What causes vomiting on an empty stomach?

In real life, vomiting is a problem that many people will easily encounter, and vomiting on an empty stomach is also a common symptom. Generally, vomiting on an empty stomach is caused by gastritis. Gastritis can easily lead to abnormalities in the gastric mucosa, which can easily cause acid reflux or vomiting. You can take some medicines to treat gastritis, pay more attention to food supplements, and try not to feel hungry.

What causes vomiting on an empty stomach?

If you vomit on an empty stomach, you should pay attention to possible causes such as gastritis, indigestion, fatigue, staying up late, etc. Do not eat raw, cold, or spicy foods.

Causes

1. Causes of acute gastritis

It can be divided into two categories: exogenous and endogenous. Anything that enters the stomach through the mouth, such as bacteria, drugs, toxins, corrosives, etc., is considered an external factor. Any pathogenic factors that spread to the stomach wall through blood circulation or lymph are called internal factors.

(1) Physical and chemical factors: Strong tea, strong coffee, spicy food, strong liquor, overcold or overheated food, rough food, etc. can damage the gastric mucosa, destroy the mucosal barrier and cause gastric mucosal inflammation. Non-steroidal anti-inflammatory drugs such as aspirin, indomethacin, certain antibiotics, corticosteroids and other drugs can not only stimulate the gastric mucosa and cause damage, but also affect the repair of the gastric mucosa and aggravate inflammation. If certain strong corrosive agents such as nitric acid, hydrochloric acid, sulfuric acid, potassium hydroxide, sodium hydroxide, etc. are swallowed, it may cause acute corrosive gastritis.

(2) Biological factors mainly include various pathogenic bacteria and toxins, such as Salmonella, Escherichia coli, halophilic bacteria, Staphylococcus aureus toxin and botulinum toxin. Gastritis can occur within hours of eating food contaminated by bacteria or toxins. Pyogenic bacteria such as α-hemolytic streptococcus and Staphylococcus aureus spread to the stomach wall through the blood or lymph, causing acute purulent gastritis.

(3) Other stressful conditions such as systemic infection, severe trauma, major surgery, shock, and severe mood swings. Foreign bodies in the stomach, gastric stones, and radiotherapy to the gastric area can all cause this disease.

2. Causes of chronic gastritis

(1) Biological factors: The main pathogen of chronic gastritis is Helicobacter pylori, and more than 90% of patients with chronic gastritis are infected with Helicobacter pylori.

(2) Immune factors The onset of some chronic gastritis is related to immune factors, and parietal cell antibodies can be detected in the patient's serum.

(3) Physical factors such as long-term stimulation of the gastric mucosa by overcold or overheated food, rough food, strong tea, strong coffee, strong liquor, and spicy food can lead to repeated damage to the gastric mucosa and cause chronic gastritis.
