Gastritis (Stomach Pain)

What Is It and How to Find Relief

Many have suffered from gastritis at some point in their lives. You ate something that disagreed with your stomach, and it burned. You took too many aspirin on an empty stomach for a week when you were recovering from breaking your ankle, and your stomach started to ache. You consumed too much alcohol during a weekend wedding celebration, and now your stomach hurts. What are the numerous causes of gastritis, and what can be done to recover from it? 

All About Gastritis 

Gastritis refers to inflammation of the stomach lining, which is composed of three main layers: the epithelium, containing mucus-secreting cells that produce protective alkaline mucus; the lamina propria, a connective tissue layer with blood vessels and immune cells; and the muscularis mucosae, a thin band of smooth muscle that moves glandular secretions. The stomach lining also contains gastric glands with parietal cells that secrete hydrochloric acid, chief cells that release digestive enzymes such as pepsinogen, and mucous cells that produce mucus. All these work together to protect the stomach from self-digestion, inflammation, dysbiosis, and injury, while also aiding in the breakdown and preparation of food for absorption in the intestines.1 2 3  

The stomach mucosa is composed of proteins, amino acids, minerals, lipids, and protective compounds that form a resilient barrier against acid, enzymes, and pathogens. Structural proteins such as collagen and elastin, made from amino acids like glycine, proline, and hydroxyproline, along with vitamin C, vitamin A, and minerals such as sulfur, zinc, manganese, magnesium, and copper, provide stomach submucosa strength and health. Mucins, large glycoproteins rich in carbohydrates, create the protective stomach mucus layer. Glutathione and sulfhydryl groups protect the stomach mucosal barrier from oxidative stress. These components help the stomach mucosa remain strong, self-repairing, and able to withstand the rigors of digestion.4 5 6 7 8  

Growth factors such as epidermal growth factor (EGF) and transforming growth factor (TGF) support stomach lining healing, while hormones such as gastrin and somatostatin regulate acid secretion and mucosal growth. Prostaglandin E2 (PGE2), produced by cyclooxygenase (COX) enzymes, stimulates mucus and bicarbonate secretion, increases mucosal blood flow, and reduces gastric acid output, all of which strengthens the mucosal barrier. Nitric oxide, produced by nitric oxide synthase, promotes vasodilation in the stomach’s microcirculation, ensuring adequate oxygen and nutrient delivery, and supporting healthy mucus secretion.9 [10 . https://pmc.ncbi.nlm.nih.gov/articles/PMC4532093/] 10  

Gastritis Causes Include:11 12 13 14 15 16 17 18  19 20 21  

  • Anticoagulant use (abigatran, apixaban, dabigatran, rivaroxaban, and warfarin) 
  • Caffeine ingestion 
  • Carrageenan 
  • Cirrhosis and liver failure (portal vein hypertension) 
  • Critical illness or shock (stress-induced gastritis likely caused by decreased blood flow to the stomach) 
  • Cysts 
  • Cytostatic medications (for example, mycophenolate mofetil) 
  • Endoscope biopsy 
  • Excessive alcohol consumption 
  • Foodborne illness and poisoning 
  • Food allergies (eosinophilic gastritis) 
  • Immune checkpoint inhibitor medications (for example, anti-PD1 medications like cemplimab, anti-PD-L1 medications like avelumab, and anti-CTLA-4 medications like imjudo) 
  • Infections (bacterial [H. pylori], viral, fungal, and parasitical) 
  • Iron supplementation (iron bisglycinate might be less irritating)  
  • Glucocorticosteroid use (might weaken stomach immunity, causing or worsening dysbiosis, and inhibits prostaglandin E2) 
  • Kidney disease and failure 
  • Microbial die-off 
  • Non-steroidal anti-inflammatory COX2 inhibitors (aspirin, curcumin, ibuprofen, meadowsweet, naproxen sodium, turmeric, white willow bark), herbs, supplements, or medications, especially when taken repeatedly on an empty stomach 
  • Radiation (cancer therapy, excessive exposure) 
  • Smoking 
  • Stomach surgery 
  • Traumatic injury to the stomach 
  • Tumors 

Gastritis Symptoms Are:22 23 24 25 26  

  • Abdominal pain (worsens usually immediately during/after eating) 
  • Anxiety 
  • Burning feeling within your stomach (underneath the bottom of your left rib cage, worsens usually immediately during/after eating) 
  • Cibophobia (fear of eating) 
  • Depression 
  • Dyspepsia (indigestion) 
  • Early satiety (feeling full early when eating) 
  • Frequent belching 
  • Frequent hiccups 
  • Gnawing feeling within your stomach (underneath the bottom of your left rib cage, worsens usually immediately during/after eating) 
  • Loss of appetite 
  • Nausea 
  • Pernicious anemia, which is known as a form of anemia caused by a vitamin B12 deficiency 
  • Pressure feeling within your stomach (underneath the bottom of your left rib cage, worsens usually immediately during/after eating) 
  • Sore feeling within your stomach (underneath the bottom of your left rib cage, worsens usually immediately during/after eating) 
  • Stomach pain (underneath the bottom of your left rib cage, worsens usually immediately during/after eating) 
  • Weight loss from loss of appetite 
  • Upper abdominal bloating 
  • Upper back deferred pain 
  • Vomiting (if your vomit is full or red blood or black blood that looks like coffee grounds and smells like, iron go to the emergency room immediately) 

Diagnostic tests useful in the diagnosis of gastritis are upper abdominal X-rays, upper abdominal CT scan, endoscopy, total blood cell count testing, vitamin B12 blood serum and methylmalonic acid testing to determine pernicious anemia, H. pylori colonization tests, liver, kidney, gallbladder, or pancreatic function tests, stool sample (check for bleeding and dysbiosis), and stomach biopsy.27 28 29  

What to Do to Relieve Your Gastritis 

  • Avoid taking bismuth, iron, and zinc on an empty stomach. If you have to ingest iron, take iron bisglycinate in divided doses with food throughout the day. 
  • Consume multiple small meals daily, four to five, to see if your symptoms improve. Food buffers stomach acid, so eating more frequently might help improve symptoms.  
  • Ingest beets or beet juice for dietary sources of nitrates, which increases the production of nitric oxide within the body when consumed.  
  • Look into using low-level laser therapy (LLLT) on your stomach a couple of times weekly to accelerate healing.30  
  • A low vitamin D blood level is associated with the development or worsening of gastritis symptoms.31  
  • Proper sunlight exposure can help improve symptoms. Sunlight exposure increases nitric oxide expression, especially when your stomach is exposed directly to sunlight.  
  • Eating spicy food might irritate the lining of your stomach, but it can also stimulate gastric mucosal production and blood flow to your stomach and can relieve pain and inflammation. Try spicy foods and see if they help or make the gastritis worse!  
  • Supplement with L-glutamine if you can tolerate it or consume bone broth and/or cabbage juice on an empty stomach (do not consume bone broth or cabbage if you have H2S dysbiosis or bone broth if you have histamine intolerance or MCAS).  
  • Talk with your doctor about switching to different medications if they are causing or worsening your gastritis, and if you must take them, discuss consuming them with food for extra protection.  
  • Taking basic (pH) minerals like calcium, magnesium, and potassium might irritate the lining of your stomach. You might have to take them in smaller doses throughout the day, sometimes with food, even if they neutralize stomach acid, which may worsen dysbiosis.  
  • Ten to twenty minutes of daily infrared and red-light LED exposure on your stomach can increase blood flow, stimulate collagen production, and accelerate healing.32   
  • Try to get seven to eight hours of sleep nightly. Proper sleep hygiene can help improve your symptoms.  
  • Quit consuming alcohol, caffeine, and smoking if you are.  

Herbs for Gastritis – Start With the Lowest Recommended Dosages With Food to Determine Tolerance 

  • Now slippery elm extract – mix one teaspoon well with eight ounces of water and let sit for a few minutes before consuming ten minutes before a meal once or twice daily. Do not supplement if you cannot tolerate oxalate ingestion and suffer from poor oxalate metabolism. 

Supplements For Gastritis – Start With the Lowest Recommended Dosages With Food to Determine Tolerance 

  • N-acetyl glucosamine – Start with one capsule with a meal daily, and increase to two capsules with a meal, divided if needed. Use caution if you have Candida dysbiosis. 
  • Quercetin – Quercetin may be a weak proton pump inhibitor, which could reduce stomach acid production and hinder digestion. If you can tolerate it, take it on an empty stomach away from food. I would caution against using quercetin in anyone with catechol-O-methyltransferase (COMT) enzyme deficiency, which is likely due to a genetic polymorphism and overmethylation. Supplementation of quercetin in people with COMT enzyme deficiency may cause or increase the frequency of certain symptoms, including anxiety, brain fog, mania, schizophrenia, delusions of grandeur, bipolar disorder (mania), and estrogen dominance. Finally, quercetin has been shown to possibly cause or worsen Hashimoto’s thyroiditis and hypothyroidism by interfering with thyroid cell growth, reducing iodide uptake, and decreasing the expression of the thyrotropin receptor, thyroid peroxidase, and the thyroglobulin gene. Take one capsule with food to see how you tolerate it and you can increase to two capsules daily in divided doses depending on tolerance.
