Cystic Fibrosis

The book describes cystic fibrosis as a genetic condition affecting the exocrine glands, leading to the production of thick and sticky mucus that blocks airways and disrupts digestion. It explains how this disorder is inherited, the role of mutations in the CFTR gene, and why the disease cannot be prevented.

Readers will learn about common symptoms such as salty-tasting skin, persistent cough with phlegm, shortness of breath, wheezing, greasy stools, sinusitis, constipation, jaundice, nasal polyps, and nail clubbing. Complications including lung infections, respiratory failure, pancreatitis, bowel obstruction, infertility, osteoporosis, pulmonary hypertension, and cirrhosis are also discussed.

Diagnostic methods such as sweat testing, sputum analysis, imaging scans, pulmonary function tests, and genetic testing are described, along with treatments including chest physical therapy, antibiotics, bronchodilators, mucolytics, vitamin supplements, and hydration.

This book will interest students, healthcare workers, and readers who want to learn about cystic fibrosis, its risks, and available treatments.
