Fibrosis is a condition that is characterized by the formation of scar tissue that results either from an injury or from a long-standing inflammation. Physicians have classified fibrosis into two main types – pulmonary fibrosis and cystic fibrosis.
Pulmonary fibrosis refers to the hardening, scarring and overgrowth of lung tissues because of too much collagen. One of the most common types of this kind of disease is idiopathic pulmonary fibrosis. What this means is that it is a fibrosis disease that has an unknown cause. Some of the symptoms of this kind of disease include chronic dry cough, difficulty breathing, fatigue, general malaise, discomfort in the chest area, loss of appetite, and a drastic loss in weight. This disease usually happens in people from the ages of 40 to 70. Both men and women suffer equally from this disease. There is poor prognosis for those who suffer from pulmonary fibrosis. The average life expectancy is from 4 to 6 years after the diagnosis.
The other type of fibrosis is cystic fibrosis. This is a chronic and fatal disease and generally considered fatal. This disease attacks the mucus glands and the symptoms would include malnutrition, abnormal beating of the heart, respiratory infections, and difficulty in breathing. It also leads to other medical complications like nasal polyps, hemoptysis, rectal prolapsed and sinusitis. Cystic fibrosis affects both the respiratory and digestive systems and this disease can be found not only in adults but also children and young adults. Usually, the symptoms of cystic fibrosis will already be felt after birth. It is rare for symptoms to only appear when children have grown into adolescence.
