Gastritis can cause bad breath; the reasons may include poor digestion and reduced gastric motility in patients after developing gastritis, or possibly due to infection with Helicobacter pylori. Besides gastritis, other stomach diseases can also cause bad breath, such as peptic ulcers, malignant gastric tumors, and erosive gastritis, among others. Apart from stomach diseases, diseases related to the liver, gallbladder, and oral diseases can also cause bad breath. Therefore, when patients experience bad breath, they should visit the department of stomatology to determine if there are any oral diseases, complete imaging examinations of the liver and gallbladder, and, if necessary, also complete gastroscopic examinations.

What can you eat with gastritis?

Gastritis is generally divided into two main categories: chronic non-atrophic gastritis and chronic atrophic gastritis. It is usually diagnosed by gastroscopy, and the treatment plan is determined based on the presence or absence of Helicobacter pylori infection. Also, it is necessary to develop good eating habits. It is important to eat on a regular schedule with controlled portions or small, frequent meals, and chew slowly and thoroughly. Try to avoid binge eating or extreme hunger or fullness.

Can gastritis be cured?

Gastritis can be cured, primarily through medication, such as protecting the gastric mucosa, inhibiting gastric acid secretion, and appropriately using antibiotics. If there is a Helicobacter pylori infection, specific treatment for Helicobacter pylori must be conducted. After the treatment of gastritis, it is crucial to pay attention to dietary adjustments. Irregular eating habits can lead to the recurrence of gastritis. Therefore, it is advisable to maintain a light diet, consume more vegetables and fruits, eat less spicy and irritating food, avoid strong tea, coffee, and hard liquor which can damage the gastric mucosa, and keep a relaxed mood, which also positively affects the treatment of stomach diseases.

What should you eat more of if you have gastritis?

Patients with gastritis should primarily consume a light and easily digestible diet. Firstly, porridge can be eaten, including millet porridge, Chinese yam porridge, coix seed porridge, and eel porridge. Secondly, soups such as chicken soup, pork rib soup, duck soup, and fish soup can be consumed. During the preparation of these soups, ingredients like Codonopsis, Astragalus, Poria, and coix seeds can be added, which are effective in strengthening the spleen, facilitating dampness removal, and nourishing the stomach, making them beneficial dietary therapy methods. Thirdly, well-cooked noodles can be eaten, as they also have a certain stomach-nourishing effect. Fourth, if consuming meat, it must be thoroughly stewed until soft before eating. This makes it less likely to burden the digestive tract and easier to digest, making it more suitable for patients with chronic gastritis.

Does gastritis infect people?

Regarding whether gastritis can be contagious, it requires specific analysis of the circumstances. If the gastritis is caused by an infection of Helicobacter pylori, then it can be transmitted to others through shared meals or fecal-oral transmission. Under such circumstances, if others do not maintain clean eating habits or overeat, they are at a higher risk of developing chronic gastritis. If the occurrence of gastritis is not due to an infection from Helicobacter pylori, then it will not be contagious to others. Patients with gastritis should be cautious with their diet, avoiding spicy and irritating foods, and should not overeat. It’s important to eat regularly and in moderate amounts, and maintain a bland diet.
