As a woman with no medical training, I found this book to be very thorough and comprehensible. Dr. Han gives an intensely detailed description of multiple common medical conditions related to the lung. 5/5 stars!
- "The beginnings of the lungs are first detectable around week 3 in the human embryo. This is known as the embryonic period. By week 5, two lung buds are evident. By week 8, the lung lobes begin to form, and by week 16, the airways complete their seemingly infinite branching. Between weeks 16 and 25 is when the alveoli, our gas exchange units, begin to form. Amniotic fluid is essential for normal lung development at this stage. In the womb, the fetus 'breathes' amniotic fluid, which mechanically stretches the developing lung. Very low levels of amniotic fluid can disrupt fetal lung growth. It is not around week 20 of gestation that the alveolar cells begin to manufacture surfactant, a substance crucial for proper lung function and lung defense. However, the fully formed alveoli in their adult configuration are not present until roughy 5 weeks [i/] after [/i] delivery and the alveoli continue to subdivide after birth. Recent data may suggest that alveoli may continue to develop during childhood and adolescence." (p.59)
- "Vitamin D helps to maintain immune function and plays a role in lung development... To many, there seem to be more and more children with allergies of all kinds than there used to be. The types of bacteria that children are exposed to early in life may play a role. The 'hygene hypothesis' was originally generated as a potential explanation for why children raised in West Germany were found to have significantly higher rates of asthma than those raised in Communist Eat Germany, despite higher air pollution in the east. Children who lived on farms in particular had lower rates of asthma and allergic diseases... For instance, long-term exposure to animal stables until the age of 5 has been associated with very low rates of asthma. While there is no clear link to personal cleanliness and allergic diseases, it may be that early exposures to a wide variety of microbes blunts the arm of the immune system responsible for allergic reactions. Incidentally, there is currently no strong evidence to suggest that probiotics reduce development or severity of allergic diseases." (p.67-68)
- "An often overlooked source of indoor air pollution is residential wood-burning stoves. Solid fuels, including wood and coal used for cooking and heating in developing countries, are known to cause significant lung damage and predispose women and children, in particular, to the development of COPD." (p.71)
- "We also have ways of forcing air into the lungs using 'non-invasive' equipment that involves a mask being strapped to a patient's face and air being blown into the lungs. This is referred to as [/i] non-invasive ventilation (NIV).[i/]
I would recommend this book to anyone without deep knowledge of the medical world who is interested in learning more about the lungs. I would not recommend this book to anyone who does have a deeper knowledge of the medical world. You would likely find this book too basic and perhaps a bit boring, because you may feel it does not delve deeply enough into detail.
