Dr. Jess Bunyawongwirot Deputy Director of Primary Care Affairs Maharat Nakhon Ratchasima Hospital Facebook post of “Dr. Jed” giving knowledge about early warning signs of stomach cancer. By specifying the message: Anyone who has stomach pain, epigastric tightness, burning sensation and thinks it’s just acid reflux or gastritis. I took antacids and it felt better, so I let it pass.
Actually, there is another thing to be careful of. “Early stage stomach cancer” that often comes with symptoms similar to normal gastritis. This causes a delay in diagnosis if the same symptoms continue for more than 2–4 weeks or come and go without any obvious cause. You should start being careful. Today I will take you to do a basic self-check to see what are the early signs of stomach cancer?
1. Full stomach, feeling full abnormally quickly. After eating a few bites of rice, I feel full, my epigastrium is tight and I often feel bloated, even though the amount of food is not large. Some people feel like food stays in their stomach longer than usual, belch frequently, and discomfort in the upper part of their stomach.
If symptoms like this continue Especially in people over 40 years of age or with a family history of cancer. Should check further This is because small lumps in the stomach can interfere with the expansion of the stomach wall. Makes you feel full quickly without realizing it And it is often misunderstood that just the subsystem is not good.
2. Epigastric pain or chronic stomach pain The pain is usually not very severe. But it’s chronic. Taking antacids got better temporarily and then came back. Some people have pain that is not related to meals. Or pain even though you haven’t eaten anything spicy, sour, or coffee.
If the same pain persists for weeks, especially if it gets worse over time, don’t take treatment for granted because chronic inflammation of the stomach lining can develop into cellular dysfunction. Endoscopy will help distinguish whether it is just a normal wound or a lesion that needs a biopsy.
3. Unintentional weight loss Not on a diet Didn’t exercise more But there was a noticeable weight loss in 1–3 months. Clothes became looser. Tired more easily It may be caused by eating less because you are full quickly. Or the body has chronic inflammation from a tumor that uses high energy.
This is a “red flag,” especially if weight loss exceeds 5% of your body weight in a few months for no apparent reason. You should see a doctor immediately for a blood test and consider endoscopy. You shouldn’t think that it’s a good thing just because you’ve lost weight.
4. Nausea, vomiting or vomiting blood. In the early stages, it may just be chronic nausea, loss of appetite, or occasional mild vomiting. But if you start vomiting more often or vomiting blood Color similar to coffee grounds You must see a doctor immediately. Because there may be an ulcer or lump in the stomach that is bleeding.
Sometimes the bleeding is so small that it is not clearly noticeable. But it keeps accumulating, causing it to become pale without realizing it. Nausea that continues for several weeks without improvement after dietary adjustments should be investigated to determine the cause.
5. Black, pale stools, easily tiring. If there is slow bleeding in the stomach, if the stool is bright red blood. Usually comes from the large intestine. But if the photo is black like charcoal or asphalt It usually comes from the stomach or duodenum. There is an abnormal smell. and the body will gradually turn pale from blood loss Makes you tired easily, heart palpitations, dizziness. When you climb stairs or walk far, you will feel exhausted quickly.
Some people think it’s just a lack of rest or normal anemia. But if the anemia is unexplained The upper digestive tract should be examined. Because there may be a hidden source of bleeding in the stomach.
I don’t want to risk stomach cancer. What should I do?
- Test for H. pylori and treat stomach infections completely.
- Avoid extremely salty, fermented, and frequently grilled and charred foods.
- Quit smoking and reduce alcohol.
- If you have chronic stomach symptoms for more than 2–4 weeks, you should see a doctor. Do not buy medicine to take on your own.
- People with a family history of stomach cancer You should consult your doctor about screening colonoscopy.
- Choose to eat good, natural microbial foods. Or choose to supplement with probiotic strains. Bifidobacterium It helps stop the adhesion of H. pylori bacteria, but this is only an aid. It’s not a cure.
Early stages of stomach cancer often do not show severe symptoms, but will gradually send small, repeated signals to us if we pay attention to changes in the body and do not overlook chronic symptoms. Early detection increases the chance of cure much higher than in advanced stages. Don’t wait for severe pain or obvious bleeding to get tested. Because sometimes the best opportunities It is a test from the day the symptoms still appear to be not serious.
