Some common causes of tummy bloating include indigestion, gas, lactose intolerance and constipation, according to Healthline. Serious medical conditions can also lead to tummy bloating, which include celiac disease, pancreatic insufficiency and ovarian cancer.
Celiac disease is an autoimmune disorder that makes it difficult for the body to absorb certain nutrients, such as calcium and folate, notes WebMD. In addition to abdominal bloating, symptoms of the disease include a severe skin rash, iron-deficiency anemia and a tingling sensation in the legs. Celiac disease is caused by the body forming antibodies to gluten, which attack the intestinal lining and damage it.
Pancreatic insufficiency occurs when the pancreas does not make enough enzymes to digest food, explains WebMD. The disease impairs the body's ability to digest fats, starches and proteins, which causes symptoms such as gas and fatty stools. Pancreatic insufficiency can be caused by chronic pancreatitis, surgery and inherited diseases such as cystic fibrosis and Shwachman-Diamond syndrome.
Ovarian cancer may not present many symptoms, especially at an early stage, according to Mayo Clinic. Symptoms of ovarian cancer include weigh loss, pelvic discomfort, changes in bowel habits and frequent urination. There is no known cause for ovarian cancer, which commonly begins in the tissue that covers the ovaries. Other ovarian cancers begin in hormone- or egg-producing cells in the ovarian tissue.
