What are the early symptoms of stomach pain and nausea?
Gastric cancer is a very common malignant tumor among humans. It has a very high incidence rate and poses a great threat to human health. However, if the patient can pay attention, it can be found in time. So what do you know about the early symptoms of gastric cancer? What is the cause of gastric cancer? The performance of gastric cancer is mainly gastrointestinal symptoms, such as abdominal pain, nausea, loss of appetite and so on. However, some patients with gastric cancer, the symptoms are mainly "extra-gastric" performance, such as anemia, dermatomyositis and so on.
The early symptoms of gastric cancer have these 4
1, abdominal pain symptoms:
Gastric cancer causes an inflammatory infiltrate that penetrates the serosa to invade the pancreas or the transverse mesocolon, thereby inducing persistent severe pain and radiating to the lower back. Patients with very few perforation of cancerous ulcers may also experience abdominal pain and signs of peritoneal irritation.
2, nausea and vomiting symptoms:
Nausea and vomiting are also one of the more common early symptoms of gastric cancer. In addition, cancers of the gastric antrum can also present with pyloric obstruction.
3, vomiting blood, black stool symptoms:
When the surface of the cancer forms an ulcer, the patient also presents with vomiting and melena symptoms. Clinically, one-third of patients with gastric cancer often experience a small amount of bleeding. Most of them show positive fecal occult blood, some may have intermittent melena, and a large amount of vomiting.
4, loss of appetite, weight loss symptoms:
Absorption of cancerous toxins by patients with gastric cancer will cause them to show signs of weight loss, anemia, fatigue, malnutrition, etc., and they will tend to be progressively aggravated until they finally show dyscrasia.
The early symptoms of gastric cancer are as described above. In fact, the early symptoms of gastric cancer are similar to the symptoms of atrophic gastritis. Moreover, atrophic gastritis is also recognized as a precancerous condition.
How to detect early gastric cancer
1. Improve alertness and awareness of gastric cancer. Nearly half of patients with early gastric cancer have no clinical symptoms, and only some have mild dyspepsia and other symptoms such as abdominal discomfort, slight fullness, pain, nausea, and belching. Most of the patients are already in the middle and late stages of treatment. The reason is that people generally have misunderstandings about gastric cancer. If there are symptoms such as mild eating obstruction, epigastric pain, loss of appetite and other symptoms, it is less than a doctor's visit, taking a commercially-available stomach medicine; faced with unexplained weight loss, fatigue, and other symptoms, they often feel that they are working fatigue and stress. To. Various conditions can not be diagnosed early. Therefore, once the elderly have upper abdominal pain, bloating, weight loss, difficulty swallowing, etc., they must be vigilant.
2, check and treat precancerous lesions. The World Health Organization has classified patients with chronic atrophic gastritis, intestinal metaplasia, dysplasia of gastric mucosa, gastric ulcer, gastric polyps, and benign stomach diseases as major precancerous gastric lesions. Patients with Helicobacter pylori infection (gastric Helicobacter pylori infection positive persons are three to six times the risk of gastric cancer) should be checked and treated regularly.
3, gastroscopy. Gastroscopy diagnosis should be the first choice for the diagnosis of early gastric cancer. Gastroscopy can quickly obtain early pathological diagnosis for patients with suspected ulcers, gastric mucosal dysplasia or gastric cancer.
4, image inspection. X-ray double contrast angiography is also a method for early detection of lesions, but for diagnosis, gastroscopy should be mobilized and biopsy should be performed to obtain a pathological diagnosis.
5, ultrasound endoscopy. There is now a new type of gastroscope that can be fitted with an ultrasound probe. Early diagnosis can be made for gastric uplift lesions such as submucosal or extra- gastric tumors, and it can clearly show the structure of the stomach wall and the depth of tumor invasion.
6, must observe the suspicious patient to observe, in 1 to 3 months review once.
Preventing gastric cancer should also keep in mind the six key points of life.
1. Regular, quantitative diet, avoid overeating, eating too hot food, so as not to stimulate or damage the gastric mucosa.
2. Eat more foods containing Vitamins A, B, E, and beta-carotene; increase protein and soy products and increase resistance.
3. Contaminated water contains a variety of carcinogenic metal ions, must drink tap water or purified water.
4. Many patients with gastric cancer are introverted and talkative. Chinese medicine believes that depressed and depressed moods are prone to qi stagnation and blood stasis and cancer.
5. Pickles contain large amounts of nitrites and secondary amines. They can synthesize nitrosamines in the stomach under the action of suitable acidity or bacteria. Such compounds are strong carcinogens. Fried, baked, and burned foods also contain such carcinogens.
6. People suffering from atrophic gastritis, gastric ulcer, gastric multiple adenomatous polyps, and pernicious anemia must be checked and treated regularly to eliminate precancerous lesions and prevent gastric cancer. In addition, the incidence of cancer family history is significantly higher than the average person.
