Hemodialysis vs. Peritoneal Dialysis

If your kidneys are unable to function on their own, you will need dialysis to help flush toxins from your blood to keep your body healthy. Dialysis replaces the function of your kidneys by removing waste and excess fluid from your bloodstream.

Dialysis can be conducted at home or at a treatment center. For those that go to work, school, have children to care for, enjoy active lifestyles or just want more freedom, home dialysis may be a better option. Unfortunately, not all patients are eligible for each treatment method. Your doctor will be able to diagnose your specific condition and determine which treatment option is best.

Hemodialysis vs. peritoneal dialysis

There are two main types of dialysis to treat kidney failure: Hemodialysis and peritoneal dialysis. Let’s take a look at their differences below:

  • Access site
    Your doctor will create a vascular access site in the arm before hemodialysis. Peritoneal dialysis, on the other hand, requires a catheter, or piece of tubing, placed in your belly.
  • Filter
    Hemodialysis uses a man-made membrane called a dialyzer to clean the blood, whereas peritoneal dialysis uses the lining of your belly.
  • Frequency
    Peritoneal dialysis offers a more flexible dialysis schedule because you will be trained to administer the treatment at home, on your own schedule. Hemodialysis is usually done 3 times per week on a fairly set schedule.
  • Location
    Hemodialysis is typically done in a treatment center three times per week with each session lasting between four and five hours. By contrast, peritoneal dialysis can be done in the comfort of your home on your schedule.

Why it’s Important to Have Healthy Kidneys

The kidneys are two bean-shaped organs that are located just below the rib cage, one on each side of the spine. It’s important to keep these organs healthy because they are responsible for keeping the rest of your body, especially your blood, healthy.

What do kidneys do?

Keeping your kidneys healthy helps keep the rest of your body healthy. In addition to preventing the build-up of waste and excess fluid in the body, kidneys are responsible for:

  • Balancing fluid content in the body (homeostasis)
    For the cells in our body to work properly, it’s important to balance the amount of water we take in and the amount we lose.
  • Regulating the removal of excess fluids
    Cells in your body can be damaged when too much water enters or leaves them.
  • Producing enzymes that help control blood pressure
    To avoid hypertension or high blood pressure, kidneys help regulate sodium and potassium levels.
  • Producing hormones that help make red blood cells
    Red blood cells help transport oxygen throughout the body to keep organs and muscles healthy.
  • Activating vitamin D
    To keep your bones healthy and strong, the kidneys convert vitamin D into its active form to promote healthy growth and remodeling of bone.

How to keep your kidneys healthy

Kidneys are in charge of removing waste from your blood. Keep them healthy with these tips:

  • Stay hydrated
    Water helps kidneys remove wastes from your body through urine. Water also helps keep your blood vessels working well, allowing blood to easily flow to the kidneys.
  • Eat well
    A kidney-friendly diet helps keep your kidneys healthy by reducing your daily intake of protein, phosphorus and sodium.
  • Exercise regularly
    Regular exercise encourages a healthy lifestyle, which in turn helps reduce your risk of obesity, high blood pressure and kidney disease.
  • Say no to tobacco
    Tobacco decreases the amount of blood that can pass through your kidneys by damaging the blood vessels.

Vascular Access Management

A well-functioning vascular access is essential for performing effective hemodialysis. Hemodialysis, or kidney dialysis, is a blood purification procedure. A person with end-stage kidney disease relies on dialysis to mechanically remove fluids, electrolytes and waste products from their blood. Nearly 500,000 people in the United States depend on dialysis to keep their blood free of toxins each year.

What is vascular access?

Vascular access is a surgically created vein that quickly and easily accesses a person’s blood. This access point allows large amounts of blood to flow continuously from the body through a dialysis machine for purification and back to the body.

Proper management of a vascular access

You can avoid complications like infection, stenosis, thrombosis and hemorrhage through proper management of your vascular access point. Here are a few tips:

  • Make sure the dialysis needle stick locations are rotated to prevent stenosis and thrombosis (deep vein blood clots) from forming.
  • Confirm the vascular access is functioning properly several times per day. Our skilled specialists will show you how it is supposed to react.
  • Look for any bleeding following dialysis treatment.
  • Watch for signs of infection around the access point.
  • Keep the vascular access and surrounding skin clean and dry.
  • Avoid any tight-fitting clothing or jewelry to ensure medical professionals can access the site easily.
  • Do not use any creams or lotions on the vascular access site.

Vascular access should be established well in advance of your first dialysis to give the lifeline a chance to mature, so it can be ready to use. If you or a loved one has been diagnosed with kidney disease, contact South Texas Renal Care Group at 844-739-2897 to schedule an appointment.

Top Foods for Healthy Kidneys

Chronic kidney disease affects approximately 31 million adults and is the 9th leading cause of death in the United States. Kidney disease means the kidneys are damaged and can no longer filter blood effectively. This causes a build up of waste in the body, and storing excess waste can have a negative cascading effect on your overall health.

Those who suffer from diabetes and/or high blood pressure are at a heightened risk of kidney disease. You can reduce your risk of kidney disease by avoiding foods that are high in sugar and sodium, eliminating tobacco products and reducing any long-term pain medications.

Top food and beverage choices for healthy kidneys

While some people are genetically predisposed to kidney problems, many can help fortify the health of your kidneys through kidney-friendly food and beverage choices. These include:

  • Water is a natural, sugar-free drink that helps your kidneys cleanse and rid your body of toxins.
  • Cranberries (and 100 percent cranberry juice) prevent the development and growth of ulcers and bacteria in your urinary tract by making the urine acidic, which helps keep bacteria from sticking to the bladder.
  • Red bell peppers are high in lycopene, an antioxidant that protects against certain cancers, like kidney cancer.
  • Apples are a good source of pectin, a soluble fiber that helps lower blood glucose and cholesterol levels.
  • Mushrooms are an excellent source of vitamin D. Vitamin D is extremely important for regulating kidney function.
  • Grapefruit contains the flavonoid, naringenin, which helps decrease the growth of kidney cysts that could lead to kidney failure.
  • Oatmeal is high in fiber, so it’s very effective for controlling blood pressure and cholesterol, two of the most common symptoms of chronic kidney disease.
  • Kale is filled with flavonoids, which offer powerful antioxidant and anti-inflammatory benefits. People with chronic kidney disease often suffer from chronic inflammation as a result. 

Other recommendations for healthy kidneys

It’s also important for those suffering from kidney disease to limit animal-based proteins and phosphorus-rich foods. Generally speaking, meat, dairy, eggs and alcohol are some of the biggest foods to avoid.

Your kidneys are one of your body’s biggest natural detox components; take care of them through a healthy diet. To learn more about kidney health and kidney disease, please contact South Texas Renal Care Group at 844-739-2897. Our experienced kidney specialists are ready to assess your condition, listen to your concerns and design a treatment plan that will meet your individual needs.

Recommended Diet After Kidney Transplant Surgery

If you or a loved one has advanced or permanent kidney failure, your best option for treatment may be a kidney transplant. A kidney transplant is when a kidney that no longer functions properly is removed and replaced with a donated kidney.

While a kidney transplant is not a cure for kidney disease or renal failure, it is a highly effective treatment. People who receive a new kidney are required to take medicine for the rest of their lives — lives that can, for the most part, be led normally. One important aspect of post-operative care after a kidney transplant is maintaining a heart-healthy, kidney-friendly diet. This will not only help keep your kidneys functioning well, it will help you live a healthier, longer life.

Recommended diet post kidney transplant surgery

Good nutrition plays a key role in successfully recovering from a kidney transplant. Here are some recommendations to keep you and your new kidney healthy:

  • Drink plenty of fluids – Dehydration can be harmful to a new kidney, be sure to drink plenty of water.
  • Increase your protein intake – You need more protein than normal to heal and fight infection following surgery. Fill your plate with lean means, poultry, fish, low-fat or non-fat milk, yogurt, cheese, eggs (or egg substitutes), nuts, peas and soy-based foods.
  • Decrease your potassium – Transplant medications may cause a high potassium level in your blood, try to AVOID foods high in potassium like melons, bananas, avocados, oranges, potatoes, tomatoes, dark leafy greens, chocolate, and lentils.
  • Avoid foods high in sodium – Limit sodium to help control fluid retention that could send your new kidney into overdrive, AVOID foods high in sodium like cured meats, lunch meats, pickles, olives, frozen or canned foods with more than 600 mg of sodium per serving, as well as fast foods.

It’s important to follow a heart-healthy diet to control your weight and lower your risk of high cholesterol, high blood pressure and diabetes. High cholesterol, if left untreated, can clog the renal arteries and limit blood flow to the kidneys, causing kidney failure. Contact the experienced transplant team at South Texas Renal Care Group at 844-739-2897 for more information about our compassionate, experienced kidney transplant surgery team.

Supplements for Kidney Health

To take supplements, or not to take supplements. It may seem like a simple question. But if you or a loved one has kidney disease or is undergoing dialysis treatments, the answer might not be. The reason? Your body may need more of certain vitamins and minerals, but at the same time, there may be supplements you should avoid. 

The scoop on vitamins and minerals

Humans need vitamins and minerals because our bodies cannot produce them on their own. Vitamins and minerals are substances that aid body function by using the foods you eat. They give you energy, help the body grow and repair tissue, and more.

Nearly all vitamins and minerals come from food. For people with healthy kidneys, it’s much easier to consume nutrients from a balanced diet. But if you have kidney disease or are on dialysis, you may have limits on the types of foods you can eat. In this case, you may not be getting all the vitamins and minerals you need each day.

Supplements for kidney health

Depending on your current health status, health history and blood test results, your doctor may recommend some of the following supplements:

  • B complex – This group of vitamins consists of vitamins B6, B12 and folic acid.
  • Additional B vitamins – Thiamine, riboflavin, pantothenic acid and niacin help to change the foods you eat into usable energy.
  • Iron – Taking medicine to treat anemia? You may also need to take an iron supplement orally or via injection. You should only take iron if your doctor prescribes it for you.
  • Vitamin C – Works to keep different types of tissue healthy and to help wounds and bruises heal faster.
  • Vitamin D – Can be given as a pill or to dialysis patients during dialysis treatment. Vitamin D supports healthy bones, and recent research suggests it may also guard against heart disease. There are different types of vitamin D, so your doctor will be very specific about the type and amount you should be taking.
  • Calcium – Calcium supports bone health, but in excess, can adhere to phosphorus and deposit in the heart, blood vessels, lungs and other body tissues. Be sure to take only the prescribed amount of calcium.

Supplements that may not be kidney-friendly

For some people with kidney disease, certain vitamins and minerals should be avoided. Some of these include vitamins A, D, E and K, which can build up in the body and cause dizziness and nausea; even death. You should only take these vitamins under strict physician prescription and supervision.

For other people with kidney disease, there are concerns with vitamin C in large doses. Higher amounts of vitamin C may cause a buildup of oxalate, which can cause pain and other issues in the bones and tissues over time.

Managing Kidney Disease

If you or someone you love is living with kidney disease, it’s important to know there are many ways you can manage it. When your kidney function declines and you’re diagnosed with kidney disease, the first step you take will be focused on slowing additional damage to your kidneys and renal system.

Five ways to manage kidney disease

Stay in close contact with your doctors 

Kidney disease is a serious condition and your doctors need to know about any changes in your health as they happen. Regular communication with your doctors will help you get the best medical care, treatment and medication. It will also help you cope with the changing demands of the disease.

Eat for a diabetic lifestyle

Limiting certain ingredients in your diet like sodium, phosphorous and potassium can help slow the effects of kidney disease. Avoid foods like cured or canned meats, nuts, whole grains, dairy, dark leafy greens, potatoes, avocados and mushrooms. You’ll also want to look for hidden phosphates in bottled drinks or iced tea. Reducing protein can help reduce the amount of work your kidneys have to do each day. Many people who suffer from kidney disease are also required to limit their fluid intake to avoid fluid retention in the body.

Manage blood pressure and diabetes

These are two main causes of kidney disease. Monitoring your blood pressure regularly with an at-home kit, or a drug store that offers free blood pressure checks and making adjustments to your diet and daily activity will help keep your blood pressure at a healthy level and control your diabetes — both of which help slow damage to your kidneys.

Keep a healthy lifestyle 

Make sure you are getting regular exercise, maintaining a healthy weight and avoiding tobacco products. In addition to living a healthy lifestyle, you may also need regular tests to determine how well your kidneys are working.

Take medications as prescribed

Most people who suffer from kidney disease will need multiple medications to assist with kidney function and manage other health conditions like diabetes and high blood pressure. Kidney medication helps make it easier for them to function, and helps them function as well as they can.

How Does Dialysis Treatment Work?

If you or a loved one has been recently diagnosed with kidney disease, you probably have a lot of questions, concerns and worry. While being told you have kidney disease is never welcome news, dialysis is a treatment that can help. Dialysis replaces the many vital functions of the kidneys and restores your blood to a normal, healthy state.

What do kidneys do?

Healthy kidneys work hard day and night to filter out harmful waste and excess fluid from the blood. This process keeps your blood healthy and you body functioning properly. Every day, these bean-shaped organs process 120 to 150 quarts of blood and produce approximately one to two quarts of urine. They are also responsible for regulating the amount of sodium, phosphorus and potassium in your body.

How does dialysis treatment work?

Dialysis is an artificial replacement for lost kidney function and is often used as a holding measure until a kidney transplant can be performed. Dialysis can help otherwise healthy people live full and active lives.

Before beginning dialysis treatments, your doctor will insert a fistula or catheter into your vein to help your blood to flow more easily from your body to the dialysis machine. Before your treatment, your doctor may give you a numbing medicine to eliminate any discomfort you may feel while the needle is inserted into the fistula or catheter. The needles are essential because they create a complete loop through the pump and filter of the dialysis machine.

What happens during dialysis treatment?

Your blood will flow from your body through the dialysis machine and back again. The process generally takes about three hours per session. Your blood pressure, weight and temperature will be taken before and after the procedure to confirm enough waste has been removed and you are in a condition that is suitable for leaving the facility.

Your doctor will then turn on the pump of the dialysis machine and set a timer. About every half hour your blood pressure will be taken to ensure it does not become too low. Low blood pressure can occur when too much fluid is removed from the blood.

What happens after treatment?

Following treatment, you may experience fatigue or physical weakness. This may last anywhere from 30 minutes to 12 hours. To help avoid or limit any fatigue and physical weakness, you may need to lengthen the time between your dialysis treatments. Lengthening the time in between dialysis treatments will help remove waste more slowly and lessen the severity of any side effects.

While dialysis can be uncomfortable, it’s a necessary treatment for those suffering from kidney disease or kidney failure. If you’re interested in learning more about dialysis treatment or in-home dialysis treatment, please contact experienced doctors at South Texas Renal Care Group. We are ready to support your kidney health and provide compassionate care during your dialysis treatments. Contact us today to schedule an appointment at 844-739-2897.

Earn a Bike Event


On March 26th, the team at South Texas Renal Care Group partnered with North Park Subaru to sponsor the Siclovia “Earn-a-Bike” program that awarded deserving youth from lower income neighborhoods the opportunity to earn a brand new bicycle. Attendees participated in a three-step process that empowered and promoted safe cycling and a healthy lifestyle.

Children were paired with volunteers who helped them assemble their bicycle. After the bikes were put together, everyone joined a safety cycling workshop and that also highlighted the benefits of living a healthy lifestyle.

To celebrate the accomplishment of the event, participants and volunteers went for a group bike ride around the neighborhood to show off their newly acquired skills.

“It was an honor and a privilege to have the opportunity to partner with Christian Sandoval for Earn-a-Bike and Siclovia San Antonio. Establishing a healthy lifestyle and routine in one’s youth is key to leading a long and healthy life when you’re older. Exercise is a proven way to reduce stress, maintain a healthy weight and prevent diseases like diabetes, heart disease and kidney disease,” said Dr. M. Reza Mizani.

Stay tuned for more events sponsored by the team at South Texas Renal Care Group!

National Kidney Month: Your Kidneys 101

March is National Kidney Month, so it’s the perfect opportunity to spread awareness about kidney disease and prevention methods so you can keep your kidneys doing what they do best.

What do kidneys do?

Most people have two kidneys, although one is generally more than enough to keep your blood clean and chemically balanced. These organs are located near the middle of the back, below the rib cage on either side of the spine. Everyday, these bean-shaped wonders process about 200 quarts of blood and produce approximately two quarts of waste and excess water. They are also responsible for measuring and regulating the amount of sodium, phosphorus and potassium that goes back into the body.

Tips for maintaining healthy kidneys

The main function of the kidneys is to extract waste from your blood, so it’s important to keep them healthy. A few tips to help them work properly:

  • Hydrate
    Your kidneys need fluid to help push toxins and waste out of the blood and eventually out of your body. Drink the recommended eight glasses of water per day and keep things moving along to encourage healthy kidneys.
  • Eat healthy
    Maintaining a healthy diet is good for so many reasons. When it comes to your kidneys, you should avoid foods high in salt and sugar to help prevent diabetes and high blood pressure.

  • Lower your (high) blood pressure
    Often associated with diabetes and high cholesterol, high blood pressure is one of the most common causes of kidney disease. By making a few small lifestyle changes, like eating a healthy diet and reducing the amount of sodium and alcohol you consume, you can begin to lower your high blood pressure.

  • Exercise
    Regular exercise helps reduce your risk of excessive weight gain, high blood pressure and kidney disease. Try taking a brisk walk each day to get your blood circulating.
  • Avoid tobacco products
    The chemicals in tobacco harm your blood cells — among many other things — which decreases the amount of blood that can pass through your kidneys.

One in three Americans are at risk of developing kidney disease, so the experienced doctors at South Texas Renal Care Group are ready to help support your kidney health. Contact us today to schedule your kidney screening at 844-739-2897.
