Slimming is usually caused by serious diseases or long-term diseases, mainly due to the obvious increase in consumption caused by diseases or insufficient food intake caused by diseases. Extremely thin patients are called cachexia.
There are acute and chronic gastritis, while common gastritis is mainly caused by long-term eating spicy and irritating greasy food, long-term drinking and smoking, long-term taking of some non-steroidal anti-inflammatory drugs, helicobacter pylori infection and other factors, which leads to edema and congestion of gastric mucosa and abnormal gastric acid secretion, resulting in acid reflux, heartburn, nausea and vomiting, easy hunger and other symptoms, so common gastritis will not lead to weight loss.
But the main cause of emaciation in a short time is gastric cancer, because the main typical symptom of cancer is emaciation. Gastric cancer is mainly a malignant tumor in the stomach caused by eating habits, Helicobacter pylori infection, environmental factors, heredity and other factors. Tumors need a lot of blood supply and nutrition absorption during their growth, so they will compete with the human body to absorb nutrition, leading to malnutrition and loss of appetite in the short term.
Although atrophic gastritis is also a kind of gastritis, it can also lead to emaciation, but not in a short time. Atrophic gastritis leads to atrophy of gastric glands due to various factors, which leads to indigestion, loss of appetite and digestive absorption disorders in the stomach. Moreover, the long-term existence of atrophic gastritis will lead to epithelial dysplasia and intestinal metaplasia, which is easy to induce gastric cancer.
