Causes of running stomach

 
Several conditions can cause diarrhoea or running stomach. The commonest causes are infection or food poisoning. Food poisoning is caused due to pre-existing toxins in the food you have eaten. There is no infection. It will recover without active management and the symptoms can usually be controlled by drinking adequate amounts of fluids. If the vomiting caused by food poisoning is severe, you may need to be given IV fluids. Infective diarrhoea will require further management in addition to fluid replacement, depending upon the type of infection. Some infections may require antibiotics. There are other conditions that can also cause diarrhoea including autoimmune conditions, irritable bowel syndrome, or plain and simple anxiety.
