Okay before we go much further let's discuss the functions of the kidneys and how important they are to our overall well being. Our kidneys are 24/7 cleaning machines. These twin shaped organs located below the rib cage work 365 days a year removing waste from the body. Each and every day these organs pump about 200 quarts of blood through about 140 miles of tubes. On top of removing waste products, the kidneys remove extra fluid, produce hormones like Erythropoietin or EPO, and also help maintain the balance of minerals and chemicals to keep us healthy. And we can’t forget to mention one of the most important functions of the kidneys which is to control blood pressure.
High blood pressure affects all the cells in the body including the kidneys which in turn can prevent them from doing their other jobs. This is a major cause of CKD so if you are at risk for high blood pressure it’s very important to get regular checkups and follow your doctor's instructions to keep it under control. I had to make many changes in my diet and lifestyle that included reducing my salt intake. Now I don’t even keep a salt shaker on the table. I have also found it helpful for me to monitor my pressure at home and share these results with my doctor.
Erythropoietin is the hormone which is responsible for directing your bone marrow to make new red blood cells. Without this hormone your red blood cell production declines and you become Anemic. This condition either requires a replacement hormone or a blood transfusion. Many CKD patients, like myself, require injections of a synthetic EPO hormone on a weekly basis. Anemia causes extreme fatigue and overall weakness. Other side effects of anemia include making you feel short of breathe and look pale. For me, anemia has been one of my biggest challenges with CKD. Please see my blog entry "Anemia and Fatigue in CKD" to review information about anemia. Over the last ten years I have needed multiple blood transfusions due to severe anemia.
Symptoms of Anemia include:
1. Looking pale
2. Shortness of breath
3. Trouble sleeping
4. Feeling dizzy and having headaches
I later learned that one of the functions of your kidneys is to make a hormone called EPO. Hormones are secretions that your body makes to help your body work properly and keep you healthy. EPO tells your body to make new red blood cells. When you have kidney disease, your kidneys cannot make enough and this causes your red blood cell count to drop and that’s when you develop anemia.
Most people with kidney disease will develop anemia. Anemia can happen early in the course of kidney disease and grows worse as the kidneys lose their ability to work well and make EPO. Anemia is especially common if you:
1. Have diabetes
2. In stages 3,4, or 5 of kidney disease
3. Are female
But because not everyone with anemia gets symptoms you should have regular blood tests to measure your hemoglobin levels.
Hemoglobin is the part of the red blood cell that carriers oxygen throughout the body. Your doctor can tell if you have anemia by measuring your hemoglobin levels. If your hemoglobin levels are below normal which is 12.0 for women and 13.5 for men. Your doctor will start a treatment plan to raise your hemoglobin. This usually includes drugs that work as an EPO stimulate. These agents are called ESA’s and helps your body to make new red blood cells that your kidneys cannot. It is usually given as an injection under the skin and most CKD patients learn to do this at home as self injections.
The other treatment part of anemia is controlling your iron stores. Your body needs iron to make red blood cells especially when you are receiving an ESA treatment. Without enough iron, your treatments will not work as well. Iron can be given either in pill form or through IV. Your iron stores should be at least 20% and should be checked along with your hemoglobin levels.
Your doctor will check your hemoglobin levels on a monthly basis to bi~monthly basis. This tells your doctor how well your doing and your dose of the ESA will may need to be changed, depending on how well you respond. If untreated, anemia can make your health conditions worse and cause your heart to work harder.
For me one of the most complex issues in dealing with CKD was embracing a renal diet. From day one, the way I approached food needed to change. Throughout every stage of CKD there are different requirements and it was important to educate myself during each stage. Calorie intake, limitations of salt, phosphorus, potassium and protein were all concepts that I had to learn. Some of these things I had never even heard of before I was diagnosed and now I realize the importance of controlling them all. I learned that having proper nutrition can help reduce the workload on the kidneys and allow the best environment for optimal kidney function. This is very important in the first stages of CKD when you still have kidney function.I was never in my life a label reader and once I was diagnosed that all changed. Reading labels can help make healthy food choices for your kidneys.
Sodium: is a major mineral found in the fluid surrounding the cells in the body, It helps to regulate blood pressure and fluid volume. It also helps maintain ph balance in the body. Both muscles and the nervous system rely on sodium to function correctly.
Phosphorus: is a mineral that makes up 1% of a person's total body weight, and is present in every cell of the human body. Most phosphorus is found in the teeth and bones. It plays an important role in how the body uses carbohydrates and fats. It is also needed for the production of protein which is necessary for growth, maintenance, and repair of cells and tissue. It also helps in kidney function, muscle contractions, normal heartbeat and nerve signaling.
Potassium; is a dietary mineral necessary for balancing ph and fluids in the body. It's important to maintain normal blood pressure and works in opposition to sodium. It also is needed for normal muscle growth and function of the nervous system and brain functions.
Some foods high in sodium include: Fast foods and processed foods, canned goods, baked goods, cheese, salted snacks and luncheon meats. High sodium increases the risk of stroke, high blood pressure, heart attack and kidney disease. In dialysis patients it also causes increased edema or swelling in the feet or ankles.Which can lead to breathing issues and pulmonary edema. That's why its so important to limit sodium intake.
Some foods high in phosphorus include: dairy products, chocolate, processed meats, beer, cola's and dark soft drinks, nuts/seeds and dried beans and peas. High phosphorus levels causes your body to pull extra calcium from the bones and can weaken them. When you have both high phosphorus and calcium, which usually go hand and hand, it can lead to dangerous amounts of calcium deposits in the lungs, eyes, heart and blood vessels. You want to maintain a phosphorus level of 3.5 to 5.5 mg/dl.
Some foods high in potassium include: raisins, prunes, dates, strawberries, bananas, watermelon, soy and soy foods, turkey and beef. High potassium levels causes irregular heartbeat, nausea and a slow, weak or absent pulse. Low potassium level causes fatigue, muscle pain, cramps, constipation and dizziness. You want to maintain a potassium level of 3.5 to 6.0 mg/dl,
One of the most important things we discussed was the need for Organ Donors both living and deceased. Today I am waiting with 99,206 others who all need kidneys. All together there are 121,153 in the United States alone who need organ transplants. This is why we have such a dire need for organ donors. Waiting is the hardest part, never knowing if and when the phone will ring. The way I've dealt with waiting is to not think about it. I just deal with the day to day. I do all I can to keep healthy and stick with my dialysis, renal diet. This is why the National Donor Sabbath means so much to me. It is yet another chance to raise awareness to cause that will one day hopefully save my life. My faith has helped me get through so much in dealing with kidney disease. The National Donor Sabbath is a weekend to celebrate, through faith, the need for organ donation and transplant. I hope each of you will take part this weekend. Even if only inspires you to sign up at Donate Life America to be an organ donor! Do it for me, Do it for the 121,153 waiting.
I want to thank each and every one of you for joining me over the last six months. I look forward to 2014 being a better year and I hope it is for you as well. I look forward to your comments, questions or concerns.
Keep on fighting, you Kidney Warriors!
