Complications of Gastric (Stomach) Cancer

Overview

Gastric cancer, also known as stomach cancer, can lead to various complications that can affect a person's health and quality of life. Some common complications of gastric cancer include:

• Weight loss: Gastric cancer can cause unintentional weight loss due to decreased appetite, difficulty eating, or malabsorption of nutrients. It is important to maintain a healthy weight for overall well-being. If weight loss occurs, working with a healthcare team, including a registered dietitian, can help develop a personalized nutrition plan to support weight maintenance or gain.
• Anemia: Anemia is a condition characterized by a low red blood cell count or low levels of hemoglobin in the blood. It can result from chronic bleeding associated with gastric cancer or nutritional deficiencies. Treatment may involve iron supplementation or blood transfusions to restore healthy levels of red blood cells.

• Surgical complications: Surgery is a common treatment for gastric cancer, but it can be associated with complications such as infection, bleeding, leakage at the surgical site (anastomotic leakage), or bowel obstruction (ileus). These complications require prompt medical attention and may necessitate additional interventions or treatments.

• Dumping syndrome: This condition can develop after surgery when all or parts of the stomach is removed. This occurs when food moves too quickly from the stomach into the small intestine. It can cause symptoms like nausea, vomiting, bloating, diarrhea, and dizziness. To prevent dumping syndrome, it is important to eat small, frequent meals and avoid high-sugar and high-fat foods. Medications may also be prescribed to help manage symptoms.
• Nutritional deficiencies: After gastrectomy surgery (removal of part or all of the stomach), patients may experience difficulties absorbing nutrients from food. This can lead to deficiencies in vitamins and minerals, such as iron and vitamin B12. To prevent nutritional deficiencies, doctors may recommend dietary changes or supplements to ensure adequate intake of essential nutrients.

To prevent complications related to gastric cancer or manage them if they occur:

• Follow your doctor's recommendations: It is crucial to adhere to the treatment plan prescribed by your healthcare team. This may include surgery, chemotherapy, radiation therapy, or other treatments.
• Maintain a healthy diet: Eating a balanced diet that includes fruits, vegetables, whole grains, lean proteins, and healthy fats can support overall health and aid in recovery after surgery.
• Stay hydrated: Drinking enough fluids is important for digestion and overall well-being.
• Attend regular follow-up appointments: Regular check-ups with your healthcare team are essential for monitoring your condition and addressing any potential complications early on.
• Seek support: Coping with gastric cancer and its complications can be challenging both physically and emotionally. Reach out to support groups or counseling services to connect with others who have experienced similar situations.

Remember that each person's journey with gastric cancer is unique, so it's important to consult with your healthcare provider for personalized advice and guidance regarding prevention and treatment of complications associated with gastric cancer.
