==Causes==
Causes of hiatus hernia vary depending on each individual. Among the multiple causes, however, are the mechanical causes which include: improper heavy weight lifting, hard [[coughing]] bouts, sharp blows to the abdomen, and incorrect [[Human position|posture]].<ref>{{cite web|url=http://inguinalhernia.us/hiatal-hernia-causes.html| title=Hiatal Hernia Symptoms, Causes And Relation To Acid Reflux And Heartburn|access-date=2010-05-24 |archive-date=October 28, 2008 |archive-url= https://web.archive.org/web/20081028010841/http://www.inguinalhernia.us/hiatal-hernia-causes.html }}</ref>

Furthermore, conditions that increase the pressure of the abdominal cavity may also cause hernias or worsen the existing ones. Some examples would be: obesity, straining during a bowel movement or urination (constipation, [[enlarged prostate]]), [[chronic obstructive pulmonary disease|chronic lung disease]], and also, fluid in the abdominal cavity ([[ascites]]).<ref>{{cite web | vauthors =  Balentine JR | veditors = Stöppler MC | date = | work = eMedicineHealth.com | publisher = WebMD |url= http://www.emedicinehealth.com/hernia/page2_em.htm |title=Hernia Causes |access-date=2010-05-24 |url-status=live |archive-url =https://web.archive.org/web/20100531073222/http://www.emedicinehealth.com/hernia/page2_em.htm |archive-date=2010-05-31}}</ref>

Also, if muscles are weakened due to [[poor nutrition]], [[smoking]], and [[overexertion]], hernias are more likely to occur.

The physiological school of thought contends that in the case of [[inguinal hernia]], the above-mentioned are only an [[anatomical]] symptom of the underlying [[physiological]] cause. They contend that the risk of hernia is due to a physiological difference between patients who have hernia and those who do not, namely the presence of [[aponeurotic]] extensions from the [[transversus abdominis]] aponeurotic arch.<ref>{{cite journal | vauthors = Desarda MP | title = Surgical physiology of inguinal hernia repair--a study of 200 cases | journal = BMC Surgery | volume = 3 | pages = 2 | date = April 2003 | pmid = 12697071 | pmc = 155644 | doi = 10.1186/1471-2482-3-2 | doi-access = free }}</ref> There isn't any proof that being physically active will cause a hernia to get stuck or make an existing hernia worse.<ref>{{Cite journal |last1=Montgomery |first1=John |last2=Dimick |first2=Justin B. |last3=Telem |first3=Dana A. |date=2018-09-11 |title=Management of Groin Hernias in Adults-2018 |url=https://pubmed.ncbi.nlm.nih.gov/30128503/ |journal=JAMA |volume=320 |issue=10 |pages=1029–1030 |doi=10.1001/jama.2018.10680 |issn=1538-3598 |pmid=30128503|s2cid=205095374 }}</ref>

Abdominal wall hernia may occur due to trauma. If this type of hernia is due to blunt trauma it is an emergency condition and could be associated with various solid organs and hollow viscus injuries.
