Dumping syndrome symptoms

The clinical presentation of dumping syndrome can divide into early and late symptoms. Early symptoms are subdividing into GI symptoms and vasomotor symptoms.

Symptoms of dumping syndrome

The dumping syndrome symptoms often divide into "early" and "late" symptoms. The early symptoms begin during or immediately after a meal. The early dumping syndromes are mostly gastrointestinal and vasomotor symptoms.

Gastrointestinal symptoms of dumping syndrome

The gastrointestinal symptoms include:

  • Nausea,
  • Vomiting,
  • Bloating,
  • Abdominal cramping,
  • Diarrhea,
  • Dizziness, and
  • Fatigue.

Vasomotor or systemic symptoms of dumping syndrome

The vasomotor or systemic symptoms include:

  • Diaphoresis,
  • Desire to lie down,
  • Headache,
  • Flushing,
  • Fatigue,
  • Lightheadedness,
  • Pallor,
  • Palpitations, and
  • Syncope.

Late dumping symptoms begin from one to three hours after eating. This is due to the dumping of large quantities of sugars (hyperglycemia) into the small intestine. The body is responding by releasing large amounts of insulin to absorb the sugars, leading to low levels of sugar (hypoglycemia) in the body. This includes:

  • Tremor,
  • Sweating,
  • Hunger,
  • Difficulty with concentration,
  • Decrease concentration,
  • Dizziness and
  • Fainting.

People with dumping syndrome often have both types of symptoms.

A study shows about two-thirds people have early symptoms, and about one-third has late symptoms of dumping syndrome. Some people experience both the symptoms. No matter, when is the problematic symptom developing? However, they may be worse following a high-sugar meal, particularly one that is rich in sucrose (table sugar) or fructose (fruit sugar).
