Don't Panic If Your Gastroscopy Report Shows Polyps! 5 Key Points to Understand What's Going On in Your Stomach
Seeing the words "gastric polyp" on a health screening report often keeps people up at night. In reality, the vast majority of gastric polyps — especially fundic gland polyps — are benign, and many do not even require treatment. The type that truly warrants heightened vigilance is the "adenomatous polyp," because this category carries a higher risk of malignant transformation. What matters is not how many polyps you have, but what the biopsy reveals about their "identity." As long as you follow your doctor's recommendations — removing what needs to be removed and monitoring what needs to be monitored — gastric polyps are really not that frightening.
"Doctor, be honest with me — how long do I have left to live?"
Hearing this sentence from a forty-five-year-old, normally calm and rational senior vice president in the finance industry was particularly heartbreaking. His name is Jian-Hong, and just one week ago he had completed a routine health screening. His gastroscopy report stated: "Several gastric polyps discovered; biopsies taken."
For the past few days, he had been unable to eat, his mind consumed by worst-case scenarios. His wife waited anxiously outside the consultation room, and their two children were still in junior high school.
The truth is that the vast majority of gastric polyps will never become cancer. But I understand his fear — the moment you see the word "polyp," for many people, the mind immediately leaps to the most terrifying images.
I quickly asked him to take a sip of water and gave him a reassuring pat on the shoulder. This kind of scene is all too common in the clinic. When we see words like "polyp" or "tumor," our instinctive reaction is to associate them with terminal illness.
But the human body works in fascinating ways. The stomach is like a field, and the things that grow on it are not necessarily toxic weeds that will kill you. More often than not, they are just little mushrooms that have sprouted because the environment changed.
Mr. Chen's report actually showed the most common benign condition, but he did not know that. This is precisely why I wanted to write this article. When you receive your report and see the red flags that make your heart race, do not rush to scare yourself.
We need to calm down and, like peeling an onion, examine this little thing growing in your stomach layer by layer to understand what it really is.
Some polyps are simply passing visitors, while others are distress signals from your body. In the following sections, I will use the simplest possible explanations to help you understand the true meaning behind these medical terms, and what you should do right now.
Why Does My Report Have Red Flags?
To understand gastric polyps, we need to use a bit of imagination. The stomach wall is not just a single layer of skin — it is a busy factory that must contend with strong acid, food abrasion, and various bacteria every day. Under this high-pressure environment, the gastric mucosa sometimes "grows extra tissue" — and that is a polyp.
Why do these things grow? There are usually two main reasons, which we can imagine as two different everyday scenarios.
The First Analogy: A Damp Lawn Covered in Mushrooms
Imagine you have a patch of lawn in your backyard. If, in an effort to make the grass grow well, you water and fertilize it excessively every day, changing the soil's pH, little mushrooms might suddenly pop up on the lawn.
These little mushrooms are what we commonly call "fundic gland polyps."
In medicine, this is often related to a type of medication we take — "Proton Pump Inhibitors (PPIs)," which are powerful stomach acid suppressants. These drugs primarily work by suppressing stomach acid, helping to treat gastroesophageal reflux disease or gastric ulcers. When the stomach's acidity is chronically reduced due to long-term medication use, the glands at the bottom of the stomach start thinking: "Hmm, why isn't there enough acid?" So they work hard to proliferate and expand, trying to maintain their function, and in the process, they grow into polyps that look like little blisters or little mushrooms.
These mushrooms are mostly harmless — they sprout simply because the environment (acidity) has changed. As long as the environment is restored, or even if you leave them alone, they typically will not turn into dangerous toxic weeds. So when you see this type of polyp that grew from "over-fertilizing," there is usually no need to worry.
The Second Analogy: Calluses on Your Palms
Now imagine a different scenario. If you are a carpenter who handles rough lumber with great force every day, over time, your palms will inevitably develop a thick layer of calluses.
These calluses are analogous to "hyperplastic polyps."
The appearance of this type of polyp usually indicates that there is a "battle" going on inside your stomach. The most common enemy is Helicobacter pylori, or chronic gastritis of long duration. When the gastric mucosa is constantly under bacterial attack and chronically inflamed, it activates its repair mechanisms to protect itself.
But if the repair process goes into overdrive, the result is a raised lump of tissue, much like a callus forming on the palm.
This callus is proof that the body has been injured. Although the callus itself is not necessarily a bad thing, it reminds us: "There are bacteria causing trouble here!" If you do not deal with the source of the trouble (such as H. pylori), this callus may grow larger and larger, and pathological changes may even develop around it.
So this type of polyp is a warning letter from your body, telling you it is time to go after the culprit.
What Does the Research Say?
Now that we have finished with analogies, we need to return to the serious medical evidence. According to the latest research guidelines, gastric polyps come in many varieties, and each type has its own "personality." We cannot paint them all with the same brush and treat them all as villains.
Next, I will discuss the most common types of polyps separately, and you will discover just how dramatically different their outcomes can be.
1. Fundic Gland Polyps: The Most Common Benign Neighbor
This is the most common type of gastric polyp in Western countries, and it is becoming increasingly prevalent in Taiwan as well. Research has found that it is most closely associated with two factors: one is long-term use of powerful stomach acid medications (PPIs), and the other is Familial Adenomatous Polyposis (FAP).
If these polyps arose from taking stomach medication, or are sporadic (no identifiable special cause), they are almost always benign.
So when do they need to be treated? According to the American Society for Gastrointestinal Endoscopy (ASGE) guidelines, only in a few uncommon situations will a physician recommend removal [1][2]:
- The polyp is 1 centimeter or larger.
- The polyp looks abnormal, with signs of dysplasia (meaning the cells are growing abnormally).
- You have a history of Familial Adenomatous Polyposis (FAP).
If your polyps are smaller than 1 centimeter and the biopsy confirms they are typical fundic gland polyps, regular monitoring alone is usually sufficient — there is no need for that extra procedure.
2. Hyperplastic Polyps: The Aftermath of Inflammation
This type of polyp is inseparable from chronic gastritis and H. pylori infection. Think of it as the product of your gastric mucosa enduring prolonged "redness, swelling, heat, and pain."
Although it behaves well most of the time, research shows it still has the "potential to turn bad." This is especially true when it grows larger (exceeding 0.5 to 1 centimeter), or when it is "pedunculated" (hanging from the stomach wall as if on a stalk) — in those cases, the risk is higher [2][3].
For this type of polyp, medical guidelines recommend the following:
- If the polyp exceeds 0.5 to 1 centimeter, removal is recommended.
- A very important point: physicians will typically also biopsy the mucosa adjacent to the polyp to check for H. pylori. If this bacterium is detected, eradication therapy is essential. Research confirms that once the bacteria are eliminated, these polyps often shrink or even disappear on their own [3].
3. Adenomatous Polyps: The Truly Dangerous Character
This is the type we least want to see, known as "gastric adenoma." While it is not yet cancer, it is a cancer candidate — what we call a "precancerous lesion."
For this type of polyp, the medical community takes a very firm stance. Regardless of size, the American Society for Gastrointestinal Endoscopy (ASGE) recommends: remove them all [2].
And removal is not the end of the story. You must return for a follow-up gastroscopy within one year after removal. If everything is clear, you should come back for surveillance every 3 to 5 years thereafter. This is because individuals with this predisposition may have a gastric mucosa that is already relatively fragile and prone to developing abnormal growths again.
4. Other Rare Types
There is also a type called "hamartomatous polyps," which are usually associated with specific genetic conditions (such as Peutz-Jeghers syndrome). These are relatively rare and require individualized management [4].
Additionally, there are "neuroendocrine tumors" (formerly called carcinoids). These require endoscopic ultrasound to assess how deep and how large they have grown. If they are small Type 1 tumors, they can be removed endoscopically. If they are large or represent the more aggressive Type 3, more intensive treatment may be necessary [2].
Finally, a reminder for everyone: although experienced endoscopists can make an educated guess about 80 to 90 percent of polyps based on appearance alone, research emphasizes that visual inspection alone is not accurate enough. In principle, all gastric polyps that are discovered should be biopsied or removed and sent to a pathologist for microscopic examination to arrive at a definitive diagnosis [2][5].
Do I Need Further Action?
After reading all this, I know you might feel a bit dizzy. To help you quickly match your own situation at a glance, I have organized this summary table. Take out your pathology report, look at the "Diagnosis" column, and you will have a general idea of what to do next.
- Fundic Gland Polyps: Like little mushrooms on a lawn, usually benign. Most do not need removal. Only remove if 1 cm or larger or if the appearance is abnormal. Who should be especially cautious: Those who take stomach medications long-term, or who have a family history of polyposis. Follow-up: Per physician recommendation; usually no intensive monitoring needed.
- Hyperplastic Polyps: Like a callus from an injury, related to inflammation. Larger ones should be removed (0.5–1 cm or larger). H. pylori testing and treatment are essential. Who should be especially cautious: Those with chronic gastritis or H. pylori infection. Follow-up: Return for confirmation as recommended by the physician after eradication therapy.
- Adenomatous Polyps: Dangerous! A cancer candidate. Remove them all! Regardless of size, every one must be removed. Who should be especially cautious: Middle-aged and elderly individuals, patients with atrophic gastritis. Follow-up: Recheck 1 year after removal, then every 3–5 years.
- Neuroendocrine Tumors: A more specialized type of cellular abnormality. Management depends on size and subtype. Small tumors can be removed; larger ones require further evaluation. Who should be especially cautious: Patients with autoimmune gastritis. Follow-up: Strict monitoring per specialist instructions.
Are There Any Side Effects or Risks?
Many patients, upon hearing "biopsy" or "removal," instinctively ask: "Will it hurt? Will it bleed?"
We must honestly address the risks of every medical procedure.
First, taking a "biopsy" (clipping a small piece of tissue for analysis) during gastroscopy is essentially painless. The gastric mucosa has no pain-sensing nerves. You might feel your abdomen is a bit bloated — that is because air is insufflated during the examination — but you will not experience the pain of being cut.
The real risk lies in "polypectomy" — the removal of polyps — especially when removing larger polyps. This is like performing a small surgical procedure inside the stomach.
The most common complication is bleeding. Most bleeding is minor and can be controlled by the physician during the procedure using hemostatic clips or electrocautery. In rare cases — usually involving large polyps or patients taking anticoagulant medications — there may be black stools or vomiting of blood after returning home, which requires immediate emergency department evaluation.
Another more serious risk is perforation — a small hole in the stomach wall. The probability of this occurring is very low, but the risk increases slightly when removing polyps with deep bases or large sizes. Modern endoscopic technology is very advanced, and many small perforations can be repaired on the spot with metal clips without the need for major surgery.
But let us consider the flip side — the risk of not investigating and not treating is actually greater.
As mentioned earlier, relying solely on the endoscopist's visual observation cannot determine with 100 percent certainty whether a polyp is benign or malignant [2][5]. Without a biopsy, we might miss an early adenoma, giving it the opportunity to become gastric cancer over the following years. The cost of a "missed diagnosis" far exceeds the minor wound from a biopsy.
Therefore, this is a matter of weighing the options. Accepting a very small risk of bleeding in order to confirm safety is an absolutely worthwhile investment.
What Does the Doctor Recommend?
After receiving your report, besides listening to the physician's explanation, what can you do in your daily life? Here are several specific action plans.
1. If Eradication Is Needed, Follow Through Completely
If your report shows "hyperplastic polyps" and H. pylori has been detected, please cooperate fully with your physician's prescribed antibiotic regimen.
Many people find taking antibiotics difficult — the course lasts one to two weeks, you may experience a bitter taste in your mouth, and sometimes diarrhea. But those two weeks of discomfort are the price of stopping the inflammation in your stomach. It is like putting out the fire at its source. Once the fire is extinguished, those "calluses" (polyps) that formed as a result of the burn have a chance to disappear.
Do not stop the medication on your own. If antibiotics are not taken for the full course, bacterial resistance develops, making them even harder to eliminate.
2. Review Your Stomach Medication List
If you have "fundic gland polyps" and are currently taking long-term PPIs (powerful stomach acid suppressants), consider discussing the following with the physician who prescribed your medication.
Do you really need a medication this strong? Could you switch to a different type of stomach medication? Or could you try reducing gastroesophageal reflux through dietary adjustments — eating fewer sweets, less coffee, fewer fried foods — thereby reducing your dependence on medication?
Of course, if your stomach ulcer is severe, you still need to take the medication. In that case, developing a few benign polyps is an acceptable trade-off. There is no need to throw the baby out with the bathwater.
3. Return to a Mild Diet and Give Your Stomach Time to Rest
Regardless of the type of polyp, its presence indicates that your gastric mucosa has been under a certain amount of stress. Imagine your stomach is injured right now — would you really have the heart to pour hard liquor or spicy hot pot into it?
Eat more fresh vegetables and fruits, and eat fewer pickled foods (such as preserved vegetables and cured meats) and smoked foods. These processed foods contain high levels of nitrites, which are accomplices to gastric cancer. Give your stomach a clean environment, and its self-repair ability is quite remarkable.
4. Set Your Calendar and Come Back When It Is Time
This is the point most easily forgotten. Many people feel "all clear" after polyp removal and never return for follow-up.
Especially for patients with "adenomatous polyps" — please take out your phone right now and set a calendar reminder for one year from now: "Schedule gastroscopy." Because your stomach has already demonstrated a predisposition to "growing abnormal things," the regular surveillance camera (gastroscopy) must never be turned off.
Common Misconceptions Clarified
In the consultation room, I frequently hear all kinds of urban legends about polyps. Some rumors sound so convincing they seem like facts, but they are all misunderstandings. Let us turn on the light and see what the truth looks like.
Myth 1: Does having any polyp at all mean it will definitely become gastric cancer?
Truth: Absolutely not. This is like saying "all mushrooms are poisonous" — it is simply wrong. As mentioned earlier, the most common type — fundic gland polyps — are almost always benign and will never become cancerous in a person's lifetime. Only "adenomatous polyps" are the truly dangerous characters. So when you see polyps, do not panic. Wait for the pathology report to come back and confirm which type it is — that is the key.
Myth 2: Once a polyp is removed, is it once and for all — will it never grow back?
Truth: Unfortunately, that is not the case. Removing polyps is like pulling weeds — you have cut down what was on the surface, but if the soil conditions have not changed (for example, H. pylori is still present, your genetic predisposition has not changed, your lifestyle habits remain the same), the weeds may grow back with the spring breeze. This is precisely why we emphasize the importance of "follow-up" so strongly. Removal addresses the current problem; follow-up is about preventing future trouble.
Myth 3: My friend had polyps removed during a colonoscopy — why did the doctor say my stomach polyps do not need to be removed?
Truth: The stomach and the colon are different organs, and the rules of the game are different. The vast majority of colon polyps are adenomas, all of which carry a risk of malignant transformation, so during a colonoscopy, the approach is almost always "see it, remove it." But a high proportion of gastric polyps (such as fundic gland polyps) are simple overgrowths with no risk of becoming cancerous. Removing them would only increase the risk of bleeding with no corresponding benefit. When your doctor chooses not to remove them, it is not laziness — it is a professional judgment based on medical guidelines, made to protect you from unnecessary wounds.
Conclusion
Think back to Mr. Chen. After I took the time to explain all these concepts, the tension in his face finally softened.
"Doctor, so my homework is just to maintain a healthy lifestyle, and then come back to see you in a year?" he asked.
"That's right," I said with a smile. "Think of this red flag as a gentle reminder card sent to you by your body. It is reminding you to slow down a little and pay some attention to the old partner that digests your food every day — it is not sentencing you to death."
Key Takeaways
The vast majority of gastric polyps are benign: Fundic gland polyps are the most common, typically associated with long-term use of stomach acid medications, and almost never become cancerous. If smaller than 1 centimeter, only monitoring is usually needed.
Adenomatous polyps are the truly dangerous ones: This type of polyp is a precancerous lesion. Regardless of size, removal is recommended, followed by annual gastroscopy surveillance.
H. pylori infection requires proactive treatment: Hyperplastic polyps are often associated with H. pylori. After eradication therapy, these polyps may shrink or even disappear on their own.
