What Causes Gastritis? Causes, Symptoms, and Remedies

Gastritis can significantly impact digestive health and overall well-being, and understanding what causes gastritis is crucial for effective management and prevention. 

Explore common gastritis symptoms and discover natural remedies to soothe an irritated stomach and restore digestive functions.

What is gastritis?

Gastritis occurs when the stomach’s mucosal lining, which is a specialized layer that protects the stomach from being broken down by its own acidity, becomes inflamed. 

When this lining becomes damaged or irritated, it can expose the stomach wall to stomach acid and digestive enzymes, leading to pain, nausea, and indigestion.

Over time, this inflammation can lead to erosive gastritis, where the protective lining wears away, increasing the risk of intestinal bleeding and ulcers.

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) reports that gastritis is a common condition impacting up to 35 percent of people at some point in their lives.

Gastritis can present as either acute or chronic. Acute gastritis occurs suddenly, often triggered by irritants such as excessive alcohol consumption or certain medications.

In contrast, chronic gastritis develops gradually due to long-term factors such as diet, stress, and bacterial infections.

Gastritis symptoms

Gastritis symptoms can vary in severity but often include noticeable digestive discomfort.

Common symptoms of gastritis include:

• Indigestion 

• Vomiting, especially yellow or green fluid 

• Nausea 

• Low appetite 

• Abdominal pain, especially in the upper portion

• A sensation of burning, especially at night and in between meals

These symptoms can significantly disrupt daily life and increase the risk of further complications such as stomach ulcers and even stomach cancer if left unaddressed. 

What causes gastritis? 

One of the most common causes of gastritis is the bacterium Helicobacter pylori (H. pylori). When present in large amounts, these microbes release compounds that can damage the stomach lining, lower stomach acidity, and hinder stomach acid and intrinsic factor production.

“When the stomach lining is compromised, it can trigger a cascade of digestive issues,” explains Dr. Berg. “Your defenses against harmful bacteria weaken, and your ability to absorb essential nutrients, such as vitamin B12, becomes impaired.”

Additional triggers of gastritis include poor diet, excessive consumption of alcohol or coffee, chronic stress, and the overuse of medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) and proton pump inhibitors (PPIs).

Bile reflux, characterized by bile backing up into the stomach due to blocked bile ducts or other digestive issues, can also lead to gastritis symptoms. 

Autoimmune gastritis, though rare, occurs when the immune system mistakenly targets the stomach's acid-producing cells, leading to persistent inflammation.

Managing gastritis naturally

There are several natural ways to help manage gastritis symptoms naturally and promote healing of the stomach lining.

Here are six natural ways to help manage gastritis.

1. Healthy keto and intermittent fasting

One of the best ways to support a healthy digestive system is to cultivate better eating habits.

Adopting a Healthy Keto® diet and incorporating intermittent fasting can work synergistically to help stabilize blood sugar levels, support gut health, and reduce inflammation.

The Healthy Keto diet emphasizes nutrient-dense, low-glycemic, and anti-inflammatory foods. This includes organic, non-genetically modified (GMO) produce, healthy fats, pasture-raised meats and dairy, wild-caught fatty fish, and game meat. 

These foods create an optimal environment for soothing and healing the stomach lining and reducing irritation while fortifying the stomach's defenses against irritants like H. pylori.

Intermittent fasting, on the other hand, offers the digestive system regular breaks, allowing it to rest and repair tissue damage by promoting the regenerative state of autophagy.

Together, Healthy Keto and intermittent fasting support optimal digestive health by reducing stress on the stomach, promoting healing, and enhancing the body's natural ability to fight inflammation and microbial infections. 

2. Reduce stress

Chronic stress triggers the release of cortisol, the body’s primary stress hormone that can worsen inflammation and damage the stomach lining over time.

Engaging in stress-relieving activities such as stretching and deep breathing exercises can help combat everyday stressors and lower cortisol levels. 

Furthermore, regular physical activity helps regulate mood-enhancing hormones and fosters relaxation, which has been shown to reduce cortisol levels effectively.

3. Prioritize sleep

Getting enough sleep is essential for strengthening the immune system, reducing inflammation, and repairing tissues. To promote digestive health, aim for 7 to 9 hours of uninterrupted sleep each night.

To improve sleep quality, eliminate artificial light exposure before bed, especially from screens that emit blue light. In addition, it’s recommended to avoid eating a few hours before bedtime to prevent blood sugar fluctuations that can disrupt sleep.

4. Promote a diverse gut microflora 

Probiotics are beneficial bacteria that support a balanced and diverse gut flora, which is critical for digestive health and helps inhibit harmful bacteria such as H. pylori, a major gastritis trigger. 

Incorporating probiotic-rich fermented foods such as kefir, yogurt, sauerkraut, and kimchi, along with nutrient-rich prebiotic foods such as cabbage, broccoli sprouts, and lightly cooked greens, can support a balanced gut microbiome without exacerbating inflammation.

Additionally, it’s crucial to avoid processed and sugary foods, which can trigger and exacerbate inflammation and disrupt the growth of beneficial gut microbes.

5. Vitamin D and zinc carnosine

Vitamin D is vital for enhancing immune functions and maintaining optimal vitamin D3 K2 benefits is essential to lower the risk of microbial infections and reduce inflammation. 

In addition to vitamin D, zinc carnosine has been recognized for its ability to repair the stomach lining and combat chronic inflammation.

Research published in Nutrients showcases zinc carnosine’s anti-inflammatory and antioxidant properties, which help promote gastric healing. Zinc carnosine plays a key role in overall gastric health by stabilizing protective epithelial cells and reducing oxidative stress in the stomach lining.

Moreover, zinc carnosine supports the regeneration of the stomach's mucosal barrier and enhances the healing process of gastric ulcers and inflammation, making it a valuable component in managing digestive issues such as gastritis.

6. Mastic gum

Mastic gum is a natural resin known for its antimicrobial properties against H. pylori and soothing effects on digestion.  

Over time, mastic gum may help reduce inflammation and alleviate gastritis symptoms, especially when combined with other gut-friendly lifestyle changes.

When to talk to your doctor 

Information related to gastritis should be discussed with a healthcare provider to determine suitable management approaches based on individual health needs.

While natural remedies can be effective, certain cases require immediate medical attention, especially if you experience severe abdominal pain, persistent vomiting, or blood in your vomit or stool. 

Conditions such as autoimmune gastritis and potential complications related to gastrointestinal and liver disease require professional medical evaluation.

As with any medical condition, it's important to consult your healthcare provider before making significant dietary changes or adding supplements, ensuring personalized guidance tailored to your needs.

Key takeaways

Understanding what causes gastritis is essential for effective management. 

While a Helicobacter pylori infection is a common gastritis trigger, lifestyle factors, including a poor diet, alcohol consumption, and certain medications, can also irritate or inflame the stomach lining. 

Restoring digestive health and promoting healing can be achieved by adopting Healthy Keto, incorporating probiotic-rich foods, supplementing with zinc carnosine and vitamin D3, and practicing intermittent fasting.
