Total gastrectomy is indicated in the treatment of gastric cancer in patients with large tumors that cannot be treated with tumor resection, chemotherapy, or radiation therapy.

3. What happens after total gastrectomy?
The stomach is an important organ in the digestive system that plays a role in receiving food and preparing it before it is transferred to the small intestine. Therefore, many patients wonder that if the stomach is removed, will the digestive system work normally and how will nutrients be provided?
After surgery:
After gastrectomy, the patient is provided with nutrients by intravenous route including: water, sugar, amino acids, electrolytes to ensure energy for the body.
After 5 days, the patient can eat light foods such as milk, diluted porridge, ... many times a day. It is necessary to divide meals into several times, about 100ml each time for the digestive system to get used to. After a few weeks, you can eat rice normally.
In addition, the patient may face some complications such as:
Dumping syndrome:
This is a syndrome that occurs because food moves into the small intestine too quickly because the stomach is cut so the digestive function is not as usual. Patients have symptoms of abdominal pain, diarrhea, nausea, dizziness.. In mild cases, it can be controlled by reducing sugar in the daily diet and dividing meals. More severe cases of Dumping syndrome require surgical intervention.
This syndrome usually does not affect the patient's health much, but only causes discomfort in daily life. After about 3 months, the condition will usually go away on its own.

After gastric bypass surgery, the patient must use medication in combination with a strict diet with liquid food, which will make the patient lose weight in the first time. When health has recovered with a normal diet, the weight will be more improved.
Lactose intolerance:
Caused by a deficiency of the enzyme Lactase that helps digest this nutrient, this contributes to why after eating foods rich in lactose such as milk, cheese,... diarrhea.
Poor absorption of fat:
Because the stomach has been cut, food is stored in the intestine quickly, the contact time of food with digestive enzymes is poor, leading to poor absorption of fat. Food that goes straight to the small intestine is not processed by the stomach, so it is large in size, difficult for pancreatic enzymes to digest and absorb, making the patient reduce absorption of fat-soluble vitamins such as vitamins A, D, E, K.
Digestive disorders:
The first time after removing the entire stomach will have digestive problems such as: flatulence, bloating, indigestion, long fullness, vomiting, ... Can be overcome by Ways to implement a more suitable diet such as: dividing into many small meals, preparing thin and soft foods, enhancing vitamins that are difficult to absorb.
