A disease that killed a lot of soldiers was dysentery, as well as typhoid, malaria and even the Spanish Flu.
Trench Fever and even pneumonia killed lots of soldiers.
These diseases have killed more soldiers than combat related injuries.
Dysentery was a major killer of soldiers in the Mexican War between the years of 1846 and 1848 as nearly 13 percent of the entire United States force perished or died from Dysentery and 88 percent of the deaths were a result of infectious diseases which overwhelmed dysentery.
During the American Civil War, typhoid fever was also a major cause of death in soldiers along with pneumonia, diarrhea, dysentery as well as malaria.
Malaria was a significant problem in the Civil War as well as other conflicts and most particularly in areas with marshes and swamps.
The 1918 Spanish Flu pandemic, struck an estimated 500 million people and killed an estimated 50 million people worldwide and around 45,000 American Soldiers.
And during World War I, trench fever, which is a debilitating disease transmitted by lice, caused significant hardship and incapacitated many solders.
Another condition which affected soldiers was Da Costa's syndrome which was initially described in soldiers during the American Civil War and got the term Soldier's Heart which causes symptoms such as chest pain, heart palpitations, shortness of breath, dizziness and fatigue which can be exacerbated by physical exertion.
Da Costa's syndrome is often linked to periods of intense physical and psychological stress, like wartime experiences or prolonged periods of high pressure work.
And in some cases Da Costa's syndrome has been associated with previous illnesses or infections which suggests a possible link to your body's response to these events.
Da Costa's syndrome is not PTSD although it does share some of the same features with modern PTSD.
However Da Costa's syndrome is not the same diagnoses as PTSD and Da Costa's syndrome is not considered to be a historical term.
The symptoms of soldier's heart also known as Da Costa's syndrome include shortness of breath, fatigue upon exertion, palpitations, sweating, chest pain and even sometimes orthostatic intolerance.
The soldier's heart condition is also known as Da Costa Syndrome and is a syndrome that had symptoms similar to those of heart disease.
The symptoms of Da Costa Syndrome are sweating and chest pain, palpitations, shortness of breath and fatigue which is often triggered by stress or exertion.
Da Costa's syndrome is also called soldier's heart or neurocirculatory asthenia.
The syndrome Da Costa's syndrome was a syndrome or a set of symptoms that are similar to the symptoms of heart disease.
The symptoms include shortness of breath, fatigue upon exertion, palpitations, sweating, chest pain and even sometimes orthostatic intolerance.
Palpitations are also known as heart palpitations and is a feeling of a rapid, fluttering or pounding heartbeat.
Chest pain and discomfort which is a sensation of tightness, pressure or pain in the chest which can be exercise related and a rapid heart rate or abnormally fast heartbeat as well as difficulty breathing, especially during or after exertion and smothering sensations which is a feeling of not getting enough air are common symptoms of Da Costa Syndrome.
Someone with Da Costa Syndrome may also feel unusually tired even after minimal exertion and experience excessive sweating, especially during or even after exertion and they may feel lightheaded or feel like they may pass out and may experience anxiety or a feeling of being on the edge.
Other symptoms of Da Costa Syndrome that you may experience are a sensation of needing to take in more air than normal, feeling lightheaded or dizzy when standing up suddenly and digestive issues as well as difficulty in falling asleep or staying asleep.
The term "Soldier's Heart" also known as Da Costa Syndrome, was first coined in the post-Civil War era when people were looking at these veterans returning from Civil War combat and trying to understand why they had been changed, because there was general recognition that they had been changed, and that many of those changes were not for the good.
