYDRATION: The first need that is addressed immediately after surgery is adequate hydration. This is the key to a good recovery. Drink at least 2 liters/day water. Avoid excessive caffeine intake as it acts as a diuretic.Energy: Adequate calorie intake is necessary to help the body stay energised so that wound healing is faster. 30-35kcals/kg/ day is recommended to meet the needs of the recovery phase. Whole grains like wheat, and oats must be a part of every meal or snack. At this stage, if the digestion is not up to the mark, cereals like rice, sooji, and sago, which are easier to digest, can also be used. Excessive sugar intake is not recommended as most patients are on steroids too.Proteins:Kidney failure is associated with loss of muscle mass, along with the increased need for healing makes it very important to have good quality proteins in adequate amounts daily. Proteins are also needed to help maintain the integrity of the immune system. Add a dal/ paneer, egg, chicken or fish to every meal. In addition, make sure to consume adequate dairy for the calcium it provides.Potassium: is an electrolyte every kidney patient is familiar with. Post-transplant, the medical team keeps a strict eye on this mineral. The blood levels are a good tool to help you choose K-rich foods like lemons, peaches, and bananas or avoid them if needed.Sodium (Na) is another electrolyte that has a major significance to gauge the health of the kidney. While in the hospital, the nutrition team will give you some extra salt when needed.Raw foods like salads and fruits and uncooked sprouts will be avoided to prevent the entry of microbes as the immune suppressants in your prescriptions also downgrade the immunity shield. Preventing infections is of prime concern.Certain foods like pomegranate and grapefruit must be avoided as they are contraindicated along with immunosuppressant drugs.Also Read: 8 Diet and Lifestyle Changes That Can Help Prevent Kidney DiseaseLong-Term Diet Post-Transplant SurgeryOnce you recover from the surgery and are stable, diet will continue to play a vital role in long-term health.
