What symptoms can Helicobacter pylori cause in the body?

Helicobacter pylori is a very common pathogen in some patients with gastritis and gastric ulcers. The appearance of Helicobacter pylori can actually cause great damage to the patient's body. If Helicobacter pylori is not treated in time, it can cause great harm to the patient's body and cause gastric cancer, so friends must pay attention to it in time.

Helicobacter pylori is a spiral-shaped, slightly anaerobic, Gram-negative bacillus that has very strict requirements for growth conditions. It was first successfully isolated from gastric mucosal biopsy tissue of patients with chronic active gastritis in 1983 and is the only known type of microorganism that can survive in the human stomach. Helicobacter pylori disease includes gastritis, peptic ulcer, lymphoproliferative gastric lymphoma, etc. caused by Helicobacter pylori infection. The adverse prognosis of Helicobacter pylori infection is gastric cancer.

Caused diseases

Helicobacter pylori disease includes gastritis, peptic ulcer, lymphoproliferative gastric lymphoma, etc. caused by Helicobacter pylori infection.

harm

The poor prognosis of Helicobacter pylori disease is gastric cancer.

Gastric cancer is one of the most common malignant tumors worldwide and ranks second among the causes of cancer death. In our country, about 160,000 people die from gastric cancer every year.

Clinical manifestations

The prevention and control of gastric cancer has attracted increasing attention. Studies have shown that Helicobacter pylori lives in the pyloric area of ​​the human stomach and is one of the most common bacterial pathogens. More than half of the world's population has been infected with Helicobacter pylori, and in some countries almost 90% of the population has been infected with this bacterium. People are usually infected at a young age, reaching 50% by the age of 5. This bacterial infection first causes chronic gastritis, and then leads to gastric ulcers and gastric atrophy, and in severe cases develops into gastric cancer. According to statistics, the incidence of atrophic gastritis and gastric cancer is high among people who are first infected with Helicobacter pylori at an early age, and there is a parallel relationship between Helicobacter pylori infection and gastric cancer mortality. Helicobacter pylori parasitizes in the gastric mucosal tissue. 67% to 80% of gastric ulcers and 95% of duodenal ulcers are caused by Helicobacter pylori. Common symptoms of patients with chronic gastritis and peptic ulcers are: upper abdominal fullness, discomfort or pain after eating, often accompanied by other adverse symptoms such as fever, bloating, acid reflux and loss of appetite. Some patients may also experience recurrent severe abdominal pain, small amounts of upper gastrointestinal bleeding, etc. Based on this, experts believe that early detection of Helicobacter pylori infection and timely and effective use of antibiotics to kill Helicobacter pylori are of great significance for the prevention and control of gastric cancer.
