The treatment of diarrhoea in pregnant women is mainly based on the severity of the diarrhoea.
If the diarrhoea is mild, it can usually be cured mainly by dietary adjustments, eating well-digested, less fibrous fluids and soups, and paying attention to dietary hygiene.
If the diarrhoea is severe, you should seek medical examination to determine if there is a bacterial or viral infection; if there is dehydration, you should be treated with fluids to correct the water-electrolyte imbalance, as diarrhoea is more severe and can cause loss of body water as well as inadequate supply of nutrients, which can cause shock in severe cases.
