• Nausea and / or vomiting;
• Heartburn (heartburn);
• Stomach cramps;

• Intolerance to carbohydrates;
• Intolerance to alcohol;
• Fructose intolerance (rare genetic disorder);

Gastritis
Gastritis is inflammation of the stomach lining and is accompanied by the following symptoms:

• Nausea and vomiting;
• Lack of appetite;
• Dyspepsia (gastrointestinal symptoms, indigestion);
• Excessive belching;
• Bloating;

The main causes of the disease are excessive alcohol consumption or prolonged administration of anti-inflammatory drugs (NSAIDs) such as aspirin and ibuprofen. In some cases, gastritis develops as a result of major surgery, bacterial infection (Helicobacter pylori), periods of strong stress.
The condition can be prevented by:

• Establishing a healthy diet;
• Limiting or avoiding alcohol;
• Stopping smoking;
• Avoid excessive painkillers.

Gastric ulcer
Gastric ulcer was manifested by symptoms of burning pain and nausea, high intensity night in the absence of supply (on an empty stomach), but improved after meal.

• Smoking;
• Family history of disease;
• Inappropriate diet in the presence of sedentary or overweight;

Zollinger-Ellison Syndrome
