Constipation are characterized by irregular and infrequent bowel movement where as diarrhea are usually liquid bowel movement. Constipation is the result of insignificant diet and lack of physical work, also due to narcotics, drugs, therapeutic drug, and change in environment. In order to get relief from constipation eat roughage, lots of fiber, fresh fruit, lots of water and juicy fruit, cereals, laxative at bed time. In case of diarrhea try to include lots of water with electrolytes to compensate the loss of water, but try to avoid such thing to which you are allergic and allow bowel to rest. 

Try to drink lots of mild fluid, water, liquor tea, but it should either be warm or at room temperature. When you feel a little better you can include rice, cream of rice, mashed potato etc. when the diarrhea has totally decreased then you can come back to normal diet. In case of bladder disturbance you can control by drinking lots of fluid but once you suffer from this disorder you can consult a doctor for medication and relief.
