Can CBD Oil Cause Gastritis


Buy CBD Oil Online

Gastritis is inflammation of the stomach lining. The severity of the condition ranges widely and many with the condition are wondering if marijuana can help. Cannabidiol is a molecule contained in hemp. It is used to conceive CBD which acts against the evils that can generate gastritis. To better understand the effects of this substance on gastritis, it is necessary to know the virtues that allow it to fight against this evil. Discover in this article the different side effects that can cause CBD.

Gastritis and Medical Cannabis

Did you know that 34.7% of the population in developed countries has gastritis? This figure jumps to 50.8% in developing countries (3). Individuals who are diagnosed with this illness will experience pain and discomfort as a result of the stomach lining becoming eroded, irritated, and/or inflamed from a variety of underlying causes.

The name “gastritis” speaks for itself, with “gastr-” being a word to describe the stomach and “-itis” referring to inflammation. A burning inferno of pain tears through the stomachs of gastritis patients and the medical condition can occur either suddenly (acute) or gradually (chronic).

In many instances, gastritis is a lifelong disease and it is unlikely for the patient to become spontaneously healed. Gastritis and duodenitis cost the country’s healthcare system more than $1 billion every single year (6).

The good news is that several treatment options may help to diminish the symptoms. One example is cannabis which, according to a study published in the journal of Alcoholism, Clinical and Experimental Research , may help alcohol abusers to reduce their risk of developing alcoholic gastritis (2). Early published research also offers similar promising results.

Gastritis Signs, Symptoms and Types

Generally, gastritis is classified as either ‘Type A’, ‘Type B’, or ‘Type C’. It happens after the stomach lining (mucosa) becomes damaged or weakened by chemical or infectious irritants, including alcohol, bile, and non-steroidal anti-inflammatory drugs (NSAIDs). It may also occur after eating spicy food or with an H. Pylori infection.

What are the Main Gastritis Symptoms?

Not everyone who is diagnosed with gastritis will experience gastritis symptoms. However, the most frequently reported symptoms to include:

  • Abdominal pain and/or bloating
  • Black, tarry stools
  • Burning feeling deep inside the stomach after eating/during the nighttime
  • Hiccups
  • Indigestion
  • Loss of appetite
  • Nausea
  • Stomach acid
  • Stomach pain
  • Vomiting

If you experience symptoms like these visit to your doctor as soon as possible to prevent further complications and detect serious causes.

How is Gastritis Diagnosed?

Before you can consider your treatment options, you must first consult with a doctor about your symptoms and medical history, as well as any specific medicines you might already be taking. When you visit your doctor, expect to undergo a physical examination.

Depending on the results of the exam, your doctor may ask you to undergo one of the following types of tests:

  • Upper GI endoscopy – An upper GI endoscopy is a minimally invasive procedure that allows a doctor to examine small pieces of tissue from your stomach lining under a microscope to diagnose and figure out the possible cause(s) of gastritis or gastropathy. This procedure involves the use of an endoscope, which is a flexible tube fitted with a special camera. During an endoscopy, the doctor will inspect your upper GI tract, which includes your duodenum, esophagus, and stomach.
  • Blood Tests – Doctors may also carry out blood tests. This method is pretty straightforward and involves a needle to prick your skin, before drawing a blood sample using an attached syringe. This sample will then be sent to a lab and you will be informed of the results at a later date.
  • Stool Tests – Stomach bacteria, such as H. pylori infection, is a common cause of gastritis. Infections of this kind can be detected with a stool test, which can also be used to check bloody, black, or tarry stools (major signs of bleeding in the stomach).
  • Urea Breath Test – When testing for H. pylori infection in the digestive system, doctors may conduct a rapid diagnostic procedure known as a ‘urea breath test.’
  • Upper GI Series – To get a closer look at your upper GI tract, doctors may also take a standard series of fluoroscopic X-rays.

Gastritis Causes and Complications

Poor eating, drinking, and lifestyle habits and/or the use of specific medications, including anti-inflammatory drugs, can trigger the onset of gastritis. Two prime examples are stress and excessive alcohol consumption. Additionally, if you suffer from chronic vomiting, bile reflux, or Helicobacter pylori ( H. pylori ), you may be at a higher risk of developing gastritis.

When left untreated, gastritis can cause erosion of the gut lining, nausea and vomiting, severe blood loss and diarrhea. In advanced cases, acute gastritis and chronic gastritis can increase the risk of developing peptic ulcers and stomach and colorectal cancer. Often fatal — 11,090 deaths are predicted to happen this year alone — gastric cancer is sometimes treatable with chemotherapy, chemoradiation, radiation therapy, and targeted therapy (8). Colorectal cancer is even more prevalent and estimated to cause over 50,000 deaths in 2022 alone. Fortunately, it can be detected and treated early with routine monitoring and prevention strategies (8).

Gastritis Treatment: Can Cannabinoids Provide Relief?

Antacids are usually the first medicine of choice for people who suffer from acute gastritis. Alka-Seltzer, Maalox, Mylanta, Rolaids, and Riopan are some common over the counter antacids, which are designed to neutralize the acid in your stomach and relieve heartburn/indigestion.

Typically, OTC brands will blend aluminum, magnesium, and calcium with bicarbonate ions or hydroxide to produce antacids. Despite the efficacy of chewable or liquid antacids, the unwanted side effects often leave people struggling to pass stools or, on the other end of the spectrum, glued to the toilet with a bad case of diarrhea!

The most commonly prescribed antacids, however, are medications like H2 receptor blockers such as famotidine and ranitidine, and especially PPIs (proton pump inhibitors) like omeprazole and pantoprazole. These work to effectively reduce the natural acid production in the stomach and decrease the symptoms of gastritis and its complications. Your doctor or GI specialist will most likely recommend these.

Fortunately, there is a light at the end of the tunnel for people who’ve exhausted alternative treatment options: cannabis use. Although more studies are set to take place, some doctors are encouraged by the existing scope of research that suggests marijuana use may possess properties to relax the muscles, reduce pain, relieve inflammation, enhance nerve-muscle coordination, ease spasms, and prevent/reduce nausea and vomiting (antiemetic).

Synthetic and natural cannabinoids can activate cannabinoid receptors in the ECS to reduce gastrointestinal fluid secretion and gut inflammation in animal and human cell in-vitro models (4, 5). Specifically, cannabis use in the form of CBD oil may potentially ease inflammation and other symptoms in the gut, however this is yet to be definitively proven in any clinical studies. Anecdotally, however, cannabis has been reported by patients to help to ease the symptoms of irritable bowel syndrome (IBS) , irritable bowel disease (IBD), and other types of digestive disorders such as abdominal pain, appetite, nausea, vomiting, diarrhea, cramps, and overall quality of life (7).

The Role of the Endocannabinoid System in Treating Gastritis

Cannabis gets to work by communicating with cannabinoid receptors in the digestive tract. Cannabinoid receptors make up part of the endocannabinoid System (ECS) , which is responsible for maintaining homeostasis. Some studies have demonstrated cannabis’ neuromodulatory capability in controlling the functioning of the gastrointestinal system.

While it might be one of the most expressed systems in the human body, the ECS is one of the least studied. Among its many functions, the ECS majorly influences the regulation of the gastrointestinal tract. Cannabis is heavily involved in regulating food digestion and since food is fuel for the body and mind, the potential of using cannabis for gastritis cannot be ignored.

A group of scientists fronted by Israeli researcher Raphael Mechoulam first discovered the existence of the ECS in the mammalian GI system back in the year 1995 when the endocannabinoid 2-arachidonoylglycerol (2-AG) was isolated in the canine intestine (6).

CB1 receptors can be found pretty much everywhere in the brain, lungs, liver, and kidneys. They have also been widely discovered in the colon and stomach, with the majority found on the intestinal wall’s lining cells, A.K.A. “the epithelial cells”.

Even more interesting is the fact that CB1 receptors are present in neurons that control the GI system’s primary functions. Conversely, CB2 receptors are found in the Enteric Nervous System, but most are found on the immune cells in the GI tract.

While CB2 receptors are well-known to modulate inflammation, CB1 receptors may also play a positive role. There are certain compounds different from CBD and THC that can change the way CB1 receptors work and increase gastroprotection from things like NSAID-caused gastritis (9).

Recent research has also found that recreational cannabis use is associated with a decrease in the risk of developing an H. pylori infection (1).

Over time, accumulated research has shown the ECS is “a key modulator of gastrointestinal physiology, influencing satiety, emesis, immune function, mucosal integrity, motility, secretion, and visceral sensation (6).” Cannabinoids may also play a key role in the health and function of gut microorganisms, which may in turn improve human health although a definitive link has not been found.

What Preparations of Cannabis are Best for Gastritis?

Since gastritis occurs deep within the belly, it’s not possible to apply a topical gel or lotion to relieve the symptoms. Instead, for fast-acting relief, you may consider inhaling your cannabis in the form of a vape or smokable dry flower. Expect the effects of cannabis to reach their peak within 30 minutes and last for up to six hours with this administration method.

Another type of cannabis administration that is recommended for gastritis patients is ingesting edibles, tinctures, and/or infused drinks. When ingesting cannabis, the effects of THC (tetrahydrocannabinol), CBD (cannabidiol), and other cannabinoids can be felt within 30 minutes to two hours. Expect the effects of cannabis to linger for 5-8 hours with this method of administration.

Today there is not enough research in order to recommend one form of cannabis over the other for the symptoms of gastritis, and it has not been shown to treat, mitigate, or prevent gastritis or its underlying causes or complications.

Talking to Your Doctor About These Types of Treatments

If your doctor has reason to believe that you have gastritis, you will likely be referred to a gastroenterologist (a doctor who specializes in digestive disorders.) They should be able to conduct the necessary tests to assess your health status, as well as point you in the right direction in regards to a specific type of treatment that will best suit your lifestyle and the severity of your symptoms.

With a growing body of scientific research highlighting the remedial qualities of smoking weed for gastritis patients, it’s not surprising that more people are turning to the plant as a therapeutic aid for gastrointestinal problems. Consulting with a doctor before using cannabis-based treatments is vital, especially if you are already using a specific type of medication that might react synergistically when consumed alongside cannabis.

As long as you reside in a state that has medical cannabis-friendly laws, you can organize a face-to-face consultation with a licensed healthcare practitioner or doctor who is certified to recommend cannabis treatments.

Complementary Gastritis Treatments Worth Discussing with Your Doctor

Getting your health back on track after a gastritis diagnosis requires some serious lifestyle changes. If you’re a regular user of alcohol, your doctor will advise you to quit or at the very least, reduce your intake. Some other substances that should be avoided include coffee, citrus fruits and juices, acidic foods, NSAIDs, and certain other drugs.

There are a handful of complementary treatments that can ease the symptoms of gastritis, including yoga, Tai Chi, meditation, and stress-busting breathing techniques.

Chinese herbal decoction (CHD) has also been tried and tested in the treatment of atrophic gastritis (AG). This herbal-medicine technique involves boiling herbal or plant material, including bark, roots, and stems, to extract essential chemicals.

Does CBD have any effect on gastritis?

Gastritis is one of the most painful conditions that human beings can suffer from. This ailment leads to unbearable stomach pain in the sufferer. Until now, very few natural treatments have been able to relieve the symptoms of this disease. It is then appropriate to ask whether CBD manages to curb it. This questioning must be answered in the affirmative. CBD has many properties that allow it to act effectively on the endocannabinoid receptors of the human body.

Gastritis is a gastrointestinal condition resulting from inflammation of the stomach lining. This is then categorized in the group of inflammatory diseases of the gastrointestinal tract. It may be a condition that occurs on an ad hoc basis in your body. In this case, it would be considered gastroenteritis caused by a viral or bacterial body. Gastritis also can develop into a chronic condition. If it is caused by a pathological agent, it will be observed swelling of the stomach wall. Thus, it is a stomach extension that can be prolonged over time.

When it occurs in an individual, it causes several symptoms to appear. The main one is swelling, and it is from this that almost all other symptoms arise. Among the latter, it can be cited the pains as well as the discomfort in the stomach. It must be understood that these types of pains are usually equated to excruciating burns. Indigestion, lack of appetite, increased stomach acidity, nausea, and vomiting are other severe symptoms of gastritis. It is also not uncommon to encounter patients with dark stool or diarrhea due to this autoimmune condition.

From the information put forward above, it is clear that gastritis is quite capable of causing serious damage to the human body when not treated properly. Therefore, it increases the chances of the patient developing stomach cancer. It is also capable of turning into a more severe form of gastritis. The latter is called erosive gastritis. It is known to completely wear away the gastric lining of the stomach.


Scientific research has provided insight into how gastritis works. These experiments have also offered the doctor the chance to discover all the existing forms of this condition.

Thus, the most well-known variant of gastritis is acute gastritis. This one is known to occur promptly. The direct cause of such a condition lies in the use of non-steroidal anti-inflammatory drugs. This causes the body to inhibit the enzyme that synthesizes eicosanoids in the stomach area. This results in the formation of a good number of gastric ulcers. In addition, you need to understand that physiological stress caused by hypoxia or other trauma can cause acute gastritis.

The second most well-known form of this condition has been given the name chronic gastritis. It is known to occur slowly over the long term. Certain diseases and autoimmune disorders are the main causes of chronic gastritis. These immune deficiencies are characterized by creating proteins and antibodies that perceive the stomach as a foreign body to the body. Since their role is to protect the body against external threats, they begin to damage its lining. Many experiments have shown that autoimmune gastritis occurs in most cases in patients with Hashimoto’s disease. People with type 1 diabetes and certain vitamin B12 deficiencies are also prone to this condition. It should be added that this form of gastritis is known to penetrate bile in the stomach. This due to connective tissue disorders and other liver insufficiencies. Advancing age is also a participating factor in the onset of chronic gastritis. This is quite normal since, with time, the stomach lining becomes increasingly thin.


At its core, the human body is made up of endocannabinoid receptors. This has allowed researchers to deduce that the body synthesizes even some cannabinoids. The receptors involved are distributed throughout the body’s organs and nervous tissue. In addition, many of the functions of the endocannabinoid system are directly related to the stomach. This is why treating gastritis with CBD consumption is a completely safe and effective option.

Furthermore, CBD provides the same benefits to people suffering from this condition as conventional medications. However, it does not cause the unwanted side effects that conventional treatments do. Thus, CBD can be used for:

  • Reduce the symptoms of gastritis

In reality, cannabis has virtues that allow its consumer to reduce nausea and vomiting. Indeed, the THC contained in CBD allows this product to directly affect the areas of the brain in charge of triggering the release of stomach contents.

  • Reduce inflammation

Above, it has been said that inflammation of the intestinal wall is the main symptom of gastritis. Since CBD has anti-inflammatory properties, it is very effective in this particular case.

Is it possible to self-prescribe CBD for gastritis?

CBD is certainly excellent, but it is not safe to self-prescribe it. So, avoid consuming it without a specific prescription and the approval of your doctor. Instead, it is advisable to approach a doctor to evaluate and determine the proper dose of CBD.

Does CBD completely cure gastritis?

CBD primarily treats the symptoms of gastritis. It reduces them until they disappear. However, when taken regularly, it is not unthinkable that it may not completely cure this ailment.

What are the different potential side effects of CBD?

CBD is a natural product that is considered safe and consumable without negative health implications. The World Health Organization (WHO) has officially stated that CBD is neither harmful nor addictive.

When applied topically or taken orally, its effects are therapeutic and recommended for people wishing to relax, calm anxiety, or treat symptoms of illness.

There are some potential side effects to keep in mind when using this substance, however, the majority of which are mild. Each individual reacts differently to CBD and may develop a different reaction, positive or negative, depending on their body.

Among the most common side effects, CBD can cause nausea, drowsiness, dry mouth, gastrointestinal issues and a few other discomforts that fade with time and use.

In this article, let’s look in detail at the potential side effects of CBD on the body. Keep in mind that these side effects are not systematic and do not last over time.

What is cannabidiol (CBD)

Let’s briefly review what CBD is. This is important to understand how it works in the body and its effects. CBD, short for cannabidiol, is a compound from the hemp plant that has become very popular since 2014 according to internet research on the molecule.

CBD is thus one of many chemical compounds found in the cannabis plant, also known as cannabis sativa. The two main compounds found in cannabis are the well-known THC, or Tetrahydrocannabinol, and CBD, which has made a name for itself in recent years. Although they come from the same plant, THC and CBD are very different from each other. Let’s take a look at what sets them apart.


In fact, THC is the psychoactive molecule that makes you “high” in cannabis. It is prohibited for consumption in France. CBD is classified as a non-harmful and non-psychoactive molecule because it contains less than 0.2% THC in its composition. Cannabis plants such as marijuana are grown to have high levels of THC and are illegal to grow, market and consume in France.

CBD is considered non-harmful and very good for your health. In fact, its therapeutic properties are useful in the natural treatment of symptoms of diseases with limited treatment resources such as Parkinson’s disease , Alzheimer’s , epilepsy , fibromyalgia etc.

The side effects of THC are obvious. They range from the euphoric effect for which it is best known, to much more limiting effects such as depression, anxiety, fear of death, paranoia, loss of control, hallucination etc.

The side effects of CBD are the opposite of THC. This is because CBD does not get stoned, which reduces the discomfort that CBD can potentially cause on its consumer. Let’s look at its side effects in detail.

The potential side effects of CBD

The most commonly reported side effects of CBD users include drowsiness, gastrointestinal problems, dry mouth, reduced appetite, nausea, results of interaction with other medications and fatigue. They are rare, mild and usually over a very short period of time.

Let’s look at them in detail below.


One of the common side effects when using CBD is drowsiness and sedation. Indeed, CBD is well known to be a product to take before going to bed as it is relaxing and can help with insomnia. This side effect is therefore considered an advantage for people who have difficulty sleeping. However, it is important to keep in mind that not all CBDs make you want to sleep. Some are very suitable for consumption in the morning. Read the directions on your products.

Gastro-Intestinal Problems

Some people may experience diarrhea or liver problems when using CBD. This depends a lot on the consumer and their medical history. This side effect is rare and only appears on a small portion of people who use CBD. If it appears, it must nevertheless be taken very seriously. If you have intestinal problems, do not hesitate to ask your doctor for advice before consuming CBD. He or she can help you set a dosage to avoid having these discomforts.

Dry Mouth

CBD can potentially make the mouth and eyes very dry. While this side effect is more likely to occur with THC, it can also occur with CBD as well. This dry mouth is caused by CBD’s action on the endocannabinoid receptors present in the salivary glands. You can calm this sensation quickly with a glass of water.

Appetite reduction

CBD is known to affect the level of serotonin that the body produces, and thus the cravings that it causes. By increasing serotonin levels naturally, the effect of CBD kind of replaces the pleasure effect that food might produce. We cannot yet say that CBD acts strongly on the appetite however, it is undeniable that it causes in some consumers this sensation of appetite reduction.


Fatigue is a very rare side effect of CBD that is usually seen by people with chronic fatigue syndrome. Therefore, it is possible that people predisposed to having fatigue may feel very tired when taking CBD.

Interaction with other medications

CBD could interfere with other medications you are taking. It’s important to talk to your doctor about whether CBD could affect your existing prescriptions. Check out our article: CBD and taking medication: Possible?


While CBD is known for its anti-inflammatory effects that are very good for nausea, gastritis, and other inflammation in the stomach, in some cases CBD-derived products can cause transient nausea. This effect depends greatly on the intestinal sensitivity and the physical and emotional state of the CBD user, as well as the quantity ingested. This side effect is rare and often due to a combination of factors including CBD intake, but is never due to CBD consumption alone.

How to prevent CBD side effects

First, don’t hesitate to talk to your doctor about these discomforts. If you already have prescriptions, your doctor will be able to advise you on the ideal dosage of CBD for your situation.

If you are a new user, we recommend starting your use with light doses at first. A few drops of oil under the tongue 3 times a week to start, then you can increase this dosage little by little, until you find your ideal dosage depending on the effects you are looking for.

Finally, it is highly recommended to consume quality products, purchased from trusted suppliers. Suppliers must deliver you the exact composition of the products, their source as well as their effects in the product sheet of the same. Poor quality products increase the risk of side effects or even create more for you.

If you experience persistent side effects from CBD, talk to your doctor.
