Interstitial lung disease (in-tur-STISH-ul) describes a large group of diseases, most of which cause progressive scarring of the lung tissue. The scars associated with interstitial lung disease ultimately affect your ability to breathe and get enough oxygen into your bloodstream.
Interstitial lung disease can be caused by long-term exposure to hazardous substances such as asbestos. Certain types of autoimmune diseases like rheumatoid arthritis can also cause interstitial lung disease. However, in some cases the causes remain unknown.

The main signs and symptoms of interstitial lung disease are:
- Shortness of breath at rest or worse with exertion
- Dry cough

Interstitial lung disease appears to occur when a lung injury triggers an abnormal healing response. Usually, your body makes just the right amount of tissue to repair the damage. In the case of interstitial lung diseases, however, the repair process goes wrong and the tissue around the air sacs (alveoli) becomes scarred and thickened. This makes it harder for oxygen to get through your bloodstream. Interstitial lung disease Treatment in Hyderabad
Factors that can make you more prone to interstitial lung disease include:
- Age. Interstitial lung disease affects adults much more often, although infants and children sometimes develop the disease.
- Exposure to occupational and environmental toxins. If you work in mining, agriculture, construction, or are exposed for any reason to pollutants known to damage your lungs, your risk of developing interstitial lung disease increases.
- Gastroesophageal reflux. If you have acid reflux or uncontrolled indigestion, you may be at increased risk of interstitial lung disease.
- Smoke. Some forms of interstitial lung disease are more common in people with a history of smoking, and active smoking can make the condition worse, especially if there is emphysema.
- Radiation and chemotherapy. Breast radiation therapy or the use of certain chemotherapy drugs increase the risk of developing lung disease.
Interstitial lung disease can cause a number of life-threatening complications, including:
- Pulmonary arterial hypertension (pulmonary hypertension). Unlike systemic high blood pressure, this condition only affects the arteries in your lungs. It starts when scar tissue or low oxygen levels restrict smaller blood vessels and restrict blood flow to your lungs. This in turn increases the pressure in the pulmonary arteries. Pulmonary hypertension is a serious disease that is getting worse and worse.
- Right heart failure (cor pulmonale). This serious condition occurs when the lower right chamber of the heart (right ventricle) – which is less muscular than the left – has to pump harder than usual to move blood through clogged pulmonary arteries. Eventually, the right ventricle fails due to the added stress. This is often a consequence of pulmonary hypertension.
- Apnea. In the end-stage of chronic interstitial lung disease, respiratory failure occurs when very low blood oxygen levels, along with increasing pressure in the pulmonary arteries and right ventricle, cause heart failure. Interstitial lung disease Treatment in Hyderabad
