Hello Thank you for your query. Dysentery during pregnancy is serious. There could be various causes like amebic dysentery, bacterial infection etc. you cannot just take any medicine off the net for this, particularly during pregnancy. Please consult your primary care physician if not the specialist, and go for stool examination and necessary tests. After this, you need to take appropriate medications. Meanwhile, you can take Sporolac tablets. Take light, bland diet, mostly liquids. Avoid eating outside. Avoid dehydration as it will affect the fetus. Take care
