  • Causes
  • Home Care
    • You may take the following steps:

      • Avoid chewing gum or carbonated drinks. Stay away from foods with high levels of fructose or sorbitol.
      • Avoid foods that can produce gas, such as Brussels sprouts, turnips, cabbage, beans, and lentils.
      • Do not eat too quickly.
      • Stop smoking.

      Get treatment for constipation if you have it. However, fiber supplements such as psyllium or 100% bran can make your symptoms worse.

      You may try simethicone and other medicines you buy at the drugstore to help with gas. Charcoal caps can also help.

      Watch for foods that trigger your bloating so you can start to avoid those foods. These may include:

      • Milk and other dairy products that contain lactose
      • Certain carbohydrates that contain fructose, known as FODMAPs
  • When to Contact a Medical Professional
    • Call your health care provider if you have:

      • Abdominal pain
      • Blood in the stools or dark, tarry looking stools
      • Diarrhea
      • Heartburn that is getting worse
      • Vomiting
      • Weight loss
