Can other illnesses cause PH?

In many patients, PH can be associated with a number of other medical conditions:

  • Connective tissue diseases, such as scleroderma (also known as CREST), or systemic lupus erythematosus (SLE)
  • Infection with HIV, the AIDS virus
  • Severe liver disease, such as cirrhosis
  • Diseases of the blood, like sickle-cell disease and thalassemia
  • History of taking certain appetite-suppressant medications for weight loss (known as anorexigens)
