Causes of Bloating
Bloating is a feeling of fullness or tightness around your belly. You might feel like you need to pass gas. In some cases, your belly might appear swollen (distension).
You could have bloating because of:
- Foods like beans, cabbage, broccoli, or fizzy drinks
- Drinking and eating too fast
- Food intolerances, like gluten or lactose
- Drugs like aspirin, opioids, or corticosteroids
- Irritable bowel syndrome (IBS), Crohn's disease, or ulcerative colitis
In some cases, bloating could be a symptom of ovarian cancer. The reason you may bloat with this type of cancer is because of a buildup of fluid inside the abdomen (belly), called ascites. This can happen because of things such as:
Cancer spreads to the peritoneum. If cancer reaches your peritoneum, the membrane that lines the inside of the abdomen and the organs within, it may irritate it. This causes the peritoneum to make more fluid than normal.
Cancer spreads to the liver. Ovarian cancer can affect your liver or the vein that moves blood to your liver. If this happens, the blood pressure in the portal vein that travels through your liver can go up. Higher pressure in this vein could cause fluid to collect inside the abdomen.
Blockage of the lymphatic system. If ovarian cancer blocks your lymphatic system, the part of your immune system that moves lymph fluid back into your bloodstream, the fluid will not drain correctly and may collect inside the abdomen.
Other Symptoms of Ovarian Cancer
Be on the lookout for other signs of ovarian cancer besides bloating, such as:
These symptoms may not mean you have cancer. Most of the time, they happen because of another condition. But if you notice them more often, make an appointment with your doctor.
Also, see your doctor if you have bloating for 3 weeks or longer.
