How Cannabis May Help Treat Gastritis

Cannabis can be an effective, natural, and safe treatment against gastritis. The herb contains cannabinoids, that bind to CB1 receptors within the gut, resulting in tissue repair.

Modern science is unveiling how cannabis can work within the human body in a very specific way in order to successfully treat and possibly even cure a wide variety of illnesses, ailments, and conditions. One condition, that the herb seems to help treat is gastritis, a group of symptoms, that are all caused by inflammation of the gut.


Gastritis is characterised by inflammation occurring within the gut, and can manifest in multiple forms. The inflammation at the root of the condition is most commonly caused by a strain of bacteria known as Helicobacter pylori, which is one of the most common bacterial infections. However, only a select amount of people who become infected by the bacteria suffer with symptoms of gastritis. This could be because of numerous factors, including genetics, lifestyle, and environmental factors.

When it comes to lifestyle choices, gastritis can spring up after the use of alcohol, spicy foods, anti-inflammatory drugs, autoimmune issues, radiation therapy, and Crohn’s disease.

These factors can lead to inflammation of the gut lining, leading to inflammation of the mucosa. The condition can eventually damage this protective layer, leading to stomach acid damaging the stomach lining.


Gastritis, that appears suddenly is known as acute gastritis and can be directly linked to the use of non-steroidal anti-inflammatory drugs (NSAIDS). This is due to inhibition of an enzyme, that is responsible for synthesis of eicosanoids within the stomach, which can lead to the formation of stomach ulcers. Drugs such as aspirin can also lead to reduced production of prostaglandin, which actively helps to protect the stomach. Physiological stress from hypoxia and trauma can also lead to acute gastritis.

Gastritis, that appears slowly over a long period of time, is known as chronic gastritis. This can be caused by autoimmune disorders, where the body creates proteins and antibodies, that perceive the stomach as a foreign threat and begin to attack and deteriorate the stomach lining. Autoimmune gastritis is more common in patients experiencing Hashimoto’s disease, type 1 diabetes, and vitamin B12 deficiency.

Chronic gastritis can also be caused by bile making its way into the stomach, connective tissue disorders, and liver or kidney failure.

Old age is also a contributing factors, considering, that the stomach lining tends to thin with age, and the older population is more likely to experience Helicobacter pylori infections than the younger population.


Gastritis can lead to an array of uncomfortable symptoms, which can in some cases eventually lead to stomach ulcers and even an increased risk of stomach cancer. One major symptom of the condition is a burning ache or pain, that manifests in the stomach region and within the upper abdomen. Other symptoms include nausea, vomiting, bloating, belching, indigestion, and loss of appetite.


Avoiding certain foods, such as acidic fruits and high-fat food may help with the condition, along with halting lifestyle habits such as smoking, consuming caffeine, and drinking excessive amounts of alcohol.

Certain antibiotics may also be used in order to target Helicobacter pylori bacteria. However, such medications may actually result in side effects, that are similar to the symptoms of gastritis itself, such as nausea, vomiting, loss of appetite, and abdominal pain.

Cannabis is a safe and natural medicine, that acts as an excellent option for some people that are dealing with the condition. The herb can offer some of the benefits of conventional medicines used for the condition, yet without many of the damaging and uncomfortable side effects, that can reduce the patient’s quality of life.

Cannabis can act to reduce some of the symptoms caused by the condition, and may actually act at a deeper level to quell the inflammation at the root cause of gastritis.


Cannabis is well known to assist in nausea and vomiting, two symptoms of gastritis. THC, a psychoactive cannabinoid within the cannabis plant, has been prescribed since the 1980s for the treatment of nausea, and is often employed to combat it after bouts of chemotherapy. Its effectiveness is believed to be linked to how the cannabinoids effect centres within the brain, that control both nausea and vomiting.

Loss of appetite is another symptom of gastritis, and one, that cannabis can definitely assist with. The plant is associated with the famous stereotype of inducing the “munchies”, a ravenous appetite, that can occur after ingesting THC, resulting in the raiding of many fridges.

Research has shown that gastritis is associated with mood disorders, such as anxiety, panic attacks and depression. Cannabis is commonly prescribed for these mental conditions and may be of great assistance to gastritis patients who are suffering from them.


As we have discussed, the primary cause of gastritis is inflammation of the gut lining. Cannabis produces numerous cannabinoids with potent and proven anti-inflammatory properties, such as CBD.

What’s more, a 2005 study conducted at the University of Bath and Bristol in the United Kingdom, showed that cannabis is effective in cases of inflammatory bowel disease and gastritis. The researches explained that cannabis influenced cannabinoid receptors within the gut and brain, resulting in effective treatment.

Cannabinoid receptors can be found all throughout the body, and make up what is known as the endocannabinoid system. These receptors are activated by numerous cannabinoids within the cannabis plant. The endocannabinoid system is partly made up of CB1 receptors, which can be found within the brain and the lining of the gut. These receptors are reported to help repair the gut lining when it becomes damaged.

During the study, researchers purposely damaged gut tissue, resulting in inflammation. Synthetic cannabinoids were then administered to the tissue, resulting in the healing process. It is believed, that cannabinoids created within the body, or endocannabinoids, are released from endothelial cells of a healthy gut, which go on to bind to CB1 receptors and assist in the repair process when damage occurs. When patients use medical cannabis, external cannabinoids may help to fulfil the same purpose.

Cannabis has been shown to be effective at helping to repair the gut when it comes to gastritis, activating CB1 receptors within the region.

Acute Gastritis

Updated on May 21, 2020. Medical content reviewed by Dr. Joseph Rosado, MD, M.B.A, Chief Medical Officer

For many years, healthcare specialists have been treating gastritis with medicines, such as protein pump inhibitors and H2 antagonists, to reduce the amount of the acid the stomach produces. However, some people experience side effects from these medicines.

Fortunately, cannabis has been used to help treat medication side effects as well as treat gastritis symptoms. Researchers are studying how well medical marijuana treatment for acute gastritis works for easing pain, inflammation and other symptoms of the condition.

How/Why Marijuana Can Be an Effective Treatment for Acute Gastritis

People have cannabinoid receptors both in their gut and brain. It’s thought they’re an essential part of the healing process of a gut that’s damaged. Studies show cannabinoids heal stomach inflammation and slow gut motility, which reduces muscle cramp pain that leads to diarrhea.

Medical marijuana for acute gastritis has been shown to relieve acute gastritis-related pain in patients. Medical weed improves the appetite in patients and eases their pains, aches and stress associated with their condition.

Cannabis also doesn’t pose a risk of addiction like other conventional medications. However, depending on dosage and strain, some patients experience slowed reaction times, paranoia, dry mouth, red eyes, increased heart rate and drowsiness as some of the side effects of marijuana.

What Side Effects and Symptoms of Acute Gastritis Can Medical Marijuana Treat?

Common acute gastritis symptoms that cannabis for acute gastritis treatment helps with include:

  • Nausea
  • Pain
  • Vomiting
  • Insomnia
  • Lack of appetite
  • Weight loss
  • Anxiety
  • Depression

Some ways it helps these and other symptoms include:

  1. Nausea: Inflammation in the gut in acute gastritis is what causes nausea, and this prevents normal digestive system functioning. Small doses of medical weed used regularly can help eliminate nausea.
  2. Vomiting: The feeling of nausea is what usually causes the vomiting. However, vomiting may also occur due to indigestion. You can use cannabis for acute gastritis to stop nausea and help improve digestion and other bodily functions — which can prevent vomiting.
  3. Weight Loss:Weight loss occurs quickly in acute gastritis because the person affected isn’t able to eat properly due to their nausea. Even when they’re able to consume some food, they end up vomiting it out. So, when you use medical pot, it helps nausea and vomiting, which, in turn, helps prevent weight loss. Also, since marijuana is associated with “the munchies” and often causes people to eat more, it helps with weight gain.
  4. Abdominal pain: Medical cannabis is an effective pain reliever and often used in various disorders where chronic pain is a symptom. Therefore, doctors also recommend it for the pain caused by acute gastritis. The herb interrupts the pain pathway, relieving the pain sensation.
  5. Diarrhea: Diarrhea is another common issue in those struggling with acute gastritis. Consuming foods can lead to ingestion of particular microorganisms that may bring on bouts of diarrhea. Using marijuana for acute gastritis acts like a bactericidal drug, killing the numerous diarrhea-causing microorganisms.

Using small doses of medical cannabis regularly can help eliminate acute gastritis. However, you need to choose the right strains to relieve your symptoms optimally and keep in mind that medical marijuana is not without side effects if it’s misused. If you dose incorrectly, you could develop certain side effects, as described above.

What Is Acute Gastritis?

Acute gastritis is where you experience sudden swelling or inflammation in your stomach lining. It can cause nagging, severe pain. This pain, however, is temporary and typically only lasts for brief periods of time. Gastritis is acute when it’s short-lived, but it can become chronic.

Gastritis is not the same as gastroenteritis. Gastroenteritis affects both your intestines and stomach, causing symptoms like nausea, vomiting or diarrhea. Gastritis affects your stomach only and could cause symptoms of nausea and vomiting.

Causes of Acute Gastritis

Acute gastritis can occur when your stomach lining is weak or damaged. When you have a weak or damaged stomach lining, it allows your digestive acids to aggravate your stomach.

Acute gastritis appears suddenly and has several causes, including:

  • Viruses
  • Bacteria (i.e., H. pylori)
  • Stress
  • Injury

H. pylori bacteria may infect your stomach and lead to peptic ulcers. While it’s not known how H. pylori spreads, it may lead to loss of appetite, stomach inflammation, abdominal pain, nausea and more.

Or, gastritis can occur by ingesting irritants like:

  • Steroids
  • NSAIDs
  • Alcohol
  • Spicy food

Other less common causes of acute gastritis include:

  • Extreme stress
  • Viral infections
  • Cocaine use
  • Bile reflux
  • Autoimmune disorders
  • Surgery
  • Digestive disorders and diseases like Crohn’s disease
  • Kidney failure
  • Ingesting poison and other corrosive substances
  • Being on a respirator or breathing machine
  • Systemic stress

Symptoms of Acute Gastritis

Individuals may experience symptoms with gastritis uniquely. Some may have no symptoms at all. The most common acute gastritis symptoms are:

  • Abdominal pain
  • Abdominal bloating
  • Indigestion
  • Nausea
  • Vomiting
  • Recurrent upset stomach
  • Hiccups
  • Gnawing or burning feeling in your stomach at night or between meals
  • Loss of appetite
  • Tarry, black stools
  • Vomiting a coffee ground-like substance or blood

Physical Effects of Acute Gastritis

Some physical effects of acute gastritis often include:

  1. Atrophic gastritis: Atrophic gastritis occurs when chronic stomach lining inflammation causes the loss of your glands or stomach lining. Chronic gastritis may lead to atrophic gastritis.
  2. Pernicious anemia and vitamin B12 deficiency: Those with autoimmune atrophic gastritis don’t produce sufficient intrinsic factor. This is a protein your stomach makes, and it helps your intestines absorb vitamin B12. Your body requires vitamin B12 to produce nerve cells and red blood cells. When you have poor vitamin B12 absorption, it can result in a type of anemia.
  3. Peptic ulcers: These are sores that involve your duodenum (first part of your small intestine) or stomach lining. H. pylori gastritis and NSAID use increase your risk of developing peptic ulcers.
  4. Anemia: Chronic stomach bleeding can result from erosive gastritis, and the loss of blood can cause anemia. Anemia is a disorder where you have smaller-than-normal or fewer red blood cells, so the rest of your body’s cells can’t obtain enough oxygen. Hemoglobin is in your red blood cells. Hemoglobin is an iron-rich protein that gives your blood its red color and helps your red blood cells carry oxygen to your body tissue from the lungs. Some research suggests autoimmune atrophic gastritis and H. pylori gastritis may interfere in how your body absorbs iron from food, which can lead to anemia, according to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
  5. Growths in the stomach lining: When you have chronic gastritis, it can increase your risk of developing noncancerous (benign) and cancerous (malignant) growths in the lining of your stomach. Chronic H. pylori gastritis increases your risk of developing gastric mucosa-associated lymphoid tissue (MALT) lymphoma — a type of cancer.

In many instances, acute gastritis doesn’t lead to many complications. However, it can, in rare cases, cause life-threatening, severe bleeding.

Mental Effects of Acute Gastritis

Gastritis patients have a higher risk for anxiety and mood disorders, according to the results of a study published in the Journal of Psychiatric Research. After accounting for gender, age and socioeconomic status in the study, the researchers found that those with gastritis had a higher risk than the general population in the previous 12 months, to have had any:

  • Anxiety disorder
  • Social phobia
  • Panic attacks
  • Major depression
  • Mood disorder

There was a stronger link between anxiety and mood disorder and gastritis in men than in women, even though it wasn’t a significant difference.

Acute Gastritis Statistics

Past statistics show the gastritis prevalence rate of gastritis was around 2.7 million individuals or one in 100 (0.99%) in the U.S.

Acute Gastritis History

Georg Ernst Stahl, a German physician, first used the term “gastritis” in 1728. Giovanni Battista Morgagni, an Italian anatomical pathologist, further described the gastric inflammation characteristics. He described the characteristics of ulcerative or erosive gastritis.

Between the years 1808 and 1831, François-Joseph-Victor Broussais, a French physician, collected data from an autopsy of deceased French soldiers. He noted chronic gastritis to be “Gastritide” and mistakenly believed gastritis was the cause of typhoid fever, ascites, and meningitis.

Wilson Fox and Charles Handfield described microscopic changes to the stomach’s inner lining with gastritis in 1854, which existed in segmental and diffuse forms. In 1859, William Brinton, a British physician, first described chronic, acute and subacute gastritis.

Current Treatments Available for Acute Gastritis and Their Side Effects

Some acute gastritis cases disappear without requiring treatment, and consuming a bland diet can help with a speedier recovery. Acute gastritis patients tend to tolerate foods best that are:

  • Low in fat
  • Low in natural acids
  • High in fiber

Also, if you can tolerate it, physicians suggest adding lean meats like turkey or chicken breast to your diet.

Many individuals require treatment for acute gastritis, though. Both treatment and recovery times vary depending on what’s causing gastritis and its severity. For instance, H. pylori infections might require a couple of rounds of antibiotics. Other treatments may involve medications for reducing symptoms, like those that treat viruses.

Treatment options may include the following:

1. Home Remedies

Making some lifestyle changes could help reduce your symptoms of acute gastritis. Some lifestyle changes that could help are:

  • Avoiding fried, spicy and acidic foods
  • Limiting or avoiding alcohol
  • Reducing stress
  • Eating small, frequent meals
  • Avoiding medications, like aspirin and NSAIDs, that might aggravate your stomach lining

2. Medications

There are both over-the-counter and prescription medicines for gastritis. Often, your doctor will recommend a combination of drugs, including the following:


These include TUMS®, Pepto-Bismol or milk of magnesia. They work by neutralizing your stomach acid. Those with gastritis often try these to find relief. Some brands even use a combination of three basic salts: aluminum, calcium, and magnesium, along with bicarbonate ions or hydroxide to neutralize stomach acid.

There are various side effects that are possible when taking antacids, however, including the following:

  • Antacids might cause milk-alkali syndrome and dose-dependent rebound hyperacidity.
  • Antacids containing aluminum hydroxide could cause constipation, osteomalacia, aluminum-intoxication, and hypophosphatemia.
  • Antacids containing calcium carbonate may also cause constipation.
  • Antacids containing magnesium could cause a laxative effect, leading to diarrhea.

H2 Antagonists

H2 antagonists like cimetidine (Tagamet) and famotidine (Pepcid) reduce stomach acid production.

Side effects of H2 antagonists include:

  • Diarrhea
  • Constipation
  • Dry skin
  • Dry mouth
  • Difficulty sleeping
  • Ringing in the ears
  • Headaches
  • A runny nose

Proton Pump Inhibitors

These include esomeprazole (Nexium) and omeprazole (Prilosec), and they inhibit stomach acid production.

Side effects of proton pump inhibitors include:

  • Abdominal pain
  • Headache
  • Constipation
  • Diarrhea
  • Fever
  • Nausea
  • Vomiting
  • Flatulence

Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)

Some physicians may suggest NSAIDs for the treatment of acute gastritis in some patients.

Side effects of NSAIDs may include:

  • Stomach pain
  • Bleeding
  • Stomach ulcers
  • Liver problems
  • Kidney problems
  • Ear ringing
  • Dizziness
  • Headache

Current prescribed inflammatory medications for treating acute gastritis can pose long-term use problems.


Your doctor may prescribe you antibiotics if you have a bacterial infection, such as from H. pylori. Some antibiotics commonly used for treating H. pylori are tetracycline, amoxicillin, and clarithromycin. Your doctor may prescribe antibiotics in combination with an antacid, proton pump inhibitor or H2 antagonist.

Side effects of antibiotics include:

  • Headache
  • Nausea
  • Vomiting
  • Stomach pain
  • Diarrhea
  • Rash
  • Vaginal discharge or itching
  • Black, swollen or “hairy” tongue
  • Becoming antibiotic resistant

Your doctor might suggest you stop taking any corticosteroids or NSAIDS to see if your symptoms get better. Don’t stop taking any prescription drugs without consulting with your doctor first, though.

Recent Developments in Acute Gastritis

Some recent acute gastritis developments include new clinical trials and studies such as:

  1. A clinical trial for Teprenone (a gastric mucosal protective drug) safety and efficacy in acute gastritis patients.
  2. A study evaluating DA-5204 (a new formulation for the gastritis medication Stillen) safety and efficacy.

There have also been other trials and studies to show the safety and efficacy of certain medications and treatments for acute gastritis.

Medical marijuana for acute gastritis has been shown to relieve acute gastritis-related pain in patients as well as several other symptoms and side-effects
