3. Gastritis
An episode of gastritis can cause the lining of the stomach to become very swollen and subsequently, extremely painful for the affected person. Acute episodes of gastritis are not usually anything to worry too much about, as they occur over the short term, most commonly as the result of a bacterial infection.
Once the infection has run its course, gastritis finishes up with almost as much haste as it came about in the first place. There are however a number of conditions which can cause gastritis to tip over from the manageable acute stage to the more unbearable chronic type. These underlying illnesses and conditions include Crohn’s disease and some autoimmune diseases, as well as sarcoidosis and various allergies.
Some viruses can also cause gastritis to become chronic. As you might imagine, the pain felt during an episode of chronic gastritis is at least twice as bad as an episode of acute gastritis.
