Is cbd oil safe for kidneys

CBD Effects on Kidneys

Cannabidiol, also known as CBD, has become quite popular. Its popularity has peaked over recent years, with adverts everywhere, from the internet, billboards, television, and even social media. Currently, kidney disease is the ninth most common cause of death in the United States , and things are not getting any better. A common symptom is having physical and emotional pain, that will vary its intensity depending on the patient. Doctors usually prescribe painkillers as a treatment for the pain, but they are usually excreted by the kidneys, which could lead to more kidney damage. With all that it might offer, how could the effects of CBD impact the kidneys?

CBD, according to studies, may be able to help alleviate pain. Early trials of CBD have revealed that it may also help the kidneys due to its potential anti-inflammatory properties, pain management, blood pressure stabilization, and anxiolytic properties. Let’s take a deeper look at the effects of CBD on the kidneys.

What Is CBD and Its Potential Effects on the Kidneys?

Cannabidiol (CBD) is a compound derived from the cannabis plant. Unlike its other counterpart Tetrahydrocannabinol (THC), CBD is non-psychoactive; hence it will not make you high. It might also be a viable option for alleviating aches, symptoms of anxiety, and inflammation. The advantage that CBD may have over other pain medications such as acetaminophen is that the latter is metabolized by the liver and eventually eliminated by the kidneys. They also might damage the cells in the kidney, therefore worsening the condition. CBD, on the other hand, is also metabolized by the liver, but it does not appear to cause any damage to the kidneys, as it is not toxic.

Some of the potential effects of CBD on the kidneys are as follows:

  • Has the potential to help to reduce inflammation in kidneys
  • May help alleviate pain associated with the side effects of the kidney ailments
  • Could help to slow the progression of kidney disease
  • May aid in the prevention of oxidative damage in the kidneys

What Is Kidney Disease?

The kidneys are bean-shaped organs that are situated on either side of the torso. Their primary role is to clean the blood and extract all the excess fluids in the body. The fluids are then removed from the body as urine. They play a crucial role in the filtration of blood in the body. Therefore, the kidneys are crucial to the body, and once they get impaired in their functions, there can be serious implications.

Usually, you can live a long and healthy life without one kidney, so kidney donors and the recipients survive for many years. However, if both of your kidneys fail, then you will be in a traumatizing condition. This is because the condition is fatal; you would need to have a kidney replacement done to survive.

Kidney disease can be acute, and in severe circumstances, become chronic. Below are the different types of kidney disease:

Chronic Kidney Disease

This is the most common form of kidney disease, affecting millions of people all over the world. In fact, most people do not even realize that they have it, which can be quite daunting. Unfortunately, chronic kidney disease does not get any better with time but only worsens. It happens when waste builds up in the body since the kidneys are not working as they should. In the advanced stages, the kidneys may fail altogether, becoming life-threatening. Here, you may need dialysis to remove the excess fluids.

Glomerulonephritis

Glomeruli are usually the tiny blood vessels where cleansing of the kidneys take place. This condition is therefore caused by congenital conditions, some drugs, and infections that can make the glomeruli inflamed. The symptoms usually include foamy urine, retention of fluid, and brown or pink urine. The good news is that glomerulonephritis resolves itself with time.

Kidney Stones

The kidneys clean numerous materials from the blood. An example of this is mineral particles. Over time, these minerals crystallize and form kidney stones. Many people are usually able to pass the stones out through urination; however, the process can be quite painful. In severe cases, you may need surgery to remove them.

Pyelonephritis

This is a condition in which the kidneys get inflamed due to bacterial infections. It can damage the kidneys permanently and even be fatal. Symptoms of this condition include fever above 102°F, cloudy urine, painful urination, and pus in the urine. You may also experience nausea and vomiting. It can be treated with antibiotics, and in severe cases, you may need to be hospitalized.

Polycystic Kidney Disease

It is common for the kidney to form cysts or fluid sacs on its surface. Most of them are usually benign and have no severe side effects. Polycystic kidney disease is a genetic condition that will cause the kidneys to grow numerous cysts all over the surface. It can even lead to kidney failure if the cysts interfere with the regular functioning of the kidneys. However, if both of your kidneys fail due to polycystic disease, you might need dialysis.

The Effects of Kidney Disease

Below are some of the effects seen in result to kidney disease:

  • Bleeding disorders
  • Lowered immune function
  • Anemia
  • Heart failure
  • High blood pressure
  • Skin disorders
  • Neurological disorders
  • Acidosis
  • Hypercalcemia
  • Hyperkalemia

Causes of Kidney Disease

On a typical day, the kidneys usually filter around 180 liters of blood . One of the most common causes of kidney disease is diabetes. Diabetes usually leads to high sugar levels that tend to damage the body tissues, including the kidney nephrons. The other most common cause of kidney disease is hypertension. It does this by reducing the blood supply and the autoregulatory sensitivity of the kidneys. Therefore, the nephrons get damaged, causing a strain on the other remaining nephrons, hence increasing their chances of getting damaged. The other causes of kidney disease include:

  • Heart disease
  • HIV/ AIDS
  • Lupus
  • Obesity
  • Smoking
  • Hepatitis B and C

CBD and Kidney Disease: Where Does It Fit?

CBD is not a cure for kidney disease, but how might the effects of CBD impact the kidneys? The body has CB1 and CB2 receptors that help with bodily functions. When you take CBD, it might stimulate the production of natural cannabinoids, which attach themselves to these receptors and help provide a homeostatic balance to the body. Cannabinoids from CBD also interact with these receptors, which is thought to also aid in homeostasis.

The other effect of using CBD is that it might help promote renal function. It has the ability to protect the nephrons from inflammatory and oxidative damage due to its anti-inflammatory properties.

CBD may also promote the normal functioning of the glomerulus. It might also help to prevent the malfunctioning of the body’s filtration mechanisms depending on the type of kidney injury.

Below are ways in which CBD effects may help reduce the symptoms of kidney disease:

Pain Management

CBD is thought to be an analgesic and has been seen to help reduce pain in arthritis and other conditions. CBD enhances the function of the endocannabinoid system (ECS) by blocking the FAAH, a fatty acid used to break down anandamide , and keep more of it in the body. The anandamide binds to the CB1 receptors to help control your pain response. Kidney disease is harrowing, due to the inflammation of the organ, incisional pain from kidney surgery, kidney stones, and even dialysis.

Inflammation Reduction

According to studies, CBD may have anti-inflammatory properties. Since most kidney diseases are usually inflammatory, then CBD might have a positive impact on the inflammatory symptoms. This is done due to its ability to stimulate the endocannabinoid system.

Reduces Nephrotoxicity

The presence of toxins in the renal tissue is known as Nephrotoxicity. These toxins affect the renal function of the kidneys and affect the normal functioning of the organ. CBD might help reduce drug-induced Nephrotoxicity through its relationship with the cannabinoid receptors. This, therefore, may help promote kidney health.

Diabetes Prevention

Diabetes is an inflammatory condition that usually affects the regulation of blood sugar by the body. According to studies, CBD may be able to reduce inflammation. Since diabetes is one of the risk factors of kidney disease, CBD may be able to help.

What Is the Recommended Dosage of CBD?

One of the crucial things that you need to note is that you should talk with your doctor when you want to start taking CBD. This is especially true if you have any health conditions or are taking any medications. CBD can interact with certain medications, so it’s always best to speak with your doctor before starting CBD.

Finding the right dose of CBD may seem daunting, as it affects people differently. Therefore, it is advisable to follow the manufacturer’s instructions and start low and slow. Note how your body is responding and adjust as needed.

Final Word

Kidney disease is a severe condition that can be fatal in severe cases. More research is needed before we fully understand the effects of CBD on kidneys. However, CBD does appear to have several potential benefits. Remember to always consult with your doctor before starting CBD. When looking for the right CBD product for you, search for a trusted and transparent source. Reliable manufacturers will provide third-party lab tests and a certificate of analysis.

CBD Oil Side Effects on Kidneys: What Studies Found

Chronic kidney disease (CKD) and kidney injury are two significant threats to renal function. Depending on the cause, kidney health issues can – at best – affect your quality of life and – at worst – be fatal.

Conventional treatments have existed for quite a while, and some are very effective. Unfortunately, the potential adverse effects can make those options unbearable. Naturally, some people with chronic kidney disease or kidney injury (among others) decide to look outside mainstream options.

Cannabinoid medicine exploded in recent years, with millions claiming cannabidiol (CBD) helped relieve their symptoms where prescription medication doesn’t cut it.

So how can CBD oil help with chronic kidney disease – or any renal disorder? It’s a complicated topic that, despite some research, leaves more questions than answers.

What is CBD Oil?

If you’re familiar with CBD, you likely know about CBD oil. Content and potency vary depending on the oil and brand. But at its core, CBD oil is a type of natural extract from all forms of cannabis Sativa L. – the plant species often (incorrectly) separated into “marijuana” and “hemp.”

Manufacturers extract the CBD and other compounds using methods like hydrocarbon (butane), alcohol, or CO2. Once separated, the CBD is infused into a carrier oil, like MCT, grapeseed, hemp, or coconut.

You then ingest a pre-measured amount based on your CBD dosage needs. But although many claim CBD works for symptom management, there are also CBD oil side effects to consider. We’ll get to that shortly.

How CBD is Absorbed Into the Body

CBD is absorbed into the body using a vast internal network known as the endocannabinoid system (ECS). The ECS consists of specific pathways known as the CB1 and CB2 receptors located in the central nervous and peripheral systems.

Cannabinoids like THC bind to both the CB1 and CB2, which is why recreational or medical cannabis users experience mental and physical effects.

Other cannabinoids interact with just one receptor, but CBD is one of many exceptions. Instead, cannabidiol impacts other receptors and pathways, ultimately altering the shapes of the CB1 and CB2 receptors.

This reaction affects how external (phytocannabinoids) and internal (endocannabinoids) affect the brain and body. These “adjustments” are often beneficial, as are CBD’s interactions with the serotonin, vanilloid, and other vital receptors.

But before it can do all of that, CBD needs to get into your bloodstream. There are several ways to do this. All consumption methods have advantages and disadvantages, which alter the strength, duration, and effects of CBD.

Those being treated for chronic kidney disease or (other kidney diseases) should also consider potential drug interactions.

Smoking

Inhalation offers a more authentic experience for vape and joint smokers. When consumed through the lungs, CBD hits the bloodstream almost instantly. As a result, you notice effects within minutes. However, the effects wear off faster than any other method – usually within two to four hours.

Many vendors don’t offer inhalable products, often due to health concerns. We’re all aware of the vape illness epidemic that dominated the news in 2019 (and continues to this day). We also don’t know the long-term damage of inhaling burnt cannabis plant matter – although it seems safer than tobacco.

Ingestion

Ingestion offers a broad range of options for taking CBD. Cannabidiol extracts can be infused into hundreds of foods and drinks, from desserts smoothies – even beer and wine! A few examples are:

With ingestion, the majority of CBD is broken down in the liver. Consequently, eating or drinking CBD is the slowest-acting option. But it makes up for this by lasting up to eight hours – longer than any other method.

Topicals

Topicals are another diverse group of CBD products. But unlike smoking and eating, topicals don’t enter your bloodstream. Applied directly to the skin, these products provide a more focused, instant effect.

Is CBD Oil Excreted Through the Kidneys?

We know how CBD enters the body, but how does it leave? Considering urine tests are a common way to detect drug use, you’d think the kidneys eliminate a lot of THC and CBD. But a 2019 review in the Canadian Journal of Kidney and Health Disease shows that nothing could be further from the truth.

The authors explain THC and CBD mostly exit through the feces. As a result, they feel CBD’s minor effects on kidneys don’t require a CBD dosage adjustment. However, they’re unsure if we eliminate minor cannabinoids in the same fashion.

What are the Side Effects of CBD Oil?

Studies universally found that CBD is well-tolerated with no possibility for abuse or addiction. Side effects of CBD oil are mild, especially compared to prescription medication. Still, it might not be for you. Keep an eye out for some common side effects:

  • Dry mouth
  • Appetite changes
  • Nausea
  • Fatigue
  • Insomnia
  • Dizziness
  • Diarrhea

High doses of CBD – especially when introduced immediately without titrating – are more likely to trigger those effects. If these problems persist or worsen, stop using CBD.

Since hemp oil contains little to no tetrahydrocannabinol (THC), CBD extracts shouldn’t make you high. However, if you feel intoxicated, it’s possible the manufacturer mislabeled their product.

Common Causes of Kidney Disease

According to the National Institute of Diabetes and Digestive and Kidney Diseases, chronic kidney disease (CKD) is usually caused by diabetes or high blood pressure.

However, there are many other reasons, including (but not limited to):

  • Drug interactions
  • Poison
  • Infection
  • Physical injury
  • Genetics

Symptoms of Kidney Disease

The symptoms of kidney disease can be difficult to pinpoint since various common infections or toxins often cause them. However, if you have high blood pressure or diabetes, pay extra close attention to the following signs:

  • Nausea and vomiting
  • Back pain
  • Increased or decreased urination
  • Fatigue
  • Sleep issues
  • Muscle cramps
  • Dry or itchy skin
  • Swelling of the feet or ankles
  • Chest pain
  • Shortness of breath
  • Hypertension (high blood pressure)

Regardless of the cause, chronic kidney disease is a serious threat to kidney function. If you’re concerned about your renal health, talk to a doctor as soon as possible.

Does CBD Oil Hurt Your Kidneys?

CBD oil may hurt the kidneys, but it also might help renal function. Preliminary research is either promising, inconclusive, or negative.

We’ll look at all the results next.

What Studies Say About CBD Oil Side Effects on Kidneys

The relationship between chronic kidney disease (or any other kidney health issue) and CBD oil isn’t well understood. Some research looks positive.

For example, a 2009 Study in the Journal of Pharmacology and Experimental Therapeutics discovered that CBD might help alleviate inflammation, oxidative stress, and cell destruction, reducing nephrotoxicity.

“Nephrotoxicity” refers to kidney damage from drugs or toxins. This condition makes it difficult to eliminate urine or waste, leading to a potentially deadly outcome.

The authors of the said review found that the activation of the CB1 receptors regulates renal vascular blood flow. Meanwhile, the renal CB2 receptors reduce the effects of inflammation, oxidative stress, and renal fibrosis. These findings support and explain the 2009 study’s observations.

Subsequent 2017 research in the American Journal of Physiology also concluded that cannabinoids have potentially beneficial effects on kidneys. However, they caution that we don’t know about the effects of CBD on acute kidney injury (AKI) or chronic kidney disease.

The following study shows how accurate this warning may have been.

Among the promising or inconclusive findings are some upsetting discoveries. One 2018 study in the American Society of Nephrology Found that cannabis consumers with impaired kidney function showed a faster decline than non-cannabis users.

One important detail, however, is that these subjects used THC and CBD products. This makes it difficult to determine if CBD or THC is responsible (if at all).

However, the mix of positive and negative findings might be attributed to CBD rather than CBD products. According to

2o2o review from Current Opinion in Nephrology and Hypertension says, “There is no evidence to suggest that CBD has any adverse effect on kidney function. In fact, CBD prevented cisplatin-induced nephrotoxicity in a mouse model by reducing oxidative stress. However, some products may contain toxic contaminants such as heavy metals, pesticides, and solvents.”

So are CBD’s effects on kidneys good or bad? For now, we don’t know. But even if cannabidiol is effective, quality CBD may be hard to find. Without a green light from the Food and Drug Administration, there’s no way to guarantee CBD oil is free of the aforementioned contaminants.

Potential Benefits of CBD Oil in Kidney Diseases

The effects of CBD oil on kidney disease are mostly promising but still warrant caution. But there’s some good news. Even if CBD has no direct therapeutic effects on those organs, chronic kidney disease patients can (and do) use cannabis for symptom control.

The 2020 study above mentions CBD’s potential for pain management. Researchers believe CBD may help mitigate chronic pain related to kidney disease.

They also theorize that maybe CBD’s analgesic benefits could reduce the need for opioids – but that’s an enormous “maybe.”

Dosage and Precautions for CBD Oil and Kidneys

We know very little about the effects of CBD oil on kidneys and next to nothing about the proper CBD dosage. Unfortunately, dosing cannabinoids isn’t an exact science, despite decades of research. Synthetic cannabinoids, like Sativex and Marinol, being are a couple of exceptions.

However, those prescription drugs are designed to treat specific symptoms rather than the broad range of potential benefits assigned to CBD.

It also doesn’t help that we can’t (yet) conclusively prove that CBD oil side effects on kidneys outweigh the possible beneficial effects of CBD.

But if you feel it helps with symptoms like nausea or chronic pain, you can at least benefit from those effects.

In this case, follow the “start low and go slow” rule. Begin with the smallest dose possible (usually 2.5 to 5 mg) and increase every few days as needed.

That being said, don’t try adding CBD to your daily health routine without consulting a doctor – especially if you have kidney disease.

Summary: CBD Oil Side Effects on Kidneys

There’s some promising CBD research that could be a game-changer for those with kidney injury, chronic kidney disease, or other renal function problems.

But while exciting, we need to remember Despite some worthwhile findings, none of the potential benefits have been evaluated by the Food and Drug Administration. CBD oil isn’t intended to prevent, diagnose, or treat any illness.

However, we should see these discoveries as springboards to inspire further research.
