What is HP positive?
In recent years, with the increase of health awareness, infection with Helicobacter pylori (HP) has become a hot topic. HP positive means that the presence of this bacteria has been detected in the human body, which is closely related to diseases such as gastritis, gastric ulcers and even gastric cancer. This article will combine the hot topics of the past 10 days to fully analyze HP positive for you from the aspects of definition, symptoms, detection methods, treatment and prevention.
1. Definition of HP Positiveness
Helicobacter pylori is a Gram-negative bacteria that mainly parasitizes in the gastric mucosa. HP positive means that the presence of the bacteria is confirmed by medical tests such as breath tests, blood tests, or gastroscopy. According to statistics, about 50% of the world's population is infected with HP, and the infection rate in developing countries is higher.
| area | Infection rate |
|---|---|
| Global Average | About 50% |
| China | About 60%-70% |
| European and American homes | About 30%-40% |
2. Symptoms of HP Positive
Not all HP infections experience symptoms, but common symptoms include:
| Symptom Types | Specific performance |
|---|---|
| Upper gastrointestinal symptoms | Stomach pain, abdominal distension, belching, acid reflux |
| Systemic symptoms | Loss of appetite, weight loss, fatigue |
| Oral symptoms | Bad breath, oral odor |
It is worth noting that some infected people may have asymptomatic symptoms for a long time, but bacteria will continue to damage the gastric mucosa.
3. HP positive detection method
One of the hot topics in the medical community in the past 10 days is the advancement of non-invasive detection technology. The following is a comparison of mainstream detection methods:
| Detection method | advantage | shortcoming |
|---|---|---|
| Urea breath test | Non-invasive, high accuracy (>95%) | Need to be on an empty stomach, affected by recent drugs |
| Fecal antigen detection | Suitable for children, no radiation | High sample preservation requirements |
| Serological test | Easy to operate | Can't distinguish between prevalence/previous infections |
| Gastroscopy biopsy | Gold standard, can observe stomach lesions at the same time | Invasive, high cost |
4. HP positive treatment plan
Recent international guidelines emphasize"Individualized Treatment"and"Antibiotic resistance monitoring". Standard quadruple therapy (14-day course) is still the first-line choice:
| Drug Type | Representative medicine | effect |
|---|---|---|
| Proton pump inhibitor | Omeprazole | Inhibit gastric acid secretion |
| Bismuth agent | Potassium bismuth citrate | Protect the gastric mucosa |
| Antibiotic 1 | Amoxicillin | Kill HP |
| Antibiotic 2 | Clarin | Kill HP |
5. Hot suggestions for preventing HP infection
Combining the latest research and public health recommendations:
1.Separate meals: Avoid sharing of tableware and reduce the risk of oral-oral transmission
2.Food Safety: Do not eat raw food, and regularly disinfect tableware
3.Oral hygiene: HP can survive plaque and keep your mouth clean
4.Screening awareness: People with a family history of gastric cancer should be tested regularly
6. Latest research progress on HP (hot spots in the past 10 days)
1.Vaccine development: A team announced that the oral vaccine has entered phase II clinical trial
2.Microecological Therapy: Adjuvant treatment of probiotics can improve eradication rate by 5-10%.
3.Drug resistance monitoring: my country's clarithromycin resistance rate has reached 20-30%
In summary, HP positive is a health signal worthy of attention, but it can be completely controlled through standardized treatment and scientific prevention. It is recommended that those with symptoms seek medical treatment in a timely manner, and the effect should be checked after eradication and treatment. Maintaining a healthy lifestyle and regular physical examinations are the fundamental way to protect your stomach health.
