Are the symptoms of acute gastroenteritis serious? Can it be used as a reason for asking for leave? Will my mother be worried about this?

Hello, the symptoms of acute gastroenteritis may or may not be serious. Usually, food poisoning is acute gastritis or gastroenteritis, with different symptoms, such as discomfort and pain in the upper and middle abdomen, and even abdominal cramps, anorexia, nausea, vomiting and diarrhea in severe cases. In severe cases, acid-base poisoning and even shock may be caused by imbalance of water and electrolyte. It can generally be used as a reason for taking time off.
