Bloating occurs when intestinal gas accumulates, causing the abdomen to become distended and uncomfortable. Most commonly caused by the inability to digest a certain food, bloating may also be indicative of a more serious disorder like Irritable bowel syndrome or Ulcerative colitis.
Some people develop an "intolerance" to certain foods (like lactose, for example) when they have a deficiency of the enzyme needed to digest the substance. A food intolerance often results in bloating.
Bloated heavy feeling in stomach.
