Do you have stomach pain after eating? Could this be dumping syndrome?

After you eat a meal, do you sometimes feel dizzy, full, or have stomach cramps? Some people also feel tired and shaky a few hours after eating. If you have these symptoms, you may have a condition called dumping syndrome . Let's talk about this in detail today, because it can affect many people.

What is Dumping Syndrome?

Simply put, dumping syndrome is when the food in your stomach, or rather the contents of your stomach, moves into your small intestine, or what we commonly call your small intestine, faster than normal . Doctors also call this 'rapid gastric emptying'. Think of it as if the food in your stomach is being "dumped" into your small intestine in a big lump, before it can be properly digested.

So, when this happens, a large amount of undigested food passes into the small intestine at once, you may experience discomfort such as nausea, bloating, stomach cramps, and diarrhea . Not only that, but it can also cause sudden, large changes in your blood sugar levels.

What really happens in Dumping Syndrome?

Normally, when we eat, our stomach sends food slowly and in a controlled manner to the small intestine. This is done by the muscles, nerves, and hormones in the stomach, working in coordination. We call this "gastric motility."

However, in dumping syndrome, this coordination goes awry. The valve at the bottom of the stomach, the pyloric valve , opens before food is even digested, and the entire contents of the stomach are dumped into the small intestine at once.

What happens then? When the small intestine suddenly has a lot of undigested food, it tries to adjust to it. It draws in extra fluid and releases extra hormones. Those changes are what cause the discomfort we mentioned earlier shortly after eating.

Some people may experience other symptoms a few hours after eating. This is because blood sugar levels are changing. When a high-sugar meal suddenly hits the small intestine, our pancreas is signaled to release more insulin to control blood sugar. This can cause a sudden drop in blood sugar. This is called reactive hypoglycemia . This can cause things like dizziness, shakiness, and palpitations.

Who is more likely to develop dumping syndrome?

Dumping syndrome is most often a complication of gastric surgery. It is estimated that between 20% and 50% of people who have had gastric surgery will experience these symptoms to some degree. It is especially common in people who have had surgery that removes a large part of the stomach, such as a gastrectomy (removal of all or part of the stomach) or gastric bypass surgery (a weight loss surgery that bypasses part of the stomach). Very rarely, it can also be caused by certain intestinal conditions.

Is Dumping Syndrome a serious condition?

Usually, dumping syndrome is not dangerous or life-threatening. However, if the condition is severe, it can lead to rapid weight loss and nutritional deficiencies. If the diarrhea is not controlled, it can lead to dehydration. But most of the time, these can be controlled.

Most people have mild symptoms that go away over time. Dumping syndrome is usually not permanent, so there's nothing to worry about.

What are the symptoms of dumping syndrome?

There are two main stages of dumping syndrome, with symptoms associated with each stage. You may experience either or both of these stages.

Early dumping syndrome symptoms

These usually start to occur between 10 and 30 minutes after you eat .

• Nausea
• Vomiting
• Diarrhea (stomach ache)
• Stomach pain and limping
• Bloating, bloated feeling
• Dizziness, fainting
• Increased heart rate (feeling like your chest is pounding)

Late dumping syndrome symptoms that occur a few hours after eating

These symptoms usually appear two to three hours after eating .

• Weakness, fatigue
• Trembling, restlessness
• Rapid or irregular heartbeat
• Cold sweat
• Redness of the face
• Brain fog - a feeling of difficulty thinking clearly
• Feeling very hungry

What are the causes of dumping syndrome?

There are two main categories of reasons for this.

Surgery-related reasons:

• Gastrectomy: A surgery to remove part or all of the stomach.
• Bariatric surgery: Surgery performed to reduce weight, for example, gastric bypass surgery.
• Pyloroplasty: A surgery performed on the pyloric valve at the bottom of the stomach.
• Esophagectomy: A surgery to remove part or all of the esophagus.
• Vagotomy: A surgical procedure that cuts the vagus nerve in the stomach to reduce stomach acid.
• Nissen fundoplication: A surgery to sew the upper part of the stomach around the esophagus (done for gastroesophageal reflux disease - GERD).

Disease-related causes:

Dumping syndrome can also be caused by certain medical conditions.

• Diabetes (Diabetes Mellitus)
• Cyclic vomiting syndrome
• Autonomic dysfunction
• Exocrine pancreatic insufficiency
• Duodenal ulcers
• Zollinger-Ellison syndrome
• Functional dyspepsia
• Cannabis hyperemesis syndrome ( a condition of excessive vomiting due to cannabis use)

How to recognize dumping syndrome?

If you've had previous stomach surgery (even if it was years ago), your doctor may suspect dumping syndrome based on the symptoms you're describing. They may give you a questionnaire, such as the Dumping Symptom Rating Scale , to measure the severity of your symptoms.

However, your doctor may also do some tests to confirm the diagnosis or to rule out other causes. These tests are especially important if you have not had stomach surgery.

Here are some tests that can be done to diagnose dumping syndrome:

• Oral glucose tolerance test: This involves giving you a sugary drink and measuring your blood sugar levels before and after. Your hematocrit , which is the percentage of red blood cells, is also measured. An increase in your hematocrit after drinking the sugary drink means that more fluid is being drawn from your blood into your intestines. If your blood sugar drops within one to three hours, this is called delayed dumping syndrome.
• Hydrogen breath test: This also measures the amount of hydrogen in your breath after you drink a glucose solution. Hydrogen in your breath means that your small intestine is not absorbing glucose properly. This means that the small intestine is overloaded.
• Upper endoscopy: This involves inserting a thin, flexible tube (endoscope) with a camera attached through the mouth and examining the inside of the esophagus, stomach, and duodenum (the first part of the small intestine). This can help determine if there are structural problems or other causes for your symptoms.
• Upper GI series: In this test , you drink a special liquid (contrast solution) and a series of video X-rays (called `fluoroscopy`) are used to watch the liquid as it moves through your esophagus, stomach, and upper small intestine. This can show how fast the liquid is moving.
• Gastric emptying test: This measures how quickly food empties from your stomach. A very small amount of radioactive material is added to the food you eat. Then, using a special scanner, your doctor can watch the food move through your stomach.

How to get rid of dumping syndrome?

Many people can successfully manage dumping syndrome by making dietary changes . For severe symptoms, if diet alone does not help, medication may be used. However, medication can have side effects, so it is not recommended for long-term use. In rare cases, if dumping syndrome is caused by surgery and no other treatment has helped, your doctor may recommend another surgery.

Dietary guidelines

Doctors recommend following these tips to reduce symptoms:

• Reduce the amount of food you eat at one meal and increase the number of meals you eat throughout the day. Instead of three large meals, try eating six small meals.
• Eat your food slowly and chew it well. This will make digestion easier.
• Reduce your intake of simple sugars, high-carb foods, and dairy products as much as possible. These will help prevent sudden changes in blood sugar. Complex carbs, such as whole grains, are better.
• Reduce carbohydrates from your diet and add more protein and healthy fats instead. Fats are slow to digest and provide a steady source of energy.
• Eat more foods rich in dietary fiber. This adds bulk to food, slowing its movement through the intestines. Fiber also controls the absorption of sugar.
• Lie down (upright) for about 30 minutes after eating. This can slow down the emptying of food from the stomach and help maintain blood pressure during digestion.
• Do not drink water or other beverages 30 minutes before or after eating. Liquids increase stomach motility.

Medications

Some medications can help control the early and late symptoms of dumping syndrome.

• Octreotide acetate: Octreotide blocks the action of certain hormones in our digestive system. This slows down the emptying of food from the stomach and the movement of food through the small intestine. It also reduces insulin production. This medication is given as an injection, either daily (short-acting) or monthly (long-acting).
• Acarbose: This medication slows down the rate at which our body absorbs carbohydrates, controlling blood sugar levels. It has been shown to reduce the hypoglycemia that occurs in late dumping syndrome.

Surgery

Surgery is rarely recommended for dumping syndrome. However, if your condition is caused by surgery, another surgery may be able to correct it. If dumping syndrome is severely affecting your quality of life and nothing else works, you may want to consider reconstructive surgery. This involves:

• Reconstructing or modifying a part of the stomach that is not working well.
• Reversing surgeries like gastric bypass or switching to a less invasive option.

Will dumping syndrome go away completely?

Yes, it usually goes away with time. Mild early dumping syndrome usually resolves within about three months. More severe cases and late-onset dumping syndrome can take 12 to 18 months to resolve. In the meantime, dietary changes can provide significant relief. However, it can take several weeks to see improvement. So it's important to be patient.

What foods should you eat and what foods should you avoid when you have dumping syndrome?

It is very important for people with this condition, especially after gastric surgery, to follow a diet plan that helps control symptoms. The points we discussed earlier under "Dietary Changes" apply here as well:

• Things to eat: Protein-rich foods (fish, chicken, eggs, lentils), healthy fats (avocado, nuts), complex carbohydrates rich in fiber (brown rice, oats, vegetables).
• Things to avoid or limit: Simple sugars (sweetened drinks, sweets, cakes), highly refined carbohydrates (things made from bread flour), milk and dairy products (some people may find it difficult to digest), high-fat, fried foods.

It's best to talk to your doctor or nutritionist to create a meal plan that's right for you.

Finally, take-home message:

Dumping syndrome is a condition that many people experience after gastric bypass surgery. You may also experience these symptoms after surgery. The good news is that most of the time, it is a mild condition and will resolve on its own within a few weeks or months. In the meantime, you can manage this condition by adjusting your diet accordingly.

If you are going to have stomach surgery in the future, it is wise to plan a diet that is suitable for dumping syndrome. Prepare the kitchen and have a few meal plans in mind. If you have made dietary changes and they do not bring relief, be sure to see your doctor. He or she can prescribe the necessary medications to help you during your recovery. So, the most important thing is to not panic, be informed, and take the necessary steps.
