Gastroenteritis is an inflammation of the digestive system, especially of the stomach and intestines. It is typically caused by a virus, bacteria, or parasite and can be mild or severe. Symptoms include nausea, vomiting, diarrhea, abdominal pain, and fever. Diagnosis is typically made by taking a medical history and physical exam, followed by laboratory tests and imaging studies. Treatment may involve antibiotics, antidiarrheal medications, and supportive care. In severe cases, hospitalization may be necessary. Prevention is best achieved by practicing good hand hygiene and avoiding contaminated food and water.
Gastritis is an inflammation of the lining of the stomach. It can be caused by stress, medications, infections, and other medical conditions. Symptoms of gastritis may include abdominal pain, nausea, vomiting, bloating, and burning sensation in the upper abdomen. Additional symptoms can also include loss of appetite, indigestion, and black, tarry stools.
The cause of gastritis may vary depending on the individual, but common causes can include bacterial infection, long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs), alcohol consumption, and stress. In some cases, gastritis can be caused by autoimmune disorders, such as Crohn’s disease, or other medical conditions, such as pernicious anemia.
Gastritis is usually diagnosed based on a physical examination, endoscopy, and other tests. Endoscopy is a procedure that uses a lighted tube to look inside the stomach. Other tests may include blood tests, stool tests, and biopsies.
Treatment of gastritis typically includes medications to reduce acid levels in the stomach, as well as antibiotics and antacids. Adopting a healthy diet and lifestyle can also help to reduce symptoms and prevent further damage to the stomach lining. Additionally, avoiding NSAIDs, alcohol, and other irritants can help to prevent the recurrence of gastritis in the future.
Gastric cancer, also known as stomach cancer, is a type of cancer that develops in the lining of the stomach. Symptoms of gastric cancer can include persistent indigestion, abdominal pain, heartburn, nausea, vomiting, difficulty swallowing, and weight loss. Diagnosis is usually made through a combination of imaging tests, such as X-rays and CT scans, and biopsies, which involve taking a small sample of tissue from the stomach for examination. Treatment for gastric cancer typically involves surgery, chemotherapy, and radiation therapy. Surgery involves removing the tumor, while chemotherapy and radiation are used to destroy any remaining cancer cells.
