Peritoneal mesothelioma can cause several symptoms and complications related to the gastrointestinal tract, including constipation, nausea, and vomiting. These are caused by the cancer itself and by tumors growing in the abdomen but also by treatments. Management is important for improving quality of life.
Gastrointestinal Symptoms Caused by Peritoneal Mesothelioma
Because the cancer grows primarily in the abdomen, gastrointestinal symptoms and complications are common with this type of cancer and may include:[1]

What Causes GI Symptoms?
Most often, the GI symptoms associated with peritoneal mesothelioma are directly caused by the tumors in the abdomen. However, sometimes the treatments used to manage, treat, or cure the cancer.
Complications Caused by the Cancer
Tumors growing in the abdominal cavity cause GI distress by pushing on digestive organs, nerves, and other tissue. The cancer can also causes ascites, the buildup of fluid in the abdomen, which can also cause the complications.
Constipation is a common symptom, for instance, and it is usually caused by a tumor pressing on or infiltrating the bowels. Rarely, and in extreme cases, the tumor can cause a complete bowel obstruction, which is painful and dangerous. This may require medical interventions at the hospital or urgent surgery in the most serious cases.
Complications from Cytoreductive Surgery
The most effective treatment for peritoneal mesothelioma is cytoreductive surgery followed by HIPEC. The surgery removes as much cancerous tissue from the abdomen as possible. The HIPEC is a type of chemotherapy that circulates the drugs directly in the abdomen instead of intravenously throughout the whole body.[2]
While this treatment can be highly effective, even curative, there are always risks. Complications from the surgery can lead to significant GI issues:[2]
- Bowel obstruction
- Prolonged ileus
- Infections
- Fistula
- Pain
- Nausea/ vomiting
- Pneumonia and other pulmonary complications
- Lowered immune system (neutropenia)
- Blood clots
- Organ dysfunction or failure
Side Effects of Chemotherapy
HIPEC causes fewer side effects than standard, intravenous chemotherapy. However, it can still cause side effects, and patients who are not candidates for HIPEC may receive traditional chemotherapy and struggle with GI side effects:[3]
- Nausea
- Vomiting
- Diarrhea
- Constipation
Managing GI Complications in Peritoneal Mesothelioma
GI problems can have a significantly negative impact on quality of life, and even lead to social isolation. The sometimes-embarrassing side effects may lead a patient to stay home and to be afraid to be around other people. Addressing and managing the complications is important for health and quality of life.
Bowel Obstruction
A bowel obstruction is the most serious GI complication, and if not addressed immediately can lead to tissue death in the intestines and more serious complications. It is essential to contact your doctor if you have any signs of obstruction: cramps, constipation, swelling, and inability to have a bowel movement or pass gas.[4]
When bowel obstruction is caused by a tumor, surgery to remove it may be necessary. If the obstruction is only partial, changes in diet and removal of fluid or air from the abdominal cavity or intestines can help. In some cases, a stent place in the bowels to expand them will also be used.[4]
Bloating and Pain
Bloating and pain in peritoneal mesothelioma are often caused by ascites, the buildup of fluid in the abdominal cavity. This is usually managed with a paracentesis, a procedure used to drain fluid. If the fluid keeps returning, the patient may receive a catheter. This is a semi-permanent tube that drains fluid into a bag. Patients can manage it at home.
Constipation
In addition to treating the cancer to relieve constipation, several other strategies can be useful:[5]
- Over-the-counter medications and laxatives
- Drinking plenty of fluids and staying hydrated
- Eating more fiber
- Being physically active, to the extent possible
- Prescribed medications for constipation
Nausea and Vomiting
Nausea and vomiting can be triggered by both the cancer and its treatments. These symptoms are uncomfortable, but they can also lead to harmful weight loss, so management is important:[6]
- Medications, including over-the-counter and prescription drugs
- Medical cannabis
- Complementary and alternative practices, such as acupuncture, biofeedback, and hypnosis
- Changing diet to include foods that are appealing or bland to reduce nausea
- Staying hydrated with small amounts of liquid and ice chips
The GI symptoms and complications triggered by peritoneal mesothelioma can be uncomfortable, painful, embarrassing, and dangerous. It is essential that patients talk to their medical teams about these issues so they can make a plan for treatment or management.
