Inflamed nasal passages or a stuffy nose Digestive signs and symptoms The thick mucus can also block tubes that carry digestive enzymes from your pancreas to your small intestine. Without these digestive enzymes, your intestines aren't able to completely absorb the nutrients in the food you eat.

The result is often: Foul-smelling, greasy stools Poor weight gain and growth Intestinal blockage, particularly in newborns meconium ileus Severe constipation Frequent straining while passing stool can cause part of the rectum — the end of the large intestine — to protrude outside the anus rectal prolapse.

When this occurs in children, it may be a sign of cystic fibrosis. Parents should consult a physician knowledgeable about cystic fibrosis. Rectal prolapse in children may sometimes require surgery.

Rectal prolapse in children with cystic fibrosis is less common than it was in the past, which may be due to earlier testing, diagnosis and treatment of cystic fibrosis.

When to see a doctor If you or your child has symptoms of cystic fibrosis — or if someone in your family has cystic fibrosis — talk with your doctor about testing for the disease.

Seek immediate medical care if you or your child has difficulty breathing. Request an Appointment at Mayo Clinic Causes In cystic fibrosis, a defect mutation in a gene changes a protein that regulates the movement of salt in and out of cells.

The result is thick, sticky mucus in the respiratory, digestive and reproductive systems, as well as increased salt in sweat.

Many different defects can occur in the gene. The type of gene mutation is associated with the severity of the condition. Children need to inherit one copy of the gene from each parent in order to have the disease. If children inherit only one copy, they won't develop cystic fibrosis. However, they will be carriers and possibly pass the gene to their own children.

Risk factors Family history. Because cystic fibrosis is an inherited disorder, it runs in families. Although cystic fibrosis occurs in all races, it is most common in white people of Northern European ancestry. Complications Respiratory system complications Damaged airways bronchiectasis.

Cystic fibrosis is one of the leading causes of bronchiectasis, a condition that damages the airways. This makes it harder to move air in and out of the lungs and clear mucus from the airways bronchial tubes. Thick mucus in the lungs and sinuses provides an ideal breeding ground for bacteria and fungi.Sucrose, table sugar, is formed by joining glucose and fructose.

Sucrose is the major transport form of sugars in plants. Lactose, milk sugar, is formed by joining glucose and galactose. Phospholipids are major components of cell membranes.
