According to Lowe and Bennett (2003), post-traumatic stress disorder is an acute anxiety disorder caused by witnessing distressful events such as terrorist attacks, tragic road accidents, rape and violent death. The affected may experience flashbacks and nightmares as ways of relieving himself or herself from the stress. He or she often suffers from isolation, inability to fall asleep and always get easily irritated. Other health problems that stem from stress include heart disease, asthma and diabetes.
A study conducted by Bickerstaff (2007) found out that those who have stress are more vulnerable to heart problems and high blood pressure. He argues that stress increases heart-beat rate and hence higher rate of blood flow. This results into high blood pressure which can lead to cardiac problems like heart attack.
Stress causes asthma most likely in kids. A survey conducted by Gould (2000) indicates that kids with stressed out parents are at a higher risk of developing asthma. It also revealed that most mothers who drink and smoke during their pregnancy period often give birth to asthmatic babies.
Stress causes diabetes in two ways, first, it makes one indulge in unhealthy behaviors such as excessive drinking as a way of evading stress. This results into increased sugar level in his or her blood making him or her more susceptible to diabetes. Secondly, stress increases the glucose level in the blood resulting to diabetes (Cockerham, 2004).
Since there are evidences of post-traumatic stress disorder, I agree with the strength of the linkage between stress and the cited diseases. This is because most of the people who suffer from these health problems if evaluated clearly indicates that they are stressed up.
