Your stomach is the vital organ that stores the food you eat and starts the very first steps of digestion. Sometimes, due to severe conditions like stomach cancer or advanced ulcers, your doctor may recommend removing part or all of your stomach.
This surgical procedure is known as a gastrectomy. While it sounds like a major medical event, many people go on to live full, healthy lives after their bodies adjust to the change.
Key Takeaways
- A gastrectomy involves removing part or all of your stomach to treat conditions like cancer, severe ulcers, or severe obesity.

What is a Gastrectomy?
Simply put, a gastrectomy is a surgical operation to remove either a portion of your stomach or your entire stomach. Your normal stomach holds your food for a short time, breaks it down, and passes it smoothly to your small intestine to absorb essential nutrients.
There are two main types of gastrectomy procedures:
- Total Gastrectomy: In this procedure, your surgeon removes your entire stomach.
- Partial Gastrectomy: In this procedure, your surgeon removes only a portion of your stomach. Depending on how much is removed, it may be called a subtotal gastrectomy, where roughly 80 percent of the stomach is taken out. Weight-loss procedures like a gastric sleeve are also a form of partial gastrectomy.
Why is This Surgery Performed?
Most of the time, doctors perform a gastrectomy to treat stomach cancer. The surgery helps cure the disease or stop it from spreading to other parts of your body. In cases where cancer cannot be cured, the surgery helps control painful symptoms and bleeding.
Besides cancer, doctors use gastrectomy to treat several other medical conditions. Usually, doctors try medicines and lifestyle changes first, and consider surgery as a final treatment option when other methods fail.
| Medical Condition | Description |
|---|---|
| Benign Tumors | Removing non-cancerous growths that cause uncomfortable symptoms or might turn into cancer later. |
| Severe Gastritis | Treating severe, chronic inflammation of the stomach lining that does not respond to medicine. |
| Peptic Ulcer Disease | Healing painful, stubborn sores in the stomach wall that refuse to heal normally. |
| Severe Obesity | Performing weight-loss surgery to control health risks linked to extreme weight. |
| Stomach Injuries | Repairing severe physical damage to stomach tissues from an accident that cannot heal on its own. |
| Inherited Cancer Risk | Preventing stomach cancer when a genetic mutation, such as in the CDH1 gene, runs in your family. |

Because a gastrectomy is a major surgery, preparing well ahead of time is very important for a smooth operation and recovery.
- Talk to Your Doctor: Share your complete medical history, every medicine you take, vitamins, herbal remedies, and any allergies you have.
- Improve Your Health: Try to reach your best possible physical shape before surgery by following your doctor's advice on diet and light activity.
- Stop Smoking: If you smoke, stop completely a few weeks before your surgery date to greatly improve your healing results.
- Adjust Your Medicines: Your doctor will tell you if you need to pause certain medicines like blood thinners, nonsteroidal anti-inflammatory drugs, aspirin, or warfarin.
- Fast Before Surgery: You must avoid eating or drinking anything for several hours before the procedure. Follow your care team's timing instructions carefully.
- Arrange Help at Home: Plan for someone to drive you home from the hospital. Having a family member or friend help with daily chores during early recovery makes things much easier.
What Happens During the Surgery?
During the surgery, you will receive general anesthesia so you stay sound asleep and feel zero pain throughout the entire procedure.
1. Anesthesia: An intravenous medicine delivered through your vein puts you into a deep sleep before the operation begins.
2. Catheter Placement: A small tube called a catheter goes into your bladder to drain urine. Another tube called a nasogastric tube goes through your nose down into your stomach to clear out fluids. Doctors can also use this tube later to give you medicine and nutrition.
3. Removing the Stomach: Your surgeon performs either an open surgery through a single larger cut or a laparoscopic surgery through several small cuts using a tiny camera. If treating cancer, the surgeon also removes nearby lymph nodes to check for any spread.
4. Reconnecting the Digestive Tract: This step is critical. Your surgeon carefully reconnects your remaining digestive path. If part of your stomach was removed, the remaining part connects directly to your small intestine. If your entire stomach was removed, your surgeon connects your esophagus straight to your small intestine.
5. Closing the Incisions: Finally, the surgical team closes all cuts with stitches or surgical staples.
Note: This surgery usually takes about five hours, though the exact time varies depending on the specific type of procedure you need.
Recovery and Healing Timeline
After surgery, you will typically stay in the hospital for about one to two weeks while the medical staff monitors your healing progress.
- Eating and Drinking: At first, your body receives nutrition through an intravenous line or a feeding tube. As your surgical cuts heal, you will slowly start drinking clear liquids by mouth, then progress to soft foods like broths and porridges, and eventually return to regular light meals.
- Pain Management: Your care team will provide appropriate medicine to keep you comfortable and manage your post-surgery pain.
- Healing Period: Recovering takes many months. Your surgical wounds take about two months to heal. Regaining your strength and getting used to your new eating routine takes three to six months or even longer. Be patient and give your body the time it needs to heal.
Risks and Complications
Like any major surgery, a gastrectomy carries general risks such as infections, allergic reactions to anesthesia, and blood clots. In addition, this specific operation can lead to a few unique complications.
| Complication | Simple Explanation |
|---|---|
| Anastomotic Leak | Food leaking out from the newly joined surgical connections or stitches. |
| Dumping Syndrome | Food moving too quickly into your small intestine before proper digestion. This causes bloating, nausea, stomach pain, or diarrhea. |
| Malnutrition | Difficulty absorbing enough nutrients, which can lead to conditions like anemia. |
| Bile Reflux | Digestive fluid from your liver flowing backward up into your remaining stomach or esophagus. |
| Internal Hernia | A loop of the small intestine pushing through another part of your abdomen, which requires urgent medical attention. |
If you experience any unusual discomfort or troubling symptoms, contact your doctor right away.
Living a Normal Life After Gastrectomy
Yes, absolutely! You can live a healthy and fulfilling life after your surgery. However, you will need to adapt to a new normal when it comes to eating and daily habits.
- Eat Small and Often: Instead of eating three large meals each day, switch to eating about six small meals spread across the day.
- Modify Your Choices: High-fiber foods like whole grains, heavy bread, and dairy products can be hard to digest early on. Experiment carefully to find out which foods suit your body best.
- Vitamins and Supplements: Because your stomach is missing or smaller, your body struggles to absorb certain nutrients, especially vitamin B12. Take prescribed vitamins and nutritional supplements faithfully under your doctor's guidance.
- Rest and Gentle Exercise: Get plenty of rest. Engage in light physical activity like walking without straining your body. Walking helps prevent serious complications like blood clots.
When to Contact Your Doctor

- Persistent nausea and vomiting .
- Frequent diarrhea .
- Severe stomach pain or bloating .

Emergency Red Flags
