  • Cystic Fibrosis
    • What is Cystic Fibrosis?
      • It's a genetic disorder.
      • It affects many organs of the body, particularly the lungs and pancreas.
      • The organs become clogged up by thick, sticky mucus which stops them from working properly.
      • The reproductive system is also affected so many people with CF are infertile.
    • What are The Symptoms?
      • Persistent coughing caused by the body trying to get rid of the mucus.
      • reoccurring chest and lung infections as the mucus build-up is a breeding ground for bacteria.
      • Malnutrition from the body not digesting enough vital nutrients.
      • Diabetes
      • Sinusitis
      • Arthritic-like swelling in some big joints (e.g. the knee)
    • What is a carrier?
      • A carrier is someone who have a dominant healthy allele.
      • Their bodies work normally.
      • They also carry a recessive CF gene, which shows no symptoms.
      • Because they don't show any symptoms, they don't know that they are carrying it.
      • If they have a child with someone who also has a recessive CF gene, there is a 25% chance that the child will have CF.
    • How is it treated?
      • Treatment for CF includes physiotherapy and antibiotics.
      • These help keep the lungs clear of mucus and infections
      • Enzymes are used to replace the ones that the pancreas can't produce and to thin the mucus.
      • There is still no cure.
