What Is Dumping Syndrome?

After stomach reduction or bariatric surgery, it takes time for the body to accept the reorganization of the stomach and intestines applied in these restrictive procedures. During this process, patients must pay attention to their diet and what is eaten. Otherwise, they might encounter extremely serious complications such as dumping syndrome. In this article, we will discuss dumping syndrome in detail so that you will know what it exactly is, what its symptoms are, and how it can be prevented or cured. rapid gastric emptying that occurs after weight-loss surgical procedures in response to the rapid passage of stomach contents (consumed foods) into the small intestine as a result of regulation and its hyperextension.As a result, some hormones like serotonin and vasoactive intestinal polypeptide are released. This complication causes discomfort due to hemodynamic and neurovegetative disorders and can have severe impacts on the health-related quality of patients’ lives.The most destructive damage dumping syndrome creates is trouble in the absorption of nutrients from food, especially calcium absorption, which will result in anemia, weakened bones, or a low amount of red blood cells.It is extremely important for people to comply with the diet given by their doctor so that they won’t experience this difficulty after the gastro-resection procedure.

Early Dumping Syndrome

Early dumping syndrome occurs within 30 minutes of eating. In this syndrome, the processed food particles the patient consumes pass through the stomach log quickly and unsuccessfully. This rapid passage increases motility in the small intestine as well as the person’s osmotic pressure.Due to the increased osmotic pressure, blood flow slows down, significant vasodilation occurs, and intercellular function in blood plasma is impaired. The small intestine secretes histamine, serotonin, and quinine to correct these conditions. These secretions cause the intestinal wall of the small intestine to stretch.Early dumping syndrome usually has some symptoms including vomiting, weakness, abdominal cramping, and nausea.

Late Dumping Syndrome

Late dumping syndrome is the syndrome that usually occurs after consuming food and drinking. Here, food (especially overconsumption or unsuitable food) reaches your duodenum quickly after digestion. In this case, your blood sugar starts to rise.Late symptoms usually appear within 1 to 3 hours or at least 45 minutes after meals. It causes trembling, hunger, concentration disorder, dizziness, and confusion.

Dumping Syndrome Levels

Dumping syndrome can develop in 3 different levels:Mildly Effective: In this type, the person only experiences increased heart rate and fatigue. It usually disappears within a short time. It does not seriously affect a person’s life.Moderate: Sharp deterioration in perception, increased heart rate, bloating, intense weakness, irritability, and emotional lability are seen at this level. The effect diminishes when the person lies down.High level: This type of dumping can occur in a mixed manner as a semato-adreal and a vigo-insular crisis.

Dumping Syndrome Symptoms

Dumping syndrome symptoms may develop as follows:- The suffering patient experiences a feeling of fullness in their stomach;- They feel a heat radiating upwards from the stomach;- Excessive sweating may occur and tremors begin;- A feeling of general weakness, accompanied by tinnitus, drowsiness, dizziness and trembling of the limbs, even blurred vision occurs;- Heart rate and breathing rate slows down;- The person feels a constant urge to urinate;- The worsening headache may spread.- In the progression of these symptoms, people may experience conditions such as diarrhea, stomach growling (rumbling), and memory loss.

Sugar, Diarrhea Dumping Syndrome

The main reason for encountering this complication is the consumption of sugary food or things other than your diet. Since the stomach is smaller than before and connects directly to the small intestine, excessive amounts of food or indigestible eatables are absorbed directly. In this case, a rapid increase in blood sugar levels occurs.Dumping syndrome occurs, especially with diarrhea. Abdominal pain or burning that starts in people progresses to diarrhea.

Dumping Syndrome Hypoglycemia

Hypoglycemia is one of the severe symptoms seen in dumping syndrome. It occurs as an exaggerated response to glucose absorption in the small intestine, especially when the carbohydrate load is rapidly discharged.Early symptoms of dumping syndrome hypoglycemia may include bloating, abdominal pain, nausea, vomiting, tachycardia, flushing, and hypertension (high blood pressure).

Dumping Syndrome Diagnosis

Based on a study published by the US National Library of Medicine if patients have more than one of the dumping syndrome symptoms (both late and early), the doctor should suspect the presence of this post-weight loss surgery complication.Oral glucose tolerance test is one of the most effective methods in diagnosing dumping syndrome considering the blood glucose level. Even if the results showed no sign of dumping syndrome, it’d better take continuous glucose monitoring tests for some time after the surgery.Glycemia measurements can also be used to measure the blood sugar level. Some doctors also prepare questionnaires based on dumping syndrome symptoms, by filling which your doctor will have the necessary information for the right diagnosis.Moreover, it is vital to constantly check hormone insulin levels in your blood as an excessive amount of it, especially after eating is very dangerous.So, in case you feel any discomfort, your doctor can easily recognize whether you have this complication or not in order to prescribe the right treatment.
