Gastrointestinal stromal tumors (GISTs) can vary widely in terms of symptoms, depending on their size, location, and whether they cause any complications. However, some common symptoms of GISTs may include:
- Abdominal Pain or Discomfort: This is one of the most common symptoms associated with Gastrointestinal stromal tumors. The pain may be localized to a specific area or may be more generalized.
- Gastrointestinal Bleeding: GISTs can cause bleeding in the digestive tract, which may result in symptoms such as bloody or black stools, or vomiting blood (hematemesis).
- Feeling of Fullness or Early Satiety: Some individuals with GISTs may experience a sensation of fullness or discomfort in the abdomen even after consuming small amounts of food.
- Nausea and Vomiting: Gastrointestinal stromal tumors symptoms located in the stomach or small intestine may lead to nausea and vomiting, particularly if they obstruct the digestive tract or cause irritation.
- Palpable Mass: In some cases, particularly if the tumor is large, a palpable mass may be felt in the abdomen during physical examination.
- Fatigue: Chronic bleeding from a GIST can lead to iron deficiency anemia, which may cause fatigue and weakness.
- Weight Loss: Unexplained weight loss may occur in individuals with GISTs, particularly if they experience symptoms such as abdominal pain, early satiety, or difficulty eating.
It’s important to note that some GISTs may be asymptomatic and only discovered incidentally during imaging tests performed for other reasons. Additionally, GISTs can sometimes cause complications such as bowel obstruction or perforation, which may lead to more severe symptoms such as severe abdominal pain, fever, and signs of peritonitis.
